Wind is a very powerful energy which is very essential to use properly for maximum benefits. It is associated with the movements of atmospheric air. Wind energy is a form of solar power, as wind is created by the heat of the sun. The solar radiation heats all parts of the surface of the earth but in different levels. Different surfaces of the earth, like soil, water, sand and stones absorb, reflect, retain and emit different amount of heat. However, the earth gets hotter during the daylight and gets cooler in the night time and thus, the surface of the earth gets warmer and cooler at different levels.
The air moves from one side to another and creates wind. Wind is kinetic energy and if used properly, it can be converted to useful forms of energy, for example wind turbines for making electricity, wind mills for generating mechanical power, wind pumps for pumping water or drainage, or sails to push ships and so on . Wind power is useful for any continuing energy plan, as wind power production takes a natural and virtually infinite source of power to produce electricity which is contrast to conventional power plants that rely on fossil fuels. The best thing about wind generation process is that it is clean, does not create any kind of pollution like air pollution, water pollution and soil pollution. This unique feature of wind power plant has differentiated it from some other kind of renewable energy sources, for example nuclear power that generates a vast amount of hard-to-manage waste.
However, there is one common obstacle across the world to use wind power, as creating a wind farm requires a huge tracts of land along with coastlines to capture the greatest wind movement and getting those areas for wind power production sometimes clashes with other other, like agriculture, urban development, or waterfront scene from prime location costly homes. As the requirement for clean and renewable energy is increasing, the world is now in need of the other options to limited supplies of oil, coal and natural gas. Moreover, the costs of wind power are declining continuously and with the technological advancement the wind power would become feasible as a key source of electricity and mechanical power.
Ultimately, it can be said the wind power is nature friendly and when we look at the process of its generation, we can easily understand that the source of this effective energy is unlimited. These days where shortage of resources can be seen all around, having a natural resource which can be used over and over again is really a positive sign for all of us. With a lot of advantages of using the wind energy, there is no doubt that wind mill is one of the best inventions of mankind so far. It helps mankind to fight against shortage of resources and also wipes off pollution to a large extent. Thus, this natural source of energy is beneficial for various purposes.
