Wind turbines are one of the earliest devices that are used for power generation. Windmills originated from the country Persia (present-day Iran) as early as 200 B.C. In Europe they appeared during the middle ages and the first electricity generating wind turbine was installed in Scotland in July 1887. Since then new and improved ways and wind generator designs have been adopted to modify these electricity manufacturing giants to produce much more power from much less wind than ever before.
Wind farms consist of a group of several hundred individual wind turbines in the same location that are used for production of electric power on a larger scale. Today, there are more wind farms that abound Europe than any other continent in the world. The wind farms can largely be found in the plains and breezy areas in the United Kingdom. Wind power is the second largest source of renewable energy in the UK. In the year 2007 the UK Government agreed to the European Union target of generating 20% of energy from renewable sources such as wind farms and solar energy by 2020.
By the end of 2007, the United Kingdom announced plans for a massive expansion of wind energy. Presently the installed capacity of wind power in the United Kingdom is over 5 gig watts. If you have ever seen a wind farm, you will know that these are absolutely gigantic high towers having big the rotor blades that are positioned at an angle of 45 degrees so that the turbine can trap all possible energy. Therefore, even in a wind-less situations are enough to make the outer edges of the blades on a wind turbine turn around.
Turbines typically have two or three blades. The bigger the blades of the turbines the more energy they can capture from the wind. The wind turns these blades and the generator attached to it converts the generated mechanical power into electricity. Larger turbines are grouped together into wind farms, which provide bulk power to the electrical network for powering big cities and thousands of homes.
Wind farms have been providing clean and green energy unlike coal stations and nuclear power generators as they do not cause global warming or any environmental disruptions. The British Wind Energy Association is an association for wind power, wave power and tidal power industries in the United Kingdom. It has been co-ordinating the statistics and intelligence on marine and offshore wind power in the country.
