A few years ago, especially in the 2005-2008 period, many people were concerned that the oil supply would run out. They were concerned about high oil prices and a possible need for rationing. The story was often called “Peak Oil.” Peak Oil theorists have also branched out into providing calculations that might be used to determine which substitutes for fossil fuels seem to have the most promise. What is right about the Peak Oil story, and what is misleading or wrong? Let’s look at a few of the pieces.
 What Is the Role of Energy in the Economy?
The real story is that the operation of the economy depends on the supply of affordable energy. Without this energy supply, we could not make goods and services of any kind. The world’s GDP would be zero. Everything we have, from the food on our dinner table, to the pixels on our computer, to the roads we drive on is only possible because the economy “dissipates” energy. Even our jobs depend on energy dissipation. Some of this energy is human energy. The vast majority of it is the energy of fossil fuels and of other supplements to human energy.
Peak Oilers generally have gotten this story right, but they often miss the “affordable” part of the story. Economists have been in denial of this story. A big part of the problem is that it would be problematic to admit that the economy is tied to fossil fuels and to other energy sources whose supply seems to be limited. It would be impossible to talk about growth forever, if economic growth were directly tied to the consumption of limited energy resources.

Financial markets have been behaving in a very turbulent manner in the last couple of months. The issue, as I see it, is that the world economy is gradually changing from a growth mode to a mode of shrinkage. This is something like a ship changing course, from going in one direction to going in reverse. The system acts as if the brakes are being very forcefully applied, and reaction of the economy is to almost shake.
What seems to be happening is that the world economy is reaching Limits to Growth, as predicted in the computer simulations modeled in the 1972 book, The Limits to Growth. In fact, the base model of that set of simulations indicated that peak industrial output per capita might be reached right about now. Peak food per capita might be reached about the same time. I have added a dotted line to the forecast from this model, indicating where the economy seems to be in 2019, relative to the base model.1
Figure 1. Base scenario from The Limits to Growth, printed using today’s graphics by Charles Hall and John Day in Revisiting Limits to Growth After Peak Oil with dotted line at 2019 added by author. The 2019 line is drawn based on where the world economy seems to be now, rather than on precisely where the base model would put the year 2019.
The economy is a self-organizing structure that operates under the laws of physics. Many people have thought that when the world economy reaches limits, the limits would be of the form of high prices and “running out” of oil. This represents an overly simple understanding of how the system works. What we should really expect, and in fact, what we are now beginning to see, is production cuts in finished goods made by the industrial system, such as cell phones and automobiles, because of affordability issues. Indirectly, these affordability issues lead to low commodity prices and low profitability for commodity producers. For example:
- The sale of Chinese private passenger vehicles for the year of 2018 through November is down by 2.8%, with November sales off by 16.1%. Most analysts are forecasting this trend of contracting sales to continue into 2019. Lower sales seem to reflect affordability issues.
- Saudi Arabia plans to cut oil production by 800,000 barrels per day from the November 2018 level, to try to raise oil prices. Profits are too low at current prices.
- Coal is reported not to have an economic future in Australia, partly because of competition from subsidized renewables and partly because China and India want to prop up the prices of coal from their own coal mines.
