The graph at left shows the growth in installed wind generation capacity in the United States based on data from the Office of Energy Efficiency and Renewable Energy. [32] In 2008, installed capacity in the U.S. increased by 50% over the prior year. The world average growth rate that year was 28.8%. [38]
The lack of ships of size needed to transport large equipment needed for wind turbines has slowed the develop of offshore wind farms. [28] [29] To comply with the Jones Act [30] [31] wind turbine installation vessels for $300 million could economically supply a schedule of 4 GW projects over 10 years. [32]
The following table lists offshore wind farm areas (by nameplate capacity) that are in various states development for the Outer Continental Shelf in U.S. territorial waters of the East Coast of the United States, [31] where a Bureau of Ocean Energy Management (BOEM) wind energy area lease has been secured [32] [33] and have gained at least some ...
The next largest wind turbines and competitors to the V164 are the Siemens Wind Power SWT-8.0-154 and Adwen AD 8-180 offshore turbines with a rated capacity of 8 MW, [16] and the prototypes of the French 12—14 MW GE Haliade and the 16 MW MingYang. [17] The Enercon E-126 turbine is rated up to 7.58 MW, but only installed onshore. [18] [7]
The study, published on Monday by a US and European research team, used data from more than 300 million home sales and 60,000 wind turbines in the US between 1997 and 2020.
In addition to the megawatt wind farms, community scale single wind turbines of from 250 kW to 750 kW are typically 50 meters high, and residential or farm wind turbines are typically 15–40 m (49–131 ft) high. To address these markets, maps are available showing wind potential at 30 m (98 ft) [7] and 50 m (160 ft). [8]
One megawatt (MW) can power about 1,000 U.S. homes but since wind is an intermittent resource - 1 MW of offshore wind can power about 500 U.S. homes, according to offshore wind developers.
Vestas V47-660kW wind turbine at American Wind Power Center in Lubbock, Texas A wind turbine blade on I-35 near Elm Mott, an increasingly common sight in Texas. Wind power has a long history in Texas. West Texas A&M University began wind energy research in 1970 and led to the formation of the Alternative Energy Institute (AEI) in 1977.
