There is no denying that non-conventional energy resources need to be employed for solving energy problems. And although these technologies may seem more expensive compared to coal fired plants, a large scale investment would bring down costs as well as enhance technology.
However, I disagree with the view that decentralized energy generation is the only way to go ahead. The government has to invest in large scale energy programs based on conventional, nuclear and hydro power. Decentralization makes sense for scarcely populated areas, but for large cities, mainstream investment is quite necessary!
