Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.

Large three-bladed horizontal-axis wind turbines (HAWT) with the blades upwind of the tower (i.e. blades facing the incoming wind) produce the overwhelming majority of wind power in the world today. [4] These turbines have the main rotor shaft and electrical generator at the top of a tower and must be pointed into the wind.
An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind 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.
Turbine blades for small-scale wind turbines are typically 1.5 to 3.5 metres (4 ft 11 in – 11 ft 6 in) in diameter and produce 0.5-10 kW at their optimal wind speed. [1] Most small wind turbines are horizontal-axis wind turbines , [ 2 ] but vertical axis wind turbines (VAWTs) may have benefits in maintenance and placement, although they are ...
The necessary yawing torque was created by means of animal power, human power or even wind power (implementation of an auxiliary rotor known as fantail). Vertical-axis wind turbines (VAWTs) do not need a yaw system since their vertical rotors can face the wind from any direction and only their self rotation gives the blades a clear direction of ...
