Sweden's state-owned power company, a major force in European energy development, has announced two new offshore wind farms on a scale larger than the biggest known nuclear reactor. Called Vanguard and, for next year, Boreas, they will generate 1.8 Gigawatts each, compared to a single EPR of 1,600. This is approximately 10% of current UK electricity demand. They will be 47 miles off the Norfolk Coast. Who gets the power is anither matter.
