Solar Power: economically and environmentally unsound

Food for thought: Solar Power: economically and environmentally unsound: http://energy.i2i.org/2011/10/24/solar-power-economically-and-environmentally-unsound/ "We still don’t know how large solar installations covering thousands of acres in the desert over long periods of time will affect the ecosystem.
To answer our earlier question, is the taxpayer “investment” in solar power worth the cost to achieve “energy independence” with “clean” power sources? It’s a trick question because solar is neither a domestic product nor a clean one.
The bottom line is that all energy sources come with some type of risk and to assume that solar panels are an economic and environmental panacea is wrong"
