Peak oil has taken on the trappings of an apocalyptic religion recently. True believers tout "Hubbert Curves" and "Simmons Depletion Analyses" in circular jerkulars and echo choruses across the webosphere. Oil should be well over $500 a barrel by now, according to not-so-distant predictions of the peakers -- some dead and some alive. But oil is in the $80 range largely due to a combination of the weak Obama dollar, the speculative lemming's rush to a safe investment haven, and a misleading surge in demand from India, China, and Brasil.
But ignoring the doomseekers, what are the actual hydrocarbon resources which we have to deal with? Below are some rather conservative early estimates of hydrocarbon resources -- neglecting the vast terrestrial and sub-sea coal and methane clathrate resources. It may take a while to achieve "peak oil" when you consider how quickly industry is developing means of converting these unconventional hydrocarbons to conventional liquid fuels.
The outlook expressed above is remarkably rosy when viewed from a doomer's perspective. But in reality, the resource estimates are likely to be far too low in the long run.
It is all a moot point, however, because long before conventional oil is exhausted, humans in advanced countries will have begun to shift to resources which are essentially inexhaustible, such as advanced interlocking fuel cycles of nuclear fission, microbial biofuels, and perhaps nuclear fusion.
I know it hurts but it's good for you. Groupthink is bad...very, very bad.
