Windmills are generally used to harness power of wind to perform mechanical work as well as generation of electricity. Applications of windmills are as follows –

• Large Scale Electric Power Generation- Huge numbers of windmills are installed on a single site called as wind farms to produce large scale electric power from wind.Small Scale Electric Power Generation- Single windmill can be installed in remote locations to produce electricity, where connection to the general electric network is not available
• .Pumping Water for Irrigation- Windmill is used for pumping of water from the well for agricultural purposes.
• Milling Grain- Windmills are used to grind grain, cut wood and supply water in some locations where electricity is not available.
• Windmills in Warfare- Initially, windmills were used as watchtowers because they were constructed on the tops of hills or mountains.
• The energy produced by windmill does not generate any pollution, which is an infinite source of energy.
• As windmill generates energy from wind it does not require fuel.
• It does not create greenhouse gases.
• It does not produce toxic or radioactive waste.
• It is also used for driving all sorts of mechanical devices for manufacturing.
• Windmill is generally used to convert wind energy into rotational energy with the help of blades.
• Windmills provide energy to windpumps, hammermills, saw mills and paper mills for obtaining fresh water from underground.
• In current scenario windmill technology is at its best and the wind turbines promises to be a vital alternative to fossil fuel.
• Energy produce by windmill is cheap.
• It is a renewable energy source.
• When wind energy is produced it does not create any ill effect on environment.
• Wind power is the cheapest source of energy that is available in current arena.
• The operating cost of windmill is very low.
• Wind energy provides jobs in production, maintenance, research and installations of windmills, as windmills are becoming popular.
• Windmills produce electricity at 5 cents kilowatt per hour.
• Current windmills with 2 or 3 thin blades connected to a long pole type base add a more modern aesthetic to land.
