There’s a serious proposal to build an undersea electrical grid as part of the infrastructure for future offshore wind turbines. David Roberts writes about its importance:
Offshore wind power has significant advantages over the onshore variety. Uninterrupted by changes in terrain, the wind at sea blows steadier and stronger. Installing turbines far enough from shore that they’re invisible except on the very clearest days lessens the possibility of not-in-my-backyard resistance. The challenge is getting the electricity back to land, to the people who will use it…
The Atlantic Wind Connection (AWC) would provide multiple transmission hubs for future wind farms, making the waters off the mid-Atlantic coast an attractive and economical place for developers to set up turbines. The AWC’s lines could transmit as much as six gigawatts of low-carbon power from turbines back to the coast—the equivalent capacity of 10 average coal-fired power plants.
There’s a particular stretch of seabed, a flat shelf between the north Jersey and southern Virginia, that’s geologically and geographically perfect for this. That’s where they’re setting up shop. Power-hungry Google is helping foot the bill.
