Asked in Energy, Wind Power
How is electricity created by wind?
The most common way is for the wind to push against a Windmill, basically a large propeller mounted on a tower, which causes the propeller to spin (same principle as how an airplane propeller works, but with the wind turning the propeller, instead of the turning propeller pushing the wind). When the propeller spins, it causes a turbine generator to also spin, producing the electricity. Pretty much every kind of turbine-powered power plant (hydroelectric dam, coal-burning power plant, a nuclear reactor, or a steam engine on a ship) will work the same way, producing electricity by spinning a turbine. The main difference is how they get the energy to spin the turbine. In fact, coal, diesel (like what most ships use nowadays), and nuclear power plants all typically work by heating up water to make steam, which is then used to spin a turbine. Alternately, the wind could blow your hair around and make some static electricity to shock you with the next time you touch your hair. This method does not produce enough electricity to be useful, however.
