Wind Energy: A Natural Source
Nature is the ultimate source of energy. Everything we use in the name of energy comes from nature and its resources. Wind is an energy converted form of solar energy. This kinetic energy is linked with the changing moves of atmospheric air. For hundreds of years, wind energy has been used for various purposes, such as sailing, grinding grain and for irrigation. Wind energy systems have the capacity to translate this kinetic energy to more effective power forms. The rays of sun touch different parts of the earth at different levels during the day and night. Therefore, the different surfaces, such as water and land, absorb or reflect heat at different levels and at different time. As a result of which, different portions of the earth get warmed differently. By reducing the atmospheric pressure at the earth’s surface hot air increases and cool air is drawn in to replace it and thus, wind is created. (more…)
