I agree with Boab – surely hydro-power is the way forward. The good news in the UK is that an experimental wave turbine was commissioned in the Bristol Channel last year. It will be interesting to see the results of that. The UK has so many tidal inlets the prospects should be good, although I believe one 'expert' has discounted the Thames estuary as being the wrong sort of tidal flow. I dunno, I'm a simple soul, the tide comes in – power, the tide goes out again – more power. It's obviously not as simple as that.
Solar power is another good prospect. Deputy PM John Prescott has recently stated that all new houses should have solar power fitted as standard (Ooh look, there goes a pig flying by!). In Greece you'd be hard pushed to see a house that doesn't have solar panels on the roof. I know it's much sunnier than the UK, but there are solar panels on the market that work perfectly well in our environment. Of course this would not solve the demands of industry but it has to be better that the present situation.

Mind you, if we could only harness the power of all the hot air expounded on Mudcat then all our problems would be over….
