Wind power is basically the conversion of the energy acquired through the wind into forms that are useful to mankind. These forms can be the production of electricity by the use of wind turbines. Wind energy currently produces just one percent of the total electricity used by the world. The electricity produced by wind power is done by converting the rotations of the turbine blades into electricity currents by way of the electrical generators.

In the older variant of producing wind power such as the windmills, the wind energy is utilized for turning mechanical machinery in doing physical work such as the pumping of water and crushing of grains. The wind farms use the wind power in large scale for the electrical grids and also, the small separate turbines that provide electric currents to the rural areas or the locations that are grid-isolated. Wind energy is renewable, available in plenty, distributed widely, clean and it helps in reducing the toxins in the atmosphere and the green house gases.

Energy:

An estimated 50 to 100 times of wind energy more than the energy of the plant biomass is present on the earth. Most of this energy is found on the higher altitudes where the wind blows at a continuous speed of over 100 miles per hour. In time, the energy of the wind is converted by way of friction into diffused heat throughout the surface of the earth and atmosphere. But the origin of the wind is a very complex perspective. The sun heats the earth in an uneven manner, which results in the poles receiving lesser energy of the sun than the equator. Additionally, the dry land involves in heating and cooling more quickly than the sea.

The power in the wind can be evoked by blowing it through wings that exercise torque on a rotating motor. The amount of the transferred power is in direct proportion to the air density, the cube of the speed of wind and the area that is swept out by the rotating motor.
