Oil is not a fossil fuel. Hydrogen and Carbon trapped under the earth’s crust are squeezed together to form hydrocarbons. By one estimate, we have already burned more oil that could possibly be accounted for by all the biomass ever produced by all living things ever. Further, the Russians have successfully drilled on the basis of the hydrocarbon (non-fossil-fuel) theory for decades. Finally, “Peak Oil” was in part predicated on the idea of fossils, and we know how that turned out. “Fossil Fuel” is a red herring.
You’re saying petroleum products do not derive from dead dino bones?
I've tried to tell people that percolating petro from deep under ground gets trapped in some formations, like salt domes and shale beds. That sedimentary formations get polluted with old compressed plant life. That oil, were it not dirtied up from these traps is greenish yellow, low sulfur, bunker grade crude. But they ain't having any.
