How wind generates electricity
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.
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 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. Click NEXT to learn more.
The Science of Energy Conversion1. Capturing the Wind When the wind blows, it strikes the turbine’s blades. 2. Spinning the Rotor As the wind pushes the blades, they start to rotate the rotor. 3. Increasing Rotational Speed The gearbox increases the rotational speed of the rotor to match the optimal operating speed of the generator. 4. Electricity Generation . 5. Electrical Output .
How does a wind turbine work?Wind (moving air that contains kinetic energy) blows toward the turbine's rotor blades.The rotors spin around, capturing some of the kinetic energy from the wind, and turning the central drive shaft that supports them. Although the outer edges of the rotor blades move very fast, the central axle (drive shaft) they're connected to turns quite slowly.
