Wave Energy and Wave Power: a small review

Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example for electricity generation, desalination, or the pumping of water (into reservoirs). Wave power is a renewable energy source.Though often co-mingled, wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents. Wave power generation is not currently a widely employed commercial technology although there have been attempts at using it since at least 1890. The world's first commercial wave farm is based in Portugal,at the Aguçadora Wave Park, which consists of three 750 kilowatt Pelamis devices.[...]
Recent developments on Wave Energy:

• Wave Energy: New System Captures Significantly More Wave Energy Than Existing Systems: Scientists have designed a pilot-scale device that will capture significantly more of the energy in ocean waves than existing systems, and have used it to power an electricity-generating turbine.[1]
• Wave Power Facility Successful in Sweden: A wave energy plant located in the sea outside Lysekil, Sweden has been quite successful. For nearly three years, a wave power plant has stood on the bottom of the ocean a couple of kilometers off the west coast of Sweden, near Lysekil. The station is uniquely durable and maintenance-free because of its simple mechanical construction.[2]
• Wave Energy Potential Warrants Further Research And Development, Says EPRI: 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. National Renewable Energy Laboratory (NREL) and energy agencies and utilities from six states.[3]
• Oregon May Lead Future Of Wave Energy: Significant advances in university research and other studies in the past two years are pointing toward Oregon as the possible epicenter of wave energy development in the United States. This may lead to a major initiative to expand a technology that is now in its engineering infancy, and tap the constant heave of the oceans for a new era of clean, affordable and renewable electrical power.[4]
