One will rise off the German coast offshore wind farm large enough to power about 370,000 homes. L'offshore wind farm will count 80 wind turbines. The preliminary contract has already been signed, one of the parties involved is the Siemens who will supply the offshore wind turbines. The power plant will be that of Butendiek, in the North Sea. The construction of the Butendiek offshore plant is expected to be completed by 2015.
A few months ago, the Siemens was forced to leave the photovoltaic due to competition "unfair" Chinese. If the photovoltaic crisis did not spare Siemes, the same company did not abandon green economy in renewables and is confirmed as the leader ofoffshore wind.
The offshore wind farm largest in the world was completed in 2009. Horns Rev II, located in the North Sea and consisting of 91 turbines, again the supplier was Siemens. The power of the Horns Tev II park is around 210 megawatts, enough to meet the energy needs of around 200,000 households. With its new 80 wind turbines, Siemens will guarantee an electrical capacity of 288 Megawatts.
The wind farm of Butendiek it will be set up 34 kilometers west of the island of Sylt, near the German-Danish border. Each wind turbine has a rotor with a diameter of 120 meters and a capacity of 3.6 megawatts. L'offshore plant it will occupy an area of 42 square kilometers.
It is estimated that by 2020, wind power installed worldwide will reach 500 gigawatts. Offshore wind farms are a fast growing sector. Germany is investing a lot of resources inoffshore wind and in its waters there are 30 offshore projects, some under development and others already in operation.
