@nelderini SmartPlanet: "Oil production per capita peaked in 1979 at 5.5 barrels of oil per person per year, Laherrère calculates. That rate that can never be matched again, he says, because population continues to grow even as global oil production has hit a plateau, soon to be followed by an inevitable decline. By 2050, Laherrère calculates that the global per-capita oil consumption will have to fall to around half the 2012 level."
