Most people are already familiar with what wind energy is: the kinetic energy of the wind which is constantly in motion due to local temperature variations. Under these circumstances, we can safely deduce that the Sun, which regulates these temperatures, is responsible for the energy output of the wind.
From this point, it is also evident that the role of power generators is to transform the kinetic energy to other forms, mainly electric. For a brief overview on wind power check out the following articles:

Power Generation and Measurements
As mentioned before, the kinetic energy of the wind can be easily converted to electrical energy with conventional technology. The principle and a number of formulas used to calculate the wind load, velocity and turbine efficiency are explained below.

There is a wide variety of designs as far as wind turbines are concerned. Each type however is designed to serve specific needs. For example, horizontal turbines are more stable and efficient, while vertical turbines do not need to be mounted on a tower. In general, it seems that horizontal turbines are better but special conditions, especially as far as household's are concerned, may require the use of vertical models.

Small and Large Scale Power Needs – From Wind Belts to WARP
A wind belt is a device that also converts the kinetic energy of wind to electrical energy, although it is much simpler than a wind turbine and suitable for covering smaller scale energy needs (3-50 watts). It is also much smaller in size and far more economical. On the other hand, there is the Wind Amplified Rotor Platform or WARP that can be related and compared to the wind turbines.
