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 Certification for Interior Design

Logo of the World Green Building Council, whic...

World Green Building Council

A lot is being done in the field of Green Building. New rating systems are coming up around the world. What started out as LEED– US, spread to LEED -Canada, LEED –India {IGBC} etcetera, today we have a World Green Building Council. The UK has its BREEAM, Australia & New Zealand have their own rating, Singapore and the far east also rate their buildings.

India also has a rating system designed under the command of the Government of India, the GRIHA. Showing India to be a very progressive and mature Nation with regards to its understanding & supporting the cause for abatement of Global warming.

But while, including LEED-India & GRIHA  rating give importance to Architectural / Civil- Structural efficiency along with Lighting & HVAC energy reduction in their quest for rating the building for its “greenness”  not much is being said about the interior design. Other than in LEED -US, which has a commercial interior rating called LEED-CI but that is all there is, according to my knowledge. I may stand corrected in this and would be happy to know of any other green interior rating.

The reason Interior Design,  a very very big and lucrative market World over; does not have a stand-alone Green rating of its own is because most of the existing  “Green” ratings presume that the subject gets automatically dealt with when one does a “Green Building”.

Well this presumption is correct to an extent, such as in selection of bath  & toilet fixtures which generally conform to the requirements stipulated for water efficiency, to recycled tiles, certified wood, low-V.O.C paints, LED lighting, low SRI carpets, star rated A/c etcetera. But for me, this should not be the case. I don’t see this as a complete solution at all.

Now lets see how much of it gets done in India. Not much to speak of !

Both LEED-India & GRIHA are in there early years, the knowledge and idea about them amongst the Building & Construction Industry is very limited, pan India. A few good developer/ builder do practice it. However, most have rudimentary to nil knowledge.

With this being the situation when it comes to construction of “Green” Building, I would rather call them Energy Efficient Building {EEB} to avoid any confusion as to the purpose and intent; it is hardly surprising that we do not as yet have a rating system which will cater specifically to interiors.

Yet every day we have some high-end show room opening which displays furniture, wall & floor tiles, Italian marble & granite, Egyptian carpet and et al. Do these furniture & tapestries with there high -gloss and stain free coating get checked for there Environmental friendly approach?

Don’t  the teeming, so called high end and those who aspire to be high-end Interior Design Consultants, who rip apart perfectly well done interior finishes in the houses of the rich & the famous and toss out every inch of wood -work, stone, highly toxic paints scraped from walls etcetera, need to be aware?

Aware that their actions are detrimental to the planet? Should not they also be educated on the mantra of Reduce – Recycle – Reuse? The three “R” are the basic principals of a “Green” or to be exact an Energy Efficient and Sustainable design.

It would in my opinion make immense Economical & Ecological sense if both IGBC and ADaRSH  the  Indian institutions responsible for the LEED-India and GRIHA rating system start to think about creating a – Green Interior Rating which can rate both commercial & residential projects.

India would be left richer as a sustainable Nation should awareness in Green Interiors is mooted. As one must remember homes & office premises are usually bought once in a life-time of most Indians but Interior design usually happens once in 5 years; either at one go or in instalments most Indian homes see this change.

It is time we think of doing something right about it and make the world a little more safer for our children.
