That is what I have always thought Robin. Even though we use some of the wind energy to generate electricity, most of that ends up as heat in one way or the other. If we use it, the heat is directly released, if the wind blows freely, friction eventually absorbs the energy which becomes heat. The end result is the same.

However the truth is that most of the energy we use is returned to the environment as heat, so taking it out as wind power and putting it back as heat would probably have very little net effect.
