Abstract
Renewable energy technologies are receiving much attention to replacing power plants operated by fossil and nuclear fuels. Of all the renewable technologies, wind power has been successfully implemented in several countries. There are several parameters in the aerodynamic characteristics and design of the horizontal wind turbine. This paper highlights the key sensitive parameters that affect the aerodynamic performance of the horizontal wind turbine, such as environmental conditions, blade shape, airfoil configuration and tip speed ratio. Different turbulence models applied to predict the flow around the horizontal wind turbine using Computational Fluid Dynamics modeling are reviewed. Finally, the challenges and concluding remarks for future research directions in wind turbine design are discussed.

Summary
Energy demands are increasing as the world’s population and industrial growth continue to expand [1]. The world’s consumption of energy is predicted to increase by 56% from 524 quadrillion BTUs in 2010 to 820 quadrillion BTUs in 2040 [2]. The extensive consumption of fossil fuels is the primary source of carbon dioxide emissions in the atmosphere. The CO2 released from fossil fuel burning is estimated to increase from 1,000 million metric tons in 2010 to 36,000 million metric tons in 2020 and may reach 45 billion metric tons by the end of 2040 [3]
