Roger, does this only apply to wind farms in the south?

Ryan-------I think the source of Rogers view of wind farms is flawed act of the blowing wind is turning the blades, not the blades turning and causing the wind to blow----------


My thoughts are because you don't creat or destroy energy with normal means so there fore I assume that after the wind has lost its energy to the turbine fans, there will be less energy in the air so it will be cooler-------also when the wind blows by the rotating fan blades, it hardly gets disturbed so very little if any turbulence is created-------

You guys have left out a portion of the calculus...............all the additional heat generated by the rotting bird carcases on the ground near the machines.

I thought the cooling action of the blades compensated for the heat decay?

But what really worries me, is the addition speed added to the earths rotations caused by these machines and how much older it is making us. Explains why I'm losing energy..

Would someone just please call Al Gore and find out the true skinny?

I sent him a letter on this, but I forgot to put a stamp on the envelope..........

Roger, we shouldn't forget that in converting the kinetic energy of the wind to electrical energy, those turbines generate some heat. After all, they aren't friction-free.
