U.S. Department of Energy Releases New Wave & Tidal Energy Assessment Reports


Reports demonstrate major potential for wave and tidal energy production near U.S. coasts, Alaska & Hawaii


The U.S. Department of Energy (DOE) today released two reports detailing the country's ocean wave and tidal resource energy potential. Mapping and Assessment of the United States Ocean Wave Energy Resource report is a follow-up to the Electric Power Research Institute's (EPRI) 2004 study, with the most recent evidence suggesting a 26 percent increase in wave energy resources.

The Assessment of Energy Production Potential from Tidal Streams in the United States, led by researchers at Georgia Tech Research Corporation in collaboration with DOE, is the first of its kind in the U.S. and includes a geographic information systems (GIS) tool available for public use. The report data concludes that U.S. water power resources, including ocean wave, tidal and conventional hydropower, have the potential to provide 15 percent of our nation's electricity by 2030.

"The release of both reports demonstrates the attainable energy potential of our nation's vast ocean resources,” said Sean O'Neill, OREC's President. "DOE's investment in these studies, as well as the corresponding results, is a testament to the importance of our unique opportunity to pursue a diverse energy portfolio that includes wave and tidal energy in an effort to secure our energy supply, create jobs and lower greenhouse gas emissions.”

The reports are the most rigorous assessments thus far undertaken by DOE and its collaborative partners, and show the significant renewable energy contributions that waves and tidal currents off of U.S. coasts could provide to the grid. DOE announced the information in the resource assessments could "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 wave energy assessment concludes that the Pacific Ocean off the West Coast (Washington, Oregon and California) and Alaska encompass the greatest available wave energy resources in the U.S. The report also outlines the wave energy potential along the East Coast from Maine through North Carolina, and from South Carolina through Florida as well as in the Gulf of Mexico, Alaska's Bering Sea, Hawaii and Puerto Rico.

The tidal energy assessment designates and details data for energy resource 'hot spots' across the U.S. including Alaska, Maine, Washington, Oregon, California, New Hampshire, Massachusetts, New York, New Jersey, North Carolina, South Carolina, Georgia and Florida.


About the Ocean Renewable Energy Coalition

The Ocean Renewable Energy Coalition (OREC) is the only national trade association exclusively dedicated to promoting marine and hydrokinetic renewable energy technologies from clean, renewable ocean resources. Founded in April of 2005, the Coalition has grown to over 60 members including technology developers, consultants, law firms, investor-owned utilities, publicly owned utilities, universities, and scientific and engineering firms. The coalition is working with industry leaders, academic scholars, and other interested NGO's to encourage ocean renewable technologies and raise awareness of their vast potential to help secure an affordable, reliable, environmentally friendly energy future.

OREC seeks a legislative and regulatory regime in the U.S. that fosters the growth of ocean renewable technologies, their commercial development, and support in the race to capture the rich energy potential of our oceans. While other countries have already deployed viable, operating, power generating projects using the emission-free power of ocean waves, currents, and tidal forces, the U.S. is only beginning to acknowledge the importance of these technologies.
