Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter (WEC).
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. In 2008, the first experimental wave farm was opened in Portugal, at the Aguçadoura Wave Park.
