Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity. Blade movement: The wind spins the rotor blades. They can be stand-alone, supplying just one or a very small number of homes or businesses, or they can be clustered to form part of a wind farm. Here we explain how they work and why they are. . Exponential Growth in Scale: Modern wind turbines have evolved into massive machines with offshore turbines exceeding 15 megawatts in capacity and prototype machines reaching 20+ megawatts, featuring rotor diameters approaching 800 feet that can power up to 20,000 homes each.
