April 25, 2023 — Tom Hafer remembers the first time the fish stopped biting. It was a little over 20 years ago when fiber optic cables were being installed in waters off the coast of central California, where he fishes commercially for spot prawns and rockfish. The fishing was disrupted for “miles and miles,” says Hafer, who has been fishing since the 1970s.
Now, he and many other fishermen are bracing themselves for what could be a much larger threat looming in the water. Offshore wind farms, which are ramping up in the United States, could come at a tremendous cost to fishermen as they are being sited in prime fishing areas. And the process of erecting wind farms and their long-term presence in the water could alter aquatic ecosystems, potentially driving away fish and marine mammals.
Some fishing communities also believe the physical infrastructure of offshore wind farms may pose a danger to fishing vessels and gear and the people who earn a livelihood from the sea.
There is little science to assuage those concerns. The floating wind farms being proposed along the West Coast rely on technologies that haven’t yet been commercially deployed. And the federal agency tasked with siting new farms—the U.S. Bureau of Ocean Energy Management (BOEM)—is new to the task.
Conceived in response to the BP oil spill in 2010, BOEM’s original charge was to oversee offshore oil in lieu of the former Minerals Management Service. BOEM has little experience with offshore wind and, so far, has been criticized for lack of thoroughness in vetting potential fishery conflicts.
Conflicts have also surfaced between BOEM and the nation’s top fisheries agency, NOAA Fisheries, as NOAA advises the agency in addressing concerns about fish health in an electrified sea. Recent reporting by ProPublica and The New Bedford Light has also raised concerns about relationships between the offshore wind industry and at least 90 of its regulators, including the Deputy Secretary of the Department of the Interior.
Offshore wind is a relatively new phenomenon in U.S. waters—the first commercial wind farm at sea was completed in 2016. That facility, Block Island Wind Farm, consists of five turbines off the coast of Rhode Island and is capable of producing 29 megawatts of power. That’s more than enough to supply all 17,000 homes on nearby Block Island, according to Ørsted, the Danish power company that acquired the installation in 2018.
But Block Island is a small fry compared to what’s coming, and that’s what has some critics worried. In 2021, the Biden administration set forth a lofty goal: By the end of the decade, it wants offshore wind farms to be producing 30 gigawatts of renewable energy in U.S. waters. Right now, Block Island and the two-turbine Coastal Virginia Offshore Wind pilot project are the only two commercial-scale facilities that have been completed, and together they’re capable of generating just 0.042 gigawatts, less than 1 percent of the Biden administration’s goal.
