General Electric’s Haliade-X wind turbine at Rotterdam Harbor in the Netherlands. Ilvy Njiokiktjien for The New York Times G.E.’s giant machine, which can light up a small town, is stoking a renewable-energy arms race. Twirling above a strip of land at the mouth of Rotterdam’s harbor is a wind turbine so large it is difficult to photograph. The turning diameter of its rotor is longer than two American football fields end to end. Later models will be taller than any building on the mainland of Western Europe. Packed with sensors gathering data on wind speeds, electricity output and stresses on its components, the giant whirling machine in the Netherlands is a test model for a new series of giant offshore wind turbines planned by General Electric. When assembled in arrays, the wind machines have the potential to power cities, supplanting the emissions-spewing coal- or natural gas-fired plants that form […]
