I am grateful to Dr Mayraj Fahim for this article on Alternet http://www.alternet.org/environment/136152?page=entire which describes the potential gains as well as risks that face entrepreneurs in the field of solar energy in the USA. There is one factor that the author of the article is possibly not sure off which I must mention here - rapid competition in advancing the field of solar photovoltaic power is bringing down the costs of manufacturing solar photovoltaic panels and efficiency is being pushed up every few months by new developments as companies and universities around the world take up the challenge of making solar cells more efficient and cheap. This is a fact that is known to the entrepreneurs who are involved in this industry and that is why people in Germany are happy to put their money into ventures in this field.
There is considerable movement in the field of renewable energy and if there is any disappointment, as far as I am concerned, it is in the fact that South Asia is not looking at this with the same degree of seriousness that the West is. With India, Pakistan, Bangladesh, Sri Lanka etc bathed in sunlight around the year, just imagine the potential . . . But then, I would be repeating myself like a scratched record if I go on now.
