Heron's wind-powered organ, the earliest machine powered by a windwheel [15]. Sailboats and sailing ships have been using wind power for at least 5,500 years, [citation needed] and architects have used wind-driven natural ventilation in buildings since similarly ancient times.
Offshore wind power currently has a share of about 10% of new installations. [8] Wind power is one of the lowest-cost electricity sources per unit of energy produced. In many locations, new onshore wind farms are cheaper than new coal or gas plants. [9] Regions in the higher northern and southern latitudes have the highest potential for wind ...
Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails , windmills and windpumps , but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation.
Wind Power Density (WPD) is a quantitative measure of wind energy available at any location. It is the mean annual power available per square meter of swept area of a turbine, and is calculated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density. [25]
James Blyth (4 April 1839 – 15 May 1906) was a Scottish electrical engineer and academic at Anderson's College, now the University of Strathclyde, in Glasgow.He was a pioneer in the field of electricity generation through wind power and his wind turbine, which was used to light his holiday home in Marykirk, was the world's first-known structure by which electricity was generated from wind power.
India has the fifth largest installed wind power capacity in the world. [96] As of 31 March 2014, the installed capacity of wind power was 21136.3 MW mainly spread across Tamil Nadu state (7253 MW). [97] [98] Wind power accounts nearly 8.5% of India's total installed power generation capacity, and it generates 1.6% of the country's power.
Wind power in Russia – Russia has a long history of small-scale wind power use, but the country has not yet developed large-scale commercial wind energy production. Wind power in Scotland – wind power is Scotland's fastest growing renewable energy technology, with 2,574 MW of installed capacity as of April 2011. Wind power in Serbia
There are several closely related wind turbines that use straight blades. This design of the turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer; filing for the patent was October 1, 1926. There are major difficulties in protecting the Darrieus turbine from extreme wind conditions and in making it self-starting.
