    Oct 31, 2014 · Efficiency – When the wind blows on the blades of a HAWT, all of them contribute to energy production. When wind blows on a vertical-axis turbine, only a fraction of the blades generate torque while the other parts merely 'go along for the ride'. The result is comparably reduced efficiency in power generation.

  • How Do Wind Turbines Work? | Department of Energy

    How Do Wind Turbines Work? | Department of Energy

    Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:

    Small wind turbines - Energywise

    Wind turbines generate electricity as long as there is relatively constant wind at a reasonable speed. Most small wind turbines need an average speed of 4.5 metres per second (16 km/h). Micro and small scale wind turbines are usually mounted on towers so they're exposed to more consistent wind with a higher average speed.
