The plan involves building Scotland’s tallest building—a giant cable factory—and a special ship to lay the lines. Since coal and gas plants can sit near the areas they serve, their transmission lines generally don’t need to travel long distances. Already, grids in Northern Europe are being connected by subsea cables to share growing supplies of wind power. A 475-mile power line from the U.K. to Denmark, the world’s longest land-and-subsea grid connection, was switched on in December. A 550-mile line will bring wind power to California and Arizona from New Mexico.
