If Peak Oil even exists. I've read that Russian scientists believe that oil is a renewable source of energy produced through the action of heat and pressure on water and rock. (These conditions can actually be recreated in a lab and do produce oil, at least according to the link that follows).
They do not believe in the whole 'fossil fuel' business.
