Will China Bring an Energy-Debt Crisis?

Posted on by

It is easy for those of us in the West to overlook how important China has become to the world economy, and also the limits it is reaching. The two big areas in which China seems to be reaching limits are energy production and debt. Reaching either of these limits could eventually cause a collapse.

China is reaching energy production limits in a way few would have imagined. As long as coal and oil prices were rising, it made sense to keep drilling. Once fuel prices started dropping in 2014, it made sense to close unprofitable coal mines and oil wells. The thing that is striking is that the drop in prices corresponds to a slowdown in the wage growth of Chinese urban workers. Perhaps rapidly rising Chinese wages have been playing a significant role in maintaining high world “demand” (and thus prices) for energy products. Low Chinese wage growth thus seems to depress energy prices.

(Shown as Figure 5, below). China’s percentage growth in average urban wages. Values for 1999 based on China Statistical Yearbook data regarding the number of urban workers and their total wages. The percentage increase for 2016 was based on a Bloomberg Survey.

The debt situation has arisen because feedback loops in China are quite different from in the US. The economic system is set up in a way that tends to push the economy toward ever more growth in apartment buildings, energy installations, and factories. Feedbacks do indeed come from the centrally planned government, but they are not as immediate as feedbacks in the Western economic system. Thus, there is a tendency for a bubble of over-investment to grow. This bubble could collapse if interest rates rise, or if China reins in growing debt.

2017: The Year When the World Economy Starts Coming Apart

Posted on by

Some people would argue that 2016 was the year that the world economy started to come apart, with the passage of Brexit and the election of Donald Trump. Whether or not the “coming apart” process started in 2016, in my opinion we are going to see many more steps in this direction in 2017. Let me explain a few of the things I see.

[1] Many economies have collapsed in the past. The world economy is very close to the turning point where collapse starts in earnest.  

Figure 1

Figure 1

The history of previous civilizations rising and eventually collapsing is well documented.(See, for example, Secular Cycles.)

To start a new cycle, a group of people would find a new way of doing things that allowed more food and energy production (for instance, they might add irrigation, or cut down trees for more land for agriculture). For a while, the economy would expand, but eventually a mismatch would arise between resources and population. Either resources would fall too low (perhaps because of erosion or salt deposits in the soil), or population would rise too high relative to resources, or both.

Even as resources per capita began falling, economies would continue to have overhead expenses, such as the need to pay high-level officials and to fund armies. These overhead costs could not easily be reduced, and might, in fact, grow as the government attempted to work around problems. Collapse occurred because, as resources per capita fell (for example, farms shrank in size), the earnings of workers tended to fall. At the same time, the need for taxes to cover what I am calling overhead expenses tended to grow. Tax rates became too high for workers to earn an adequate living, net of taxes. In some cases, workers succumbed to epidemics because of poor diets. Or governments would collapse, from lack of adequate tax revenue to support them.

Our current economy seems to be following a similar pattern. We first used fossil fuels to allow the population to expand, starting about 1800. Things went fairly well until the 1970s, when oil prices started to spike. Several workarounds (globalization, lower interest rates, and more use of debt) allowed the economy to continue to grow. The period since 1970 might be considered a period of “stagflation.” Now the world economy is growing especially slowly. At the same time, we find ourselves with “overhead” that continues to grow (for example, payments to retirees, and repayment of debt with interest). The pattern of past civilizations suggests that our civilization could also collapse.

Historically, economies have taken many years to collapse; I show a range of 20 to 50 years in Figure 1. We really don’t know if collapse would take that long now. Today, we are dependent on an international financial system, an international trade system, electricity, and the availability of oil to make our vehicles operate. It would seem as if this time collapse could come much more quickly.

With the world economy this close to collapse, some individual countries are even closer to collapse. This is why we can expect to see sharp downturns in the fortunes of some countries. If contagion is not too much of a problem, other countries may continue to do fairly well, even as individual small countries fail.

[2] Figures to be released in 2017 and future years are likely to show that the peak in world coal consumption occurred in 2014. This is important, because it means that countries that depend heavily on coal, such as China and India, can expect to see much slower economic growth, and more financial difficulties.

Energy limits: Why we see rising wealth disparity and low prices

Posted on by

Last week, I gave a fairly wide-ranging presentation at the 2016 Biophysical Economics Conference called Complexity: The Connection Between Fossil Fuel EROI, Human Energy EROI, and Debt (pdf). In this post, I discuss the portion of the talk that explains several key issues:

  1. Why we are right now seeing so many problems with respect to wealth disparity and low commodity prices (Answer: World per capita energy consumption is already falling, and the energy/economy system needs to reflect this problem somehow.)
  2. Why the quest for growing technology leads to growing wealth disparity (Answer: The economy must be configured in more of a hierarchical pattern to support growing “complexity.” Growing complexity is the precursor to growing technology.)
  3. Why rising debt is an integral part of the energy/economy system (Answer: We could not pay workers for making long-lasting goods and services without using debt to “pull forward” the hoped-for benefit of these goods and services to the present, using debt and other equivalent approaches.)
  4. Why commodity prices can suddenly fall below the cost of production for a wide range of products (Answer: Prices of commodities depend to a significant extent on debt levels. A major problem is that when commodity prices rise, wages do not rise in a corresponding manner. Rising debt levels can mask the growing lack of affordability for a while, but eventually, debt levels cannot be raised sufficiently, and commodity prices fall too low.)
  5. The Brexit vote may be related to falling energy per capita in the UK. Given that this problem occurs in many countries, it may be increasingly difficult to keep the Eurozone and other similar international organizations together.
  6. My talk also touches on the topic of why a steady state economy is not possible, unless we can live like chimpanzees.

My analysis has as its premise that the economy behaves like other physical systems. It needs energy–and, in fact, growing energy–to operate. If the system does not get the energy it needs, it “rebalances” in a way that may not be to our liking. See my article, “The Physics of Energy and the Economy.”

An outline of my talk is shown as Slide 2, below. I will omit the EROI and Hubbert model portions of the presentation.   Continue reading →

China: Is peak coal part of its problem?

Posted on by

The world’s coal resources are clearly huge. How could China, or the world in total, reach peak coal in a timeframe that makes a difference?

If we look at China’s coal production and consumption in BP’s 2016 Statistical Review of World Energy (SRWE), this is what we see:

Figure 1. China's production and consumption of coal based on BP 2016 SRWE.

Figure 1. China’s production and consumption of coal based on BP 2016 SRWE.

Figure 2 shows that the quantities of other fuels are increasing in a pattern similar to past patterns. None of them is large enough to make a real difference in offsetting the loss of coal consumption. Renewables (really “other renewables”) include wind, solar, geothermal, and wood burned to produce electricity. This category is still tiny in comparison to coal.

Why would a country selectively decide to slow down the growth of the fuel that has made its current “boom” possible? Coal is generally cheaper than other fuels. The fact that China has a lot of low-cost coal, and can use it together with its cheap labor, has allowed China to manufacture goods very inexpensively, and thus be very competitive in world markets.

In my view, China really had no choice regarding the cutback in coal production–market forces were pushing for less production of goods, and this was playing out as lower commodity prices of many types, including coal, oil, and natural gas, plus many types of metals.

China is mostly self-sufficient in coal production, but it is a major importer of natural gas and oil. Lower oil and natural gas prices made imported fuels of these types more affordable, and thus encouraged more importing of these products. At the same time, lower coal prices made many of China’s mines unprofitable, leading to a need to cut back on production. Thus we see the rather bizarre result: consumption of the cheapest energy product (coal) is falling first. We will discuss this issue more later.
