Potential energy resources available from the ocean significantly exceed worldwide demand for energy but they are not presently accessible, either technically or as economically competitive alternatives to current low cost energy sources—coal, oil, gas and geothermal energy. Increasing the contribution of ocean energy to meet growing international energy demand will require substantial investment in research and development, demonstrations, deployments and diffusion of commercial technologies. Nonetheless, all forms of ocean energy are emissions-free (barring construction, deployment and decommissioning activities) and will become cheaper and more attractive alternatives to the presently predominant forms of fossil fuel as emissions trading, carbon taxes and the full cost of externalities are priced into the cost of fossil fuel sources. The limitations on the extent to which ocean energy will be developed are factors such as unit cost of generated electricity (compared with other renewable technologies), reliability and operations and maintenance costs.
