How wind turbines work. Wind turbines use blades to collect the wind''s kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.

It''s a fairly simple process: When the wind blows the turbine''s blades spin, capturing energy – this energy is then sent through a gearbox to a generator, which converts it into electricity for the grid with a special device called an inverter. "One of the main benefits of wind power is that it moves our turbines without us having to pay

Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.
