$this->bbcode_second_pass_quote('outcast', 'G')lobal energy per capita as a tool for evaluation whether or not industrial civilization will collapse fails because it does not take into account that the vast majority of population growth during that time has happened in non-industrial civilizations, which makes the Olduvai theory kind of flawed.
I imagine that Duncan would probably agree that energy per capita is problematic in that energy usage is not uniformly distributed among the world population. But I don’t think this fact invalidates his basic argument.
It seems to me that the crucial question is: how dependent is a given culture/nation upon abundant energy sources?
For example, when I visited Europe a few years back, it was clearly obvious to me that much of Europe developed under conditions of relative energy scarcity. The layout of housing and businesses is completely different than in the US, where there are typically great distances between homes and workplaces, markets, etc. Americans are “hooked-in” or formally dependent upon oil - in particular - in order for the culture to function as designed. So in that sense, Europe, because it developed under conditions of relative energy scarcity, will be much better positioned to transition to a lower energy way of life. The lower per capita energy use of Europe probably reflects these differences, which are historical in nature.
Similarly, third world de-industrialized nations are probably going to be much better positioned to deal with declines in energy because they never developed a dependence on FFs in order to live. This is not uniformly true, but I think it is broadly accurate.
In terms of energy per capita, it might be more effective to limit the calculation to industrialized countries, and in particular, taking into account energy required for transportation, a sector where oil is vital.
Certainly, people can disagree about the shape of the energy per capita curve going forward, but it seems inescapable to me that at some point it will be impossible for industrialized nations, particularly the US, to function as designed. And I agree with Duncan that one critical weakness is the electrical distribution system. It remains to be seen whether the US will be able to maintain its relative affluence, so as to enable continued use of a disproportionate energy per capita. If it can, Duncan’s cliff might be more like the slide, extending over several decades. If not, the cliff might be much more dramatic.
