Horizontal axis windmills have the rotor shaft and electric generator at the top of the tower, and it is pointed in or out of the wind. Smaller turbines are indicated by a simple wind vane, while larger turbines use wind sensors coupled with an auxiliary motor.

When carefully placed alongside wind and solar generation and operated with intelligent scheduling, they can absorb renewable energy when it is abundant, reduce peak strain on feeders, and support grid stability in the right market conditions.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
