Here's my theory: the fans are slowing down the breeze, which would otherwise cool things off, sort of like driving around in your pickup with the windows up.
Since it's hot as hell there anyway, why not build more windmills--enough to generate heat enough to boil water and spin turbines.
Think about it: if too much of a good thing is bad, then maybe too much of a bad thing is really good. I should remember this next time my wife....
In West-Central Texas, a significant part of the time is spent with the air temperature hotter than the ground temp.
Have you ever felt 100°F wind?
