“Offshore wind power is one promising source of energy that is commercially viable today. Researchers at the National Renewable Energy Laboratory estimate that the wind off America’s coast could generate nearly 1,000 gigawatts — a little more than the current U.S. electrical capacity.

Ocean power, while not as developed, is every bit as promising. California has more than 745 miles of coastline, and every mile has daily energy transfers in the form of waves, tides and current. Estimates vary, but experts suggest that more than a quarter of California’s energy demand could be met by technology that harnesses these forms of ocean energy. Economic projections indicate that ocean energy could become cost-competitive over the long term if governmental leadership exists to encourage investment in these technologies.”
