Wind carries enormous quantity of energy. Wind energy is mainly used to generate electricity. Wind is called a renewable energy source because the wind will blow as long as the sun shines. Wind energy is plentiful, renewable, widely distributed, clean, and reduces greenhouse gas emissions when it displaces fossil-fuel-derived electricity. When wind strikes an object, it exerts a force in an attempt to move it out of the way. Some of the winds’ energy is transferred to the object, in this case the windmill, causing it to move.
Wind turbines convert the kinetic energy in the form of mechanical energy The wind turbine works opposite to the fan Wind turbines use wind to make. The wind turns the blade, which spin the shaft which connect to the generator and makes electricity.

A ministry of non-conventional energy resources was established in India. Due to effort of govt. of India today we rank fourth in the World with regard to the total wind power installation after Germany, Denmark and U.S.A. It is estimated that global wind power capacity Is 74 GW an India has 20,000 MW out of the gross capacity of 45,000 MW
Wind turbines operate on a simple principle: The energy in the wind turns the propeller-like blades around a rotor. The pitch of the blades makes optimum use of the wind direction. The rotor is connected to the main drive shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy. At 30 metres or more above ground, they can take advantage of faster and less turbulent wind. Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electricity grid for more widespread electricity distribution.
The installed wind power generator capacity up to sept. 2006 was 6018 MW out of which 1080 MW was installed in the year 2006 itself India is growing at rapid rate
The Wind blows day and night, which allows windmills to produce electricity throughout the day. Wind power is very low cost (after the initial production and installation) Wind power is clean and renewable and sustainable resource. Wind energy is a domestic, renewable source of energy that generates no pollution and has little environmental impact.

80% Depreciation in the first year. Operation and maintenance costs are low. Zero input fuel cost. Pay back in shorter duration. Cost of generation is almost zero after pay back period. Zero import duty on certain parts. Tax holidays for newer power projects for 5 years. Wheeling to SEB is easy, so no marketing problems
We conclude that the wind power generation in India has a bright future since generation rate is increasing almost at 25% to 30% in the last decade it is further likely to be accelerated and by year 2012 we may be able achieve almost 50% of India’s potential of wind energy generation.
