Wind is simple air in motion. It is caused by the uneven heating of the earth’s surface by the sun then the earth’s surface is made of very different types of land and water, it absorbs the sun’s heat at different rates.
Today global wind power capacity rose 27 percent in 2007 to more than 94,100 megawatts, led by capacity additions in the European Union, the United States, and China.
Brussels, 6 February 2008. The Global Wind Energy Council today confirmed its earlier estimate that over 20,000 MW of wind power was installed in 2007, led by the US, China and Spain, bringing world-wide installed capacity to 94,123 MW. This is an increase of 31% compared with the 2006 market, and represents an overall increase in global installed capacity of about 27%.

The top five countries in terms of installed capacity are Germany (22.3 GW), the US (16.8 GW), Spain (15.1 GW), India (8 GW) and China (6.1 GW). In terms of economic value, the global wind market in 2007 was worth about 25bn EUR or 36bn US$ in new generating equipment.

The market for European wind power capacity broke new records in 2006, according to the annual statistics issued by the European Wind Energy Association (EWEA) today. 7,588 MW of wind power capacity, worth some €9 billion, was installed last year in the EU, an increase of 23% compared to 2005.

Europe is leading Wind Turbine Capacity
from total of growth installed capacity of wind Europe is leading with about 75 % total installed

Installed capacity of Wind Turbine in USA
U.S. wind energy installations now exceed 10,000 megawatts (MW) in generating capacity, and produce enough electricity on a typical day to power the equivalent of over 2.5 million homes, the American Wind Energy Association (AWEA) announced today. A megawatt of wind power generates enough to serve 250 to 300 average homes.(

International ranking of Wind Turbine

The strong position of China, and even more of India (home of manufacturer Suzlon, which has just won the battle to buy German manufacturer Repower, and purchased Belgian gearbox subcontractor Hansen last year) should be noted.

The American Wind Energy Association (AWEA) reported last week record growth in wind power generation with 5,244 megawatts of capacity installed in 2007 – a 45% increasereflecting $9 billion in investment and 30% of all new power generating capacity in 2007

    Based in Kolkata an Surat “Bardhman” Air turbo is pioneer in manicuring Air ventilator. The company uses Korean Technology for this which make sure the cost is low but the quality us very high as compared to other turbine manufacturer. The turbine air ventilator manufacturer company assures you of hi quality products.
