Not without rereading the books. But, iirc, the windmills powered small heaters, so the action of the wind raised the ambient temperature of each windmills' surroundings. As the temperature rose, so the climate began to stabilise which in turn allowed greater changes to take place. It doesn't need to add energy to the system - the sun does that every day.
