Wind Power

   Have you ever been driving through the middle of nowhere on a long road trip and seen some huge spinning fans? Those are windmills (wind turbines). Windmills harness the wind to generate electricity.

   The turbines usually have three main parts.

       1. The Stem (The pole that connects to the ground)
       2. The Rotor (The part that spins with the blades on it)
       3. The Nacelle (The gearbox with the generator inside)

   How they work: One of my sources said "A wind turbine works the opposite of a fan. Instead of using electricity to make wind, it uses wind to make electricity."  The flowing of wind makes the transmission spin to make the generator turn to make power.


   Wind is a very green source of energy and I hope that more people in the world can use it.
