Energy is an important input in all sectors of any country’s economy. The standard of living of a given country can be directly related to per capita energy consumption. Energy crises are due to the two reasons; firstly the population of world has increased rapidly and secondly the standard of living of human beings has increased. To fulfill the increasing demand of energy, conventional energy source is not sufficient. That’s why now a days it is more important to fulfill the energy demand with the help of non conventional energy sources. In this paper an attempt is made to study the design and development parameters for mini wind mill used in domestic applications like generate small capacity power for buildings, households, commercials, small industry etc. effectively.
