Eventually he believes wave power could supply 20% of the UK's energy needs, the same proportion currently supplied by nuclear.

That would force power companies to take more of their supply from green energy sources, like wave and tidal power.

FoE Scotland chief executive Duncan McLaren said wave and tidal power could supply a fifth of UK energy needs and that Scotland was ideally placed to generate a significant amount of that energy.
