This is a bloody parochial thread! Complaining that groundnut oil (or whatever) is $2.99 a gallon - I would be glad to fill my diesel powered car at that rate. Just because California doesn't know its arse from its elbow at the moment does not change the fact that in 20 years time you will be paying $29.9 a gallon for your fuel, if you're really lucky. All this faffing about hydrogen as a fuel ignores the fact that it takes about twice the amount of enengy to make the hydrogen than you can ever get out out of it! Wind power - it takes an entire turbine farm to get enough energy to run a 40% of a single Sainsbury (a spermarket chain) depot in the South of England. Solar Energy - as mentioned in other messages, it still has barely reached its break-even point in terms of the construction of the solar conversion units. Hydro-power - already probably reached its effective limits - its been developed the longest. Tidal power - probably has still some mileage, but is limited both in application (there aren't many suitable sites which will stay in one piece) and in time (they tend to silt up).

Hydrogen fusion has been on the brink of a break through since as long as I can remember - in the 1950's.

Thre does not seem to be anything on the horizon - but we do know that fission does work and it seems to be the only thing that will keep us warm in winter.
