Since prior to hitting the turbine blades, the individual air molecules are moving at the same speed as those around them, their is no air resistance at that point generating heat, until it hits the turbine blades.

Well if that were the case, we'd all be burning to death up here in Maine where we have a tree every square yard.

The only way they produce any heat is when we burn them.

I wasn’t trying to claim it was significant heat. But adding wind resistance is not going to provide cooling.
