As the climate of the world changes the global community searches for sources of clean and renewable energy, that will not cost the earth.
European companies, with the support of central governments and the European Union, are positioning themselves to lead the world in tidal energy generation technology.
The UK is at the forefront of developments within the tidal power sector and the geography of the region provides it with massive potential.
Studies have suggested that one-third of the UK's total electricity needs could be met by tidal power alone, and Alex Salmond, Scotland's first minister, predicted that the Pentland Firth region, where the north-east Atlantic meets the North Sea, will become the "Saudi Arabia" of marine energy.
The Severn tidal barrage stretching from Cardiff to Weston-super-Mare could alone generate about 5% of the UK's annual electricity requirements.
