The sun acts as the primary driving force, causing winds and temperature differences that impact currents. Ocean thermal energy conversion, which generates power from the temperature difference between warm surface seawater and cold seawater at 800-1,000 metres depth. The constant pounding of the waves and the ebb and flow of tidal currents, as well as other properties of the ocean, if harnessed, could produce 20,000 to 80,000 terawatt hours of electricity, according to the International Energy Agency. Tides and climatic currents have moving at about 110 mph. Policies promoting R&D are needed to achieve further cost reductions and large-scale development. That is more than the world's current energy consumption of almost 20,000 TWh The ocean energy industry has made significant progress in recent years but is still at a very early stage with some advanced prototypes that are just tested [2]. Ocean Energy Data Tides, waves and currents can be used to produce electricity. Tidal stream (or current) technologies capture the kinetic energy of currents flowing in and out of tidal areas (such as seashores). 1. Power generation by ocean temperature difference through expension of heated liquid CN 1162698. Ocean currents are one of important resources of ocean energy. World tidal energy resources have been estimated at around 3000 GW, however less than 3% of this is located in areas considered suitable for power generation (these figures probably don't include ocean current power, which doesn't seem to be well studied). Ocean currents, one of the largest untapped renewable energy resources on the planet, show a global potential of over 450,000 MW (450 GW) and representing a market of more than US$550 billion. Ocean waves contain tremendous energy. Although it is not widely harnessed at present, ocean current power has a vital potential for future electricity generation. For example, the flow velocity is larger at rising and falling tide, smaller in the remaining period, the flow direction changes too fast, etc. (1) Ocean currents do not vary significantly in speed and direction at any time day or night all year round.
