Open Ocean Wind Farms in North Atlantic Could Power the World

Anna Possner and Ken Caldeira have published their findings in Proceedings of the National Academy of Sciences . Wind turbines in the open ocean could in theory intercept more than five times as much energy as wind turbines over land. This presents an enticing opportunity for generating renewable energy through offshore wind turbines. But it was unknown whether the faster ocean winds could actually be converted to increased amounts of electricity. “Are the winds so fast just because there is nothing out there to slow them down? Will sticking giant wind farms out there just slow down the winds so much that it is no better than over land?” Caldeira asked. Most of the energy captured by large wind farms originates higher up in the atmosphere and is transported down to the surface where the turbines extract this energy. Other studies have estimated there is a maximum rate of e...
