Harnessing renewable energy is the most important aspect for a country and its economy as non-renewable energy sources such as fossil fuels are being depleted and causing environmental issues. Among the renewable resources, wind energy is abundantly available and harnessing it to produce electricity is done using Wind Turbines. The main objective of this research is to design an optimized small wind turbine (5kW) blade for residential use. This paper solely focuses on the aerodynamic aspects of the wind turbine and ideal conditions are considered for the drive train and electrical generator. AN understanding of Blade Element Momentum (BEM) theory is essential and calculations are carried out for determining the optimized design parameters. The same is calculated through PROPID and the performance characteristics is compared and validated. The design constraint was set for a 5kW wind turbine at a wind speed of 9m/s. Through the analysis of the optimized blade, it is noted that 5kW was developed at a lower wind speed of 8.1 m/s, which is a very promising outcome for regions of low wind speed.
