The biggest wind turbine ever installed

"Alstom has installed the world's largest offshore wind turbine off the Belgian coast, the Haliade™ 150-6MW.
This is the largest offshore wind turbine ever installed in sea waters. Thanks to its 150-metre diameter rotor (with blades stretching 73.50 metre), the turbine is more efficient since its yield is 15% better than existing offshore turbines, enabling it to supply power to the equivalent of about 5,000 households".
