Offshore Wind: A Crucial Resource To Decarbonize The Western United States

This policy brief by Energy Innovation argues that floating offshore wind is a critical, untapped resource for decarbonizing the Western United States. While the U.S. currently lags behind other nations in offshore wind capacity, the authors contend that scaling this technology can diversify energy resources, reduce land-use conflicts, and provide reliable power during peak evening demand. The document outlines the economic potential for job creation and port revitalization, specifically highlighting projects in California, and provides policy recommendations for federal tax credits, infrastructure investment, and transmission planning to achieve net-zero emissions by midcentury.

• West Coast offshore wind is presented as a vital tool for meeting net-zero emissions goals, particularly as national electricity demand may triple by midcentury due to the electrification of transportation, industry, and buildings, as well as green hydrogen needs.
• Offshore wind can alleviate land-use conflicts in the Western U.S., where coastal states—which account for 57% of Western electricity demand—are among the most land-constrained, particularly California.
• The development of 10,000 MW of offshore wind in California by 2040 could generate between 120,000 and 180,000 job-years, including 4,000 permanent roles in operations and maintenance. Additionally, up to 50,000 new jobs could be created through 2040 if local component manufacturing is supported.
• Port infrastructure is a critical bottleneck for floating offshore wind because platforms must be assembled on shore and towed to their locations. For example, the Port of Humboldt Bay requires an estimated $130-$310 million for upgrades and $50-$100 million for floating platform fabrication, despite an initial $10.5 million grant from the California Energy Commission.
• Research from UC-Berkeley indicates that West Coast offshore wind is particularly valuable because it generates power during the early evening when the Western grid needs it most. Installing 50,000 MW off the California coast by 2045—representing 25% of the technical potential—could provide up to 40% of the state's total electricity in a net-zero grid.
• The U.S. significantly lags behind other nations in offshore wind; while 55,000 MW of fixed-bottom wind is deployed globally (primarily in China, Germany, and the UK), the U.S. has only two farms totaling 42 MW, representing less than 0.1% of global capacity.
• The U.S. Department of Energy predicts that the cost of floating offshore wind in the U.S. will drop from approximately $160/MWh in 2020 to between $60 and $105/MWh by 2030, with California expected to be at the lower end of that range.
• To scale the industry, the authors recommend that Congress extend the floating offshore wind production tax credit for 10 to 15 years at $25/MWh and invest in transmission infrastructure, which is estimated to cost between $0.75 and 2.5 billion per GW of installed capacity.
