Thermal solar uses water for steam generation, as does coal, natural gas, and nuclear. PV solar needs only a bit once in a while for cleaning. Wind needs none at all. Does one need more proof of what an idiot Elektra is?
Your simplistic response is indicative your lack of understanding and knowledge in which you speak, old crock.
Thermal Solar? You mean CSP old crock?
Solar PV also uses millions of gallons of water, with very little return for such a precious resource that PV squanders.
Little things Old Crock does not even fathom comes into play, like the MILLIONS OF GALLONS A WEEK, PV consumes during construction which lasts years, takes a long time to cover square miles with PV, and as stated by all you supporters of PV, we will be building PV systems forever, it will never stop.
As far as cleaning goes, who knows, its so hard to get the truth out of the Solar Companies, with all the bankruptcies and difficulties getting financed its not surprising they are tight lipped.
How much water will it take to clean a 100 square miles of PV in the dusty deserts of California? How much water to clean a 1,000 square miles of PV in the dusty desert of California, my guess is again millions of gallons.
Of course to be technical, its measured in Acre Feet.
So how much is used Old Crock, beings how you are supporting this and claiming its a little bit of water, no more.
