Boston — The Obama administration has approved what would be the nation’s first offshore wind farm, off Cape Cod, inching the U.S. closer to harvesting an untapped domestic energy source — the steady breezes blowing along its vast coasts.
U.S. Interior Secretary Ken Salazar announced his decision Wednesday in Boston, clearing the way for a 130-turbine wind farm in Nantucket Sound. Cape Wind was in its ninth year of federal review, and Salazar stepped in early this year to bring what he called much-needed resolution to the bitterly contested proposal.
Approval of the project would break new ground in the drive toward renewable power, Massachusetts Energy and Environmental Affairs Secretary Ian Bowles said.
“This will be the shot heard around the world for clean energy,” he said.
Cape Wind officials said the project can generate power by 2012 and aims to eventually supply three-quarters of the power on Cape Cod, which has about 225,000 residents. The officials said the project will provide green jobs and a reliable domestic energy source, while offshore wind advocates want it to jump-start the U.S. industry.
Major U.S. proposals include a project in Texas state waters, but most are concentrated along the East Coast north of Maryland, including projects in Delaware and New Jersey.
Massachusetts Gov. Deval Patrick has been an enthusiastic backer of Cape Wind, pushing it as key to the state’s efforts to increase its use of renewable energy.
But Cape Wind met with heavy resistance from people who wanted it moved out of the sound, and its opponents are expected to continue to try to derail the project in court.
Critics said the project endangers wildlife and air and sea traffic, while marring historic vistas. The late U.S. Sen. Edward Kennedy fought Cape Wind, calling it a special interest giveaway. The wind farm would be visible from the Kennedy family compound in Hyannisport.
Democrat U.S. Rep. William Delahunt, who represents Cape Cod, said allowing the project to move forward will open “a new chapter of legal battles and potential setbacks” for the wind power industry.
“Cape Wind is the first offshore wind farm to be built in the wrong place, in the wrong way, stimulating the wrong economies,” Delahunt said Wednesday.
The project is about five miles off Cape Cod at its closest proximity to land and 14 miles off Nantucket at the greatest distance. According to visual simulations done for Cape Wind, on a clear day the turbines would be about a half-inch tall on the horizon at the nearest point and appear as specks from Nantucket.
Opponents also said the power from the pricey Cape Wind project, estimated to cost at least $2 billion, would be too expensive.
U.S. Sen. Scott Brown of Massachusetts, a Republican, said the project will jeopardize tourism and affect aviation safety and the rights of the Native American tribes.
Cape Wind appeared close to final approval in January 2009 when the lead federal agency reviewing the project, the Minerals Management Service, issued a report saying the project posed no major environmental problems.
But two Wampanoag Indian tribes claimed the project would ruin a sacred ritual that requires an unblocked view of the sunrise over the sound, and would be built on long-submerged tribal burial grounds.
Early this month, a federal historic council backed tribal claims and recommended Salazar reject the project, citing its “destructive” effects on views from dozens of historic sites.
