Denmark is Building an ‘Energy Island’

Thirty years since it pioneered offshore wind farming, Denmark is set to expand the repertoire of renewables again, this time with the world’s first “energy island.” By 2030, an artificial landmass far off the country’s western coast will channel green electricity from a vast network of wind turbines and transmit it to the mainland — enough to power 3 million homes at first, and later 10 million.
