Supply is another matter. U.S. oil production peaked three decades ago. As soon as global oil production peaks in the next several years, the ensuing down-slope will not be gentle. Demand, with world trade relying on oil for shipping, is about to meet ever- shrinking supply. Estimates of when this shortfall is to hit put it quite possibly during Bush's tenure at the White House.
Natural gas is on a bell curve of depletion similar to oil.
As for coal, it is the least attractive fossil fuel - not just from the pollution standpoint. There is not much anyone can do about the energy picture except conserve to the max, even with a concerted all-out effort to encourage the use of renewable energy. Even though renewables will be vital, they don't have high net-energy ratios, and renewables do not yield much in the way of asphalt, tires, pesticides and other pillars of industrial living, that oil does for consumers. The size of our population puts us way out on a limb of petroleum dependence. The end of abundant, cheap oil means the end of our culture of overconsumption.
