In a deal between the Scottish government and Norwegian oil company Statoil, five wind turbines with a capacity of six megawatts each will be set on floating structures some 15 miles (25 km) off the northeast coast of Scotland near Peterhead. The Hywind pilot park, as it's named, is claimed to be the first floating wind farm in the world, and will generate enough power for 20,000 homes with operations expected to start in late 2017.
Offshore wind farms have been creating electricity off the coast of Denmark since 1991 and England, Germany and other countries on mainland Europe have followed suit, as have China, South Korea and Japan. It's a different story in the US, where until recently there were no offshore wind farms in operation or even under construction. That changed recently with the start of construction of a small wind farm off the coast of Rhode Island.
