The world's biggest offshore wind turbine dwarfs the tug boat towing it, Sunday, August 20, 2006, to Talisman Energy's Beatrice wind farm demonstration project 25 kilometres off the east coast of Scotland. The 87-metre high structure is one of two turbines that will each generate about five megawatts of electricity and test the feasibility of a 200-turbine offshore wind farm that could provide about 20 percent of Scotland's electricity.
