Dubya and Singh have talked about giving more nuclear technology to meet increasing demands of power in India. It sounds good in the first hearing. But how good is it? Well, India is definitely gonna dig out far fewer amounts of coal and thus emit much lesser greenhouse gases. But then you have the problems of disposing the nuclear waste. On a bigger picture, I think the more you have, the more you tend to consume it. People hop in to buy more gadgets and 'utilities' with the availability of power. But more buying means more depletion and more pollution.
Vijay Vaitheeswaran of The Economist says that Centralized Power Generation is a bad idea and it should be decentralized by giving it away to markets. You'll be much more frugal when you have to generate your power in the backyard using sun, wind or whatever.
