Abstract: Wind energy is the most available form of renewable energy among all the energy sources. Wind energy can be extracted by a wind turbine and can be converted into electrical energy using proper electricity generating apparatus. This paper is focused on a technique that can be used effectively for the purpose of converting the kinetic energy of wind into electrical energy. This process is completely friendly to environment and the cost associated with the fabrication is very little. In this research a vertical axis wind turbine has been designed and fabricated to perform the job of extracting energy from wind. The turbine is of Darrieus type with three twisted blades. For the conversion of mechanical energy from the turbine into electric current an alternator also fabricated and coupled with the turbine. This paper describes the whole procedure to build up a simple wind power system with vertical axis wind turbine and shows performance of such power system under various wind speed. The specialty of this system is its extremely simple arrangement and absence of any motion transmission
