Cities Eye Ocean Waves for Power Supplies

Via Yahoo News comes this report on developing ocean energy projects in coastal cities around the U.S.: "whether captured by big buoys bobbing on sea swells, or by submerged turbines spinning with the ebb and flow of the tides, the energy potential of moving water, or marine power, is beginning to turn heads in the energy world."

The article follows publication of a report by the Electric Power Research Institute (EPRI) on the economic feasibility of wave power in the U.S.. The report, published in collaboration with the DOE's National Renewable Energy Laboratory (NREL), concludes that "wave energy conversion may be economically feasible within the territorial waters of the United States as soon as investments are made to enable wave technology to reach a cumulative production volume of 10,000 - 20,000 MW. (Land-based wind turbines, in comparison, generate 40,000 MW.)"

According to EPRI's Roger Bedard, the amount of wave energy available off the coasts of the United States is nine to ten times the energy currently generated by the country's hydroelectric dams
