Abstract
Against the background of the current world facing an energy crisis, and human beings puzzled by the problems of environment and resources, developing clean energy sources becomes the inevitable choice to deal with a climate change and an energy shortage. A global ocean wave energy resource was reanalyzed by using ERA-40 wave reanalysis data 1957-2002 from European Centre for Medium-Range Weather Forecasts (ECMWF). An effective significant wave height is defined in the development of wave energy resources (short as effective SWH), and the total potential of wave energy is exploratively calculated. Synthetically considering a wave energy density, a wave energy level probability, the frequency of the effective SWH, the stability and long-term trend of wave energy density, a swell index and a wave energy storage, global ocean wave energy resources were reanalyzed and regionalized, providing reference to the development of wave energy resources such as wave power plant location, seawater desalination, heating, pumping.
