He already wanted to hate wind then and this is just his justification. I once encountered someone telling me that wind turbines cause global warming. I told them the only part generating heat was the copper in the motor and that's the same in every power generation. Turn out Faux News misrepresented a study that showed the turbulence caused by wind turbines brought warm air to the ground level.
Damn that would be an issue if we built them in urban areas which we don't.
Except physically speaking, that warmth from the motor is still just from the energy the wind has.. energy that would get transformed to heat from friction eventually anyway. It's just that this way we get useful work for our own purposes in the form of electricity.
Regardless of the source of rotation, all other aspects are the same as far as heat generation goes. That was the point I tried getting across to the people who were insisting to me that wind turbines cause climate change. Hydro, diesel engine, NG fire or nuclear driven steam turbines, wind turbine. They're all just spinning copper coils. Any heat from those would be the same.
The copper coils also had nothing to do with the heat in question anyway. The study was just showing turbulence could bring warm air to ground level. Honestly, sounds like wind turbines should be setup above frost sensitive crops like fruit trees. One bad frost during the tree's bloom could ruin a whole year's harvest.
