The wind is produced as a result of large movements of air, driven by energy from the Sun. This means that the kinetic energy in wind is a renewable energy resource. As long as the Sun exists, the wind will too.
Wind turbines use the wind to drive turbines directly. They have huge blades mounted on a tall tower. The blades are connected to a 'nacelle', or housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator.
