IT could be the solution to our energy needs. An inexhaustible source of free power, always available and able to meet as much as 30pc of global energy demand.
Not only is there potential to produce power from the ocean, there's also the opportunity for job creation, supply chain development and a more diverse and secure energy mix.
Theoretically, the energy contained in the seas is estimated to be 32,000 terrawatt hours per year (TWh/yr) for wave energy and 7,800 TWh/yr for tides. By comparison, worldwide electricity demand is around 18,000 TWh/yr.
