^^^ I agree with scotty, there is no one way to solve the energy situation going on. There will probably be a combination of solutions that lead to a more equalized energy market, but I do believe that hydrocarbon based fuels will be the major percentage of human energy for long time to come.
I think we need to look at energy efficiency for the future. I mean, a IC engine in a car is about 30% thermally efficient, and the drive line is less than 90% efficient, so we only get to use less than 27% of the energy that is released by burning our gasoline.... Power plants have a similar efficiency level. If IC engines were made to be 60% efficent, you just cut the worlds dino-fuel consumption in half.....
Oh, and gas-hybrids are a band-aid, only diesel-hybrids seem to have enough of a difference in gas mileage to negate the cost over a conventional setup

P.S. We can hope for Fusion power for commercial.....Hope being the key word
