Vertical-axis wind turbine - Wikipedia

A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes ...

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:

How it works? - Vortex Wind Turbine in a Nutshell

The disturbance of the downstream wind current is why regular turbines need to be installed far from each other. This doesn't affect bladeless wind turbines, any limitation associated with the "wake effect" is avoided. Furthermore, we expect Vortex devices to work better together, feedbacking each other if they have the proper free space around them, which is estimated to be half of the ...

How a Wind Turbine Works - Text Version | Department of Energy

Turbine blades vary in size, but a typical modern land-based wind turbine has blades of over 170 feet (52 meters). The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field. When wind flows across the blade, the air pressure on one side of the blade decreases.
