The Aerogenerator X turbine differs from conventional wind turbines in that it is a vertical axis type and not a horizontal axis one. This reduces the weight over a conventional design with the same capacity by about half. The weight is one of the biggest problems when larger wind turbines are being developed.
The blade travelled more than 6,400 km through ten states gathering signatures from Americans who support green energy.
Within the EU, it takes an average of 42 months to get approval for a wind farm – the time needed to apply for an onshore project ranges from less than 10 to over 50 months. These are the results of the project "Wind Barriers", which was coordinated by the European Wind Energy Association (EWEA).
Under the lead management of the Spanish energy company Acciona Energy, a consortium of 17 companies, universities and technology centres will work on the integration of various marine energy sources on a single deepwater platform.
A total of 338 turbines – stretching across 30 square miles – are to be installed in 2011 and 2012. Additionally, Caithness Energy plans to build 85 miles of road and 90 miles of power connection to the grid. Construction of the wind farm starts this year und will be completed in 2012.
The first offshore wind farm with a capacity of up to 600 MW will be built off Changhua county on Taiwan's west coast. The turbines will be erected 2.5 to 10 km off the coast at water depths of up to 30 m. In the future, SeaEnergy Renewables Ltd. (SERL), based in the Scottish city of Aberdeen, and TGC want to cooperate in planning, constructing and operating offshore wind farms in Taiwan.
On 14th September, GE concluded the takeover of the Norwegian Scanwind Group AS. The company headquartered in Trondheim currently employs a staff of 41 and specializes in developing and producing offshore wind turbines without a gearbox. In March 2003, Scanwind erected a 3 MW prototype with a permanent-field generator, a second one followed in the autumn of 2004.
The first five turbines will be delivered in the fourth quarter of this year for the project Brunsmo at the Karlskrona site. All the turbines will be produced at the GE factory in the German town of Salzbergen. According to GE, the 2.5xl is designed for use in areas where weak winds prevail and is thus well-suited to the forested region in South Sweden.
The construction of the 28,000 m2 production plant in Hutchinson is set to start in August. According to Siemens, the first nacelle made in Kansas will leave the factory in December 2010. All the nacelles manufactured in Kansas will be used for the 2.3 MW turbines from Siemens. A production capacity of 650 units per year in planned.
Enbridge began construction in July of 2007 and the wind farm began supplying energy to the province's electricity grid in August 2008. The final turbine came online in mid-February 2009. When operating at peak capacity, the 115 turbines can provide enough electricity to power between 50,000 and 60,000 homes.
