Abstract—Wind is the major power source to generate electricity. With the aid of moving air the intermittent source of Wind energy is dependent upon the wind speed, turbulence and wind turbine. Maximum of power produced is based upon the wind turbine resources. The wind turbine is the device that is used to charge the batteries by the conversion of kinetic energy of the moving air into the electrical power. The inefficiencies occurred in the wind turbine due to the mass of air flow through the turbine. The power delivered by the wind turbine is affected by rotor blade friction, blade drag, gearbox losses and generator. So it is necessary to increase the efficiency of the wind turbine by the changes made in the blade design and wind turbine blade design. In this review paper, the several wind turbine blade designs and the effect of blade design modifications on the efficiency of the wind tur-bine is studied.
