Air is an important natural resource. In order to utilize air as a good resource we have to control the Air Pollution, which is due to industry, thermal power stations, automobiles, and domestic combustion etc. There are always additions of a number of harmful gases to atmosphere. These adversely affect air quality and make it unfit for living organisms.

Moving air is known as wind which produces energy. Like solar energy, wind energy is a very important non-conventional source of energy. In India, the wind power is of great significance as there are large coastal, hill, and desert where wind energy can be carefully exploited for generation of electricity and water pumping. Wind energy may be converted into mechanical and electrical energies. Wind energy in India is generally utilized in wind pumps, wind battery charges, wind electricity generators etc.

By the development of technology, wind power may become most economical and environmental friendly source of electricity in many countries in the coming 10 to 20 years.

The future for wind energy is many more and bigger horizontal axis wind turbines (HAWT) with much higher capacity factors and much lower cost per MWH. Wind will overtake nuclear shortly and cause many more coal plants to shutter in the next decade and gas generation in the following decade. Nations will continue to shift investment to wind from nuclear and gas generation.
