How a Wind Turbine works

Wind turbines work on a very simple principle: the wind turns the blades, which causes the axis to rotate, which is attached to a generator, which produces DC electricity, which is then converted to AC via an inverter that can then be passed on to power your home. The stronger the wind, the more electricity is generated from the motion.

Thinking backwards. You might have noticed that wind turbines look just like giant propellers—and that''s another way to think of turbines: as propellers working in reverse. In an airplane, the engine turns the propeller at high speed, the propeller creates a backward-moving draft of air, and that''s what pushes—propels—the plane forward.With a propeller, the moving
