Cape Wind project will be big test for offshore wind energy

The newly approved Cape Wind project in Massachusetts will be closely watched, by both supporters and detractors, as it goes forward. Many see it as a barometer for the future of offshore wind energy in the US.

Power costs are a huge issue for wind projects. Offshore power is currently about twice as expensive as onshore wind generation.

But the potential of offshore wind in the US is significant. About 90,000 megawatts of power could be generated in shallow US waters alone, estimates the National Renewable Energy Laboratory. That's about triple the capacity of today's onshore generation.

The Cape Wind project could spark an offshore wind industry that will compete globally, say both Mr. Salazar and Massachusetts Gov. Deval Patrick.

"The US is 20 years behind Europe, and China is pulling ahead," says Governor Patrick. "If we get clean energy right, the whole world will be our customer."

Approving the Cape Wind project was difficult, Salazar notes, because of its proximity to important vistas, some considered sacred by local Indian tribes. Accordingly, approval required that additional archaeological research be done to ensure that native sacred areas are protected.

A letter from governors of Northeastern coastal states was a big factor in Salazar's decision. It protested a federal historic panel's recommendation that the wind farm not be approved. If the panel's advice were followed, the governors noted, most wind project proposals along the East Coast probably could not go forward.

The regulatory battle may now shift from the federal government to the courts. The Aquinnah Wampanoag tribe on Martha's Vineyard has announced that it will file suit to halt the wind farm. Others are also phoning their lawyers.

"We're absolutely taking legal action," says Patty Dineen, a spokeswoman for the Alliance to Protect Nantucket Sound, which represents many island residents.

But Salazar says he's confident that his decision – backed by nine years of environmental and other reviews – will hold up in court: "There's no question in my mind that the review has been thorough."

For environmentalists, approval of America's first offshore wind project is considered important in the fight against global warming, because it substitutes renewable wind for fossil-fuel-based energy.

"It's going to have a huge impact," says Sean Garren, a spokesman for Environment America. "Some of the best wind resources in the country are off our shores. We need to get going harnessing those clean resources."
