what cool facts can you find about wind energy?
Wind turbines are big. A wind turbine blade can be up to 260 feet long, and a turbine tower can be over 328 feet tall — taller than the Statue of Liberty.
The United States’ wind power capacity reached more than 61 gigawatts by the end of 2013. That’s enough electricity to power nearly 16 million homes annually — more than the total number of homes in the entire state of California — and represents nearly a 20-fold increase in capacity since 2000.
