Wind Farms
A wind farm is a group of wind turbines in the same location used for production of electricity. A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may also be located offshore.
Almost all large wind turbines have the same design — a horizontal axis wind turbine having an upwind rotor with three blades, attached to a nacelle on top of a tall tubular tower. In a wind farm, individual turbines are interconnected with a medium voltage (often 34.5 kV), power collection system and communications network. At a substation, this medium-voltage electric current is increased in voltage with a transformer for connection to the high voltage electric power transmission system.
Many of the largest operational onshore wind farms are located in the US. As of 2012, the Alta Wind Energy Center is the largest onshore wind farm in the world at 1020 MW, followed by the Roscoe Wind Farm (781.5 MW). As of November 2010, the Thanet Wind Farm in the UK is the largest offshore wind farm in the world at 300 MW, followed by Horns Rev II (209 MW) in Denmark.
There are many large wind farms under construction including; The London Array (offshore) (1000 MW), BARD Offshore 1 (400 MW), Sheringham Shoal Offshore Wind Farm (317 MW), Lincs Wind Farm (offshore), (270 MW)Shepherds Flat Wind Farm (845 MW), Clyde Wind Farm (548 MW), Greater Gabbard wind farm (500 MW), Macarthur Wind Farm (420 MW), Shepherds Flat Wind Farm (845 MW), Lower Snake River Wind Project (343 MW) and Walney Wind Farm (367 MW).

Famous quotes containing the words wind and/or farms:
“Have you not a moist eye, a dry hand, a yellow cheek, a white
beard, a decreasing leg, an increasing belly? Is not your
voice broken, your wind short, your chin double, your wit
single, and every part about you blasted with antiquity? and
will you yet call yourself young?”
—William Shakespeare (1564–1616)
“Look. And the dancers move
On the departed, snow bushed green, wanton in moon light
As a dust of pigeons. Exulting, the grave hooved
Horses, centaur dead, turn and tread the drenched white
Paddocks in the farms of birds. The dead oak walks for love.”
—Dylan Thomas (1914–1953)
