Domestic and international attention is heavily focused on solar, wind, geothermal, wave and the relatively new fields of ocean current, tidal and river power.  All of these ‘green energy sources’ have important roles to play in meeting new energy demand by displacing the world’s non-renewable fossil fuels based infrastructure, and reducing carbon emissions.

Of these, only oceans and rivers and the embryonic deep geothermal (hot rocks) sectors have the potential to compete directly with nuclear and coal powered generators for the supply of predictable and baseload electricity.  

Predictable and baseload ‘green’ electricity supplies are by far the largest potential future markets for renewable energy technologies.

For this reason, ocean currents, tides and flowing rivers are increasingly recognised as major renewable energy sources.
