If Solar Is Such A Good Idea, Why Doesn't It Pay For Itself?

SEE HERE The tree-hugging mindless scientifically ignorant and proud of it set have been at it again, this time in France. Stupid subsidies to encourage the solar power folks has produced huge costs and uneconomical power. Why don't people remember that if it is worth doing, someone will do it on their own? If it isn't worth doing then it shouldn't be done, not put up your tax money because some idiots think it sounds nice. I think perpetual motion sounds nice. It just suffers from the small defect of impossibility.
