The rate of technological change is so fast—that its not prudent to out past ten years as to the price of energy.
My own opinion is that US oil demand is going to go into a death spiral which will put permanent downward pressure on the price oil.
That downward pressure will come from two directions. the first is the pickens plan which is pushing big vehicles over to natural gas.
the second is Tesla motors. here my confidence is not so much in the electric car but the guy who heads up the company: Elon Musk. He is in the same league as bill gates and bill jobs.
then there’s just the unknown. the last five years have produced several big changes in the internet including the move to hand held devices and the social web. in the energy patch the last five years have produced the fracking revolution.
Its quite likely the next five years will produce equally stunning changes. the five years after that will likely do the same thing again.
10 years from now the world will be science fiction to us now.
