A windmill is a machine which converts the energy of wind into rotational energy by means of vanes called sails or blades. The first practical windmills had sails that rotated in a horizontal plane, around a vertical axis. Windmills were in widespread use across the Middle East and Central Asia, and later spread to China and India from there. The total number of wind powered mills in Europe is estimated to have been around 200,000 at its peak, compared to some 500,000 waterwheels. A windmill used to generate electricity is commonly called a wind turbine. A wind turbine consists of a rotor that has wing shaped blades attached to a hub; a nacelle that houses a drive train consisting of a gearbox, connecting shafts, support bearings, the generator, plus other machinery; a tower; and ground-mounted electrical equipment. Wind machines and traditional ‘Dutch’ windmills preceded electricity supply and were used for grinding grain. A cutting-edge technology in the field of thermoplastic composites has allowed us to create the strongest, lightest, and highest efficiency wind or water blades available in today’s market. Aerodynamics is the science and study of the physical laws of the behavior of objects in an air flow and the forces that are produced by air flows. Local mean wind speed is the most important parameter to consider in siting a windmill. Efficient windmills can produce 175 W per square meter of area swept by the propeller. The site the windmill has to be placed has to be an area with a prevailing wind of at least 15 mph. the area has to be cleared of trees and other structures that block wind. Other applications for small wind machines include water pumping, telecommunication power supply and irrigation. Capital costs for windpower are high, but running costs are low and so access to initial funds, subsidies or low interest loans are an obvious advantage when considering a wind-electric system. A large windmill (2 MW) needs an investment of 4 M € without subsidies. In wind turbines we find two basic types of generators: asynchronous and synchronous generators. The DOE/NREL scaling model is a spreadsheet-based tool that uses simple scaling relationships to project the cost of wind turbine components and subsystems for different sizes and configurations of components. The worldwide annual wind power growth was 27%. The worldwide cumulative installed capacity is now 94,000 MW. The North American market is the second largest in terms of total installed capacity and for the second year in a row, installed more wind generating capacity than any other country. India was a latecomer to the global wind energy and wind turbine industry. According to the Wind Energy Division of the National Aerospace Laboratories (NAL), nearly 40% of India's installed electricity capacity of over 120,000 MW could be generated from wind energy. The first modern wind turbine was developed in Denmark by Poul La Cour that experimented with classic windmill technology and electricity generation. In Denmark, not only the private firms but also the universities have been in the forefront of technological frontier in development of wind turbines.
