The first German offshore wind facility is expected be put into operation sometime in 2009. A total of 12 giant wind turbines out at the North Sea will turn near the isle of Borkum, each one generating 5 megawatts of power, the largest worldwide. The electrical current they will produce will be conveyed over a distance of 45 km past Norderney to the mainland, at a depth of two to three meters buried in the seafloor.
