Week back, I reached on the blog of Vinod Khosla. I remember him because he was one of the co-founders of Sun MicroSystems but more to that he is an environmentalist. He is one of the writers who write about global warming. The practical solutions of it. This blog, speaks about what are the problems with Wind Energy over Solar Energy. Talks lot about PV Technology, Carbon Emissions and many more. If you worry about our earth, read it and more ...do on it.
