Wind energy is an indirect type of solar energy, from between 1-2% of the solar radiation that reaches the earth is converted into wind energy, and as a result of the differences in atmospheric pressure, the wind moves rapidly from areas of high pressure to areas of low pressure, so it is clear that wind energy is one of the most important types of renewable energy sources by using vertical axis wind turbine and horizontal axis wind turbine. In this study, the rotor vertical axis wind turbine was designed based on the available data obtained from the Meteorological Center of Nalut Libya. In addition, the performance of the rotor vertical axis wind turbine was predicted using the momentum and blade element theory, and the final results show that the annual energy amounts and the power factor of the selected site positively affect the performance of the designed rotor turbine
