What is wind energy? Write its four applications.

The energy contained in the movement of large masses of air from one place to another is called wind energy. Its four advantages are given below: 

1. It can be used for sailing boat.
2. it can be used for generating electricity.
3. it can operated wind mill.
4. it can be used to pump out underground water. 

Wind energy is a form of solar energy. Wind energy (or wind power) describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. ... Mechanical power can also be utilized directly for specific tasks such as pumping water.Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.
