It is now popular to talk about leaving fossil fuels to prevent climate change. Pretty much the same result occurs if we run short of fossil fuels: We lose fossil fuels, but it is because we cannot extract them. Practically no one tells us about the extent to which the current system depends upon fossil fuels, however.

The economy is extraordinarily dependent on fossil fuels. If there are not enough fossil fuels to go around, there is likely to be fighting over what is available. Some countries are likely to get far more than their fair share, while the rest of the world’s population will be left with very little or no fossil fuels.

If losing fossil fuels completely, or nearly completely, is a risk for some of the world’s population, it might be useful to think through some of the things that go wrong. The following are some of my ideas about things that change, mostly for the worse, in a fossil fuel-deprived economy.

[1] Banks, as we know them, will likely fail.

Before banks fail in areas with virtually no fossil fuels, my guess is that we will generally see hyperinflation. Governments will greatly increase the money supply in a vain attempt to get people to believe that more goods and services are being produced. This approach will be used because people equate having more money with the ability to buy more goods and services. Unfortunately, without fossil fuels it will be very difficult to produce very many goods.

More money will simply provide more inflation because it takes physical resources, including the proper types of energy, to operate machinery of all kinds to make goods. Creating services also requires fossil fuel energy, but generally, to a lesser extent than creating goods…

Today’s energy bottleneck may bring down major governments

Today’s energy bottleneck may bring down major governments

Recently, I explained the key role played by diesel and jet fuel. In this post, I try to explain the energy bottleneck the world is facing because of an inadequate supply of these types of fuels, and the effects such a bottleneck may have. The world’s self-organizing economy tends to squeeze out what it considers non-essential parts when bottlenecks are hit. Strangely, it appears to me that some central governments may be squeezed out. Countries that are rich enough to have big pension programs for their citizens seem to be especially vulnerable to having their governments collapse.

Figure 1. World supply of diesel and jet fuel per person, based on Middle Distillate data of the *2023 Statistical Review of World Energy,* produced by the Energy Institute. Notes added by Gail Tverberg.

This squeezing out of non-essential parts of the economy can happen by war, but it can also happen because of financial problems brought about by “not sufficient actual goods and services to go around.” An underlying problem is that governments can print money, but they cannot print the actual resources needed to produce finished goods and services. I think that in the current situation, a squeezing out for financial reasons, or because legislators can’t agree, is at least as likely as another world war.

For example, the US is having trouble electing a Speaker of the House of Representatives because legislators disagree about funding plans. I can imagine a long shutdown occurring because of this impasse. Perhaps not this time around, but sometime in the next few years, such a disagreement may lead to a permanent shutdown of the US central government, leaving the individual states on their own. Programs of the US central government, such as Social Security and Medicare, would likely disappear. It would be up to the individual states to sponsor whatever replacement programs they are able to afford.

Fossil Fuel Imports Are Already Constrained

August 31, 2023

Fossil Fuel Imports Are Already Constrained

For many years, there has been a theory that imports of oil would become a problem before there was an overall shortage of fossil fuels. In fact, when I look at the data, it seems to be clear that oil imports are already constrained.

Figure 1. Interregional trade of fossil fuels based on data of the *2023 Statistical Review of World Energy* by the Energy Institute.

As I look at the data, it appears to me that coal and natural gas imports are becoming constrained, as well. There was evidence of this constrained supply in the spiking prices for these fuels in Europe in late 2021 and early 2022, starting well before the Ukraine conflict began.

Oil, coal, and natural gas are different enough from each other that we should expect somewhat different patterns. Oil is inexpensive to transport. It is especially important for the production of food and for transportation. Prices tend to be worldwide prices.

Coal and natural gas are both more expensive to transport than oil. They tend to be used in industry, in the heating and cooling of buildings, and in electricity production. Their prices tend to be local prices, rather than the worldwide price we expect for oil. Prices for importers of these fuels can jump very high if there are shortages.

In this post, I first look at the trends in the overall supply of these fuels, since a big part of the import problem is fossil fuel supply not growing quickly enough to keep pace with world population growth. I also give more background how the three fossil fuels differ.

Our Oil Predicament Explained: Heavy Oil and the Diesel Fuel it Provides Are Key

August 4, 2023

Our Oil Predicament Explained: Heavy Oil and the Diesel Fuel it Provides Are Key

It has recently become clear to me that heavy oil, which is needed to produce diesel and jet fuel, plays a far more significant role in the world economy than most people understand. We need heavy oil that can be extracted, processed, and transported inexpensively to be able to provide the category of fuels sometimes referred to as Middle Distillates if our modern economy is to continue. A transition to electricity doesn’t work for most heavy equipment that is powered by diesel or jet fuel.

A major concern is that the physics of our self-organizing economy plays an important role in determining what actually happens. Leaders may think that they are in charge, but their power to change the way the overall system works, in the chosen direction, is quite limited. The physics of the system tends to keep oil prices lower than heavy oil producers would prefer. It tends to cause debt bubbles to collapse. It tends to squeeze out “inefficient” uses of oil from the system in ways we wouldn’t expect. In the future, the physics of the system may keep parts of the world economy operating while other inefficient pieces get squeezed out.

In this post, I will try to explain some of the issues with oil limits as they seem to be playing out, particularly as they apply to diesel and jet fuel, the major components of Middle Distillates.

[1] The most serious issue with oil supply is that there seems to be plenty of oil in the ground, but the world economy cannot hold prices up sufficiently high, for long enough, to get this oil out.

Models Hide the Shortcomings of Wind and Solar

Models Hide the Shortcomings of Wind and Solar

A major reason for the growth in the use of renewable energy is the fact that if a person looks at them narrowly enough–such as by using a model–wind and solar look to be useful. They don’t burn fossil fuels, so it appears that they might be helpful to the environment.

As I analyze the situation, I have reached the conclusion that energy modeling misses important points. I believe that profitability signals are much more important. In this post, I discuss some associated issues.

Overview of this Post

In Sections [1] through [4], I look at some issues that energy modelers in general, including economists, tend to miss when evaluating both fossil fuel energy and renewables, including wind and solar. The major issue in these sections is the connection between high energy prices and the need to increase government debt. To prevent the continued upward spiral of government debt, any replacement for fossil fuels must also be very inexpensive–perhaps as inexpensive as oil was prior to 1970. In fact, the real limit to fossil fuel extraction and to the building of new wind turbines and solar panels may be government debt that becomes unmanageable in an inflationary period.

In Section [5], I try to explain one reason why published Energy Return on Energy Investment (EROEI) indications give an overly favorable impression of the value of adding a huge amount of renewable energy to the electric grid. The basic issue is that the calculations were not set up for this purpose. These models were set up to evaluate the efficiency of generating a small amount of wind or solar energy, without consideration of broader issues. If these broader issues were included, EROEI indications would be much lower (less favorable).

The Fed Cannot Fix Today’s Energy Inflation Problem

April 10, 2023

The Fed Cannot Fix Today’s Energy Inflation Problem

There is a reason for raising interest rates to try to fight inflation. This approach tends to squeeze out the most marginal players in the economy. Such businesses and governments tend to collapse, as interest rates rise, leaving less “demand” for oil and other energy products. The institutions that are squeezed out range from small businesses to financial institutions to governmental organizations. The lower demand tends to reduce inflationary pressure.

The amount of goods and services that the world’s economy can produce is largely determined by fossil fuel supplies, plus our ability to use “complexity” in many forms to produce the items that the world’s growing population requires. Adding debt helps add complexity of various types, such as more international trade, more advanced education, and more specialized tools. For a while, the combination of growing energy supplies and growing complexity have helped pull economies along.

Unfortunately, the world’s oil supply is no longer growing. Without an adequate oil supply, it becomes difficult to maintain complexity because complex solutions, such as international trade, require adequate oil supplies. Inasmuch as we seem to be reaching energy and complexity limits, nothing the regulators try to do to change the debt and money supplies–even reeling them back in–can fix the underlying oil (and total energy) problem.

I expect that the rich parts of the world, including the US, Europe, and Japan, are in line to be adversely affected by high interest rates this time. With their high levels of complexity, they are among the most vulnerable to disruption when there is not enough oil to go around.

Ramping up wind turbines, solar panels and electric vehicles can’t solve our energy problem

February 13, 2023

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.

In this post, I will discuss complexity further. I will also present evidence that the world economy may already have hit complexity limits. Furthermore, the popular measure, “Energy Return on Energy Investment” (EROEI) pertains to direct use of energy, rather than energy embodied in added complexity. As a result, EROEI indications tend to suggest that innovations such as wind turbines, solar panels and EVs are more helpful than they really are. Other measures similar to EROEI make a similar mistake.

[1] In this video with Nate Hagens, Joseph Tainter explains how energy and complexity tend to grow simultaneously, in what Tainter calls the Energy-Complexity Spiral.

Figure 1. The Energy-Complexity Spiral from 2010 presentation called *The Energy-Complexity Spiral* by Joseph Tainter.

According to Tainter, energy and complexity build on each other. At first, growing complexity can be helpful to a growing economy by encouraging the uptake of available energy products…

2023: Expect a financial crash followed by major energy-related changes

2023: Expect a financial crash followed by major energy-related changes

Why is the economy headed for a financial crash? It appears to me that the world economy hit Limits to Growth about 2018 because of a combination of diminishing returns in resource extraction together with rising population. The Covid-19 pandemic and the accompanying financial manipulations hid these problems for a few years, but now, as the world economy tries to reopen, the problems are back with a vengeance.

Figure 1. World primary energy consumption per capita based on BP’s *2022 Statistical Review of World Energy*. Same chart shown in post, *Today’s Energy Crisis Is Very Different from the Energy Crisis of 2005*.

In the period between 1981 and 2022, the economy was lubricated by a combination of ever-rising debt, falling interest rates, and the growing use of Quantitative Easing. These financial manipulations helped to hide the rising cost of fossil fuel extraction after 1970. Even more money supply was added in 2020. Now central bankers are trying to squeeze the excesses out of the system using a combination of higher interest rates and Quantitative Tightening.

After central bankers brought about recessions in the past, the world economy was able to recover by adding more energy supply. However, this time we are dealing with a situation of true depletion; there is no good way to recover by adding more energy supplies to the system. Instead, the only way the world economy can recover, at least partially, is by squeezing some non-essential energy uses out of the system. Hopefully, this can be done in such a way that a substantial part of the world economy can continue to operate in a manner close to that in the past.

One approach to making the economy more efficient in its energy use is by greater regionalization. If countries can start trading almost entirely with nearby neighbors, this will reduce the world’s energy consumption…

The economy is moving from a tailwind pushing it along to a headwind holding it back

The economy is moving from a tailwind pushing it along to a headwind holding it back

The problem is hitting limits in the extraction of fossil fuels

We know that historically, many economies around the world have collapsed. We also know that there is a physics reason why this happens. Growing economies require a growing supply of energy to keep up with a growing population. At some point, the energy supply and other resource needs cannot grow rapidly enough to keep up with population growth. When this happens, economies tend to collapse.

In their book Secular Cycles, researchers Peter Turchin and Sergey Nefedov found that economies tend go through four distinct phases in each cycle, with each stage lasting for quite a few years:

Growth
Stagflation
Crisis
Inter-cycle

Based on my own analysis, the world economy was in the Growth Stage for much of the time between the Industrial Revolution and 1973. In late 1973, oil prices spiked, and the world was put on notice that the energy supply could not continue rising as rapidly as in the past. Between 1973 and 2018, the world economy was in the Stagflation Stage. Based on current data, the world economy seems to have entered the Crisis Stage about 2018. This is the reason for saying that headwinds are beginning to hold the economy back in the title of this article .

When the Crisis Stage occurs, there are fewer goods and services per capita to go around, so some participants in 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.

Today’s Energy Crisis Is Very Different from the Energy Crisis of 2005

November 18, 2022

Today’s Energy Crisis Is Very Different from the Energy Crisis of 2005

Back in 2005, the world economy was “humming along.” World growth in energy consumption per capita was rising at 2.3% per year in the 2001 to 2005 period. China had been added to the World Trade Organization in December 2001, ramping up its demand for all kinds of fossil fuels. There was also a bubble in the US housing market, brought on by low interest rates and loose underwriting standards.

Figure 1. World primary energy consumption per capita based on BP’s *2022 Statistical Review of World Energy*.

The problem in 2005, as now, was inflation in energy costs that was feeding through to inflation in general. Inflation in food prices was especially a problem. The Federal Reserve chose to fix the problem by raising the Federal Funds interest rate from 1.00% to 5.25% between June 30, 2004 and June 30, 2006.

Now, the world is facing a very different problem. High energy prices are again feeding over to food prices and to inflation in general. But the underlying trend in energy consumption is very different. The growth rate in world energy consumption per capita was 2.3% per year in the 2001 to 2005 period, but energy consumption per capita for the period 2017 to 2021 seems to be slightly shrinking at minus 0.4% per year. The world seems to already be on the edge of recession.

The Federal Reserve seems to be using a similar interest rate approach now, in very different circumstances. In this post, I will try to explain why I don’t think that this approach will produce the desired outcome.

[1] The 2004 to 2006 interest rate hikes didn’t lead to lower oil prices until after July 2008.

It is easiest to see the impact (or lack thereof) of rising interest rates by looking at average monthly world oil prices.

Ramping Up Renewables Can’t Provide Enough Heat Energy in Winter

September 24, 2022

Ramping Up Renewables Can’t Provide Enough Heat Energy in Winter

We usually don’t think about the wonderful service fossil fuels provide in terms of being a store of heat energy for winter, the time when there is a greater need for heat energy. Figure 1 shows dramatically how, in the US, the residential usage of heating fuels spikes during the winter months.

Figure 1. US residential use of energy, based on EIA data. The category “Natural Gas, etc.” includes all fuels bought directly by households and burned. This is primarily natural gas, but also includes small amounts of propane and diesel burned as heating oil. Wood chips or other commercial wood purchased to be burned is also in this category.

Solar energy is most abundantly available in the May-June-July period, making it a poor candidate for fixing the problem of the need for winter heat.

Figure 2. California solar electricity production by month through June 30, 2022, based on EIA data. Amounts are for utility scale and small scale solar combined.

In some ways, the lack of availability of fuels for winter is a canary in the coal mine regarding future energy shortages. People have been concerned about oil shortages, but winter fuel shortages are, in many ways, just as bad. They can result in people “freezing in the dark.”

In this post, I will look at some of the issues involved.

[1] Batteries are suitable for fine-tuning the precise time during a 24-hour period solar electricity is used. They cannot be scaled up to store solar energy from summer to winter.

In today’s world, batteries can be used to delay the use of solar electricity for at most a few hours. In exceptional situations, perhaps the holding period can be increased to a few days.

The world’s self-organizing economy can be expected to act strangely, as energy supplies deplete

The world’s self-organizing economy can be expected to act strangely, as energy supplies deplete

It is my view that when energy supply falls, it falls not because reserves “run out.” It falls because economies around the world cannot afford to purchase goods and services made with energy products and using energy products in their operation. It is really a price problem. Prices cannot be simultaneously high enough for oil producers (such as Russia and Saudi Arabia) to ramp up production and remain low enough for consumers around the world to buy the goods and services that they are accustomed to buying.

Figure 1. Chart showing average annual Brent-equivalent oil prices in 2021$ based on data from BP’s *2022 Statistical Review of World Energy*, together with bars showing periods when prices seemed to be favorable to producers.

We are now in a period of price conflict. Oil and other energy prices have remained too low for producers since at least mid-2014. At the same time, depletion of fossil fuels has led to higher costs of extraction. Often, the tax needs of governments of oil exporting countries are higher as well, leading to even higher required prices for producers if they are to continue to produce oil and raise their production. Thus, producers truly require higher prices.

Governments of countries affected by this inflation in price are quite disturbed: Higher prices for energy products mean higher prices for all goods and services. This makes citizens very unhappy because wages do not rise to compensate for this inflation. Prices today are high enough to cause significant inflation (about $107 per barrel for Brent oil (Europe) and $97 for WTI (US)), but still not high enough to satisfy the high-price needs of energy producers.

The world has a major crude oil problem; expect conflict ahead

The world has a major crude oil problem; expect conflict ahead

Media outlets tend to make it sound as if all our economic problems are temporary problems, related to Russia’s invasion of Ukraine. In fact, world crude oil production has been falling behind needed levels since 2019. This problem, by itself, encourages the world economy to contract in unexpected ways, including in the form of economic lockdowns and aggression between countries. This crude oil shortfall seems likely to become greater in the years ahead, pushing the world economy toward conflict and the elimination of inefficient players.

To me, crude oil production is of particular importance because this form of oil is especially useful. With refining, it can operate tractors used to cultivate crops, and it can operate trucks to bring food to stores to sell. With refining, it can be used to make jet fuel. It can also be refined to make fuel for earth moving equipment used in road building. In recent years, it has become common to publish “all liquids” amounts, which include liquid fuels such as ethanol and natural gas liquids. These fuels have uses when energy density is not important, but they do not operate the heavy machinery needed to maintain today’s economy.

In this post, I provide an overview of the crude oil situation as I see it. In my analysis, I utilize crude oil production data by the US Energy Information Agency (EIA) that has only recently become available for the full year of 2021. In some exhibits, I also make estimates for the first quarter of 2022 based on preliminary information for this period.

[1] World crude oil production grew marginally in 2021.

No one will win in the Russia-Ukraine conflict

March 29, 2022

No one will win in the Russia-Ukraine conflict

Most people have a preconceived notion that there will be a clear winner and loser from any war. In their view, the world economy will go on, much as before, after the war is “won” by one side or the other. In my view, we are basically dealing with a no-win situation. No matter what the outcome, the world economy will be worse off after the fighting stops.

The problem the world economy is up against is the depletion of many kinds of resources simultaneously. This depletion is made worse by rising population, meaning that the resources available need to provide an adequate living for an increasing number of world inhabitants. Because of depletion, the world economy is reaching a point where it can no longer grow in the way it has in the past. Inflation, food shortages and rolling blackouts are likely to become increasing problems in many parts of the world. Eventually, the population is likely to fall.

We are living in a world that is beginning to behave like the players scrambling for seats in a game of musical chairs. In each round of a musical chairs game, one chair is removed from the circle. The players in the game must walk around the outside of the circle. When the music stops, all the players scramble for the remaining chairs. Someone gets left out.

Figure 1. Circle of chairs arranged for a game of musical chairs. Source

In this post, I will try to explain some of the issues.

[1] In a world with inadequate resources relative to population, conflicts are likely to become increasingly common.

Limits to Green Energy Are Becoming Much Clearer

February 10, 2022

Limits to Green Energy Are Becoming Much Clearer

We have been told that intermittent electricity from wind and solar, perhaps along with hydroelectricity, can be the basis of a green economy. Things are increasingly not working out as planned, however. Natural gas or coal used for balancing the intermittent output of renewables is increasingly high-priced or not available. It is becoming clear that modelers who encouraged the view that a smooth transition to wind, solar, and hydroelectric is possible have missed some important points.

Let’s look at some of the issues:

[1] It is becoming clear that intermittent wind and solar cannot be counted on to provide adequate electricity supply when the electrical distribution system needs them.

Early modelers did not expect that the variability of wind and solar would be a huge problem. They seemed to believe that, with the use of enough intermittent renewables, their variability would cancel out. Alternatively, long transmission lines would allow enough transfer of electricity between locations to largely offset variability.

In practice, variability is still a major problem. For example, in the third quarter of 2021, weak winds were a significant contributor to Europe’s power crunch. Europe’s largest wind producers (Britain, Germany and France) produced only 14% of installed capacity during this period, compared with an average of 20% to 26% in previous years. No one had planned for this kind of three-month shortfall.

In 2021, China experienced dry, windless weather so that both its wind and hydroelectric power were low. The country found it needed to use rolling blackouts to deal with the situation. This led to traffic lights failing and many families needing to eat candle-lit dinners.
