California's offshore wind industry could be a casualty if President-elect Donald Trump makes good on his promise to sign an executive order to "end" the offshore wind industry. While he cannot do it with a stroke of a pen, California's offshore wind plans rely on a federal policy that offers billions of dollars in grants, subsidies and tax incentives. The technology is well on its way to being deployed in the ocean off California, which is counting on the clean energy source to meet its goals to scrub fossil fuels from the electric grid. Wind developers say they need certainty from state and federal partners that environmental policies will remain in place to reassure investors.
