2. Long tall towers with propellers on the top about 40 to 80 meters up in the air. The propellers spin around from the wind. Which turns a turbine, which creates electricity that can power many homes. The propellers on top are usually the same size or half the size of the height of the tower.

3. 4 Main Components Of Wind Turbines rotorA rotor that consists of 2 or 3 blades attached to a hub. generatorA generator that produces electricity in the form of alternating current. Control and Protection systemControl and Protection system that optimizes performance and keeps the machinery operating with safe limits. towerThe tower that raises the rotor off the ground.
