Statoil builds the world's first floating wind farm off the coast of Scotland
The project - known as Hywind Scotland - cost a total of NOK 2 billion. It is expected to generate enough power for 20,000 households when it starts producing energy later this year, according to Statoil, the Norwegian state energy company behind the project. The turbines can drift in all three dimensions on the water's surface, and will be held in place by anchors on the sea bed. Long cables will carry electricity back to shore. The floating technology allows the turbines to go in deeper waters. "Some people thought we were crazy when we put a giant wind turbine on top of a floating spar structure and towed it out to sea," Statoil wrote in a press release. "But it turned out to be the future, and the future is now."
