Green Business Ideas for the future Cities


During my recent visit to Birla Institute of Technology & Science, (Goa campus) I was given an opportunity to talk to a class of students on the synergy between Renewable Energy & Future technology with its potential business applications. Not being an expert in any of the subject, I considered the path of least resistance. That is to put forth a few Green Business Ideas and with the talent pool BITS has, if there would be any viability in my ideas, they would perhaps be the best bet to make them happen.

By default, I have never attempted to invent the wheel. It needs a superior mind to be the inventor. But, I have some confidence in exploiting a tool to its maximum benefit by tweaking it just a little. Thus, a few thoughts came into my mind.

On my last invite to BITS – Goa, I was fortunate to meet some of the best minds of the country which inspired me to come up with a thought which I penned down as Solar Laptop & Mobile : In your store by next summer? While researching for my impending lecture this time around, I found that the idea has already been implemented.(article). Not in the exact way I had written about but we already have a piezoelectric laptop and jogging shoe. And  among many inventors some of the protagonists are Indians too. The only feather missing was the name of a primer Indian institute. Its time the Indian Engineering students change that. However I was  glad to find young achievers in a lesser known Nagpur institution the Nuva College of Engineering when it came to the piezoelectric shoe (article). Here I found people who are already doing parallel research and achieving the same concepts.

I am not sure how many young minds in India are even aware of The National Innovation Foundation.? As with every meaningful governance tool, it too languishes in a dusty corner with no real attempt by the Ministry of Science and Technology to promote it among the masses in a sustained and populist way. If one sees the site, some of the products although brilliant, have not found currency in the fast modern megalopolis simply because most innovation have not reached the market, barring an amazing few.

The need of the hour is that we have a constant dedicated media, specially a visual media which keeps showcasing the excellent Green Ideas which is being thought the world over. If India can achieve this one single act, I’m sure that brilliant young minds would showcase more and more concepts of efficient living. It would and should become a platform for exchange between the academia : business doing a greater good to this resource depleted planet.

It is said that Ideas can save a life, believing in this I put forth a few more ideas to the students at BITS – Goa.

The first thing I said was that one could revisit the piezoelectric powered lap-top and see if they could harness  the ambient light emitting form the screen into small photo-voltaic panels fitted just above the key-board space. And can a battery also be developed which could convert the waste-heat into power? True the initial contraption may be an extension (accessory) rather than a part of the computer, but it would help extend the charge thus reducing drawing of power from the grid.

The concept could perhaps be extended to large computer Server Rooms. Server rooms by default have to be kept cool 24x7x365 thus a huge drain on electrical power to run air-conditioners. Therefore can it be possible that the heat being exhausted by the server fans be directed to a metal plate which has its other end super cool, thus inducing a current, which then forms part of the energy demand of the air-conditioners ?

While in 2009 Maxell did created a near recycled battery and also conceptualized the reverse supply chain, not much traction is seen on it. Simply because we always lack the money and might to do a good thing. The other day, while discarding a dozen coin cell / button batteries from my child’s toys I was deeply disappointed that none were rechargeable. And there was no shop or scrap-dealer ready to take them. Simply because they have no resale value, weighing between 1.9 gram to 2.6 gram the 10 pieces could have hardly moved the scale to excite a scrap metal vendor. However if the same calculation is applied as I did in the article Green Business Ideas – CDM methods for Steel Production.the result too would be in million tonnes of steel.

I wondered if the promoters of POSCO steel plant which is facing the ire of the Odisha villagers would consider, the idea of innovative recycle. But then we are always happy to rip and rape life-style and virgin land rather than think sensibly. After all most of us are intelligent human devoid of silly sentiments of saving Earth. We are smart enough, when the time comes to relocate to another living planet in the Universe! So what if we don’t have the address, we can always ask it from the doomsday cults who keep sighting aliens.

Bio-degradable batteries

So the next best Idea which young achievers could look at is bio-degradable cells. Already there is a lot of research on-going but I’ve yet to see a button battery which is bio-degradable. The thought itself is so exciting, because different branches of engineering students, within the campus can group together to devise the perfect tool.

Perhaps they could design a Mobile phone or adopt one of the path-breaking concept of a Grass -phone but add more piratical concepts and look to at it. Then engineer the battery area in a way so that button cells are no longer  required but the ones which are bio-degradable can be used. Even the new lithium-ion batteries which are paper-thin and bio-degradable need to be developed further to be made for mass consumption and cheaper. Which then can be applied to the host of  futuristic smart phone designs which are already being showcased. And to add on to the technology of Mobile phones there are two more areas of research. The first one is to develop an “App” which can control the cell-phone camera; when detached from the phone and stuck to a wall or placed on a table to shoot self-portraits. It is almost a necessity, which almost all cell-phone users must have faced one time or the other. The detached camera can be controlled for zoom and focus via blue-tooth while the applications helps set that perfect screen-shot with the desired back-ground. No more waiting for strangers to click ones photo, blurred or shaken and missing some vital elements the photographer would have wanted !

The second more closer to my thoughts is a simple layman friendly mobile phone application which could measure the ambient light in a room and rightly advice, post keying in the information as to how many lights and at what temperature the Air-conditioner should be set, vis-a-vis light transmission from the windows at day-time and the out-side temperature prevalent. This would make sense even in LEED certified building as because complete automation of lighting controls on an hour to hour basis is not yet prevalent and not all homes have the automation facility which one may find in offices, which are more given to better energy management.

While it can not be denied that institutions world over have some of the most brilliant innovations happening, the Indian scenario needs to improve further. As is the case of the piezoelectric driven laptop, where the Indian scientist are doing the research in Australia; we need more scientist doing research in India itself. It is only then we shall be able to have products which are cheaper and more affordable to the masses.

Ideas like piezoelectric should find currency and support from both business and government alike because the seer population of India would be a boon to such renewable energy development. It is time we have people looking at the applications of piezoelectric as the west is doing so actively.

And here the role of institutions become important in terms of indigenous design and development.

Recycle Rare Earth & Renew Energy


Through this article I would once more attempt to join the dots which would perhaps lead us to practice sustainability as naturally as breathing. To do this each of us must be able to co-relate as how seemingly diverse things dove-tail to one conclusion. The modern humans insatiable need, which without being tempered by understanding at the basic level would not lead us towards the very Millennium Development Goals we aspire Using just one product, my attempt is to put forth an idea, which used as a datum could hopefully be applied over a vast field of products by those who are more capable.

“Mobile communications offer major opportunities to advance human and economic development — from providing basic access to health information to making cash payments, spurring job creation, and stimulating citizen involvement in democratic processes,” World Bank Vice President for Sustainable Development Rachel Kyte said in a press statement. “The challenge now is to enable people, businesses, and governments in developing countries to develop their own locally relevant mobile applications so they can take full advantage of these opportunities.”

A July 2012 report – Approximately three-quarters of the world’s population now has access to a mobile phone, according to a new study from the World Bank. The number of mobile phone subscriptions has sky-rocketed over the past 12 years. Fewer than 1 billion mobile subscriptions were active in 2000, while there are six billion subscriptions active today. Last year alone, mobile users downloaded more than 30 billion apps. A study by the World Bank and infoDev titled “Information and Communications for Development 2012” found that worldwide mobile subscriptions grew from less than 1 billion in 2000 to over 6 billion. And mobile subscriptions in low and middle-income countries increased by more than 1,500 percent between 2000 and 2010, from 4 to 72 per 100 inhabitants.

Reading – Digging for rare earths: The mines where iPhones are born About 60 miles southwest of Las Vegas, in a mine some 500 feet deep, the beginnings of an iPhone come to life.But the sleek, shiny iPhone is far, far removed from the rocks pulled out of this giant hole, which looks like a deep crater on the moon. A very deep crater. The ground is covered with rust-colored boulders, rocks, and pebbles. The walls etched with striations in varying shades of black, are notched, every 75 feet or so, creating steps that only a giant could use to climb out of the pit….Inside the rocks from this mine are rare-earth minerals, crucial ingredients for iPhones, as well as wind turbines, hybrid cars, and night-vision goggles. Minerals such as neodymium are used in magnets that make speakers vibrate to create sound.….

As defined by IUPAC, rare earth elements (“REEs”) or rare earth metals are a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium.Despite their name, rare earth elementsare relatively plentiful in the Earth’s crust, with cerium being the 25th most abundant element at 68 parts per million (similar to copper). However, because of their geochemical properties, rare earth elements are typically dispersed and not often found concentrated as rare earth minerals in economically exploitable ore deposits. It was the very scarcity of these minerals (previously called “earths”) that led to the term “rare earth”.

We pause at the word – typically dispersed and not often found concentrated in economically exploitable ore deposit.and the words of World Bank Vice President for Sustainable Development Rachel Kyte.-..”to enable people, businesses, and governments in developing countries to develop their own locally-relevant mobile applications”..

Sustainable development as we know requires the principle of the three “P”s – Planet – People – Profit fitting perfectly with the four “R”s Reduce – Reuse – Recycle – Recover (energy).

  1. Wherever possible, waste reduction is the preferable option.
  2. If waste is produced, every effort should be made to reuse it if practicable.
  3. Recycling is the third option in the waste management hierarchy. Although recycling does help to conserve resources and reduce wastes, it is important to remember that there are economic and environmental costs associated with waste collection and recycling. For this reason, recycling should only be considered for waste which cannot be reduced or reused.
  4. Finally, it may be possible to recover materials or energy from waste which cannot be reduced, reused or recycled.

Empirical evidence suggests that by practising waste prevention, reusing products, recycling, and making environmentally conscious purchases, businesses can cut costs and increase profits. Cost savings take the form of:

  • Lower waste disposal costs;
  • Lower waste treatment costs;
  • Lower energy costs;
  • Savings on materials and supplies;
  • A reduction in regulatory compliance costs;
  • Lower storage costs;
  • Cost recovery through the sale of recyclable materials;
  • Cost recovery through sales of 4Rs technologies.

Now let us add two more” R”s – Refuse and Rethink.

While we all are attempting to practice sustainability, that it has still not percolated down to the grass roots is because we as a collective of Sustainable practitioners are yet to join the dots in a simplistic fashion. And unless we do so, the ground swell of awareness and true sustainable practice which is balanced with modern life-style will elude us. The concept of Sustainability can not be a placard which one can paste on the door of the office. It has to be from within us. The society as a whole must adopt sustainability in their consciousness. The Peoples must be identified as such; just as we associate Precision = German / Swiss; Adaptive = Indians;  Disciplined = Japanese; and other cultural stereotypes; the world as a whole must adopt it as a culture.

We as modern humans are so trapped in our system that while we say Sustainable Development, in the same breadth we also look to encourage Countries to develop Mobile Applications, without pausing to think that the very popularity and success of these applications would lead to another explosion of growth in manufacturing of Mobile phones and thus from 6 Billion in 2012 we would perhaps cross the 12 Billion mark in half the time it took us to reach the first 6 Billion.

From a World Bank perspective that is Sustained growth. From an Sustainable Development Goal, it is a prelude to doom, as the miners rub their hands with glee whilst ripping out the “rare earth” from the bosom of Earth and lay waste vast tracts of land. Which would take a Millennium to sustain itself again. No better anti- thesis can be found for the term Millennium Development than this.

So is the euphoria at the World Bank on the reach of the cell phone right to the grass-roots misplaced ? The answer is a resounding NO! Right from Disease Response; Education Through Games; Monitoring Government Accountability;  and Disaster Response; cell phones have a very positive impact and this achievement is set to grow over time.

But it becomes a little too much when Preserving the Rainforest as mentioned in the link is added to support it. The crony capitalism becomes evident. Although the very same mobile telephony can be used to create greater awareness on climate change. This boon itself is a curse, should we not also not make Mandatory for all mobile phone manufacturers to create a reverse supply chain management to recall each and every cell phone; when its stipulated usage life is over. 

And to believe that the people would do this out of altruism would be the biggest folly. One would rather have someone at e-bay buy it, than s/he walk down and put it into the recycle bin for free. That is how we all are. We are a market society conditioned by a market economy and we all are buyers and sellers. We can do nothing positive (or negative) unless we can see tangible benefits (profit) for ourselves.

While we teach our children the advantage of the R’s ( Learning the 4 R’s :Recycling and Rubbish Exhibit (R.A.R.E.) program teaches kids to reduce, reuse, recycle and rot ) why is it that the Corporates not adopting it. Or rather why is it that the UN unable to make it mandatory for all corporates to follow the rules, by declaring a resolution at the United Nations Security Council ? As in my last article, I firmly believe post the devastating Hurricane Sandy that Climate change become an agenda for the Security council rather than the UNFCCC.

That the 4 R’s has distinct advantages has already been highlighted earlier in this article. If we just take the advantages – Savings on materials and supplies; Cost recovery through the sale of recyclable materials; and apply it to just the cell phones let us see what we get.

A Mobile phone is made Gold, Silver, Tantalum, Platinum, Palladium, Lead, Tin, Copper, Plastic, Glass, Steel, Aluminium, Silicon etc. Coltan is used to make the SIM card. Now if we assume that in a year at least 50% of the 6 Billion Mobile phone users world wide change their handsets, the savings on material supplies and cost recovery through the sale of recyclable materials would be handsome.

What if this recall of Mobile phones is driven by one of the many arms of the UN, with active support from the NGO’s who have the depth of reach into the hinterlands of the developing world? NGO’s which are truly altruistic and would surely give value for money deals to the rural poor. And at the same time convince the city dwellers to also partake through school programs in this novel recovering of the Natural resources.

There is already a stellar example of this form Nokia, The need of the hour is that more people know about it and start doing something similar. And this is where the failure of the popular media to take up a cause which is really worth-while is completely underscored. And it also shows how less traction the UN gives to promote ingenious concepts, leaving it at the mercy of market forces which are hostile to change. A market based society can only look at every thing from its skewed logic of economics, which is responsible for the mess we are in today.

Nokia’s ‘Remade’ Cell Phone Made Of Recycled Materials – In February 13, 2008 Nokia’s CEO Olli-Pekka Kallasvuo unveiled Remade at the Mobile World Congress conference in Barcelona. The idea was to create mobile phones that cause less of a strain on natural resources, while reducing landfill and increasing energy-efficient production. A concept phone called “Remade,” which would be built almost entirely out of recycled materials. Phones based on the Remade concept were to be made out of metals from aluminium cans and plastics from drink bottles. Materials from old car tires would make up the phones’ rubber key mats. The phones were also to use environment-friendly technologies, including printed electronics and display graphics that save energy.

The above example shows how Corporate responsibility if truly applied can create a sea-change in how we look at our resources and develop sustainable ways to live our lives without sacrificing the comforts of modernity. I wish we would be able to see more companies follow. We must understand that our ability to sustain and survive depends on how we care for the planet. If we continue to create great wound ( mines ) on the skin of the Planet, somewhere and somehow there is bound to be effects which we can not fathom at present. And if we don’t think on those lines soon, it might just be too risky a situation later.

“Remade” is simply a concept for now and not a commercial product, but it demonstrates what can be done using nearly no new materials to build a mobile phone, said Nokia’s spokeswoman.

The above speech needs to change thus – “Remade is now being provided funds from the UN sponsored Global Climate Fund and we would encourage more companies to submit their ideas to avail the funding & market support (through mandatory resolutions passed) required to make their sustainable products economically viable” – a hypothetical spokesperson of the UN.

A clarion Call to Sustainable Living


A couple of days ago, I was giving a presentation as how through my firm I can provide Solar Photo Voltaic system to all Commercial and Infrastructure projects which require large amount of energy to operate.  And that too in an OPEX format, by that I mean I have investor backing who would want to become RESCO. Presently it is  on roof-top model. So Hospitals, Hotels, Malls, Commercial Complexes and Airports, Rail-stations etc, which have large roof-top can have power. It would obviously lower Diesel consumption, which is generally used for back-up.

The idea as I have mentioned in my earlier article Green Business Ideas – Applying Solar OPEX model on Green Buildings will make Grid parity easy. is becoming popular but when we want to scale, its facing the biggest road block of subsidised tariff on fossil fuel. Even when my concept of Solar OPEX is ready to handover ownership on the 10th -15th year, and only charging discounted tariff on generation, due to heavy subsidy in the industrial sector the idea just can not germinate under the intense competition from the subsidy. We can provide power to all at about INR 8.50/- but all arguments fall flat when the industry and in some states even commercial power is at INR 4.50 – 6.00/-.

Recently there has been an article which says that a lobby consisting of industry captains, NGO‘s and common persons are petitioning the UNFCCC meet at Rio, to come out with strong laws which would abolish subsidy on fossil fuel. And to be honest, this would give birth to the best Green Business Idea of this century.

Long there has been talk of how one must charge the true value of water, only then the waste of it can be limited. Longer has been the demand to remove subsidy from fossil fuel. Granted it is a political hot-potato, but if one shows a slight more maturity and instead of short-sighted goal explain to the people the farsightedness of this measure, I am sure people would understand. Unfortunately, mostly vote bank politics and corporate greed drive policy.That we have finite resources must be advertised with all the collective forces we can gather and impart that knowledge to all.

We must now begin to evolve an universal law. Not laws which govern different countries. Constitution of each country is different. What is crime for one can be heroism for another. How then we are the United Nations?Let there be diversity in approach to a solution but let laws that govern the sustainability of Earth be one. To be adopted by every member nation. It is only then we can have prosperity. It is not a tall task to achieve because, when 134 Nations can come together to force a recalcitrant Nation to subjugate, it can as well be applied to save the Earth from disaster.

Today our civilisation is in a cusp. It is time we move away from the era of Capitalist consumerism. Human history had many epoch – the stone age, the bronze age, the iron age. And Human Civilisation did thrive. Excellence was achieved. So much so that they still stand testimony in the name of Arayabhatta, Chanakiya,Confucius, Aristotle. In great monuments like the Pyramids in the Americas and West Asia, the monuments in Macedonia and Greece, the Great Wall and many more. They stand testimony to time. Sustainable thoughts & deeds and also sustainable buildings. Sadly today we can not be as advanced in thoughts as our ancestors, the reason is complete disconnect from Nature.

Though I do not advocate any religion, yet in paganism which was followed around the globe once, there was a direct connect to Nature. We must evolve ourselves into a collective which can rise above religion and creed, greed and short-sightedness to evolve a solution which is the NEXT CIVILISATION. An era where B-Crop are norm then exception and Sustainable is not a catch phrase but a human and corporate agenda.

Greening The HVAC Energy Supply


English: A huge double HVAC exhaust of an offi...

The HVAC &R industry is transforming and morphing itself to the needs of the current Environmental scenario. They are packing more efficiency with less energy consumption and maintenance needs. The home versions too are coming with intelligent functions and sleeker smaller sizes which blend with the décor. Yet there is one thing which the industry requires to truly make it, what the environmentalist can call a GHG friendly product. And that is tie it to a power source which is a RE (renewable energy) source.
Imagine the advantage, a major revenue consumer like the HVAC & R, would have as an impact to the market if RE could be packaged to it. Let us examine the possibilities and potential of this concept.
Renewable Energy source such as Geo-thermal (rock-heat essentially) combined with a Gas based electric source would be the choice where the premise has the space but not the roof-top which can hold the other RE-source that is a Solar +Wind hybrid.
This is a solution which the HVAC&R industry should study closely, especially in light of the new BEE norms that have come into play from the year 2012. While compliance to the law is a must, with a weak Rupee and a fluctuating consumer market innovation can be the only solution.

While the roof-top AHU’s can be designed to have SPV panels on top, it would only increase the cost of the product, while making some energy generation green. However if the HVAC &R industry tie up with the nascent SPV industry which are offering Solar Solution in the Operation Expense Format, it can revolutionize the market dynamics.
Let’s first understand the OPEX-Solar model. In this model the certain SPV companies are offering solution in which the total EPC and O&M expense is being borne by the SPV Company for a minimum period of 15 years before handing over the ownership of the asset to the user. All that the Solar Co’s are asking is the tariff as generated. Although this model is already a success on individual roof-tops and can be provided for up to 1MW on connected load, this requires proper Government support to be able to increase the load to above 2MW and at nominal wheeling charges.
It would create a win-win situation for both the HVAC&R industry and the Solar Photo Voltaic industry and a revolution in India in the Clean Tech – HVAC & R space.

Another area which the HVAC & R tied to RE can get advantage from is synchronizing their system to Diesel Generators. During Grid power failure, the captive power used to run the HVAC & R plants are large Diesel Generators and an expensive option. Diesel is used for various purposes. Trucks (37%), Passenger Cars (15%), Buses (12%), Agriculture (12%), Industry (10%) and Power generation (8%). If we add the last three we get 30% of the total diesel pie of which we can easily allocate 40% as to be utilized for use of HVAC & R, by these three industries, for the purpose of cold storage, shop –floor cooling & cooling administration offices. Therefore with HVAC equipments tied to RE, the industry create a space which has no parallel till date. And in the process opens up a funding line which was till now only given for Clean technology purposes.

Subsidy on GHG producing products and procedure must stop


Locator map of the state of Maharashtra, India...

The State of Maharashtra tabled its annual budget this week. Although on the face of it there is cause for worry, as some measures would bring in more inflationary pressure for the common man; the environmentalist in me was happy. Diesel, Petrol, Plaster of – Paris ( with which large Hindu Deity Idols are cast every year, and immersed into lakes & rivers, polluting them further; thus the idols will be cast with eco-friendly materials now ) have become costly. Electric vehicles have become cheap with no tax applicable. Wow ! Reva electric, I will visit your show-room soon. Yet there are areas which strangely the Government both at the Centre & State, choose to ignore. And that is related directly to our forest cover.

During my recent visit to a food processing factory, for data gathering and understanding the process, (so that I can design a  IGBC  “Green Factory” rated second unit ) I was aghast at seeing tonnes of chopped wood being used to fire up the boiler, which produces hot-water required in drying up the pasta in the moulding machine. Inspecting further I saw them using archaic, bakery kilns which need a lot of wood to produce the heat required, to dry another food product.

I offered to give them a 250KW Solar Photo voltaic pilot under OPEX format, to produce the electricity which would at least reduce the use of wood; it was politely declined. Reason – They presume wood to be cheaper as 1kg is sold to them at a paltry sum of Indian Rupees 2.50 /- , because even if I don’t charge them a dime for the solar panels; instead take a tariff for the electricity generated,  it would work out to be INR 8.50 /- per KW. Which is higher  than the e-DISCOM charging the industries at INR 6.80 /- per KW.

The boiler requires 55 kg per hour x 24 hour x 365 days !

I stood silently looking at the chopped corpses of trees, which were once alive and swaying gently in the breeze while birds and bees sang the welcome song to the newly arriving butterfly, bursting out from the shell of the pupa – hanging under a shady green leaf; and advised, how instead of throwing away the charcoal produced in the process of burning the tree – to use it again; its heat is more intense per Kg/Cal  then the wood.  While silently bowing my head to the trees which even post being killed and burned can help humanity in form of charcoal.

And I was angry. Angry at the system which only gives lip service to the cause of sustainability. Where no real measures are in place to curb the menace of chopping down trees for fire wood ; not for cooking meal of the improvised indigenous people living in the forest { they are persecuted by forest officials, who most ( if not all ) are in cahoots with wood smugglers } but for making pasta for the élite, who live in cities and take out candle light march to make the World aware of “Global Warming” ! Candles by the way is a GHG producing hydro-carbon.  Sad that no real and meaningful progress is being done to educate about  the actual cost of  electricity being provided cheaply by the state through coal-fired Thermal power plants.

While it is true that our modern economy has trapped itself within a vicious circle where we can not find easy answers for achieving a balanced and sustainable growth while maintaining the life-style we have adopted, it is equally true that unless hard measures are taken now,  our life would be styled to that of early cave-men in the near future. And the answer is No, if one is thinking it would be the fate of everyone. It would be only for those who would be unfortunate enough to survive the floods, droughts, famine and War that would be fought between countries for the best water hole !

I grieve,  when our leaders express that they have the mandate of the people towards development  which are inherently high -carbon; and my frustration is directed towards UNEP. Can they not devise a system wherein  they can get the mandate of the grass-root people around the World, which can stand as legitimate in the International court of Law ?  How can we create a sustainable economy when coal fired thermal stations and raw wood is being burnt by million tonnes per day, is considered to be cheaper than renewable or alternate energy ? How difficult is it to get a missed call, a sms and an e-mail endorsement which has some legal standing ? How difficult is it for powerful environmental groups, who have the ears of UNEP, to create an advertisement which all type of media can then carry as their CSR. Can they make more people aware of the thoughts of Buckminster Fuller and many such eminent personalities, who show the way towards transition to sustainable energy management ? thus mobilizing the people in understanding pertinent issues and then conduct a debate as whether the people are ready to burden their shoulders with hard economic choices, for a short term to be able to enjoy sustainable economy forever afterwards. And thus debunk the justification given by the elected representatives, who claim to know what people want ?

I have never for a minute believed that personal prejudice and bias do not creep into policy making. For every Politician & Bureaucrat is human first, not to be affected by the environment s/he must have grown-up in. And most often than not these people have over-riding ambition for self-promotion, before National /International cause, they endorse. And if that self is conditioned to feel comfortable in an environment, hard it is to break away from that familiar life-style which has provided all that they have today. And the familiar life-style sadly is high-carbon economy & the creature comfort it gives us till date.

When people are told that catastrophe would befall in the next 50 to 100 years, they laugh, and say – ‘enough time in hand’. The Taj is 358 years old and every day  hundreds of people travel back in time and come back, when they enter the gates of the Taj Mahal – 300 years is here and present ! So the effects of our inactions today will be felt by our own future generation, not too far in the distant future, for us not to care enough !

Therefore can’t the UNFCCC at the Rio+20, armed with concrete evidence in terms of Peoples endorsement towards a low carbon economy petition the UN to pass a binding resolution for all Nations to comply to green standards ? All  resolutions to bomb a country or pass stringent economic sanctions without a shred of evidence pass smoothly at the UNSC, but when it comes the time for UNFCCC – which has evidence of clear and present danger to the World, no resolution gets passed for economic sanctions on Countries which are doing very little in terms of climate change abatement. The UNEP would always lose out to UNSC in these matters as I had predicted in my previous article. Unless we all join hands, big and small organization, individuals and lay men to lay bare the critical situation we all would face, if lopsided environmental reforms continue deep into 2020, the red-line flagged by the SREX report as point of no return for disastrous Global Warming .

Challenges of roof-top Solar: Can we have make them more non-reflective ?


Every new idea faces some challenges. Those which can rise up to them quickly and even before they become problems are the ones which have a future. Many articles speak of some opposition to Solar Power plants. Some don’t want it to cover large expanse of land, while others find that it changes the scenery around their habitat, thus an eye-sore. Wind power too has faced similar problems.

India  has through its National Action Plan for Climate Change, brought about 8 missions of which 3  look at the direction of energy efficiency with scope for renewable. As the power plant through Solar, which is comparatively new in implementation, in India matures, so would the problems. And the problems it would face would be unique to it.

English: Solar One power plant in Mojave Deser...

Large solar-plant in India, would not face much problems as long  as they are  installed in low density, arid to semi arid regions, for now. Although it would be better for the investors to do the Environmental Impact Assessment and have back up plans for adaptation. And those  close to rural habitation, must also think of innovation in case pressure in land due to population density increase. Which is a definite possibility in India.

However, Roof-top solar; which in my opinion is the real game changer in the immediate future; would be facing issues which the Indian Solar industry has not yet perhaps anticipated . The problem would be from the potential hazard of glint & glare of reflected sunlight, especially in high-density Urban settings. ( even the large rural SPV plants would have the problem if directly under flight path of the air-force / aviation industry )  The sooner the manufacturers and all related stake-holders wise up to it the better it would be for all.

In my earlier article on OPEX Solar I have already started receiving tremendous response. Therefore, I am able to anticipate the issues which could come up first hand. Buildings in any city are of varying hight. Tall buildings overlooking clusters of row-houses or commercial centre like malls, cinema halls and even hospitals and schools. Typical settings where one can seek business in roof -top solar. More often than not, these roof installation would be of a fixed type south-facing system angled in accordance to the latitude of the city. The reason to make them face south is for receiving the maximum  sunlight as the sun traverses the sky from dawn to dusk. While this would ensure maximum power-generation, it would also generate maximum ire from the poor souls who would be occupying the buildings which would be bouncing the reflected sunlight. And the Indian summer, well to put it mildly is very bright indeed. Not only would it add to the glare, in-fact the reflected heat if intense could also damage PVC pipes and other materials, if preventive steps are not taken before hand.

So what are the precautions one must take to avoid this situation ? Some article have already covered this issue. However I am for the solution and not flagging the problem and leaving it there.  While solar panels are designed to absorb sunlight to convert it into electricity, most commercially available PV panels today lose about 4 percent of their potential power output due to light reflection from the front surface of the cover glass. Solutions are already on the way, with Honeywell launching the SOLARC anti-reflective coating in February 2011. SOLARC materials are based on advanced materials used in semiconductor manufacturing. They are transparent coatings that improve the light transmittance through the glass that covers photovoltaic, or PV, panels, thus increasing the PV module efficiency and power output. These coatings also significantly reduce glare from the glass, allowing the PV panel to better blend with its surroundings.

Here one needs, especially in India to educate the potential investor to be ready to invest a little more on the prevention and precautions with respect to glint & glare. Especially to avoid the opposition, the type I have posted as links through out this article. India, needs the power through SPV. It is the only way to reduce the carbon emission, which is sure to increase as the Country grows. And as all know, carbon emission is a politically loaded subjected. It can bring intense pain or relief in terms of international relations in the years to come.

Should we lose out on the potential of the Sun, which India has in abundance due to wrong application, it would be a tragedy for the Nation.

Coal corporations helping India’s Clean tech aspirations is becoming successful – a model more nations need to follow.


Renewal Energy Distribution Companies find it so difficult to work and grow.The primary reason being denial of open access system by the power supplying companies the unquestioned rulers. The resistance is natural although national policy says in time open access must be allowed to level the playing field and bring grid parity. These companies have spent a lot of money and effort into developing the infrastructures and letting the new RE guys piggy-back on them is not something which sound business policy advocates. Yet, these powerful “Goliaths” would fall and the “RE Davids” would rise. Sustainable Energy requirements is the call of the hour.

For Humankind, the preservation of self is the most supreme and any event or cause which would stand in its way would have to perish. Today the desperation for survival of small island nations and mountain states, being mostly small in size and economic might; not really being heard by the mighty nations and the supporting fossil-fuel corporation. But as the effect of Climate change is being felt and the associated business risk gets recorded within the mighty nations, along-with more businesses understanding that their economic salvation lies in marketing and manufacturing ecologically sustainable products, the fossil fuel led lobby’s influence and foot-print is bound to shrink.

And no one can stand against the might of the collective. History has proved it time and again. And when an idea whose time has come also gets the support of the powerful United Nations, crony capitalism and narrow national interest will lose. It is the writing on the wall.

But Indian ethos teaches compassion. Those who have provided energy to the world for the last 300 years must not be thrown out unceremoniously but shown the light. Just as it is difficult and confusing for a one mighty ruler to accept defeat and face uncertainty, so is the case of these Energy Czars. Redundancy is not a polite word.

So India has devised a way out. The solution although complex, the logic is simple – channel the oil / coal profit into R&D of Renewable Energy solutions.This is the reason why in India we have the NVVN .  In Mumbai, India; BEST ( Birhan mumbai Electric Supply & Transport Undertaking ) draws 10% of its Electrical power for supply from RE as mandated for development & support of RE.Such mandate is more or less followed by all states.

Moreover, no one imagines that in the next 50 years, oil / coal would vanish from our economy. While its use begins to diminish ( hopefully ) it would be wise for the companies to diversify and invest from now into the clean-tech. And in the present economic situation, buying could be cheap.Further they should help in easing the entry of roof-top solar / wind in the immediate future. This would free up their power for industrial use, while residential, school & malls could draw their power from the RE industry.

A win-win situation for all. Hope the model is adopted by Nations sooner than later.

Renewable Energy is viable..period.


The preamble

The power of raw sunshine at midday on a cloudless day is 1000 W per  square meter. We can turn this raw power into useful power in four ways:

1. Solar thermal: using the sunshine for direct heating of buildings or water.

2. Solar photovoltaic: generating electricity.

3. Solar biomass: using trees, bacteria, algae, corn, soy beans, or oilseed to make energy fuels, chemicals, or building materials.

4. Food: the same as solar biomass, except we shovel the plants into humans or other animals.

David JC MacKay

With the run-up to Rio+20 Summit and the UNEP driven Future Cities program the use of RE especially Solar becomes more and more important.

With the tremendous pressure all Nations are facing over Environmental Impacts from their citizens, who are getting more and more aware about the disasters non-sustainable living; Bangkok would be a very recent example; RE in all form would have to be accepted and assimilated main-stream. Let there be no confusion that the Economy of the world are driven by three basic needs from time immemorial – Food, Clothing & Shelter. I will deal separately the issues of Energy -Water in detail later.

Food – Requires energy, from plantation to processing to cooking.

Clothing – Textile industry are considered one of the high energy usage sector.

Shelter – About 40% of GHG (green house gas) comes from building related activities.

In many countries Sustainable Building design have been adopted in form of BREEAM, LEED, IGBC etc. Nations have committed to the UNFCCC agenda of keeping the world temperature from rising another 2°c. All that requires tremendous dedicated effort from all sectors.

And most importantly, busting the myth of negative Return on Investment (RoI) put forward by the fossil fuel industry.

The Argument

In my opinion, if the home I live in sinks under the sea because I refused to pay a little more now to avail RE sources for my energy needs over coal/oil, I don’t think myself much of an economist.

An economist is a person who plans for the welfare of generations to come, albeit his own. Given the fuel lobbyist are pandering to this very self agenda, however there is a small flaw – their path would just sink the landmass; not much of an economic playing field will be then left, for the future generation !

Having said that, let’s see if we can still make a case of RoI with using RE in its present economic form. Today the cost of generation of power is “compared to” the cost of generation of power via fossil fuel. This in itself is a flawed argument. As I’m not an economist, my examples would be simple. Also I would perhaps not be 100% accurate in my assessment.

Now to begin with my theory – Fossil fuel has been used as a primary source of energy since man learned to control fire; however it was during the industrial revolution with the advent of steam engine did the consumption of fossil fuel jump exponentially. But if documents are researched, energy from fossil fuel driven carts would not have been cheaper than horse driven carriages in the then predominantly agrarian era. Neither was flying over ship when its time came!

It was only by economy of scale that these things became “cheaper”. Also because they became popular, flying though costlier than travel by ship saved time, thus the merchant could do more business within the allotted time, than waste more of it via land/sea travel. So even if flying (even today) is costlier than sea/land travel, the business person calculates his RoI in the form of time saved! Now if for some reason the venture fails, then the RoI becomes bad. So for a successful business person air-travel is good RoI and for the other bad! So in lay-man terms RoI is a subjective matter. It depends on what is the datum of your argument. I have as yet to see any person who buys a fuel guzzling car ever calculate RoI. Therefore RoI is a concept which needs to be researched better.

Further warming up to this argument, how does one say that the cost of generation from Thermal power is cheaper than Renewable Energy? Does it factor in the destruction – ecological, social & physical (pollution leads to host of diseases)? Moreover, it can but consumed only once. You burn the coal or oil, it would not come back to you, and you can’t replenish it via any natural process. It can be argued that the paradigm of Business is different from literally logic which perhaps is what I’m professing. However with “Eurocracy” in serious danger perhaps all business models need to be restructured.

The Solution

Now, having vented my exasperation on the fossil fuel lobby’s clever wining technique, let us dwell on the subject of improving the reach of Sustainable energy production. Just as any new technology in its infancy faces teething trouble, so is the RE industry.

Amongst all, Solar is the most promising and perhaps therefore faces most challenges. Its plant efficiency factor is very low, it uses large surface area and the present technique of trapping the solar rays are perhaps cumbersome. But given dedicated research and analysis, it is perhaps the best bet. Because there are two things one can bet his last dollar on, the Sunshine and the Breeze. As long as the Earth is there these two would be available for sure.( so would geothermal & wave, but that’s another story) Having understood that, what can we do to make this industry stand on its own? For that we would need changes in mass thinking. Once that is achieved the political class would seal the deal.

To change the mass thinking we need to bring RE into their everyday lives. In India we have the Prime Minister driven Nation Action Plan on Climate Change. Through these the Government is trying to make at first the 9 Industry sectors energy efficient. However the Building Industry is untouched at the moment. Even then if amongst the 9 sectors (Aluminum; Cement; Chlor-alkali; Fertilizer; Iron & Steel; Pulp& Paper; Power; Textile & Railways) have role of the Building industry; as each need their HQ and other Administrative blocks for operations.

 If 10% of energy use for these industries on their above mentioned assets is made mandatory along with offsetting another 5% of energy use by their respective employees residence, we will begin with a massive program, which will truly bring in the scale required to make RE viable. Most importantly, it would act as a compromise. A compromise between the Government who would want NMEEE and PAT to be viable as soon as possible and the said Industrial sectors which is putting forth their argument of the trails & tribulations.

India should lead the SAARC nations in providing  Solar -RE for its rural and most importantly Tier-II, III & IV towns and cities. This is because, availability of roof-top to pattern of consumption; is complementary to each-other. That is, most of the residential buildings are single owner 1-3 storied buildings with ample roof and land area. Along with it the residents are yet to be “spoilt” by the crass consumerist life-style which the mega-cities of India have taken to, in its quest to become more “western”. They by default consume less energy and this itself becomes an advantage to put small systems on their roof-tops to amply fulfill their energy needs.

Already most countries are familiar with “Green Building” concepts through LEED / GRIHA / BREEAM etc. Energy efficiency is becoming important to sustainable living and the concept of “Green Power” is getting introduced by these rating systems. Here too through local legislation or voluntary CSR 25% of a residential complex (min 100 flats) power needs could be through Solar PV. This would translate to the power consumed by the lift, gate/boundary lights and other common space lighting. Though the need for space to power the demand may not get fulfilled by the roof-tops alone, innovative and practical ideas are available! In sustainable terms if say each & every society of say, a city like Mumbai, more importantly the affluent districts in the city adopt the Solar roof-top solution the State of Maharashtra can better manage its Energy problems.

Translate this concept to New Delhi, Chennai, Bangalore or Hyderabad and we can already see RoI of solar extremely practical.

Perhaps it can also inspire other countries to love Ra – the Sun God, as Civilization did when it began its journey!

Green Business Ideas: Solar,Wind power Ships while Geothermal beats recession away – Future RE


It is cold, freezing deadly cold in Europe. There is death. Both reported human deaths and others which go mostly unreported. Ask that to the farmer whose live-stock may have also suffered and the animal lovers, they too would have a story to tell. In a report, I read that some western European and former East block countries are not getting enough Gas from Russia. While we must honor business treaty and longterm business collaborations, we must also understand that traditional sources of Energy must be re-looked  and the potential for all types of alternate Energy must be vetted. Form this vetting the one that is the most practical must be given precedence over the rest, world wide. This is the only way to avoid the discomfort EU faces due to the shortage of energy in this harsh winter.

 I would like my readers to pause at the Alternate Energy  which may be different form Renewable Energy. To my mind man has yet to devise a system which can perfectly ape the Earth Ecosystem in Generating Energy in a T-ZED form. ( Total Zero Emission Design). For every activity we partake there would be some thing that needs to be – MINED – EXTRACTED – CUT  out form the Natural system. We have not yet become that “advanced” as the advanced Nations like people to believe.

Having said that, we must now see which among the alternate energy sources we can get the maximum, within the constrains of resources we have, be it – technological, social, political or combination of all. Solar, my beloved is yet a baby which needs to catch-up to its big brother wind, who is having the adolescent problems of its own in various countries. Micro – hydle although better than its father the large Hydle dams in mobility and not as cruel to devastate large Eco-systems by sinking them; is too weak to power cities. The logistics of Bio-gas is another story, therefore it can have regional success in mid-size generation. Wave technology has not yet caught on.

So while we wait for Solar to take its place under the Sun, which no doubt it would and even avoid eating up large swats of land by just floating on water, while keeping in mind to allow sunlight down below; and compliment Wind turbine which line the Oceans along the sea faring route, in large floats which allow ships to charge up their dynamos from one point to the next, thus limiting the use and carriage of bunker fuel; especially when they enter territorial waters form the Blue Seas. In fact these floating Wind turbines could act as buoys / light-houses too and being closer to shore more easy to maintain, while avoiding the socio-political problems it faces on land, we must at the UNFCCC level hail Geo-thermal as the Messiah for now.

Low temperature geothermal applications include space heating and in agricultural uses (greenhouse heating, the drying of fruits and vegetables, aquaculture and seawater desalination, and in spas), providing an ideal synergy with other widespread commercial ventures. As technological advances allow for the exploitation of lower temperature geothermal resources, found at just a few meters below the ground surface, the heating and cooling of water for domestic use, for instance, becomes highly viable and attractive. Such applications lessen reliance of non-RE resources, are highly reliable and cost effective, and emit far less carbon dioxide. Advantages of investing in Geothermal are many as there are a  wealth of geothermal resources around the World. This can provide emerging markets with substantial entry-stage opportunities due to wide variety of synergistic applications.

 And Messiah it could very well be for Greece. All the Greeks need to do is look towards  Santorini. It is the most famous volcano in Greece. The most recent volcanic eruption in Greece was Santorini in 1950. Greece has 752 hot springs which are popular tourist destinations.   Greece lies in a geographic position that is favorable to geothermal resources, both high temperature and low temperature. High temperature resources, suitable for power generation coupled with heating and cooling, are found at depths of 1-2 kilometres on the Aegean islands of Milos, Santorini, and Nisyros. Other locations that are promising at depths of 2-3 kilomteres are on the islands of Lesvos, Chios, and Samothraki as well as the basins of Central-Eastern Macedonia and Thrace.  Low temperature geothermal resources are found at the plains of Macedonia-Thrace and in the vicinity of each of the 56 hot springs found in Greece. These areas include Loutra-Samothrakis, Lesvos, Chios, Alexandroupolis, Serres, Thermopyles, Chalkidiki, and many others.

Geothermal power – the energy derived from stores of superheated water and steam in seismically-active areas – could, according to geologists, offer a realistic alternative to fossil fuels in the production of electricity and position the country as a regional leader in what is a growing global market.  According to an energy profile of Greece in a US Commercial Service report, there are up to 2,000MW of electrical output available from ‘high temperature fields’ across the country.

By the end of 2007 the installed thermal capacity of the direct geothermal uses in Greece amounted to roughly 75 MWt. Despite the large high-enthalpy resources in the active Aegean volcanic arc ,no electric power is produced from geothermal resources in Greece.  With  the existence of 30 geothermal fields in Greece – two of them sizable enough to produce at least 250MW of uninterrupted electrical power, Greece can not only pay its way out of the Economic crisis but also show the way to the EU Nations on how they could   meets its Kyoto Protocol and EU targets on greenhouse gas emissions.

The above story is also true for India, which does not even exploit its easily available recourses.  In fact Mumbai is practically sitting on it. Should the State Government of Maharashtra seriously consider the use and application of geothermal lying under utilized it could use the applications of geothermal energy, which  vary according to their temperature and include:

Power generation(θ>90 °C)

 Space heating (with radiators, θ>60 °C, fan-coils, θ>40 °C, floor heating systems, θ>25 °C)

 Refrigeration and air conditioning (using absorption heat pumps, θ>60 °C, or with water-cooled heat pumps, θ<30 °C)

 Heating greenhouses and soil because plants grow more quickly and become bigger with heat (θ>25 °C), and for protection from frost.

 Aquaculture (θ>15 °C) because fish need a specific temperature to grow.

 Industrial applications such as desalination of seawater (θ>60 °C), drying agricultural products, etc.

 Thermal spas (θ = 25-40 °C)

Besides geothermal fields, with today’s technology, heat from rock at a shallow depth, as well as low temperature underground or surface water can be used for heating and air conditioning.  Hot dry rock, which is found everywhere at depths between 3 and 5 kilometers, by artificial water circulation through it at a temperature of up to 150 °C . If the cost of energy is calculated over the life cycle of the system, geothermal heat pumps cost less than a system which consumes oil or natural gas.

Geothermal energy should be exploited in India where using Nuclear Energy is meeting with stiff social resistance, especially after the Fukushima daiichi incident in Japan . Moreover, it has been proved beyond doubt by the experts of Geo-thermal in India that setting up a plant would cost far less than that of Nuclear and produce more and safer energy.

The other advantage it could have over coal based thermal or large hydle generated power is its “portability”. The size of a Geo-thermal plant compared to the above two would be very small – generation capacity wise. Moreover it would neither flood vast areas causing socio-economic upheaval nor produce fly-ash a dangerous polluter. The only thing it emits is water vapor. However, in some certain trace gases are found which can be easily treated.

This portability has a very great business advantage, which perhaps power companies have overlooked. It is a fact that energy generation and distribution in India is far costly than the tariff applied.  Typically, domestic (24% of total power supply uptake) and agricultural (22%) enjoy cross subsidies from industrial (38%) and commercial (16%) users. Industrial and commercial users still pay 30-60% above average power price. Therefore if Geo-thermal plants are placed close to the industrial & commercial areas by the Private power companies, they would be able to evacuate and distribute power at a far cheaper cost, which would be beneficial to both.

Solar Laptop & Mobile : In your store by next summer?


Last weekend I was invited by BITS Goa Campus ( Birla Institute of Technology ) to give a talk on innovative business strategy in Clean Tech. It was organized by the students with their campus fest aptly named – Quark. G-Con as the green conference to which I was called is being held for the first time by the students. That this event was  to be taken seriously impacted me almost immediately upon being introduced to my co-panelists. Personalties, each with a body of work so profound, Ms Rishu Nigam -TERI, moderator Ms. Juhi Chaudhry of  CNN-IBN, reporter on everything related to environment;  and then the stars  Mr.Ravi Kuchimanchi ; Dr. Ritesh Arya; D.T. Barki; Mr. Atul Gurtu; people who have placed India on the world map with their thoughts and deeds.

Sitting among them, I was inspired and awed. And what inspired me more were the young and brilliant students of BITS, the future of India. This inspiration led me to ask both the students and the eminent personalities to devise a  model to propagate  the clean tech ideas which came into my mind, while listening to fellow panelists.

Self powered Lap-top. An inventor like Mr. Barki could devise surely a solar jacket for the Lap-tops which all the students carry. Imagine if a continuous power could be fed into a lap-top, unplugged and at 90%  battery, via Photo voltaic cells pasted on to the surface therefore unfettered, sensitive as a Casio calculators power panel, so even the ambient light within a room is sufficient? Even if it would be generating power say just 30% in total, it would still increase the battery driven operation time and at the same time reduce the need to plug it to a grid source. Scale it to a Billion laptops in use every hour which can produce 30% power, it is a respectable number in terms of GHG reduction. And when it comes to R&D surely another fellow panelist Mr. Raghvan, GM of Mahindra Solar;  a branch of the blue chip Green Company Mahindra; with international presence and owner of Satyam would like to do a dekho ( hindi; for -look ).

The same could be the fate of the future cell phones, why need a separate charger if one could integrate a semi-circular disk which winds a spring, which in turn applies pressure and excites a quartz ( http://en.wikipedia.org/wiki/Piezoelectricity ) and thus produces a small amount of charge, every time one moves? Remember the old Swiss  wrist watches – the automatic ones ? One never needed to wind it up. This was before cells were born into this world – small made of steel and having a cadmium heart; to be discarded without thought while the Earth is torn open to find more iron ore and methods sought to stop rivers to be poisoned by cadmium.  Coming back to a greener thought – could this be incorporated within the “hostler” that holds the mobile phone? Adding that small amount of charge that keeps the battery from going dead just when you need it most. Perhaps can be even a life-saver; all that a lost trekker needs to do is keep shaking it while making the S.O.S call. Will it save the Earth, count the number of chargers charging the phones around you, as you are reading this and multiply that with infinity – you can bet it would !  And yes perhaps the makers of the next Green Laptop / Cell phone could integrate this piezoelectric  right into the keyboards .  Is  Samsung /Sony / HP / Dell listening ?

Megalopolis like Mumbai has the perpetual problem of sewerage and power. Dr. Ritesh Arya could solve both with his path breaking solution to use the slush to produce steam and run a turbine. And this can be done anywhere as Lava is just under your feet!  Mumbai has its own at Ganeshpuri, then there is  Surajkund and many others, powering India could become limitless. And as the energy needs come form an infinite limitless source called – magma, the World is invited to dip there steel straws into the Earth core and drink aplenty. GHG can be contained. And very much before 2020. Will UNFCCC  at the Rio+20 advocate this for the GCF ?

Simple ideas are most profound and that came from Ravi Kuchimanchi in form of a hay box ( click on this link to see it ). Now, that  led me to think. This can lead to reduction of LGP gas use in the cities. How ? Simple. Ask  the  insulated hot box manufacturers  to design the same and market it. India today loses millions due to subsidy on domestic LPG and other fuel. If even 5% of the overall LPG use can be reduced, the figure would be large. (An amount which can perhaps be pumped back on rural development.) And it is always seen that once you give an innovation which is popular, the people innovate uses which could not have been thought by the inventor.

And speaking of India, a country of – jugaard ( loosely translated – rustic innovation ) one never knows what the next best thing could be.

Note: this article are for all those young minds, who need to understand that for a better world, one does not have to invent the wheel. Just add the wheel to the cart you make. 

A special thanks to the G-con team, especially – Soumaya, Madhuri, Ananaya, Gaurav, Sahil who helped me think this article.

Green Business Ideas – Using Solar Panels as Glass Facade can reduce Heat Island Effect in Cities and earn LEED credits


glass facade

In the past week I was interviewed by two News media both electronic & print which were very excited about a report by scientists from the National Environmental Engineering Research Institute (NEERI) India,  on Glass Façade Buildings in the City of Mumbai, India  and how it is raising the overall temperature by more than 17° C in the surrounding area of the building. Although it could be true, one must explore about how this problem be addressed without making ‘glass’ a bad building material. Things are not always black or white, therefore I would use this as an opportunity to once more showcase how Sustainable Cities  could be planned.

Glass has been a tradition building material for eons now. Colored glass was found from the Babylonian era and some of the most beautiful Churches and Cathedrals draw their prime beauty from the Stained Glass murals. Glass is the only single medium which allows the external environment into the room in a controlled fashion. Which means one can enjoy rain, snow or bellowing wind swaying the tree tops without getting wet or cold and having that curly lock of hair firmly in place.

Yet uncontrolled use of glass can create problems, such as raising the ambient temperature of the city/town and making it warmer. While extensive use of glass in building façade may be considered a good thing to counter the harsh winter experienced in the temperate regions of the World, it is foolish in Hot climes.

The reasons are simple. The word ‘Green House‘ originally meant ( before Global warming became popular) a glass house which kept the temperature warmer than the freezing  European cold and let some plants & vegetables grow. This happens because the heat from the Sunlight gets trapped within the space by the default property of glass.

While this is good for designing a building in say Norway or Alaska, where every drop of Sunlight would bring in the warmth and perhaps help save in reduction of energy consumption required for district heating, the same principle would require enormous amount of  district cooling which otherwise would have been normal in case of a hot and humid city like Mumbai or any other city with similar climatic conditions. And those large  water-cooled Air-conditioning plants placed on the roof tops to cool the buildings do so by pumping cool air inside the buildings while sucking the hot air away and out into the surrounding atmosphere. So a total glass building would not only throw more hot air out into the cityscape it would also use more water to cool itself. Yes, there is air cooled A/c plants too and high-efficiency COP’s have the ‘Green’ label attached but it too consumes energy and heats the sorrounding it however saves on water. Only the most well designed and high-end commercial glass façade buildings conform to all Sustainability criteria. But it does not hold true for all.

Therefore while the building may look swanky and very western, I would caution the tenant in buying space there as their energy bills could shoot up. Moreover by default of design constrains, its cheaper to make the Glass Facade buildings near hermetically sealed. Further no one would want the Air conditioned space to get warm because of a leak in the window casing.

Now the above observations lead to some unique problems for India or for any Emerging Economy in the Third World with similar climatic conditions.

First is the heat & dust. Not only does glass buildings get warmer inside it turns ugly on the outside too because of the perpetual dust. And once the commercial buildings are sold it becomes the building owner association responsibility to take care of maintenance. Maintaining tall glass façade building does not come cheap. It requires a whole new engineering solution, such as façade cleaning lifts and trained people to do it.

Second, we are a ’emerging economy’. Which means only a few rich & super rich have the luxury of having uninterrupted power. Rest are routinely treated with planned load shedding / power cuts and have to generate their own power through fossil fuel smoke belching  Diesel generators. In case of longer duration of power failure, rationing is done to cut cost and even the generators are shut down. And in this case one has no choice but to sit in airless rooms breathing Carbon –Di– Oxide exhaled by the neighboring colleague and hoping to survive the day.

Third, in smaller Tier -II & III towns and even the cheaper business districts within the megalopolis  the buildings only ape the Glass Facade exterior with no  Fire Safety Norms as a priority, and are built by unscrupulous Builder developers who themselves are an ignorant lot along with little or no understanding of EHS ( Environment – Health – Safety ) nor it is understood by the general public. ( the whole of India has only 2-3 dedicated burns center, one in Mumbai. New Delhi has none. However thousands die each year through burn related accidents) . So Glass buildings which are not designed well may lead to catastrophe in case of fire. Further as some are built right upon the road-side in high density areas, during Earthquake or other calamities, it may only compound the problems further with razor-sharp glass falling all over. True the glass have built-in safety feature to shatter into small bits but bad fixing and poor quality glass do not perform as intended.

Business and Scientific report do not go hand in hand. But  Science must be heeded if Business is to thrive. Global warming and its associated risks are too well documented to be ignored.  ( read my article for details:  Climate change – the most significant emerging risks facing the world today ) If the City of Mumbai or any city with similar climatic conditions continues to grow in this fashion and Glass façade buildings become norm and not exception, we are looking at a serious problem.

So we come to the question of what would the Developers and the Public do post reading the NEERI report ? Will tall glass façade building vanish from the cityscape? No chance.

But saving Mumbai ( and other cities ) is a must. Therefore here I will present an alternate thought which the Glass manufactures like ASAI, MODI etc along with the Solar PV manufacturers would I hope discuss over cocktail & dinner and come back with great Eco Ideas which would at least help reduce the problem of Heat Island Effect. And for this we must look at BIPV.

CIS Tower, Manchester

Image via Wikipedia

Building Integrated Photo voltaic (BIPV) has been around for sometime. It produces electricity and can also act as a Glass Facade. (As the image to the right shows, the dark blue glazing with a logo on top )  Now this is an option which has not been explored to its full potential in India and the rest of the World because of the cost verses production of electricity. It is generally understood that BIPV which is still in its nascent stage needs to develop further to truly become the choice for Architects and Builders to consider using it as an alternative to Glazed Building. This can happen only when the cost of the product becomes near equal to that of conventional Double Glazing Unit ( DGU ) which we see all around the city of Mumbai. However we can speed up this process by simply bringing in the economy of scale.

So how does one bring about this economy of scale? Simple, by introducing the Green building concepts which require the use of Solar Power or Green Energy. Both in the TERI – GRIHA  and IGBC -LEED certification process require  to bring energy efficiency of about 14% to the Building Envelope ( skin of the building; the outermost wall /glass surface ) which  at times design constrain and economic factors make  very difficult to deliver. Further Green Building Norms also ask for 10% of the total building energy be drawn from Solar Power. This too, is difficult due to unavailability of required roof-top space in certain cases.

BIPV

Now BIPV  are SPV  (solar photo voltaic) patches of  modules which is sandwiched  between glass.  It not only produces electricity but also reduces the amount of Sunlight from entering the building which is known as the SHG factor for glass ( Solar Heat Gain). So this can act like ceramic frit-glass, which too is an architectural favorite as it has lower SHG factor  and yet have dual function. Further in the Green Building rating system one looks for high SRI  (surface reflective index) content to reduce the heat island effect. Glass has high SRI index. So it reflects more sunlight away and what could have entered the building unhindered gets caught and converted into energy by the SPV cells. So another LEED credit point, credit interpretation could be sought jointly by the SPV as well as the Glass manufacturers.

Now as more and more buildings all around the world are opting for LEED Certification ( Leadership in Energy and Environment Design ), the above two credit points would fit well into the scheme of things. But this may not be enough to reduce the cost of  BIPV. Therefore we can adapt the idea which I have explained (in the article – Green Business Ideas : Cheap Solar Power is possible  ) earlier to manufacture cheaper BIPV’s  and yet creating space for newer research & development. Therefore what NEERI published as a problem can be solved by scientific ways and high-end engineering which follows the basic principles of Sustainable Building Design. And who knows one day we may have enough BIPV clad Green Buildings just as the above French building ( click on image ) which would help further reduce the enormous Carbon Footprint each City has, to make a safer Earth with better business ideas.

Renewable Energy – Formula for Cheaper Hospital bills and Cleaner Air


Hospitals require enormous amount of energy to run. No hospital which take care of critical illness can have even for a moment not have power supply .  So  the light bulbs, fans and small exhaust and most importantly those plug points holding the mobile chargers. Yes! the Mobile charger, though individually does not amount too much power load, when multiplied a few 1000 times it matters! And trust me no ward waiting upon a patient  in the hospital wants his Mobile battery to be out of charge! These along with Computers care clubbed into the LDP, while the Air-conditioners, Di-humidifiers and filtration plants along with hot-water boilers is connected to the HDP. In engineering terms used in my country we say LDP & HDP ( light and heavy-duty power  ). And above all the breathing apparatus, operation theater machinery are  critical activities that can’t be stopped even for a Milli second. Therefore hospitals are designed with huge diesel generators for back up power.

Diesel generators ( even the “greenest” one ) belch fumes and make noise. What could be more ironical than Health Care which is supposedly to remove pollution ( as all disease can be termed ) form the Human body is perhaps inadvertently becoming party to Climate Change. This I’m sure no self-respecting and thinking Health care professional anywhere  around the World would want.

Renewable Energy can be the Messiah  for this, yet it is too costly today for all well-meaning Health Care institute to afford. And Government subsidy is not the answer. Because subsidy is not sustainable unless it has a practical back-up plan. So what can be done ? The answer in my humble opinion is simple. Take it to the people.

Everyday there are thousands of patients who visit hospitals and are cured of their malaise; thankful for a new lease of renewed life many donate to charity, some donate to the hospital. If this simple idea is taken forward and ( with a clear and transparent with proper accountability – especially for India ) each patient were to be asked to donate say between 1% to 10% of the total Hospital fee as Renewable Energy Cess, within a span of say 5 years almost all Health Care Units would perhaps become near self-sufficient in their daily requirement of Energy.

And why would the public pay up ? Simple again, convert each persons donation  into some kind of equity, so every time s/he visits and pays the RE cess, s/he becomes a partner to the energy plant. Now as the energy plant would reduce the overall energy bill the hospital pays over time, an expense it passes on to its consumer ( read patient ) the patient should benefit through a rebate on his/her bills! It’s a win-win situation for all. And it could be  modeled on other service industries too !

The State/Country benefits; the consumer & hospital benefits and most important  the Earth Breaths a little better !

True the problem of space for installing Renewable Energy Plant near the Hospitals may not be possible to solve at most time, this is where the Government subsidy should focus. To wheel in the power created by the RE power plants afar, through its established Grid and not charge the hospitals for it.

It would be also freeing up the traditional Grid power supply and thus create a ‘surplus’ for the Government to supply power to other areas and help Emerging Nations to develop further and for Developed Nations the idea could help in reducing their GHG emissions.

Technical Manual for Sustainable Site Documentation.


SUSTAINABLE SITE DESIGN:

The purpose of sustainable site planning is to integrate design and construction strategies by modifying both site and building to achieve greater human comfort and operational efficiencies. It charts appropriate patterns of use for a site while incorporating construction methods that minimize site disruption and the expenditure of financial and building resources. The process is based upon the premise that any landscape setting can be analyzed and studied as a series of interconnected geological, hydrological, topographic, ecological, climatological, and cultural features and systems. Selecting a building site begins the process of calculating the degree of resource use and the degree of disturbance of existing natural systems that will be required to support a building’s development.

SITE ANALYSIS AND ASSESSMENT:

Site assessment is a process that examines the data gathered and identified in the site analysis, assigns specific site factors to hierarchies of importance, and identifies, where possible, interactive relationships.

Data collection:

Technical site data –

Geographical latitude (solar altitude) and microclimate factors, such as wind loads

Affect building layout, including solar orientation and location of entrances, windows.

Topography and adjacent landforms—Influence building proportions, wind loads, drainage strategies, floor elevations, and key gravity-fed sewer-line corridors.

Groundwater and surface runoff characteristics— determine building locations as well as natural channels for diverting storm runoff and locations of runoff detention ponds

Solar access—Determines position of building to take maximum advantage of natural solar resources for passive solar heating, day lighting, and photo voltaic.

Ai r-movement patterns, both annual and diurnal— particularly influence sitting of multiple structures to avoid damming cold moisture-laden air, or blocking favorable cooling breezes during periods of overheating. Properly measured wind loads and pressure differentials are essential for designing interior air-handling systems or use of passive solar cooling strategies.

Soil texture and its load-bearing capacity—Determine building location on the site and the type of footing required. Identify site-grading processes by the soil’s potential for erosion by wind, water, and machine disturbance.

Parcel shape and access—Affect a site’s capacity to accommodate a proposed development, even if its size and environmental\ factors are favorable. Potential access points should not burden lower-density or less compatible adjacent land use. Zoning setbacks and easements can also affect development potential.

 Neighboring developments and proposed future developments—Affect proposed project and may lead to requisite design changes.

Analyze specific characteristics of climate zones: Climate has specific characteristics requiring mitigation, augmentation, and exploitation; there are 5 climatic zones in India.

Analyze the site’s existing air quality: Most state require an environmental impact assessment (EIA) outlining the potential negative impacts of a proposed development and how they might be alleviated. Site planning requires two kinds of air-quality analysis regarding: (1) assessment of the existing air quality of the site to determine the presence of noxious chemicals and suspended particulates, and (2) projection of the negative consequences (if any) of the proposed development on existing air quality. In primarily commercial or industrial areas, poor air quality should be a key factor in determining site suitability and use, especially for such facilities as schools, parks, or housing for seniors. Testing should anticipate seasonal or diurnal wind patterns to make certain that the worst possible case is tested.

Perform soil and groundwater testing: Perform soil tests to identify the presence of chemical residues from past agricultural activities (arsenic, pesticides, and lead); past industrial activities (dumps, heavy metals, carcinogenic compounds and minerals, and hydrocarbons); and any other possible contamination either on or in the vicinity of the subject site.

Test soil suitability for backfills, slope structures, infiltration: The native soil should be tested to determine bearing, compactability, and infiltration rates, and, in turn, structural suitability and the best method for mechanical compaction (i.e., clay soils require non-vibrating compaction and non-erosive angles of repose for cut-and-fill slopes).

Evaluate site ecosystem for existence of wetlands and endangered species: Preservation and restoration strategies require thorough economic analysis, specialized expertise, and sound baseline data gathered through both remote and on-site sensing methods.

Examine existing vegetation to inventory significant plant populations: This will enable the developer or owner to later specify vegetation that is susceptible to damage during construction, so that protective measures can be developed and implemented.

Map all natural hazard potentials (such as winds, floods, and mudslides):Eberhard Bosslet - Since 1983 - works with rui... Historic flood data, wind-damage data, and subsidence data should be mapped along with current annual wind and precipitation data.

Diagram existing pedestrian and vehicular movement and parking to identify Patterns: Existing traffic and parking patterns in areas which are adjacent to or near the site may need consideration in relation to proposed building design and site circulation patterns.

Review the potential of utilizing existing local transportation resources: Explore the sharing of existing transportation facilities and other resources, such as parking and shuttles, with existing institutions. This can lead to greater site efficiencies.

Identify construction restraints and requirements: Special construction methods may be required because of local soil condition, geology, earth-moving constraints, and other site-specific factors and constraints.

Infrastructural data

Analyze site for existing utility and transportation infrastructure and capacity: Existing infrastructure should be analyzed for integration into the building and facilities.

Historical Data

Review architectural style of the area for incorporation into building: If desirable, the architectural style that is historically predominant in an area can be reflected in the building and landscape design, enhancing community integration.

DATA ASSESSMENT  Illustration of a level spreader installation ...

Identify topographic and hydrological impacts of proposed design and building use: Measure cut-and-fill potential and assess potential for erosion, siltation, and groundwater pollution.

Develop general area takeoff and overall building footprint compatibility with site: For example, measure total site coverage of impermeable surfaces to determine thresholds of run-off pollution potential (i.e., over 20 percent impermeable coverage of gross site requires mitigation to clean storm water before it enters drainage system off-site). Footprint should also maximize site efficiencies with regard to required road, utility, and service access.

Identify alternative site design concepts to minimize resource costs and disruption: Develop several alternatives to explore optimal pattern with regard to factors such as grading and tree-clearing consequences and resulting infrastructure costs.

Review financial implications of site development, building, and projected maintenance costs: Total cost of the project must factor in ongoing costs associated with the site design, development, and operations, as well as hidden embodied energy costs associated with specific materials.

DeveloUS Air Quality Index Map-1/23/2009p matrix of use and site compatibility index: Each site may be assessed to reveal its development compatibility index with regard to a specific type of development. This index may reveal a pattern of incompatibilities thereby specific appropriate mitigation measures are undertaken.

Obama’s Better Building Initiative – a lesson for India


Some where in February 2011 President Obama of the USA, lauched the Better Building Initiative. He laid out his vision for winning the future by investing in innovative clean energy technologies and doubling the share of electricity from clean energy sources by 2035. Alongside that effort, the President is proposing new efforts to improve energy efficiency in commercial buildings across the country. Tax breaks, grants and loan guarantees will be among the initiatives to increase energy efficiency in commercial buildings by 20 percent in the next ten years. The President’s Better Buildings Initiative will make commercial buildings 20 percent more energy efficient over the next decade by catalyzing private sector investment through a series of incentives to upgrade offices, stores, schools and other municipal buildings, universities, hospitals, and other commercial buildings. This initiative builds on USA’s investments through the American Recovery and Reinvestment Act (ARRA), and its  continued commitment to passing the President’s proposed “HOMESTAR” legislation to encourage American families to make energy saving upgrades in their homes. Improving energy efficiency in  buildings can create jobs, save money, reduce USA’s dependence on foreign oil, and make its  air cleaner.

In India we started practising LEED about 6 years ago and in the last 2 years also developed the National rating for Energy Efficient Buildings – GRIHA. We were perhaps the first few who understood the importance of Climate change and ratified the Kyoto protocol. In a poll on awareness about global warming, India has a rating of above 50%. Yet the USA which has not signed the Kyoto protocol and perhaps is one of the biggest polluter would surpass and excel India in its effort to make Climate resilient cities.

Simply because of the failings of our political class. The seer arrogance and blinkered approach it has towards any fresh ideas and its tendency to pat itself on the back on presumed achievements. The Government talks of creating world-class cities and hardly any original thought is applied, confusing and dogmatic approach is taken towards any town-planing which stifles growth and  breeds corruption.

If the Government chooses, it can make an effort to redevelop our cities in the same lines of President Obama, and give a new lease of life to our overburdened metropolises and at the same time create new job opportunities.The 12th JNNURM Jawaharlal Nehru National Urban Renewal Missionis on the anvil and serious thought on these lines must be given if we wish to create a safe and economically vibrant country.

Building A Low Carbon Economy with Energy Efficient Buildings


GHG emissions from building construction, reno...
Image via Wikipedia

The building sector can and should play a role in achieving the deep GHG reductions that science tells us are necessary to combat the threat of global warming. The building sector contribution to GHG emissions is mainly driven by its end use of, or demand for, electricity. This is a key difference from many other sectors where the main issue is emissions from the supply of energy. The building sector as a whole could reduce its share of GHG emissions by 30-35 per cent whilst accommodating growth in the overall number of buildings by 2050. This can be achieved by using today’s technology to significantly reduce the energy needed by residential and commercial buildings to perform the same services. For example, by replacing equipment with more energy-efficient models, at the natural replacement rate, and upgrading the performance of the building shell.

Detailed ‘bottom up’ analysis of energy efficiency opportunities suggests that net cost savings can be achievable in the medium to long-term. Rather than a cost per tonne of GHG abatement, many energy efficiency options have a positive financial payback in addition to providing abatement benefits. The payback period, can vary from a matter of months to many years. This finding is consistent with a large collection of case studies within the Country and overseas. When coupled with a broad-based GHG abatement target and a supporting policy environment, additional energy efficiency investments by the buildings sector would reduce the costs of change for the building sector and the economy at large.

Despite being cost neutral in the medium to long-term, achieving the additional GHG abatement action from the building sector faces challenges as well as opportunities.

1.Adopting energy efficiency strategies requires upfront investment by businesses and households to become more energy-efficient.

2.The benefits, or payback of these investments, are gradual, accruing over the medium to long-term, as savings on energy bills.

3.The building sector will need some additional incentives to overcome the impediments to change. These need to address a range of issues, such as the need to spur behavioural change, particularly to encourage adoption, and to offset the required upfront, direct capital expenditures.

4.Essentially, there is a need to encourage the rebuilding of our current building stock to upgrade the energy efficiency of assets within buildings to deliver a more   sustainable outcome.

5.The pay-off from investing in the energy efficiency potential of the building sector would flow through the entire economy by reducing the cost that others would face to  achieve their reduction in GHG emissions.

It is vital for government and the community at large to recognize the evidence showing the valuable role that demand side management and energy efficiency in the building sector can play in GHG abatement. Significant gains are available now without the need to invent and apply new technologies. They do not involve substantial risk or uncertainty and would provide significant gains now and into the future.

THE BUILDING SECTOR

The building sector can be viewed as being comprised of two broad elements:

Residential buildings — housing the population; and

Commercial buildings — housing a range of activities including retail trade, accommodation, business services, government and government agencies, recreation and cultural services and industry, which represents around two-thirds of national employment.

Component parts of the building sector are noted in chart

Residential Building Commercial Building
Detached housesAttached dwellingsBuildings containing two or more soleoccupancy units Wholesale tradeRetailAccommodation, cafes and restaurantsCommunication servicesFinance and insuranceProperty and business servicesGovernment administration and

Defence

Education

Health and community services

Cultural and recreational services

Personal and other services

The estimate of greenhouse gas emissions due to energy consumption in the building sector takes account of:

1.  the amount of energy consumed;

2. the mix of fuels used;

3. the average greenhouse gas emissions from the different fuels (electricity is treated as a fuel); and

4.upstream emissions from transmission and other activities.

The electricity consumed within a building is only a part of the energy used to support that demand. A large amount of electricity and greenhouse gas emissions is also involved in distribution, transmission and generation. When reducing demand for electricity it is practical to eliminate the need for this upstream energy use and GHG emissions.

A larger proportion of GHG emissions are attributable to the building sector than its share of energy use because the building sector uses greenhouse gas intensive energy. Notably the building sector energy end use is dominated by electricity consumption which is dominated by coal fired generation located at the end of long transmission networks.

Emissions from the building sector are broadly of the same scale as emissions produced by the entire transport sector.

THE ABATEMENT POTENTIAL

The building sector could reduce its GHG emissions by 30–35 per cent by 2050 on an economical basis. Economic in this context means that the initial costs would be offset — and in many cases be more than offset — by subsequent energy savings over time.

The potential for increased energy efficiency in the building sector has been estimated through a bottom up analysis to identify energy efficiency opportunities in the building sector. The analysis:

1.Examine like-with-like replacement of energy inefficient appliances and building services with more energy-efficient equivalents;

2.focus on additional application of existing technologies;

3.take into account the costs of change and the expected benefits from reduced energy costs; and

4.factor in expected population growth and sustained economic growth which tends to bring pressure for increased energy use.

For the potential energy efficiency investments a much wider range of options exits. This set, however, generally represents the diversity of existing, mature technologies.

In the residential sector changes can be achieved through:

1. substitution for more energy-efficient light fittings;

2. greater use of natural light;

3.substitution for more efficient refrigeration;

4.adoption of more efficient hot water appliances with solar where possible;

5.adoption of appliances with a low standby energy use;

6. the introduction of more efficient heating and cooling mechanical systems; and better insulation.

In commercial buildings substantial savings to both costs and greenhouse gas emissions could be generated by:

1. improving air conditioning systems efficiency and including ‘economy’ cycles;

2.use of natural ventilation where possible;

3. the use of more efficient office appliances;

4.better insulation;

5.improved heating and ventilation;

6.the use of efficient light fixtures;

7.upgrading to more efficient water heating systems; and

8.where possible use of co-, and tri-generation (that is, using heat discharged from on-site power generation for water heating, and for absorption air-conditioning etc).

Energy efficiency measures would take time to be adopted by households and business. Analysis of the technical possibilities suggests the potential for GHG abatement is between 57 Mt and 66 Mt per annum by 2030. This would increase to between 86 Mt and 98 Mt by 2050.

Facts

• Buildings’ share of final energy consumption: 30-40%

• Global CO2 emissions from energy in buildings (2005): 9Gt

• Estimated growth by 2050 in all 6 EEB regions: 76%

• Growth in global population by 2050: 2.7 billion or 42%

Many energy efficiency projects are feasible with today’s energy costs. At energy prices proportionate to oil at US$ 60 per barrel, building energy efficiency investments in the six EEB regions (Brazil, China, Europe, India, Japan and the US) studied, totaling US$ 150 billion annually, will reduce related energy use and the corresponding carbon footprint in the range of 40% with five-year discounted paybacks for the owners. A further US$ 150 billion with paybacks between five and 10 years will add 12 percentage points and bring the total reduction to slightly more than half.

There are three key elements to

achieving progress:

– Use less energy

– Make more energy (locally)

– Share surplus energy (through an intelligent grid).

The most significant, long-term gains will come from using less energy.

Note: The data has been collected form various noted publications and condensed for easy understanding.
