Researchers at Bangor University say, in theory, one third of the world's electricity needs could be provided by the globe’s tidal range.
The review estimates that 5792 TWh could be produced by tidal range power plants - using tidal lagoons and barrages to convert energy from the predictable rise and fall of the world’s oceans.
However, 90% of the resource is distributed across just 5 countries, with both the UK and France having a significant share of that resource.
