California intends to sue the Trump administration over its deal to end an offshore wind project proposed off the state’s central coast.

State officials said they are combating the administration’s attacks on their offshore wind industry by sending a notice of their intention to sue to the Department of the Interior on Tuesday. Tuesday’s action is focused on the administration buying back the lease for Golden State Wind, a floating offshore wind project off California’s central coast.

California has made a major commitment to offshore wind because of its potential to generate vast amounts of clean electricity from strong, consistent winds off its coast. Its strategy calls for the state to develop 25 gigawatts of offshore wind energy by 2045, enough to power roughly 25 million homes and provide about 13% of the state’s electricity supply.

These energy and climate goals are now in jeopardy, and that’s why California will fight vigorously, said California Energy Commission Chair David Hochschild. He called the administration’s strategy of buying back offshore wind leases “a strategic mistake of colossal proportions” that is especially stunning at a time when fossil fuel prices have been spiking due to the Iran war.

“Countries that thrive around the world are those that lean into innovation, into the energy sources of the future,” he said in an interview on Tuesday. “And so to turn away from this, and turn back the clock, and really engage in what I consider to be a war on innovation, is really ill-considered. And I think it’s a decision that’s not just bad for California, it’s bad for the nation.”
