ABSTRACT
Compared to onshore wind power, offshore wind power has a relatively short history. The first offshore wind farm was constructed in Vindeby, Denmark in 1991, with 11 turbines of total capacity of 4.95MW. By the end of 2000, there were in total 30MW offshore wind farms worldwide. In 2002, a wind farm with 80 turbines was built in the North Sea, with a generation capacity of 160MW. By the end of 2005, the world offshore wind farm capacity reached 700MW. By the end of 2007, offshore wind capacity reached 1,080 MW, taking 1.5% share of total installed capacity.
