In which the high generation level of renewable resources gives new opportunities and challenges for power sector (Alhelou et al., 2015 Alhelou & Golshan, 2016). Generation of power from renewable energy resources has been extensively increased in several countries due to environmental issues and fossil energy trouble. A single 750 KW wind turbine produces roughly 2 million kilowatt hours of electricity annually (James, 2009). This is due to new or expanded coal plants. The US Department of energy also projects that CO 2 emissions from power generation will increase by 19 percent between 20. Coal-fired plants alone released over1.9 billion tons, which is one-third of the US total. This accounted for 39.5 percent of the total emissions from human resources, according to the US Department of Energy. Electricity consumption accounted for more than 2.3 billion tons of CO 2 in 2006. In the United State (US) average fuel mix about 1.5 pounds of CO 2 are emitted for every kilowatt-hour that is generated. Reducing carbon dioxide emissions is a major contributing factor in alternative energy proposals. The analysis results show that a blade angle of 10º gives the best possible power and pressure and velocity distributions are plotted for every case. In this article is considered the single airfoil National Advisory Committee for Aeronautics (NACA) 0018 and a computational fluid dynamics (CFD) analysis is done at different blade angles 0º, 10º, 15º, and 30º with a wind velocity of 4 m/s. The turbine blade is the most important component of any wind turbine. A wind turbine transforms the kinetic energy in the wind to mechanical energy in a shaft and finally into electrical energy in a generator. Wind energy is the major alternative of conventional energy resources. Wind energy is relatively labour intensive and thus creates many jobs. Electricity produced by the wind produces no CO2 emissions and therefore does not contribute to the greenhouse effect. AbstractThe country or region where energy production is based on imported coal or oil will become more self-sufficient by using alternatives such as wind power. ![]()
