Thats right, Solar is dead, non sustainable. Seems someone forgot about the lack of water in the Arizona and California desert http://ndep.nv.gov/news/temp_news/water093009.pdf I think that is sufficient to begin. All solar power plants consume water, at the very least each plant must keep the mirrors or collectors clean of dust, there is a lot of dust in the desert. The water required to clean one solar power plant is millions of gallons of water. Add the drought in California, the over use of the Colorado river, depleting the aquifers, the better use of water in agricultural food production. Solar energy is dead.
