On Thursday, Sept. 17 Denmark's Crown Prince Frederik, turned on a switch to start 91 wind turbines 19 miles (30 kilometers) off the west coast of Jutland in the North Sea, which will generate enough electricity for 200,000 Danish households. The turbines are operated by DONG Energy - the photo above shows CEO Anders Eldrup speaking at the official opening ceremony.
Denmark's launch of the world's biggest offshore wind farm comes just before the global climate conference in the capital, Copenhagen, December 7-19. At this conference world leaders will try to hammer out a new global climate treaty to replace the Kyoto Protocol that expires in 2012.
Denmark, which gets a fifth of its electricity production from wind, aims for an ambitious treaty in Copenhagen and hopes the conference will boost its environmental technology industry.
The 3.5 billion crowns ($694 million) wind park overtakes another Denmark installation, the 166-MW Nysted wind farm - also DONG Energy's - as the world's biggest offshore wind park.
