Wind power has been used as energy since ages. A lot of interest has been shown in wind energy for power production. Power in the wind is proportional to the cube of the wind speed. Wind energy may be utilized for various purposes like water pumping and power generation. It has been considered to be potentially available, practically application and economically viable as a non-conventional source of energy.
In India its potentially has been estimated to be at least 20,000 MW. Till the end of the eighth five year plan wind farms of total capacity of 900 MW have already been installed and connected with grid. To support wind energy programs wind resources estimation program is being implemented. Financial assistance is being provided through IREDA to the manufactures of wind machines as well as well as to those who are installed wind farms in the country. Decision to established wind research center has also been taken with the help of Danish government.
