Don't be concerned about running out of fossil fuels at this stage. The big problem is all the global warming hype. If this gets out of control and causes problems extracting oil from oil sands etc then live as we know it is finished. There are two ways to go from this point. Forget the environment and bring on plenty of nuclear power. Continue consuming all the fossil fuels you can find including turning coal into fuel. The greeny choice to stop using fossil fuels and to ride bikes appears to be the best thing for the environment but does not factor in the economic shock and massive unemployment that would more than likely end in WW3.
I think all pilots should be vermently opposed to the green movement and the idea of global warming.
