How Do Wind Turbines Work To Generate Electricity – Animation
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.

Working of a wind turbine is illustrated in this video with the help of animation. The topic covered are blade design, use of brake, velocity sensor, yawing mechanism, blade tilting, wind turbine efficiency and Betz’s limit. Watch the video from Learn Engineering for more info:
Determines the design of the turbine. Upwind turbines—like the one shown here—face into the wind while downwind turbines face away.Lifts and rotates when wind is blown over them, causing the rotor to spin. Most turbines have either two or three blades.Blades and hub together form the rotor.Turns the low-speed shaft at about 30-60 rpm.

Connects the low-speed shaft to the high-speed shaft and increases the rotational speeds from about 30-60 rotations per minute (rpm), to about 1,000-1,800 rpm; this is the rotational speed required by most generators to produce electricity.Produces 60-cycle AC electricity; it is usually an off-the-shelf induction generator. read more: energy.gov
