WIND ELECTRICITY GENERATION Introduction Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back beyond the time of the ancient Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst the Babylonian emperor‚ Hammurabi‚ used windmills for an ambitious irrigation project as early as the 17th century BC. The Persians built windmills in the 7th century AD for milling and irrigation and rustic

The development of wind power in India began in the 1990s‚ and has significantly increased in the last few years. Although a relative newcomer to the wind industry compared with Denmark or the United States‚ India has the fifth largest installed wind power capacity in the world.[1] In 2009-10 India’s growth rate was highest among the other top four countries. As of 31 Jan 2013 the installed capacity of wind power in India was 18634.9[2][3] MW‚ mainly spread across Tamil Nadu (7134 MW)‚[4] Gujarat

In the article Wind Energy puffery written by H. Sterling Burnett ‚ one of the leaders of the National Center for Policy Analysis ‚ Burnett discusses wind energy is not easy to exploit or benefit as environmentalists say . Build it expensive and do not provide a reason good enough to be used . Burnett believes that the benefits are often exaggerated ‚ and its adverse effects are ignored .Burnett agreed with wind energy is not good. Burnett tells us that " wind farms‚ wind generator when only a certain

Wind energy is one of the centerpieces when looking at ways to harness renewable energy. Stabilizing climate is a growing concern‚ many are now looking at renewable energy to fix it. Wind energy is one of the centerpieces when looking at ways to harness renewable energy. Thus being said‚ wind energy is so dominating because it is abundant‚ low in cost‚ widely distributed‚ and can be developed quickly. Living in Florida‚ we are one of the top users in electricity‚ due to hot summers‚ keeping plants
