They also tend to cause high winds, notice how the wind is getting stronger as the blades turn faster!
BTW: Did you know that wind turbines are designed (and sometimes also built) buy the same people who design and build aeroplanes using the same techniques? When studying aerospace engineering in the 1980ies, designing "wind energy converters" was already part of our syllabus.
Personally, I much prefer the sight of windfarms over cooling towers and 250 metre high smokestacks of nuclear and coal fuelled powerplants. Also, I invest my (little remaining...) money in renewable engeries. I would also feel better if the aircraft I fly would be powered by biofuel or something similar.
