We all know how important air is for our life. However today we will focus on the other beneficial part of air and that is energy that is obtained by moving air. The motion results from the heating and cooling of the Earth; thus, wind energy is an indirect form of Solar Energy.We are more in need of renewable sources of energy for our survival and what can be best other than wind energy. Wind energy is one of the oldest forms of energy used to supplement human muscle. The conversion of wind energy to various other useful forms, like electricity, is known as wind power. Wind energy is converted into these forms using wind turbines. There are wind power plants, or wind farms which are clusters of wind machines used to produce electricity. A wind farm usually has dozens of wind machines scattered over a large area.
