Abstract—Wind energy represents a viable alternative, as it is a virtually endless resource. Through the next several decades, renewable energy technologies, thanks to their continually improving performance and cost, and growing recognition of their Environmental, economic and social values, will grow increasingly competitive with Traditional energy technologies, so that by the middle of the 21st century, renewable Energy, in its various forms, should be supplying half of the world’s energy needs. In this paper various types of wind turbine are reviewed to understand and the development and modification of horizontal axis wind turbine and how more power can be generated compared to bare turbine of the same rotor blade diameter.

Index Terms—Wind jet turbine, Diffuser adjustment wind turbine
