Wind farms and renewable energy: a modern version of a medieval scam

Wind farms and renewable energy: a modern version of a medieval scam – Telegraph Blogs:
"It is difficult to think of a more medieval technology than wind mills. 
They were cutting edge when Henry II was king and Richard the Lionheart was launching crusades.
 The first certain reference to a wind mill in Europe dates from 1185AD Yorkshire, apparently.
Of course, the climate was warmer back then, as even the UN's International Panel on Climate Change now accepts.
Perhaps Ed Davey might like to try to tell us that's why our medieval fore bearers went for wind."
.....Unlike solar, which, thanks to innovation, will soon be cost effective, wind farms look like they be harvesting subsidies for a generation to come.
Far from progressive, they seem to be about rent seeking.
And what could be more atavistic than that?
Through every age, a tiny parasitical elite seeks to game the system to transfer wealth from the many to the few. 

 The more I think about it, the more the renewable energy scam seems just a contemporary manifestation of this ancient, hideous idea.
