Wind energy is a well-known renewable energy source, accounting for 6% of worldwide power generation. This paper presents a comprehensive discussion of wind turbine blade design and explains how today's wind turbines almost never employ horizontal axis rotors. The concepts of modern wind turbine blade aerodynamics design are explored in depth, including blade shape/number of planes, blade selection, and optimal angle of attack. This paper discusses the fundamental concepts of design parameter selection and multi-aerodynamic configurations in the aerodynamic design of a horizontal axis wind turbine (HAWT) producing system. Based on a comparison of Wilson and Schmitz wind turbine aerodynamic design methodologies, the best design approach HAWT based on Schmitz is given. The basic understanding about wind turbines is summarised in this document, which also includes a comprehensive overview of the wind energy system and a discussion of wind energy's environmental implications.
