Wind power to aid energy crunch
Atlantic states look to offshore wind turbines for energy.
WASHINGTON (AP) — Visitors to Rehoboth Beach, Del., soon may be greeted by more than sand dunes, seagulls and beach umbrellas. If offshore wind advocates have their way, scores of 140-foot blades will be spinning in the ocean breeze nearly a dozen miles away, barely visible to the sunbathers.
Offshore wind has taken a back seat to offshore drilling for oil and natural gas in the current energy debate. But those wind-driven turbines probably will be operating long before oil platforms appear off Atlantic Coast states.
Delaware hopes to be the first state to construct a wind farm off its coast. The project, scheduled to be completed in 2012, is one of several offshore wind proposals that have cleared significant hurdles in recent months.
Proponents say wind offers more long-term energy independence than offshore oil. Residents along the Eastern seaboard are embracing it as a stable-priced, environmentally friendly energy alternative.
“When people see the price of gas hit $4, they are very open to having discussions about alternatives,” said Stephen Smith, executive director of the Southern Alliance for Clean Energy, a nonprofit group.
Wind energy today accounts for only 1 percent of the nation’s electricity. A May report from the Energy Department concluded wind energy could generate 20 percent by 2030, with offshore sources accounting for nearly 20 percent of that. Projects mostly would be located along the Atlantic coast because the seabed floor elsewhere drops off too quickly to anchor turbines.
In Delaware, offshore wind has caught everyone’s imagination, said Patricia Gearity, a member of Citizens for Clean Power, a grass-roots organization based in the state.
Offshore wind supporters say recent proposals have not faced the same kind of opposition that previously dogged projects off Massachusetts’ Cape Cod and New York’s Long Island. But even on Cape Cod, attitudes are changing. Where critics once held a floating anti-wind farm demonstration, polls show that public opinion has swung in favor of an offshore project.
The Long Island project was scrapped last year. But fishermen in neighboring New Jersey who once opposed offshore wind power have banded together to submit one of five bids for a 350-megawatt wind farm that would produce enough electricity for up to 100,000 households. Rhode Island may select a developer this fall for a wind energy project.
Delaware residents took to the blogosphere, called their legislators and turned out in droves at public hearings to push for the proposed project off Rehoboth Beach. It stalled last year, but months of negotiations and strong grass-roots organizing resulted in its approval by the Delaware Legislature in June.
The project, proposed by Bluewater Wind, would include between 60 and 200 wind turbines spaced about a half mile apart. Delmarva Power has agreed to buy electricity from the project for 25 years. Bluewater is owned by the global investment firm Babcock Brown, which operates wind farms in several states.
For each turbine, a pole would be hammered about 90 feet below the seabed floor. Another pole would rise above the water with three 140-foot spinning blades at the top. At the highest point, the turbines would reach up about 400 feet; by comparison, the Washington Monument is about 555 feet.
