The “standard” approach is to start from the amount of resources that we have of a particular type, for example, oil in the ground, and see how far these resources will go. Growing development of technology seems to allow increasing amounts of these resources to be extracted. Thus, limits seem to be farther and farther in the distance, especially if a person starts out with an optimistic bias. It is easy to get this optimistic bias, with all research funds going in the direction of, “What can we do to solve our energy problems?”
Approaches for forecasting future supply problems that start from the amount of resources in the ground suffer from the problem that it is hard to draw a sharp line regarding when we will run into difficulties. It is clear that at some point, there will be a problem–EROEI (Energy Return on Energy Investment) will be too low–but exactly whenis hard to pinpoint. If a person starts from an optimistic viewpoint, it is easy to assume that as long as Energy Output is greater than Energy Input for a given process, that process must be helpful for solving our energy problem.
In fact, in my opinion, the story is very different. The very thing that should be saving us–technology–has side effects that bring the whole system down.
The only way we can keep adding technology is by adding more capital goods, more specialization, and more advanced education for selected members of society. The problem, as we should know from research regarding historical economies that have collapsed, is that more complexity ultimately leads to collapse because it leads to huge wage disparity.
