An excellent article on story of a Solar Entrepreneur in WSJ - http://online.wsj.com/article/SB126090748287292467.html
It speaks of how the costing of solar power is difficult and the entrepreneur needs incentive (or subsidy...any way you see it is fine) from the Central Government. IMHO, just reduce the environmental hazard element from the cost and the equation will get balanced. (Yes I know it is not that simple...but then what is?)
The article is also a reflection on how much more we, as a country, have to travel to become a truly pro-entrepreneurial society.
Just one question, why use farmland for such energy generation when we have deserts and mountains that are relatively free from farming / cattle grazing needs? I am sure there is a reason, just that, I am not aware.
