The air in motion is called wind. It therefore possesses energy in the form of kinetic energy. The energy obtained from wind is called wind energy. This source of energy has been in use for thousands of years and can be used for various purposes.
The benefits of wind energy are lots. Wind energy is a renewable source of energy. Energy from wind will never run out and will always be available. It does not produce greenhouse gases or other toxic elements. Areas where electricity cannot be supplied by electricity grids, wind energy is the best way to generate electricity. Wind energy is freely available. Low maintenance is required for wind energy. Because of the growth in the use of wind energy in different sectors like manufacturing and construction, several employment opportunities are being generated. It is a sustainable energy source.
Wind energy is used by wind turbines to generate electricity. Wind turbines have a few social and environmental disadvantages. It gives negative visual impact. Because wind turbines are installed at heights, their rotating blades may injure birds. They cause noise pollution. Wind turbines when installed in wind plants require a lot of land, thereby reducing the land available for other uses. They may cause interference in television signals. Wind turbines are expensive.
Most of these problems have been taken care of by using new and improved technologies to generate electricity from wind energy. Wind energy is a highly valued renewable source of energy available today.
