Wind is just moving air. It has huge amount of stored energy, which is called kinetic energy.
This energy is harnessed by windmills to produce power. Windmills have large blades that move when the wind blows. The blades have special curved shape, so that they capture as much energy from the wind as possible.
When the wind turns the blades of windmill, it spins a turbine inside a small generator to produce electricity. A single windmill on a farm can make only a small amount of electricity, enough to power a few farm machines.
To make enough electricity to serve lots of people , power companies build 'wind farms' with dozens of windmills.
Wind farms are built in flat, open areas where the wind blows at least 22.2 kilometers per hour. Windmills can be seen in Indian states like Tamil Nadu and Rajasthan, where the winds are strong and constant.
