The blowing wind possesses kinetic energy which can be converted to several useful forms of energy that can be put to use for many purposes. This kinetic energy needs to be harnessed so that renewable wind energyy can be put to use in different applications. Renewable wind energy can be harnessed by using machines called wind turbines.
A wind turbine has two or three propeller like blades which are called rotors. These blades or rotors are attached to the top of a very tall tower. When the wind blows, the rotors spin and power a generator. The generator has a large number of copper connectors and magnets that produce electricity. This electricity can be used as an alternative power source to meet the power needs of urban and rural areas.
Rotors are installed at a height so that they can capture the maximum renewable wind energy whose intensity is more at high altitudes. This also ensures maximum power generation. The electricity generated by a wind turbine can be used as an alternative power source to meet the power requirements of a single household or a small community and can also be used to power mills for grinding grains and to pump water. However, the electricity produced by a wind turbine is not enough for commercial purposes. Therefore, wind farms need to be installed with a large number of wind turbines. Together, this large number of wind turbines generate enormous amount of electricity that is supplied to electricity provider companies that provide electricity for commercial use.
