It's probably stupid idealistic naiveity but I've often wondered why
renewables can't eventually produce 100% of the world's energy
requirements.

Enough pump storage systems could surely buffer the demands of the
'Eastenders' broadcast on a cold Boxing day.
Enough tidal power systems would surely provide an entirely predictable

A company which operates near here - http://www.engb.com/ has spent a
lot of their own and gov money on tidal energy.

They have concluded that it is not a viable source of significant amounts
of energy


Meanwhile, at Scapa Flow, the reverse applies and wave energy is
considered both viable and highly significant. The possibility of
exporting surplus to the mainland (Europe) has been mentioned.
