“Somebody’s confusing “heat transfer” and “heat creation””
Wind turbines convert wind velocity to electric power. Energy is extracted from the wind. The turbines reduce the velocity of the wind and, I believe, cool the air slightly because the speed of the air molecules is reduced.
Adding resistance (friction) to a moving system does not create cooling. It creates heat.
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.
