DOE published on 18th January two resource reviews indicate that waves and coastal tidal currents at the U.S. much could contribute electricity generation. Particularly high potential for wave energy development has the West Coast, including Alaska and Hawaii, while there are great opportunities for the wave energy on the East Coast. In addition, parts of both coasts have strong tides, which could be used to generate energy. In combination with other analyses, these evaluations show that water power 15% of U.S. electricity by the year 2030 could.
Of electricity per year about 4,000 terawatt hours (TWh) uses the United States. DOE estimates that the maximum theoretical electrical generation generated by waves and tidal currents around 1,420 TWh per year could be about a third of the country's total annual consumption. Although not all of the possible resource identified in these realistic assessments can be developed, a new water power development, highlighting opportunities still significant results are specific ways, to the 6% that already the nation power out to expand hydropower resources.
In addition to the wave and tidal resource reviews plans DOE of additional resources of assessments for ocean current, ocean of thermal gradients and new water power resources in the year 2012. To support the development of technologies that can tap into these massive resources, DOE's water is power program a detailed technical and economic assessment of companies to more accurately predict a variety of water power technologies, the opportunities and cost of development and deployment of this innovative technology. The program supports more than 40 demonstration projects that will advance the commercial readiness of these systems; provide first-of-a-kind performance data that will verify the cost of energy predictions in the water; and to identify ways for great cost savings. Progress, see the DOE attention and water power program website.
