The U.S. Department of Energy (DOE) today released two nationwide resource assessments showing that waves and tidal currents off the nation's coasts could contribute significantly to the United States' total annual electricity production, further diversify the nation's energy portfolio, and provide clean, renewable energy to coastal cities and communities. These new wave and tidal resource assessments, combined with ongoing analyses of the technologies and other resource assessments, show that water power, including conventional hydropower and wave, tidal, and other water power resources, can potentially provide 15% of our nation's electricity by 2030. Today's reports represent the most rigorous analysis undertaken to date to accurately define the magnitude and location of America's ocean energy resources. The information in these resource assessments can help to further develop the country's significant ocean energy resources, create new industries and new jobs in America, and secure U.S. leadership in an emerging global market.
The two reports—"Mapping and Assessment of the United States Ocean Wave Energy ResourcePDF" and "Assessment of Energy Production Potential from Tidal Streams in the United StatesPDF"—calculate the maximum kinetic energy available from waves and tides off U.S. coasts that could be used for future energy production, and which represent largely untapped opportunities for renewable energy development in the United States.
