Our countdown of the top ten things you didn't know about wind energy:
10. Human civilizations have harnessed wind power for thousands of years. Early forms of windmills used wind to crush grain or pump water. Now, modern wind turbines use the wind to create electricity. Learn how here.
9. A wind turbine has as many as 8,000 different components.
8. Wind turbines are big. A wind turbine blade can be up to 150 feet long, and a turbine tower can be over 250 feet tall, almost as tall as the Statue of Liberty.
7. Higher wind speeds mean more electricity, and wind turbines are getting taller to reach higher altitudes where it’s even windier. See the Energy Department’s wind resource maps to find average wind speeds in your state or hometown.
6. Most of the components of wind turbines installed in the United States are manufactured here. Facilities for building wind turbine parts are located in over 40 states, and the U.S. wind energy industry currently employs 75,000 people.
