The installation required by wind power is called wind turbine. This kind of wind turbine can be roughly divided into three parts: wind wheel (including tail rudder), generator and tower cylinder. (Large wind power stations do not have a tail rudder at all, generally only small (including household) will have a tail rudder.) Wind wheel is an important part of the wind kinetic energy into mechanical energy, it is composed of a number of blades.

When the wind blows towards the blade, aerodynamic forces are generated on the blade to drive the wind wheel. Blade data request high strength, light weight, multi-purpose FRP or other composite materials (such as carbon fiber) to manufacture. (There are also some vertical wind wheels, S-type rotating blades, etc., which also play the same role as the conventional propeller blades.) Because the speed of the wind wheel is relatively low, and the size and direction of the wind often change, which makes the speed unstable.

Therefore, before driving the generator, it is necessary to attach a gear box to improve the speed to the rated speed of the generator, and then add a speed regulating mechanism to make the speed adhere to the stability, and then connect to the generator. In order to keep the wind wheel aligned with the wind direction for maximum power, a tail rudder similar to a vane is installed at the back of the wind wheel.

The iron tower is the frame supporting the wind wheel, rudder and generator. It is generally built relatively high, in order to achieve greater and more even wind, but also to have enough strength. The height of the tower depends on the influence of obstacles in the air on the wind speed and the diameter of the wind wheel. It is generally within the range of 6-20 meters.
