Energy 101: Wind Turbines (Video)
A form of solar energy, wind comes from the sun heating Earth's atmosphere, the rotation of the earth, and the earth's surface irregularities. Wind turbines are rotary devices that convert the kinetic energy of the wind into mechanical energy, producing clean, zero-emission electricity. This video explains the basics of how wind turbines operate to produce clean power from an abundant, renewable resource—the wind.
