The HuffPo has a post on North America's first offshore wind farm - North America Finally Has Its First Offshore Wind Farm.
North America’s first offshore wind farm, Block Island Wind Farm, started operations last Wednesday and is expected to be in full swing by Thanksgiving. When it is running at full capacity, the farm will generate enough electricity to power 17,000 homes, or about 4 percent of all households in Rhode Island. It’s a modest U.S. launch for an industry that has been booming in Europe. But it’s a big win after 15 years of trying to get offshore wind power off the ground.
