Want clean power? Catch a wave!

Californians might be surfing for power if one clean-energy proposal moves forward:

A new report from the Electric Power Research Institute (EPRI) suggests that generation of electricity from wave energy may be economically feasible in the near future. The study was carried out by EPRI in collaboration with the DOE's National Renewable Energy Laboratory (NREL) and energy agencies and utilities from six states.

Conceptual designs for 300,000 megawatt-hour (MWh) plants (nominally 120 MW plants operating at 40% capacity factor) were performed for five sites in the United States: Waimanalo Beach, Oahu, Hawaii; Old Orchard Beach, Cumberland County, Maine; WellFleet, Cape Cod, Massachusetts; Gardiner, Douglas County, Oregon; and Ocean Beach, San Francisco County, California.

The study determined 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.(For comparison land-based wind turbines currently generate 40,000 MW.)

"Wave energy will first become commercially competitive with land-based wind technology at a cumulative production volume of 10,000 or fewer MW in Hawaii and northern California, about 20,000 MW in Oregon and about 40, 000 MW in Massachusetts," said Roger Bedard, ocean energy project manager. This forecast was based on the output of a 90 MW Pelamis wave energy conversion plant design and application of technology learning curves that will enable cost savings.

With Californians aversion to building anything offshore, I'd place high odds on such a plan coming to fruiting in the Golden State.
