Tide and waves could be secure ways to generate electricity – and unlike other energy sources, do not rely on imports or global markets.
Tide and wave power schemes are subject to intermittency. The magnitude of waves depends on the strength of the wind, and tidal systems vary with the ebb and flow of the tides.
Marine power based on tide and waves could improve the overall security of the UK energy mix by reducing our reliance on imported fossil fuels.
The Department of Energy and Climate Change estimates that wave and tidal energy has the potential to meet up to 20% of the UK’s current electricity demand.
