Global warming is neither here nor there in the matter of power generation. The pollution from hydrocarbons isn't the point, the point is that they will run out quite soon because we (that can of worms the 'world economy') are over-dependent on them.
So it seems quite a good idea to develop a range of other sources of power - wind, photo-electric, wave, tidal even - not to mention trying to get a proper hold on nuclear which does seem to suffer from governmental villainy and onanism - and also to evolve less wickedly extravagant and planet-trashing ways of using power without suffering the social unrest always caused by a perceived decline in living standards.
Damn tall order given our greedy and pig-headed nature.
