The report states that winds blowing off the Atlantic coast could provide four times more electricity each year than the region currently uses, and 12 of the 14 coastal states have offshore wind potential that exceeds their current electricity consumption,
It goes on to say that even if these 14 states converted all activities currently powered by gasoline, natural gas and other fossil fuels (such as transportation and home heating) to electricity, the energy provided by offshore wind turbines could still produce twice as much power as they would use.
“We’re facing rising seas, intensifying storms, and old and new health threats because we’ve relied so long on dirty energy sources,” said Rob Sargent, energy program director for Environment America. “But sitting right here next to us is the Atlantic Coast, and its winds provide a massive source of totally clean power.”
Offshore wind has been slow to take off in the United States. To date, only one wind farm is operating in the U.S., off the coast of Rhode Island. Meanwhile, Europe hosts 4,100 offshore wind turbines that supply enough electricity to power more than 20 million homes each day. But more American offshore wind is on the horizon. Thirteen leased offshore wind projects are now moving forward in the U.S., which could provide enough electricity to power approximately 5.2 million homes.
“Offshore wind off the Atlantic coast has the potential to power our communities for decades to come,” said Matthew Morrissey, Vice President for Deepwater Wind; which built the nation’s first offshore wind project off the coast of Rhode Island.
Advances in technology and declining costs, coupled with growing concern about the environmental impacts of fossil fuels, has contributed to the recent momentum.
According to the asset management firm Lazard, the overall cost of new offshore wind has declined by 25 percent in the last five years. Estimates by Bloomberg New Energy Finance predict the cost will decline by an additional 71 percent by 20401.
"Atlantic coastal states use more than a quarter of the nation’s energy,” said Gideon Weissman of Frontier Group, report co-author. "Offshore wind is the ideal resource for these states -- it’s clean, it’s renewable, and it’s conveniently located near our biggest cities.”
The report finds the Atlantic Coast, with its shallow waters and millions of people living close to shore, is especially well-suited for wind power. Recognizing this, governors and other state officials in New Jersey, New York, Massachusetts, Maryland, and Connecticut have established ambitious but feasible targets. If they meet these cumulative targets, offshore wind could potentially provide enough electricity to power 3 million homes.
“We’re beginning to see signs of a race to the top on offshore wind, with states adopting increasingly bold goals,” Sargent concluded. “We need Atlantic coast governors and other state leaders to commit to getting our energy from offshore wind.”
