How Wind Energy Works

Wind turbines generate electricity by using the natural power in the wind. A wind turbine's blades are like an aeroplane wing: as the air flows past the blade it causes lift, which creates a turning force. The rotating blades turn a shaft inside the nacelle, which goes into the gearbox. The gearbox increases that rotation speed for the ...
