Learn how wind turbines use wind to make electricity, and explore the types, applications, and benefits of wind energy. Watch a video, see a wind turbine animation, and find more resources on wind power. A wind turbine is a device that converts the kinetic energy of the wind into mechanical power. This mechanical power can then be used to generate electricity. Learn all about wind turbines: find key information about how they work, their parts, and the 4 different existing types. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels.
