Wind Energy: Another Green Energy
Friday, December 29th, 2006When the earth came into being the wind also came to serve the life. The poets have enjoyed the romance in flowing winds, the soothing aroma that flower transferred through wind(breeze) making environment so charming that energized the human spirits to love and care for mutual co existence. Wind Energy as solution to the energy has been in use since ancient times.
There is a wonderful citing to be read ,“The first windmills for grinding grain appeared in Persia more than 1,000 years ago, and later spread as far as China and northern Europe, where the Dutch developed the massive machines for which the country is still known.”[1]
Therefore, the Wind Energy can be referred as Ancient Technology for Modern Times. Lets us see how Wind Energy works. The Sun when heats the environment the air begins to heat up and rises, which is cold air enters the vacuum created by this and flow of air or air currents are created(since the earth is heated differentially i.e. more at equator less at poles). This flow of air is Wind Energy, which is passed though large fan sort structure with the specially curved large fan blades mounted on rotating shaft, to which is connected the electricity generator. These large fan structures are known as Wind Energy towers. They have varied shapes, sizes according to the ecosystem and wind convection currents available. The Wind Energy turbines are sited after detail study and careful monitoring of air currents. The practical rule for this is the wind blowing regions must have wind velocity of 10mph (17kmph).
