China Opens World's First Wind-Powered Underwater Data Center

China has put the world's first offshore wind-powered underwater data center into full operation off the coast of Shanghai's Lingang Special Area. Built by Shanghai Hailanyun Technology, known as HiCloud, the submerged site runs at a capacity of 24 megawatts, houses close to 2,000 servers, and draws about 95 percent of its electricity from a nearby offshore wind farm. Surrounding seawater cools the racks passively, removing most of the power that land-based centers spend on air conditioning.
