Wind Energy

Wind energy is a renewable energy source that is used to generate electricity by wind power. The term, wind power, means utilization of kinetic energy of wind to generate electricity. Wind energy is termed renewable source energy because it can never be exhausted. There are other renewable energy sources, such as solar energy, geothermal energy, hydropower energy, and so on. All of them contribute to power the thermal energy stations to generate electricity.
