Well that can't be true and in fact the Wikipedia article that I referenced states that annual worldwide increased energy demand from industrial sources is something like 10.6%. So industrial energy demand is something like 11 times the increase in population demand annually (but that;s got to be off a bit as about 2/3 energy consumption in the US is broadly industrial) and worldwide industrial demand is something > 9 times energy demand from the population.
I was thinking that the industrial demand coefficient would have been closer to 2 or that a low exponent would have been possible. But it can't really be. So actually annual energy demand increase from all sources is linear. Humanity can if fact provide energy nearly indefinitely even with coal and oil running out although it will require quite a shift in energy production. From an engineering perspective this is straightforward.
However we lack the worldwide political leadership as all societies worldwide are flatout leadership failures. Perhaps if Germany continues to hit their renewable goals more rational nations like the Scandinavian countries, New Zealand, maybe Canada, maybe the more rational North African countries will get on board and become bastions of civilization.
