Not going to further hijack Em's oil thread after this reply, but you'll find that the ambient temp in the immediate area of a wind farm rises about 1C over a decade (all but irrelevant). Those turbine blades are being driven by the wind's kinetic energy and don't add velocity. The effect to ambient is due to increased turbulence, mixing the air from ground level up a couple of hundred feet, much like the fans in orchards and vineyards used to prevent frost damage. Instead of the normal cooling of the earths surface as the sun goes down (radiant loss to the night sky) the mixing negates a little bit of the drop. Now back to the regularly scheduled programming....
