How a Wind Turbine Works Posted: November 16, 2005
Wind is a form of solar power. As the earth rotates and the sun heats the atmosphere, the hot air rises above cooler air, creating a current. The wind turns the blades of a turbine, which spins an internal shaft connected to a generator and makes mechanical power or electricity used to power homes and other purposes.
