The uneven heating of the earth’s surface causes winds to blow. The earth gets heated in different manner because of the difference in the surface temperatures at various places. The air above the surfaces that get more heated heats up and gets warm. The warm air that is lighter rises up creating a low pressure at the area left vacant. The cooler air from surrounding areas then rushes in to take the place of the warm air and this movement of air is called wind.
Wind possesses kinetic energy which is called wind energy. The sun indirectly provides wind energy and so this is a renewable energy source. Wind energy will be available for as long as the sun shines.
Wind energy is also a clean and green renewable energy source. It neither causes pollution nor does it emit harmful substances that might be hazardous for the health. As a green renewable energy source, wind energy also does not contribute to global warming in any way and prevents the degradation of the environment.
Wind energy companies use wind energy by harnessing it by using wind turbines to produce electricity. This electricity can be used for both domestic and commercial purposes. The development of technology has resulted in wind energy being used as an alternative energy source for the generation of electricity.
Renewable wind energy can produce enough electricity that can meet the power and energy demands of a whole nation. Technologies must be developed that can further promote the use of wind energy as an alternative energy source.
