A Dutch energy network has proposed radical plans to build an island that will act as a hub for vast offshore wind farms that would eclipse today’s facilities in scale. The power hub would be built off the East Yorkshire coast, and would send electricity over a long-distance cable to the UK and the Netherlands, and possibly later to Belgium, Germany, and Denmark. The sci-fi-sounding proposal is sold as an innovative answer to the industry’s challenge of continuing to make offshore wind cheaper.
