Solar Today is the superb magazine of the American Solar Energy Society. They have this very interesting article about the great state of Texas and its huge investment in solar power - I hope this example would be followed by other states in the USA and also by all other countries that have sunlight for reasonable periods every year: Link
All of the nations of South Asia are excellent candidates for solar power. I hope these nations would use their heads and look at using solar power more. Yes, I do hope that this happens . . .
