Abstract  Energy is one of the crucial inputs for social-economy and human lives. The global population is increasing day by day with the development of activities resulting in increased energy demand. The sources of energy are mainly from fossil fuels like oil, coal, etc., and also from renewable energy like wind hydro, geothermal energy etc. Wind energy is converted to electrical energy by means of wind turbines which are installed in regions where the wind speed is more and these are mounted on steel structured towers. The tower of a windmill is mainly affected by various loads acting on it, such as air forces, rotating rotor forces, blade weights, and atmospheric temperatures. Therefore the tower will soon be meeting with failure. Practically, it is impossible to check the failures of the components in running condition. Also, it is very difficult and makes a lot of losses (material, cost, time, etc.). Hence with the help of FEA SOFTWARE different materials have been analyzed and it was found that the AISI 302 stainless steel material deflection was low.

1 Introduction Generation of power other than conventional sources of energy was developed in the eighteenth century. Two great pioneers that led to the advent of windmills were Charles Brush and Poul La Cour. Charles Brush invented an efficient DC dynamo used in the public electrical grid for commercial electric lights and for an efficient method for manufacturing lead acid batteries. His company, Brush electric in Cleveland Ohio, was sold in 1889 and in 1892 it was merged with Edison General

Electric Company under the name General Electric Company (GE). During the winter of 1887–1988 Brush built what is today believed to be the first automatically operating wind turbine for electricity generation. It was a giant—the world’s largest with a rotor diameter of 17 m (50 ft) and 144 rotor blades made of cedar wood. Note that the person mowing the lawn to right of the wind turbine the turbine ran for 20 years and charged the batteries in the cellar of this mansion. Despite the size of the turbine, the generator was only a 12 kW model. This is due to fact that slowly rotating wind turbines of the American wind rose type do not have particularly high average efficiency. La Cour was one of the pioneers of modern aerodynamics and built his own wind tunnel for experiments. He was concerned with storage of energy, and used the electricity from his wind turbines for electrolysis in order to produce hydrogen for gaslight in his school. One basic drawback of this scheme was
