An Important Reason to Use More Solar and Wind Power - Dwindling Water Supplies for Cooling

Wartsila, one of the world's most important generation system manufacturing companies, points out a huge problem facing conventional generation systems around the world - dwindling water supplies for cooling. This is especially important in the case of nuclear power and in coal fired thermal powerplants. While locating powerplants on the coast in order to use sea water for cooling would help to some extent, the problem would be in investments, maintenance and more in supplying the electricity generated deep inland in different parts of the world. The problem becomes worse in capital-short countries like India that have huge problems with power. The solution, then, is to use localized sources of energy that do not require water for cooling, which means wind and solar power. Wind energy is not cheap, and it may not be practical everywhere. In regions that receive more than 4 hours of sunlight for 325+ days a year, current solar PV prices are certain to help. There would also be a need for smart grids to integrate the solar / wind power with whatever baseload source is used, but that is something that could be addressed when the wind / solar generating systems are being installed. PS I do know that water use could be reduced by using sodium or other coolants, but have to wonder about the added complexity and costs involved.

India Hits Back Over Western Demands That it Cut its Emissions

It was bound to happen - constant harangues on several talk radio shows and on Fox television against India and China on emissions were expected to bring a tit for tat statement and here it is: http://www.telegraph.co.uk/news/worldnews/asia/india/5977599/India-attacks-British-and-Western-hypocrites-over-cutting-emissions.html As someone who lived just overlooking the Vadapalani Bus Terminus at Gowri Chitra Gardens, I have a somewhat different take on this, however. Let us not kid ourselves - India's air is filthy. And if a "better lifestyle" is what India is aspiring to, then that should include cleaner air and water. It does not make sense if Indians can buy Rolls Royces or Bentleys and if they have to breathe in filth the moment they step out of them and no longer have air filtered through carbon filters available to them. There is also the matter of health, and when I last checked, that was also a lifestyle issue - recent reports suggest that as many as 70% of Kolkata residents may have lung infections of some kind. The percentages in other cities should be similar.

While this is not going to be easy under any circumstances, I do think that India would be able to do both - work towards implementing more Renewable Energy projects (especially solar power) and advance towards a better lifestyle for Indians at the same time. Fossil fuel resources are currently held by a few nations that have been fortunate to have them located on their territory. And these are running out. Countries like India have access to abundant sunlight and they need to focus on this as a resource and develop a model that works in this context. It is not an impossible task. Some positive steps are being taken in this direction, no doubt. I wish that there would be more, and that they would be taken faster.

Let us not forget that a full 50% of all the money that India earns goes towards paying for fuel. All of this could, technically, be available for other "lifestyle" projects if it were not sent out of the country to pay for coal and crude oil.

China Throws Down a Renewable Energy Challenge to the World

While it is currently one of the world's most heavily polluted countries and it needs to import over 90% of its oil, China has decided to act in a manner that needs to be applauded: http://seekingalpha.com/article/142617-china-becomes-global-green-leader-with-massive-solar-projects?source=yahoo I am grateful to Dr Mayraj Fahim for this link showing where South Asian countries, which enjoy the same climatic conditions and suffer from similarly high pollution, are lagging seriously behind. So, for that matter, is the USA where the only action forward seems to be Barack Obama's pious talk along with the constant and stale applause of his drum-beaters in the media and in the blogosphere. While well intentioned US plans like the Pickens proposals fall by the wayside, the Chinese seem to power ahead with their desire to insulate their country from the vagaries and whims of the oil producing nations and of oil traders and their manipulations.

Yes, China has coal - so does India, but the Chinese consider their coal reserves a finite asset. India has no hesitation in preserving some of its own coal reserves while it encourages massive environmental degradation in Indonesia, Australia, South Africa and elsewhere by mining for coal there and pollutes the air and the seas by shipping it back to India. And, though India has recently articulated a massive proposal to work on solar power, it is going to be difficult for it to do much as it is way behind China on the neccessary manufacturing infrastructure to produce solar and other RE equipment.

However, this is a situation that could be a wake-up call if you ask me. There is no reason why South Asian countries - and India, Pakistan, Bangladesh, Sri Lanka etc all have excellent engineers and facilities with which to manufacture / develop renewable energy products. This could be the spark with which to ignite a powerful flame (well, yes, this is an inept simile) of Renewable Energy in South Asia. Our antions would be wealthier because of money saved, our air, water and soil cleaner, and our workers treated more humanely as they no longer have to work in near-slavish conditions in Arab countries.

Let's hope this competition is joined, and, at the soonest.
