The world's first floating wind farm started generating energy today -- here's how it was constructed

The world’s first floating offshore wind farm started producing electricity off the Scottish coast on Wednesday.

Hywind Scotland, as the project is known, consists of five huge linked wind turbines which float over deep ocean water while loosely tethered to the seafloor.

They were constructed on land in Norway, and dragged across the North Sea earlier this summer before being moored off the Aberdeenshire coast.

The wind farm is expected to generate enough power for 20,000 households at full capacity according to Statoil, the Norwegian state energy company behind the project.
