Offshore renewable energy is poised to play a significant role in the nation's clean energy future, particularly along the U.S. West Coast, where floating offshore wind technology is nearing commercial scale. At the same time, West Coast waters support long standing and diverse maritime activities, including commercial, Tribal, and recreational fisheries, domestic and international shipping, port operations, and U.S. Coast Guard missions. As offshore renewable energy advances, understanding how these uses may interact is essential for informed planning and comprehensive decision making.Offshore Renewable Energy Development on the U.S. West Coast: Understanding Effects on Shipping, Fisheries, and Maritime Activities examines how offshore wind, wave, and tidal energy development may impact shipping routes, fisheries, port operations, and Coast Guard activities. Drawing on lessons from earlier offshore wind projects along the East Coast and current West Coast planning processes, this report identifies opportunities to proactively address potential conflicts, strengthen coordination, and support coexistence among ocean users.The report concludes that the West Coast's early stage of offshore renewable energy development presents a critical opportunity to align clean energy goals with maritime safety, fisheries sustainability, Tribal rights, and economic vitality. Through early engagement, transparent spatial planning, and coordinated governance, offshore renewable energy can be developed in ways that reduce undue burdens on coastal communities and existing ocean users while delivering broad public benefits.
