When the Economy Gets Squeezed by Too Little Energy
When people forecast ever-rising energy prices, they miss the fact that market fossil fuel prices consider both oil producers and consumers. From the producer’s point of view, the price for oil needs to be high enough that new oil fields can be profitably developed. From the consumer’s point of view, the price of oil needs to be sufficiently low that food and other goods manufactured using oil products are affordable. In practice, oil prices tend to rise and fall, and rise again. On average, they don’t satisfy either the oil producers or the consumers. This dynamic tends to push the economy downward.

Ramping up wind turbines, solar panels and electric vehicles can’t solve our energy problem
Many people believe that installing more wind turbines and solar panels and manufacturing more electric vehicles can solve our energy problem, but I don’t agree with them. These devices, plus the batteries, charging stations, transmission lines and many other structures necessary to make them work represent a high level of complexity.
A relatively low level of complexity, such as the complexity embodied in a new hydroelectric dam, can sometimes be used to solve energy problems, but we cannot expect ever-higher levels of complexity to always be achievable.
According to the anthropologist Joseph Tainter, in his well-known book, The Collapse of Complex Societies, there are diminishing returns to added complexity. In other words, the most beneficial innovations tend to be found first. Later innovations tend to be less helpful. Eventually the energy cost of added complexity becomes too high, relative to the benefit provided. Continue reading

2023: Expect a financial crash followed by major energy-related changes
If the world economy experiences major financial turbulence in 2023, we could be in for a rough ride. In my opinion, a major financial crash seems likely. This is could upset the economy far more seriously than the 2008 crash.
I am certain that some mitigation measures can be implemented. For example, there can be a major push toward trying to make everything that we have today last longer. Materials can be salvaged from structures that are no longer used. And some types of local production can be ramped up.
We can keep our fingers crossed that I am wrong but, with less oil and other energy resources available per person, moving goods shorter distances makes sense. Thus, the initial trends we are seeing toward regionalization are likely to continue. The move away from the US dollar as the reserve currency also looks likely to continue. Moreover, if the changes I am talking about don’t occur in 2023, they are likely to begin in 2024 or 2025. Continue reading
The economy is moving from a tailwind pushing it along to a headwind holding it back
When the Crisis Stage occurs, there are fewer goods and service per capita to go around, so some members of the world economy must come out behind. Conflict of all kinds becomes more likely. Political leaders, if they happen to discover the predicament the world economy is in, have little interest in making the predicament known to voters, since doing so would likely lead them to lose the next election.
Instead, the way the physics-based self-organizing economic system works is that alternative narratives that frame the situation in a less frightening way gain popularity. Political leaders may not even be aware of how dependent today’s economy is on fossil fuels. Researchers may not be aware that their “scientific” models are misleading because they look at too small a portion of the overall system and make unwarranted assumptions. Continue reading
