S-curves and other paths

Also published at Resilience.org.

Oxford University economist Kate Raworth is getting a lot of good press for her recently released book Doughnut Economics: 7 Ways to Think Like a 21st Century Economist.

The book’s strengths are many, starting with the accessibility of Raworth’s prose. Whether she is discussing the changing faces of economic orthodoxy, the caricature that is homo economicus, or the importance of according non-monetized activities their proper recognition, Raworth keeps things admirably clear.

Doughnut Economics makes a great crash course in promising new approaches to economics. In Raworth’s own words, her work “draws on diverse schools of thought, such as complexity, ecological, feminist, institutional and behavioural economics.” Yet the integration of ecological economics into her framework is incomplete, leading to a frustratingly unimaginative concluding chapter on economic growth.

Laying the groundwork for that discussion of economic growth has resulted in an article about three times as long as most of my posts, so here is the ‘tl;dr’ version:

Continued exponential economic growth is impossible, but the S-curve of slowing growth followed by a steady state is not the only other alternative. If the goal is maintaining GDP at the highest possible level, then the S-curve is the best case scenario, but in today’s world that isn’t necessarily desirable or even possible.

The central metaphor

Full disclosure: for as long as I can remember, the doughnut has been my least favourite among refined-sugar-white-flour-and-grease confections. So try as I might to be unbiased, I was no doubt predisposed to react critically to Raworth’s title metaphor.

What is the Doughnut? As Raworth explains, the Doughnut is the picture that emerged when she sketched a “safe space” between the Social Foundation necessary for prosperity, and the Ecological Ceiling beyond which we should not go.

Source: Doughnut Economics, page 38

There are many good things to be said about this picture. It affords a prominent place to both the social factors and the ecological factors which are essential to prosperity, but which are omitted from many orthodox economic models. The picture also restores ethics, and the choosing of goals, to central roles in economics.

Particularly given Raworth’s extensive background in development economics, it is easy to understand the appeal of this diagram.

But I agree with Ugo Bardi (here and here) that there is no particular reason the diagram should be circular – Shortfall, Social Foundation, Safe and Just Space, Ecological Ceiling and Overshoot would have the same meaning if arranged in horizontal layers rather than in concentric circles.

From the standpoint of economic analysis, I find it unhelpful to include a range of quite dissimilar factors all at the same level in the centre of the diagram. A society could have adequate energy, water and food without having good housing and health care – but you couldn’t have good housing and health care without energy, water and food. So some of these factors are clearly preconditions for others.

Likewise, some of the factors in the centre of the diagram are clearly and directly related to “overshoot” in the outer ring, while others are not. Excessive consumption of energy, water, or food often leads to ecological overshoot, but you can’t say the same about “excessive” gender equality, political voice, or peace and justice.

Beyond these quibbles with the Doughnut diagram, I further agree with Bardi that a failure to incorporate biophysical economics is the major weakness of Doughnut Economics. In spite of her acknowledgment of the pioneering work of Herman Daly, and a brief but lucid discussion of the work of Robert Ayres and Benjamin Warr showing that fossil fuels have been critical for the past century’s GDP growth, Raworth does not include energy supply as a basic determining factor in economic development.

Economists as spin doctors

Raworth makes clear that key doctrines of economic orthodoxy often obscure rather than illuminate economic reality. Thus economists in rich countries extoll the virtues of free trade, though their own countries relied on protectionism to nurture their industrial base.

Likewise standard economic modeling starts with a reductionist “homo economicus” whose decisions are always based on rational pursuit of self-interest – even though behavioral science shows that real people are not consistently rational, and are motivated by co-operation as much as by self-interest. Various studies indicate, however, that economics students and professors show a greater-than-average degree of self-interest. And for those who are already wealthy but striving to become wealthier still, it is comforting to believe that everyone is similarly self-interested, and that their self-interest works to the good of all.

When considering a principle of mainstream economics, then, it makes sense to ask: what truths does this principle hide, and for whose benefit?

Unfortunately, when it comes to GDP growth as the accepted measure of a healthy economy, Raworth leaves out an important part of the story.

The concept of Gross Domestic Product has its roots in the 1930s, when statisticians were looking for ways to quantify economic activity, making temporal trends easier to discern. Simon Kuznets developed a way to calculate Gross National Product – the total of all income generated worldwide by US residents.

As Raworth stresses, Kuznets himself was clear that his national income tally was a very limited way of measuring an economy.

Emphasising that national income captured only the market value of goods and services produced in an economy, he pointed out that it therefore excluded the enormous value of goods and services produced by and for households, and by society in the course of daily life. … And since national income is a flow measure (recording only the amount of income generated each year), Kuznets saw that it needed to be complemented by a stock measure, accounting for the wealth from which it was generated ….” (Doughnut Economics, page 34; emphasis mine)

The distinction between flows and stocks is crucial. Imagine a simple agrarian nation which uses destructive farming methods to work its rich land. For a number of years it may earn increasingly high income – the flow – though its wealth-giving topsoil – the stock – is rapidly eroding. Is this country getting richer or poorer? Measured by GDP alone, this economy is healthy as long as current income grows; no matter that the topsoil, and future prospects, are blowing away in the wind.

In the years immediately preceding and following World War II, GDP became the primary measure of economic health, and it became political and economic orthodoxy that GDP should grow every year. (To date no western leader has ever campaigned by promising “In my first year I will increase GDP by 3%, in my second year by 2%, in my third year it will grow by 1%, and by my fourth year I will have tamed GDP growth to 0!”)

What truth does this reliance on GDP hide, and for whose benefit? The answers are fairly obvious, in my humble opinion: a myopic focus on GDP obscured the inevitability of resource depletion, for the benefit of the fossil fuel and automative interests who dominated the US economy in the mid-twentieth century.

For context, in 1955 the top ten US corporations by number of employees included: General Motors, Chrysler, Standard Oil of New Jersey, Amoco, Goodyear and Firestone. (Source: 24/7 Wall St)

In 1960, the top ten largest US companies by revenue included General Motors, Exxon, Ford, Mobil, Gulf Oil, Texaco, and Chrysler. (Fortune 500)

These companies, plus the steel companies that made sheet metal for cars and the construction interests building the rapidly-growing network of roads, were clear beneficiaries of a new way of life that consumed ever-greater quantities of fossil fuels.

In the decades after World War II, the US industrial complex threw its efforts into rapid exploitation of energy reserves, along with mass production of machines that would burn that energy as fast as it could be pulled out of the ground. This transformation was not a simple result of “the invisible hand of the free market”; it relied on the enthusiastic collaboration of every level of government, from local zoning boards, to metropolitan transit authorities, to state and federal transportation planners.

But way back then, was it politically necessary to distract people from the inevitability of resource depletion?

The Peak Oil movement in the 1930s

From the very beginnings of the petroleum age, there were prominent voices who saw clearly that exponential growth in use of a finite commodity could not go on indefinitely.

One such voice was William Jevons, now known particularly for the “Jevons Paradox”. In 1865 he argued that since coal provided vastly more usable energy than industry had previously been able to harness, and since this new-found power was the very foundation of modern industrial civilization, it was particularly important to a nation to prudently manage supplies:

Describing the novel social experience that coal and steam power had created, the experience that today we would call ‘exponential growth’, in which practically infinite values are reached in finite time, Jevons showed how quickly even very large stores of coal might be depleted.” (Timothy Mitchell, Carbon Democracy, pg 129)

In the 1920s petroleum was the new miracle energy source, but thoughtful geologists and economists alike realized that as a finite commodity, petroleum could not fuel infinite growth.

Marion King Hubbert was a student in 1926, but more than sixty years later he still recalled the eye-opening lesson he received when a professor asked pupils to consider the implications of ongoing rapid increases in the consumption of coal and oil resources.

As Mason Inman relates in his excellent biography of Hubbert,

When a quantity grows by a constant percentage each year, its history forms a straight line on a semilogarithmic graph. Hubbert plotted the points for coal, year after year, and found a fairly straight line that persisted for several decades: a continual growth rate of around 6 percent a year. At that rate, the production doubled about every dozen years. When he looked at this graph, it was obvious to him that such rapid growth could persist for decades – his graph showed that had already happened – but couldn’t continue forever.” (The Oracle of Oil, 2016, pg 19)

Hubbert soon learned that there were many others who shared his concerns. This thinking coalesced in the 1930s in a very popular movement known as Technocracy. They argued that wealth depended primarily not on the circulation of money, but on the flow of energy.

The leaders of Technocracy, including Hubbert, were soon speaking to packed houses and were featured in cover stories in leading magazines. Hubbert was also tasked with producing a study guide that interested people could work through at home.

In the years prior to the Great Depression, people had become accustomed to economic growth of about 5% per year. Hubbert wanted people to realize it made no sense to take that kind of growth for granted.

“It has come to be naively expected by our business men and their apologists, the economists, that such a rate of growth was somehow inherent in the industrial processes,” Hubbert wrote. But since Earth and its physical resources are finite, he said, infinite growth is an impossibility.

In short, Technocracy pointed out that the fossil fuel age was likely to be a flash in the pan, historically speaking – unless the nation’s fuel reserves were managed carefully by engineers who understood energy efficiency and depletion.

Without sensible accounting and allocation of the true sources of a nation’s wealth – its energy reserves – private corporations would rake in massive profits for a few decades and two or three generations of Americans might prosper, but in the longer term the nation would be “burning its capital”.

Full speed ahead

After the convulsions of the Depression and World War II, the US emerged with the same leading corporations in an even more dominant position. Now the US had control, or at least major influence, not only over rich domestic fossil fuel reserves, but also the much greater reserves in the Middle East. And as the world’s greatest military and financial power, they were in a position to set the terms of trade.

For fossil fuel corporations the major problem was that oil was temporarily too cheap. It came flowing out of wells so easily and in such quantity that it was often difficult to keep the price up. It was in their interests that economies consume oil at a faster rate than ever before, and that the rate of consumption would speed up each year.

Fortunately for these interests, a new theory of economics had emerged just in time.

In this new theory, economists should not worry about measuring the exhaustion of resources. In Timothy Mitchell’s words, “Economics became instead a science of money.”

The great thing about money supply was that, unlike water or land or oil, the quantity of money could grow exponentially forever. And as long as one didn’t look too far backwards or forwards, it was easy to imagine that energy resources would prove no barrier. After all, for several decades, the price of oil had been dropping.

So although increasing quantities of energy were consumed, the cost of energy did not appear to represent a limit to economic growth. … Oil could be treated as something inexhaustible. Its cost included no calculation for the exhaustion of reserves. The growth of the economy, measured in terms of GNP, had no need to account for the depletion of energy resources.” (Carbon Democracy, pg 140)

GDP was thus installed as the supreme measure of an economy, with continuous GDP growth the unquestionable political goal.

A few voices dissented, of course. Hubbert warned in the mid-1950s that the US would hit the peak of its conventional fossil fuel production by the early 1970s, a prediction that proved correct. But large quantities of cheap oil remained in the Middle East. Additional new finds in Alaska and the North Sea helped to buy another couple of decades for the oil economy (though these fields are also now in decline).

Thanks to the persistent work of a small number of researchers who called themselves “ecological economists”, a movement grew to account for stocks of resources, in addition to tallying income flows in the GDP. By the early 1990s, the US Bureau of Economic Analysis gave its blessing to this effort.

In April 1994 the Bureau published a first set of tables called Integrated Environmental-Economic System of Accounts (IEESA).

The official effort was short-lived indeed. As described in Beyond GDP,

progress toward integrated environmental-economic accounting in the US came to a screeching halt immediately after the first IEESA tables were published. The US Congress responded swiftly and negatively. The House report that accompanied the next appropriations bill explicitly forbade the BEA from spending any additional resources to develop or extend the integrated environmental and economic accounting methodology ….” (Beyond GDP, by Heun, Carbajales-Dale, Haney and Roselius, 2016)

All the way through Fiscal Year 2002, appropriations bills made sure this outbreak of ecological economics was nipped in the bud. The bills stated,

The Committee continues the prohibition on use of funds under this appropriation, or under the Census Bureau appropriation accounts, to carry out the Integrated Environmental-Economic Accounting or ‘Green GDP’ initiative.” (quoted in Beyond GDP)

One can only guess that, when it came to contributing to Congressional campaign funds, the struggling fossil fuel interests had somehow managed to outspend the deep-pocketed biophysical economists lobby.

S-curves and other paths

With that lengthy detour complete, we are ready to rejoin Raworth and Doughnut Economics.

The final chapter is entitled “Be Agnostic About Growth: from growth addicted to growth agnostic”.

This sounds like a significant improvement over current economic orthodoxy – but I found this section weak in several ways.

First, it is unclear just what it is that we are to be agnostic about. While Raworth has made clear earlier in the book why GDP is an incomplete and misleading measure of an economy, in the final chapter GDP growth is nevertheless used as the only significant measure of economic growth. Are we to be agnostic about “GDP growth”, which might well be meaningless anyway? Or should we be agnostic about “economic growth”, which might be something quite different and quite a bit more essential – especially to the hundreds of millions of people still living without basic necessities?

Second, Raworth may be agnostic about growth, but she is not agnostic about degrowth. (She has discussed elsewhere why she can’t bring herself to use the word “degrowth”.) True, she remarks at one point that “I mean agnostic in the sense of designing an economy that promotes human prosperity whether GDP is going up, down, or holding steady.” Yet in the pictures she draws and in the ensuing discussion, there is no clear recognition either that degrowth might be desirable, or that degrowth might be forced on us by biophysical realities.

She includes two graphs for possible paths of economic growth –  with growth measured here simply by GDP.

Source: Doughnut Economics, page 210 and page 214

As she notes, the first graph shows GDP increasing at steady annual percentage. While the politicians would like us to believe this is possible and desirable, the graph showing what quickly becomes a near-vertical climb is seldom presented in economics textbooks, as it is clearly unrealistic.

The second graph shows GDP growing slowly at first, then picking up speed, and then leveling off into a high but steady state with no further growth. This path for growth is commonly seen and recognized in ecology. The S-curve was also recognized by pre-20th-century economists, including Adam Smith and John Stuart Mill, as the ideal for a healthy economy.

I would concur that an S-curve which lands smoothly on a high plateau is an ideal outcome. But can we take for granted that this outcome is still possible? And do these two paths – continued exponential growth or an S-curve – really exhaust the conceptual possibilities that we should consider?

On the contrary, we can look back 80 years to the Technocracy Study Course for an illustration of varied and contrasting paths of economic growth and degrowth.

Source: The Oracle of Oil, page 58

M. King Hubbert produced this set of graphs to illustrate what can be expected with various key commodities on which a modern industrial economy depends – and by extension, what might happen with the economy as a whole.

While pure exponential growth is impossible, the S-curve may work for a dependably renewable resource, or a renewable-resource based economy. However, the next possibility – with a rise, peak, decline, and then a leveling off – is also a common scenario. For example, a society may harvest increasing amounts of wood until the regenerating power of the forests are exceeded; the harvest must then drop before any production plateau can be established.

The bell curve which starts at zero, climbs to a high peak, and drops back to zero, could characterize an economy which is purely based on a non-renewable resource such as fossils fuels. Hopefully this “decline to zero” will remain a theoretical conception, since no society to date has run 100% on a non-renewable resource. Nevertheless our fossil-fuel-based industrial society will face a severe decline unless we can build a new energy system on a global scale, in very short order.

This range of economic decline scenarios is not really represented in Doughnut Economics. That may have something to do with the design of the title metaphor.

While ecological overshoot, on the outside of the doughnut, represents things we should not do, the diagram doesn’t have a way of representing the things we can not do.

We should not continue to burn large quantities of fossil fuel because that will destabilize the climate that our children and grandchildren inherit. But once our cheaply accessible fossil fuels are used up, then we can not consume energy at the same frenetic pace that today’s wealthy populations take for granted.

The same principle applies to many essential economic resources. As long as there is significant fertility left in farmland, we can choose to farm the land with methods that produce a high annual return even though they gradually strip away the topsoil. But once the topsoil is badly depleted, then we no longer have a choice to continue production at the same level – we simply need to take the time to let the land recover.

In other words, these biophysical realities are more fundamental than any choices we can make – they set hard limits on which choices remain open to us.

The S-curve economy may be the best-case scenario, an outcome which could in principle provide global prosperity with a minimum of system disruption. But with each passing year during which our economy is based overwhelmingly on rapidly depleting non-renewable resources, the smooth S-curve becomes a less likely outcome.

If some degree of economic decline is unavoidable, then clear-sighted planning for that decline can help us make the transition a just and peaceful one.

If we really want to think like 21st century economists, don’t we need to openly face the possibility of economic decline?

Guns, energy, and the coin of the realm

While US debt climbs to incomprehensible heights, US banking authorities continue to pump new money into the economy. How can they do it? David Graeber sees a  simple explanation:

There’s a reason why the wizard has such a strange capacity to create money out of nothing. Behind him, there’s a man with a gun.” (Debt: The First 5,000 Years, Melville House, 2013, pg 364)

In part one of this series, we looked at the extent of violence in the “American Century” – the period since World War II in which the US has been the number one superpower, and in which US garrisons have ringed the world. In part two we looked at the role of energy supplies in propelling the US to power, the rapid drawdown of energy supplies in the US post-WWII, and the more recent explosion of US debt.

In this concluding installment we’ll look at the links between military power and financial power.

A new set of financial institutions arose at the end of World War II, and for obvious reasons the US was ‘first among equals’ in setting the rules. Not only was the US in military occupation of Germany and Japan, but the US also had the financial capital to help shattered countries –whether on the war’s winning or losing sides – in reconstructing their infrastructures and restarting their economies.

The US was also able to offer military protection to many countries including previous mortal enemies. This meant that these countries could avoid large military outlays – but also that their elites were in no position to challenge US supremacy.

That being said, there were challenges both large and small in dozens of nations, particularly from the grass roots. The US exercised political power, both soft and hard, in attempts to influence the directions of scores of countries around the world. Planting of media reports, surreptitious aid to favoured electoral candidates, dirty tricks to discredit candidates seen as threatening, military aid and training to dictatorships and police forces who could put down movements for social justice, planning and helping to implement coups, and full-fledged military invasion – this range of intervention techniques resulted in hundreds of thousands, if not millions, of deaths. Cataloguing the bloody side of US “leadership of the free world” is the task taken on so ably by John Dower in The Violent American Century.

Dollars for oil

One of the rules of the game grew in importance with each passing decade. In Timothy Mitchell’s words,

Under the arrangements that governed the international oil trade, the commodity was sold in the currency not of the country where it was produced, nor of the place where it was consumed, but of the international companies that controlled production. ‘Sterling oil’, as it was known (principally oil from Iran), was traded in British pounds, but the bulk of global sales were in ‘dollar oil’.” (Carbon Democracy, Verso, 2013, pg 111)

As David Graeber’s Debt explains in detail, the ability to force people to acquire and use the ruler’s currency has, throughout history, been a key mechanism for extracting tribute from subject populations.

In today’s global economy, that is why the pricing of oil in dollars has been so important for the US. Again in Timothy Mitchell’s words:

Europe and other regions had to accumulate dollars, hold them and then return them to the United States in payment for oil. Inflation in the United States slowly eroded the value of the dollar, so that when these countries purchased oil, the dollars they used were worth less than their value when they acquired them. These seigniorage privileges, as they are called, enabled Washington to extract a tax from every other country in the world …. (Carbon Democracy, pg 120)

As Greg Grandin explains, the oil-US dollar relationship grew in importance even as OPEC countries were able to force big price increases:

With every rise in the price of oil, oil-importing countries had to borrow more to meet their energy needs. With every petrodollar placed in New York banks, the value of the US currency increased, and with it the value of the dollar-denominated debt that poor countries owed to those banks.” (“Down From The Mountain”, London Review of Books, June 19, 2017)

But the process did take on another important twist after US domestic oil production peaked and imports from Saudi Arabia soared in the 1970s. Although the oil trade continued to support the value of the US dollar, the US was now sending a lot more of those dollars to oil exporting countries. The Saudis, in particular, accumulated US dollars so fast there wasn’t a productive way for them to circulate these dollars back into the US by purchasing US-made goods. The burgeoning US exports of munitions provided a solution. Mitchell explains:

As the producer states gradually forced the major oil companies to share with them more of the profits from oil, increasing quantities of sterling and dollars flowed to the Middle East. To maintain the balance of payments and the viability of the international financial system, Britain and the United States needed a mechanism for these currency flows to be returned. … Arms were particularly suited to this task of financial recycling, for their acquisition was not limited by their usefulness. The dovetailing of the production of petroleum and the manufacture of arms made oil and militarism increasingly interdependent.” (Carbon Democracy, pg 155-156)

He adds, “The real value of US arms exports more than doubled between 1967 and 1975, with most of the new market in the Middle East.”

Fast forward to today. Imported oil is a critical factor in the US economy, in spite of a supply blip from fracking. US industry leads the world in the export of weapons; the top three buyers, and five of the top ten buyers, are in the Middle East. (Source: CNN, May 25, 2016) Yet US arms sales are dwarfed by US military expenditures, which are roughly double in real terms what they were in the 1960s. (Source: Time, July 16, 2013)

Finally, US national debt, in 1983 dollars, is about 10 times as high as it was from 1950 to 1980. In other words the US government, along with its banking and military complexes, has been living far beyond its means (making bankruptcy king Donald Trump a fitting figurehead). (Source: Stephen Bloch, Adelphi University)

Yet the game goes on. As David Graeber sees it,

American imperial power is based on a debt that will never – can never – be repaid. Its national debt has become a promise, not just to its own people, but to the nations of the entire world, that everyone knows will not be kept.

At the same time, U.S. policy was to insist that those countries relying on U.S. treasury bonds as their reserve currency behaved in exactly the opposite way: observing tight money policies and scrupulously repaying their debts ….” (Debt, pg 367)

We’ll close with two speculations on how the “American century” may come to an end.

US supremacy rests on interrelated dominance in military power, financial power, and influence over fossil fuel energy markets. At present the US financial system can create ever larger sums of money, and the rest of the world may have no immediately preferable options than to continue buying US debt. But just as you can’t eat money, you can’t burn it in an electricity generator, a diesel truck, or a bomber flying sorties to a distant land. So no amount of financial wizardry will sustain the current outsized industrial economy or its military subsection, once prime fossil fuel sources have been tapped out.

On the other hand, suppose low-carbon renewable energy technologies improve so rapidly that they can replace fossil fuels within a few decades. This would be a momentous energy transition, and might also lead to a momentous transition in geopolitics.

In recent years, and especially under the Trump administration, the US is ceding renewable energy technology leadership to other countries, especially China. If many countries free themselves from fossil-fuel dependence, and they no longer need US dollars to purchase their energy needs, a pillar of US supremacy will fall.

Fossil fuel empire: a world of vulnerability

Also published at Resilience.org.

“It’s all about the oil,” many commentators said about the US assault on Iraq in 2003.

Attributing a war to a single cause is almost always an oversimplification, but protecting access to the 20th century’s most important energy source has been a priority of US foreign policy since World War II.

In part one of this series we considered the effects of the US military complex which has ringed the world for the past 75 years. This complex has depended on vast amounts of fossil fuel energy to move troops and munitions, and the US became a world power in significant part because of its endowment of oil.

As Daniel Yergin recounts in The Prize: The Epic Quest for Oil, Money & Power

Petroleum was central to the course and outcome of World War II in both the Far East and Europe. The Japanese attacked Pearl Harbor to protect their flank as they grabbed for the petroleum resources of the East Indies. Among Hitler’s most important strategic objectives in the invasion of the Soviet Union was the capture of the oil fields in the Caucasus. But America’s predominance in oil proved decisive, and by the end of the war German and Japanese fuel tanks were empty.” (The Prize, Simon & Schuster, 1990, pg 13)

At the end of World War II the US was not only the world’s preeminent military force, but its industrial capacity was undamaged by war and it was running on seemingly abundant supplies of cheap domestic oil.

Spurred on by oil and car companies who had the most to gain from a high-energy way of life, the US embarked on a building spree of far-flung suburbs, interstate highways, and airports that allowed long-distance flight to become a routine activity.

This hyper-consumption was bolstered by a new economic orthodoxy which saw no need to factor in energy depletion when accounting for national wealth, and which portrayed exponential economic growth as a phenomenon that could and should continue decade after decade.

It took barely a generation, of course, for the US economy to suck up the bulk of its cheap domestic oil – conventional oil production peaked in the US in 1971. Did Americans then conclude they should change the basis of their economy, and make peace with reduced energy consumption? Far from it. Dependence on imported oil has now been a central feature of the US economy for fifty years.

A world of vulnerability

The huge military complex which protects essential oil supply routes is sometimes seen as a sign of US strength, but it can just as accurately be seen as a sign of US weakness.

In a 2009 report entitled “Powering America’s Defense: Energy and the Risks to National Security”, a panel of twelve retired generals and admirals notes that “The U.S. consumes 25 percent of the world’s oil production, yet controls less than 3 percent of an increasingly tight supply.” This voracious appetite for oil, they say, is a dangerous vulnerability:

As we consider America’s current energy posture, we do so from a singular perspective: We gauge our energy choices solely by their impact on America’s national security. Our dependence on foreign oil reduces our international leverage, places our troops in dangerous global regions, funds nations and individuals who wish us harm, and weakens our economy; our dependency and inefficient use of oil also puts our troops at risk.” (Introduction to Powering America’s Defense)

One source of imported oil has outranked all others for the US and its western European allies. The US was already consolidating its “special relationship” with Saudi Arabia in the 1930s, in the first years of that country’s existence. As Timothy Mitchell describes this relationship,

Aramco [Arabian-American Oil Company] paid the oil royalty not to a national government but to a single household, that of Ibn Saud, who now called himself king and renamed the country … the ‘Kingdom of Saudi Arabia’. … This ‘privatisation’ of oil money was locally unpopular, and required outside help to keep it in place. In 1945 the US government established its military base at Dhahran, and later began to train and arm Ibn Saud’s security forces …. The religious establishment, on the other hand, created the moral and legal order of the new state, imposing the strict social regime that maintained discipline in the subject population and suppressed political dissent.” (Timothy Mitchell, Carbon Democracy, Verso, 2013, pg 210-211)

The alliance between a self-styled liberal democracy and an theocratic autocracy has not been a marriage made in heaven. But in spite of many points of tension the relationship has benefited powerful forces in both countries and has endured for most of the age of oil.

The need to protect US access to the world’s largest sources of conventional oil was formally recognized in the Carter Doctrine:

An attempt by any outside force to gain control of the Persian Gulf region will be regarded as an assault on the vital interests of the United States of America, and such an assault will be repelled by any means necessary, including military force.” (US President Jimmy Carter in his State of the Union Address, January 1980)

Ironically, this doctrine led the US to begin supporting the mujahideen, Islamic fundamentalists who were fighting the Soviet Union in Afghanistan. And ironically, after the Soviet-Afghan war ended one of the major irritants for the formerly lauded “freedom fighters” was the heavy military presence of the infidel United States in Saudi Arabia. The result has been almost 20 years of continuous warfare between the US and various offshoots of the mujahideen, with no prospect of victory for the US.

The costs of these wars, merely in dollar terms, have been staggering. While US military expenditures have remained high ever since World War II, these costs have recently gone through the roof. An analysis of military spending by Time in 2013 found that inflation-adjusted military spending in the 2000s was approximately twice as high as military spending in the 1960s, during the nuclear face-off with Russia and the massive deployment in Indochina.

In sum, the US has been importing increasing quantities of increasingly expensive oil for decades. During the same years US military spending has soared. Does this sound like a recipe for solvency? You might well wonder if it’s just coincidence that US national debt has soared during these years.

US national debt converted to 1983 dollars and plotted on logarithmic scale – each step up the ladder is 10 times as high as the previous step – by Stephen Bloch of Adelphi University.

 

Recall the curious formulation by John Dower cited in the first installment of this series:

Creating a capacity for violence greater than the world has ever seen is costly – and remunerative.” (The Violent American Century, pg 12, emphasis mine)

How is this world-wide military occupation remunerative? In our next installment we’ll look at the tie-in between the power that grows out of the barrel of a gun, and the power that comes with control of currency.

The stratospheric costs of The American Century

“Political power grows out of the barrel of a gun,” Chairman Mao famously stated in 1927.

Political power grows out of a barrel of oil – that’s an important theme in Daniel Yergin’s classic book The Prize: The Epic Quest for Oil, Money & Power.

Political power, including the use of state violence, goes hand in hand with control of authorized currency – that’s one of the key lessons of David Graeber’s Debt: The First 5,000 Years.

Guns, energy, money – each of these factors of power comes to mind in reading the recently released book by John Dower, The Violent American Century: War And Terror Since World War Two. (Chicago, Haymarket Books, 2017)

This brief book keeps a tight focus: cataloguing the extent of violence associated with the US role as the world’s dominant superpower. Dower avoids many closely related questions, such as Which persons or sectors in the US benefit most from military conflict? or, Was there justification for any of the violent overseas adventures by US forces in the past 75 years? or, Might the world have been more, or less, violent if the US had not been the dominant superpower?

It may be easy to forget, in Canada or western Europe or especially in the United States, that wars big and small have been raging somewhere in the world nearly every year through our lifetimes. Dower’s book is prompted in part by the recently popularized notion that on a world historical scale, violence is recently at an all-time low. Stephen Pinker, in his 2011 book The Better Angels of Our Nature, marshaled both statistics and anecdotes to advance the view that “today we may be living in the most peaceable era in our species’ existence.”

Dower doesn’t try to definitively refute the idea of a “Long Peace”, but he does ask us to question widely held assumptions.

He begins with the important point that if you start with the unprecedented mass slaughter of World War II as a baseline, it’s easy to make a case that succeeding decades have been relatively peaceful.

Yet one of the key military strategies used by the US in World War II was retained in both practice and theory by subsequent US warlords – aerial bombardment of civilian populations.

By the time the United States began carpet-bombing Japan, ‘industrial war’ and psychological warfare were firmly wedded, and the destruction of enemy morale by deliberately targeting densely populated urban centers had become standard operating procedure. US air forces would later carry this most brutal of inheritances from World War Two to the populations of Korea and Indochina.” (The Violent American Century, pg 22)

The result of this policy carry-over was that

During the Korean War … the tonnage of bombs dropped by US forces was more than four times greater than had been dropped on Japan in 1945. … In the Vietnam War … an intensive US bombing campaign that eventually extended to Cambodia and Laos dropped more than forty times the tonnage of bombs used on Japan.” (The Violent American Century, pg 43)

The massive bombardments failed to produce unambiguous victories in Korea or in Indochina, but it’s hard to look at these wars and avoid the conclusion that the scope and scale of violence had remained terribly high.

Meanwhile US war planners were preparing for destruction on an even greater scale. Both US and Soviet nuclear forces held the capability of destroying all human life – and yet they continued to build more nuclear missiles and continued to discuss whether they would ever launch a first strike.

By the time of his retirement, former Strategic Air Command director General (George) Lee Butler had become an advocate of nuclear abolition. In his insider’s view, “mankind escaped the Cold War without a nuclear holocaust by some combination of diplomatic skill, blind luck and divine intervention, probably the latter in greatest proportion.”

Yet the danger remains. Even Nobel Peace Prize winner Barack Obama, who stirred hopes for peace in 2009 by calling for abolition of nuclear weapons, left office having approved a $1 trillion, 30-year program of upgrading US nuclear weapons.

Though the Cold War ended without conflagration between the world’s major powers, a CIA tabulation listed 331 “Major Episodes of Political Violence” between 1946 and 2013. The US armed, financed and/or coached at least one side in scores of these conflicts, and participated more directly in dozens. This history leads Dower to conclude

Branding the long postwar era as an epoch of relative peace is disingenuous …. It also obscures the degree to which the United States bears responsibility for contributing to, rather than impeding, militarization and mayhem after 1945.” (The Violent American Century, pg 3)

Dower also notes that violence doesn’t always end in death – sometimes it leads to flight. In this regard the recent, rapid increase in numbers of refugees calls into question the idea of a new era of peace. The United Nations High Commissioner for Refugees recently reported that the number of forcibly displaced individuals “had surpassed sixty million and was the highest level recorded since World War Two and its immediate aftermath.”

The wages of war

Since the US victory in World War II, the nation has responded by building an ever larger, ever more extensive military presence around the world. By the early 2000s, according to former CIA consultant Chalmers Johnson, the US owned or rented more than 700 military bases in 130 countries.

Dower gives a brief tally of the financial costs to the US of this military occupation of the globe. In addition to the “base” defense department budget of about $600 billion per year, Dower says many extra expenses include “contingency” costs of engagements in the Middle East, care for veterans, the “black budget” for the CIA, and interest on the military component of the national debt, pushing the cost of the US military complex to around $1 trillion per year.

He concludes, “Creating a capacity for violence greater than the world has ever seen is costly – and remunerative.”

In coming installments of this essay we’ll consider especially those last three words: “costly and remunerative”. Who pays for and who benefits from the massive maintenance and exercise of military muscle, and over what time scale? In doing so, we’ll explore the interrelationships of three types of power: power from the barrel of a gun, power that comes from a barrel of oil, and power that comes from control of the monetary system.

Energy And Civilization: a review

Also published at Resilience.org and BiophysEco.

If you were to find yourself huddled with a small group of people in a post-crash, post-internet world, hoping to recreate some of the comforts of civilization, you’d do well to have saved a printed copy of Vaclav Smil’s Energy and Civilization: A History.

Smil’s new 550-page magnum opus would help you understand why for most applications a draft horse is a more efficient engine than an ox – but only if you utilize an effective harness, which is well illustrated. He could help you decide whether building a canal or a hard-topped road would be a more productive use of your energies. When you were ready to build capstans or block-and-tackle mechanisms for accomplishing heavy tasks, his discussion and his illustrations would be invaluable.

But hold those thoughts of apocalypse for a moment. Smil’s book is not written as a doomer’s handbook, but as a thorough guide to the role of energy conversions in human history to date. Based on his 1994 book Energy in World History, the new book is about 60% longer and includes 40% more illustrations.

Though the initial chapters on prehistory are understandably brief, Smil lays the groundwork with his discussion of the dependency of all living organisms on their ability to acquire enough energy in usable forms.

The earliest humanoids had some distinct advantages and liabilities in this regard. Unlike other primates, humans evolved to walk on two feet all the time, not just occasionally. Ungainly though this “sequence of arrested falls” may be, “human walking costs about 75% less energy than both quadrupedal and bipedal walking in chimpanzees.” (Energy and Civilization, pg 22)

What to do with all that saved energy? Just think:

The human brain claims 20–25% of resting metabolic energy, compared to 8–10% in other primates and just 3–5% in other mammals.” (Energy and Civilization, pg 23)

In his discussion of the earliest agricultures, a recurring theme is brought forward: energy availability is always a limiting factor, but other social factors also come into play throughout history. In one sense, Smil explains, the move from foraging to farming was a step backwards:

Net energy returns of early farming were often inferior to those of earlier or concurrent foraging activities. Compared to foraging, early farming usually required higher human energy inputs – but it could support higher population densities and provide a more reliable food supply.” (Energy and Civilization, pg 42)

The higher population densities allowed a significant number of people to work at tasks not immediately connected to securing daily energy requirements. The result, over many millennia, was the development of new materials, tools and processes.

Smil gives succinct explanations of why the smelting of brass and bronze was less energy-intensive than production of pure copper. Likewise he illustrates why the iron age, with its much higher energy requirements, resulted in widespread deforestation, and iron production was necessarily very limited until humans learned to exploit coal deposits in the most recent centuries.

Cooking snails in a pot over an open fire. In Energy and Civilization, Smil covers topics as diverse as the importance of learning to use fire to supply the energy-rich foods humans need; the gradual deployment of better sails which allowed mariners to sail closer to the wind; and the huge boost in information consumption that occurred a century ago due to a sudden drop in the energy cost of printing.

Energy explosion

The past two hundred years of fossil-fuel-powered civilization takes up the biggest chunk of the book. But the effective use of fossil fuels had to be preceded by many centuries of development in metallurgy, chemistry, understanding of electromagnetism, and a wide array of associated technologies.

While making clear how drastically human civilizations have changed in the last several generations, Smil also takes care to point out that even the most recent energy transitions didn’t take place all at once.

While the railways were taking over long-distance shipments and travel, the horse-drawn transport of goods and people dominated in all rapidly growing cities of Europe and North America.” (Energy and Civilization, pg 185)

Likewise the switches from wood to coal or from coal to oil happened only with long overlaps:

The two common impressions – that the twentieth century was dominated by oil, much as the nineteenth century was dominated by coal – are both wrong: wood was the most important fuel before 1900 and, taken as a whole, the twentieth century was still dominated by coal. My best calculations show coal about 15% ahead of crude oil …” (Energy and Civilization, pg 275)

Smil draws an important lesson for the future from his careful examination of the past:

Every transition to a new form of energy supply has to be powered by the intensive deployment of existing energies and prime movers: the transition from wood to coal had to be energized by human muscles, coal combustion powered the development of oil, and … today’s solar photovoltaic cells and wind turbines are embodiments of fossil energies required to smelt the requisite metals, synthesize the needed plastics, and process other materials requiring high energy inputs.” (Energy and Civilization, pg 230)

A missing chapter

Energy and Civilization is a very ambitious book, covering a wide spread of history and science with clarity. But a significant omission is any discussion of the role of slavery or colonialism in the rise of western Europe.

Smil does note the extensive exploitation of slave energy in ancient construction works, and slave energy in rowing the war ships of the democratic cities in ancient Greece. He carefully calculates the power output needed for these projects, whether supplied by slaves, peasants, or animals.

In his look at recent European economies, Smil also notes the extensive use of physical and child labour that occurred simultaneously with the growth of fossil-fueled industry. For example, he describes the brutal work conditions endured by women and girls who carried coal up long ladders from Scottish coal mines, in the period before effective machinery was developed for this purpose.

But what of the 20 million or more slaves taken from Africa to work in the European colonies of the “New World”? Did the collected energies of all these unwilling participants play no notable role in the progress of European economies?

Likewise, vast quantities of resources in the Americas, including oil-rich marine mammals and old-growth forests, were exploited by the colonies for the benefit of European nations which had run short of these important energy commodities. Did this sudden influx of energy wealth play a role in European supremacy over the past few centuries? Attention to such questions would have made Energy and Civilization a more complete look at our history.

An uncertain future

Smil closes the book with a well-composed rumination on our current predicaments and the energy constraints on our future.

While the timing of transition is uncertain, Smil leaves little doubt that a shift away from fossil fuels is necessary, inevitable, and very difficult. Necessary, because fossil fuel consumption is rapidly destabilizing our climate. Inevitable, because fossil fuel reserves are being depleted and will not regenerate in any relevant timeframe. Difficult, both because our industrial economies are based on a steady growth in consumption, and because much of the global population still doesn’t have access to a sufficient quantity of energy to provide even the basic necessities for a healthy life.

The change, then, should be led by those who are now consuming quantities of energy far beyond the level where this consumption furthers human development.

Average per capita energy consumption and the human development index in 2010. Smil, Energy and Civilization, pg 363

 

Smil notes that energy consumption rises in correlation with the Human Development Index up to a point. But increases in energy use beyond, roughly the level of present-day Turkey or Italy, provide no significant boost in Human Development. Some of the ways we consume a lot of energy, he argues, are pointless, wasteful and ineffective.

In affluent countries, he concludes,

Growing energy use cannot be equated with effective adaptations and we should be able to stop and even to reverse that trend …. Indeed, high energy use by itself does not guarantee anything except greater environmental burdens.

Opportunities for a grand transition to less energy-intensive society can be found primarily among the world’s preeminent abusers of energy and materials in Western Europe, North America, and Japan. Many of these savings could be surprisingly easy to realize.” (Energy and Civilization, pg 439)

Smil’s book would indeed be a helpful post-crash guide – but it would be much better if we heed the lessons, and save the valuable aspects of civilization, before apocalypse overtakes us.

The Carbon Code – imperfect answers to impossible questions

Also published at Resilience.org.

“How can we reconcile our desire to save the planet from the worst effects of climate change with our dependence on the systems that cause it? How can we demand that industry and governments reduce their pollution, when ultimately we are the ones buying the polluting products and contributing to the emissions that harm our shared biosphere?”

These thorny questions are at the heart of Brett Favaro’s new book The Carbon Code (Johns Hopkins University Press, 2017). While he  readily concedes there can be no perfect answers, his book provides a helpful framework for working towards the immediate, ongoing carbon emission reductions that most of us already know are necessary.

Favaro’s proposals may sound modest, but his carbon code could play an important role if it is widely adopted by individuals, by civil organizations – churches, labour unions, universities – and by governments.

As a marine biologist at Newfoundland’s Memorial University, Favaro is keenly aware of the urgency of the problem. “Conservation is a frankly devastating field to be in,” he writes. “Much of what we do deals in quantifying how many species are declining or going extinct  ….”

He recognizes that it is too late to prevent climate catastrophe, but that doesn’t lessen the impetus to action:

There’s no getting around the prospect of droughts and resource wars, and the creation of climate refugees is certain. But there’s a big difference between a world afflicted by 2-degree warming and one warmed by 3, 4, or even more degrees.”

In other words, we can act now to prevent climate chaos going from worse to worst.

The code of conduct that Favaro presents is designed to help us be conscious of the carbon impacts of our own lives, and work steadily toward the goal of a nearly-complete cessation of carbon emissions.

The carbon code of conduct consists of four “R” principles that must be applied to one’s carbon usage:

1. Reduce your use of carbon as much as possible.

2. Replace carbon-intensive activities with those that use less carbon to achieve the same outcome.

3. Refine the activity to get the most benefit for each unit of carbon emitted.

4. Finally, Rehabilitate the atmosphere by offsetting carbon usage.”

There’s a good bit of wiggle room in each of those four ’R’s, and Favaro presents that flexibility not as a bug but as a feature. “Codes of conduct are not the same thing as laws – laws are dichotomous, and you are either following them or you’re not,” he says. “Codes of conduct are interpretable and general and are designed to shape expectations.”

Street level

The bulk of the book is given to discussion of how we can apply the carbon code to home energy use, day-to-day transportation, a lower-carbon diet, and long distance travel.

There is a heavy emphasis on a transition to electric cars – an emphasis that I’d say is one of the book’s weaker points. For one thing, Favaro overstates the energy efficiency of electric vehicles.

EVs are far more efficient. Whereas only around 20% of the potential energy stored in a liter of gasoline actually goes to making an ICE [Internal Combustion Engine] car move, EVs convert about 60% of their stored energy into motion ….”

In a narrow sense this is true, but it ignores the conversion costs in common methods of producing the electricity that charges the batteries. A typical fossil-fueled generating plant operates in the range of 35% energy efficiency. So the actual efficiency of an electric vehicle is likely to be closer to 35% X 60%, or 21% – in other words, not significantly better than the internal combustion engine.

By the same token, if a large proportion of new renewable energy capacity over the next 15 years must be devoted to charging electric cars, it will be extremely challenging to simultaneously switch home heating, lighting and cooling processes away from fossil fuel reliance.

Yet if the principles of Favaro’s carbon code were followed, we would not only stop building internal combustion cars, we would also make the new electric cars smaller and lighter, provide strong incentives to reduce the number of miles they travel (especially miles with only one passenger), and rapidly improve bicycling networks and public transit facilities to get people out of cars for most of their ordinary transportation. To his credit, Favaro recognizes the importance of all these steps.

Flight paths

As a researcher invited to many international conferences, and a person who lives in Newfoundland but whose family is based in far-away British Columbia, Favaro has given a lot of thought to the conundrum of air travel. He notes that most of the readers of his book will be members of a particular global elite: the small percentage of the world’s population who board a plane more than a few times in their lives.

We members of that elite group have a disproportionate carbon footprint, and therefore we bear particular responsibility for carbon emission reductions.

The Air Transport Action Group, a UK-based industry association, estimated that the airline industry accounts for about 2% of global CO2 emissions. That may sound small, but given the tiny percentage of the world population that flies regularly, it represents a massive outlier in terms of carbon-intensive behaviors. In the United States, air travel is responsible for about 8% of the country’s emissions ….”

Favaro is keenly aware that if the Carbon Code were read as “never get on an airplane again for the rest of your life”, hardly anyone would adopt the code (and those few who did would be ostracized from professional activities and in many cases cut off from family). Yet the four principles of the Carbon Code can be very helpful in deciding when, where and how often to use the most carbon-intensive means of transportation.

Remember that ultimately all of humanity needs to mostly stop using fossil fuels to achieve climate stability. Therefore, just like with your personal travel, your default assumption should be that no flights are necessary, and then from there you make the case for each flight you take.”

The Carbon Code is a wise, carefully optimistic book. Let’s hope it is widely read and that individuals and organizations take the Carbon Code to heart.

Being right, and being persuasive: a primer on ‘talking climate’

Also published at Resilience.org.

Given that most people in industrialized countries accept that climate change is a scientific reality, why do so few rank climate change as one of their high priorities? Why do so few people discuss climate change with their families, friends, and neighbours? Are clear explanations of the ‘big numbers’ of climate change a good foundation for public engagement?

These are among the key questions in a thought-provoking new book by Adam Corner and Jamie Clarke – Talking Climate: From Research to Practice in Public Engagement.

In a brief review of climate change as a public policy issue, Corner and Clarke make the point that climate change action was initially shaped by international responses to the ozone layer depletion and the problem of acid rain. In these cases technocrats in research, government and industry were able to frame the problem and implement solutions with little need for deep public engagement.

The same model might once have worked for climate change response. But today, we are faced with a situation where climate change will be an ongoing crisis for at least several generations. Corner and Clarke argue that responding to climate change will require public engagement that is both deep and broad.

That kind of engagement can only be built through wide-ranging public conversations which tap into people’s deepest values – and climate change communicators must learn from social science research on what works, and what doesn’t work, in growing a public consensus.

Talking Climate is at its best in explaining the limitations of dominant climate change communication threads. But the book is disappointingly weak in describing the ‘public conversations’ that the authors say are so important.

 


Narratives and numbers

“Stories – rather than scientific facts – are the vehicles with which to build public engagement”, Corner and Clarke say. But climate policy is most often framed by scientifically valid and scientifically important numbers which remain abstract to most people. In particular, the concept of a 2°C limit to overall global warming has received oceans of ink, and this concept was the key component of the 2015 Paris Agreement.

Unfortunately, the 2° warming threshold does not help move climate change from a ‘scientific reality’ to a ‘social reality’:

In research conducted just before the Paris negotiations with members of the UK public, we found that people were baffled by the 2 degrees concept and puzzled that the challenge of climate change would be expressed in such a way. … People understandably gauge temperature changes according to their everyday experiences, and a daily temperature fluctuation of 2 degrees is inconsequential, pleasant even – so why should they worry?

“Being right is not the same as being persuasive,” Corner and Clarke add, “and the ‘big numbers’ of the climate change and energy debate do not speak to the lived experience of ordinary people going about their daily lives ….”

While they cite interesting research on what doesn’t work in building public engagement, the book is frustratingly skimpy on what does work.

In particular, there are no good examples of the narratives or stories that the authors hold out as the primary way most people make sense of the world.

“Narratives have a setting, a plot (beginning, middle, and end), characters (heroes, villains, and victims), and a moral of the story,” Corner and Clarke write. How literally should we read that statement? What are some examples of stories that have emerged to help people understand climate change and link their responses to their deepest values? Unfortunately we’re left guessing.

Likewise, the authors write that they have been involved with several public consultation projects that helped build public engagement around climate change. How did these projects select or attract participants, given that only a small percentage of the population regards climate change as an issue of deep personal importance?

Talking Climate packs a lot of important research and valuable perspectives into a mere 125 pages, plus notes. Another 25 pages outlining successful communication efforts might have made it an even better book.

Fake news, failed states

Also published at Resilience.org.

Many of the violent conflicts raging today can only be understood if we look at the interplay between climate change, the shrinking of cheap energy supplies, and a dominant economic model that refuses to acknowledge physical limits.

That is the message of Failing States, Collapsing Systems: BioPhysical Triggers of Political Violence, a thought-provoking new book by Nafeez Mosaddeq Ahmed. Violent conflicts are likely to spread to all continents within the next 30 years, Ahmed says, unless a realistic understanding of economics takes hold at a grass-roots level and at a nation-state policy-making level.

The book is only 94 pages (plus an extensive and valuable bibliography), but the author packs in a coherent theoretical framework as well as lucid case studies of ten countries and regions.

As part of the Springer Briefs In Energy/Energy Analysis series edited by Charles Hall, it is no surprise that Failing States, Collapsing Systems builds on a solid grounding in biophysical economics. The first few chapters are fairly dense, as Ahmed explains his view of global political/economic structures as complex adaptive systems inescapably embedded in biophysical processes.

The adaptive functions of these systems, however, are failing due in part to what we might summarize with four-letter words: “fake news”.

inaccurate, misleading or partial knowledge bears a particularly central role in cognitive failures pertaining to the most powerful prevailing human political, economic and cultural structures, which is inhibiting the adaptive structural transformation urgently required to avert collapse.” (Failing States, Collapsing Systems: BioPhysical Triggers of Political Violence, by Nafeez Mosaddeq Ahmed, Springer, 2017, page 13)

We’ll return to the failures of our public information systems. But first let’s have a quick look at some of the case studies, in which the explanatory value of Ahmed’s complex systems model really comes through.

In discussing the rise of ISIS in the context war in Syria and Iraq, Western media tend to focus almost exclusively on political and religious divisions which are shoehorned into a “war on terror” framework. There is also an occasional mention of the early effects of climate change. While not discounting any of these factors, Ahmed says that it is also crucial to look at shrinking supplies of cheap energy.

Prior to the onset of war, the Syrian state was experiencing declining oil revenues, driven by the peak of its conventional oil production in 1996. Even before the war, the country’s rate of oil production had plummeted by nearly half, from a peak of just under 610,000 barrels per day (bpd) to approximately 385,000 bpd in 2010.” (Failing States, Collapsing Systems, page 48)

Similarly, Yemen’s oil production peaked in 2001, and had dropped more than 75% by 2014.

While these governments tried to cope with climate change effects including water and food shortages, their oil-export-dependent budgets were shrinking. The result was the slashing of basic social service spending when local populations were most in need.

That’s bad enough, but the responses of local and international governments, guided by “inaccurate, misleading or partial knowledge”, make a bad situation worse:

While the ‘war on terror’ geopolitical crisis-structure constitutes a conventional ‘security’ response to the militarized symptoms of HSD [Human Systems Destabilization] (comprising the increase in regional Islamist militancy), it is failing to slow or even meaningfully address deeper ESD [Environmental System Disruption] processes that have rendered traditional industrialized state power in these countries increasingly untenable. Instead, the three cases emphasized – Syria, Iraq, and Yemen – illustrate that the regional geopolitical instability induced via HSD has itself hindered efforts to respond to deeper ESD processes, generating instability and stagnation across water, energy and food production industries.” (Failing States, Collapsing Systems, page 59)

This pattern – militarized responses to crises that beget more crises – is not new:

A 2013 RAND Corp analysis examined the frequency of US military interventions from 1940 to 2010 and came to the startling conclusion: not only that the overall frequency of US interventions has increased, but that intervention itself increased the probability of an ensuing cluster of interventions.” (Failing States, Collapsing Systems, page 43)

Ahmed’s discussions of Syria, Iraq, Yemen, Nigeria and Egypt are bolstered by the benefits of hindsight. His examination of Saudi Arabia looks a little way into the future, and what he foresees is sobering.

He discusses studies that show Saudi Arabia’s oil production is likely to peak in as soon as ten years. Yet the date of the peak is only one key factor, because the country’s steadily increasing internal demand for energy means there is steadily less oil left for export.

For Saudi Arabia the economic crunch may be severe and rapid: “with net oil revenues declining to zero – potentially within just 15 years – Saudi Arabia’s capacity to finance continued food imports will be in question.” For a population that relies on subsidized imports for 80% of its food, empty government coffers would mean a life-and-death crisis.

But a Saudi Arabia which uses up all its oil internally would have major implications for other countries as well, in particular China and India.

like India, China faces the problem that as we near 2030, net exports from the Middle East will track toward zero at an accelerating rate. Precisely at the point when India and China’s economic growth is projected to require significantly higher imports of oil from the Middle East, due to their own rising domestic energy consumption requirement, these critical energy sources will become increasingly unavailable on global markets.” (Failing States, Collapsing Systems, page 74)

Petroleum production in Europe has also peaked, while in North America, conventional oil production peaked decades ago, and the recent fossil fuel boomlet has come from expensive, hard-to-extract shale gas, shale oil, and tar sands bitumen. For both Europe and North America, Ahmed forecasts, the time is fast approaching when affordable high-energy fuels are no longer available from Russia or the Middle East. Without successful adaptive responses, the result will be a cascade of collapsing systems:

Well before 2050, this study suggests, systemic state-failure will have given way to the irreversible demise of neoliberal finance capitalism as we know it.” (Failing States, Collapsing Systems, page 88)

Are such outcomes inescapable? By no means, Ahmed says, but adequate adaptive responses to our developing predicaments are unlikely without a recognition that our economies remain inescapably embedded in biophysical processes. Unfortunately, there are powerful forces working to prevent the type of understanding which could guide us to solutions:

vested interests in the global fossil fuel and agribusiness system are actively attempting to control information flows to continue to deny full understanding in order to perpetuate their own power and privilege.” (Failing States, Collapsing Systems, page 92)

In the next installment, Fake News as Official Policy, we’ll look at the deep roots of this misinformation and ask what it will take to stem the tide.

Energy at any cost?

If all else is uncertain, how can growing demand for energy be guaranteed? A review of Vaclav Smil’s Natural Gas.

Near the end of his 2015 book Natural Gas: Fuel for the 21st Century, Vaclav Smil makes two statements which are curious in juxtaposition.

On page 211, he writes:

I will adhere to my steadfast refusal to engage in any long-term forecasting, but I will restate some basic contours of coming development before I review a long array of uncertainties ….”

Link to Vaclav Smil series list.And in the next paragraph:

Given the scale of existing energy demand and the inevitability of its further growth, it is quite impossible that during the twenty-first century, natural gas could come to occupy such a dominant position in the global primary energy supply as wood did in the preindustrial era or as coal did until the middle of the twentieth century.”

If you think that second statement sounds like a long-term forecast, that makes two of us. But apparently to Smil it is not a forecast to say that the growth of energy demand is inevitable, and it’s not a forecast to state with certainty that natural gas cannot become the dominant energy source during the twenty-first century – these are simply “basic contours of coming development.” Let’s investigate.

An oddly indiscriminate name

Natural Gas is a general survey of the sources and uses of what Smil calls the fuel with “an oddly indiscriminate name”. It begins much as it ends: with a strongly-stated forecast (or “basic contour”, if you prefer) about the scale of natural gas and other fossil fuel usage relative to other energy sources.

why dwell on the resources of a fossil fuel and why extol its advantages at a time when renewable fuels and decentralized electricity generation converting solar radiation and wind are poised to take over the global energy supply. That may be a fashionable narrative – but it is wrong, and there will be no rapid takeover by the new renewables. We are a fossil-fueled civilization, and we will continue to be one for decades to come as the pace of grand energy transition to new forms of energy is inherently slow.” – Vaclav Smil, preface to Natural Gas

And in the next paragraph:

Share of new renewables in the global commercial primary energy supply will keep on increasing, but a more consequential energy transition of the coming decades will be from coal and crude oil to natural gas.”

In support of his view that a transition away from fossil fuel reliance will take at least several decades, Smil looks at major energy source transitions over the past two hundred years. These transitions have indeed been multi-decadal or multi-generational processes.

Obvious absence of any acceleration in successive transitions is significant: moving from coal to oil has been no faster than moving from traditional biofuels to coal – and substituting coal and oil by natural gas has been measurably slower than the two preceding shifts.” – Natural Gas, page 154

It would seem obvious that global trade and communications were far less developed 150 years ago, and that would be one major reason why the transition from traditional biofuels to coal proceeded slowly on a global scale. Smil cites another reason why successive transitions have been so slow:

Scale of the requisite transitions is the main reason why natural gas shares of the TPES [Total Primary Energy System] have been slower to rise: replicating a relative rise needs much more energy in a growing system. … going from 5 to 25% of natural gas required nearly eight times more energy than accomplishing the identical coal-to-oil shift.” – Natural Gas, page 155

Today only – you’ll love our low, low prices!

There is another obvious reason why transitions from coal to oil, and from oil to natural gas, could have been expected to move slowly throughout the last 100 years: there have been abundant supplies of easily accessible, and therefore cheap, coal and oil. When a new energy source was brought online, the result was a further increase in total energy consumption, instead of any rapid shift in the relative share of different sources.

The role of price in influencing demand is easy to ignore when the price is low. But that’s not a condition we can count on for the coming decades.

Returning to Smil’s “basic contour” that total energy demand will inevitably rise, that would imply that energy prices will inevitably remain relatively low – because there is effective demand for a product only to the extent that people can afford to buy it.

Remarkably, however, even as he states confidently that demand must grow, Smil notes the major uncertainty about the investment needed simply to maintain existing levels of supply:

if the first decade of the twenty-first century was a trendsetter, then all fossil energy sources will cost substantially more, both to develop new capacities and to maintain production of established projects at least at today’s levels. … The IEA estimates that between 2014 and 2035, the total investment in energy supply will have to reach just over $40 trillion if the world is to meet the expected demand, with some 60% destined to maintain existing output and 40% to supply the rising requirements. The likelihood of meeting this need will be determined by many other interrelated factors.” – Natural Gas, page 212

What is happening here? Both Smil and the IEA are cognizant of the uncertain effects of rising prices on supply, while graphing demand steadily upward as if price has no effect. This is not how economies function in the real world, of course.

Likewise, we cannot assume that because total energy demand kept rising throughout the twentieth century, it must continue to rise through the twenty-first century. On the contrary, if energy supplies are difficult to access and therefore much more costly, then we should also expect demand to grow much more slowly, to stop growing, or to fall.

Falling demand, in turn, would have a major impact on the possibility of a rapid change in the relative share of demand met by different sources. In very simple terms, if we increased total supply of renewable energy rapidly (as we are doing now), but the total energy demand were dropping rapidly, then the relative share of renewables in the energy market could increase even more rapidly.

Smil’s failure to consider such a scenario (indeed, his peremptory dismissal of the possibility of such a scenario) is one of the major weaknesses of his approach. Acceptance of business-as-usual as a reliable baseline may strike some people as conservative. But there is nothing cautious about ignoring one of the fundamental factors of economics, and nothing safe in assuming that the historically rare condition of abundant cheap energy must somehow continue indefinitely.

In closing, just a few words about the implications of Smil’s work as it relates to the threat of climate change. In Natural Gas, he provides much valuable background on the relative amounts of carbon emissions produced by all of our major energy sources. He explains why natural gas is the best of the fossil fuels in terms of energy output relative to carbon emissions (while noting that leaks of natural gas – methane – could in fact outweigh the savings in carbon emissions). He explains that the carbon intensity of our economies has dropped as we have gradually moved from coal to oil to natural gas.

But he also makes it clear that this relative decarbonisation has been far too slow to stave off the threat of climate change.

If he turns out to be right that total energy demand will keep rising, that there will only be a slow transition from other fossil fuels to natural gas, and that the transition away from all fossil fuels will be slower still, then the chances of avoiding catastrophic climate change will be slim indeed.

accounting_for_energy_2For more than three decades, Vaclav Smil has been developing the concepts presented in his 2015 book Power Density: A Key to Understanding Energy Sources and Uses.

The concept is (perhaps deceptively) simple: power density, in Smil’s formulation, is “the quotient of power and land area”. To facilitate comparisons between widely disparate energy technologies, Smil states power density using common units: watts per square meter.

Wonkometer-225Smil makes clear his belief that it’s important that citizens be numerate as well as literate, and Power Density is heavily salted with numbers. But what is being counted?

Perhaps the greatest advantage of power density is its universal applicability: the rate can be used to evaluate and compare all energy fluxes in nature and in any society. – Vaclav Smil, Power Density, pg 21

A major theme in Smil’s writing is that current renewable energy resources and technologies cannot quickly replace the energy systems that fuel industrial society. He presents convincing evidence that for current world energy demand to be supplied by renewable energies alone, the land area of the energy system would need to increase drastically.

Study of Smil’s figures will be time well spent for students of many energy sources. Whether it’s concentrated solar reflectors, cellulosic ethanol, wood-fueled generators, fracked light oil, natural gas or wind farms, Smil takes a careful look at power densities, and then estimates how much land would be taken up if each of these respective energy sources were to supply a significant fraction of current energy demand.

This consideration of land use goes some way to addressing a vacuum in mainstream contemporary economics. In the opening pages of Power Density, Smil notes that economists used to talk about land, labour and capital as three key factors in production, but in the last century, land dropped out of the theory.

The measurement of power per unit of land is one way to account for use of land in an economic system. As we will discuss later, those units of land may prove difficult to adequately quantify. But first we’ll look at another simple but troublesome issue.

Does the clock tick in seconds or in centuries?

It may not be immediately obvious to English majors or philosophers (I plead guilty), but Smil’s statement of power density – watts per square meter – includes a unit of time. That’s because a watt is itself a rate, defined as a joule per second. So power density equals joules per second per square meter.

There’s nothing sacrosanct about the second as the unit of choice. Power densities could also be calculated if power were stated in joules per millisecond or per megasecond, and with only slightly more difficult mathematical gymnastics, per century or per millenium. That is of course stretching a point, but Smil’s discussion of power density would take on a different flavor if we thought in longer time frames.

Consider the example with which Smil opens the book. In the early stages of the industrial age, English iron smelting was accomplished with the heat from charcoal, which in turn was made from coppiced beech and oak trees. As pig iron production grew, large areas of land were required solely for charcoal production. This changed in the blink of an eye, in historical terms, with the development of coal mining and the process of coking, which converted coal to nearly 100% pure carbon with energy equivalent to good charcoal.

As a result, the charcoal from thousands of hectares of hardwood forest could be replaced by coal from a mine site of only a few hectares. Or in Smil’s favored terms,

The overall power density of mid-eighteenth-century English coke production was thus roughly 500 W/m2, approximately 7,000 times higher than the power density of charcoal production. (Power Density, pg 4)

Smil notes rightly that this shift had enormous consequences for the English countryside, English economy and English society. Yet my immediate reaction to this passage was to cry foul – there is a sleight of hand going on.

While the charcoal production figures are based on the amount of wood that a hectare might produce on average each year, in perpetuity, the coal from the mine will dwindle and then run out in a century or two. If we averaged the power densities of the woodlot and mine over several centuries or millennia, the comparison look much different.

And that’s a problem throughout Power Density. Smil often grapples with the best way to average power densities over time, but never establishes a rule that works well for all energy sources.

Generating station near Niagara Falls

The Toronto Power Generating Station was built in 1906, just upstream from Horseshoe Falls in Niagara Falls, Ontario. It was mothballed in 1974. Photographed in February, 2014.

In discussing photovoltaic generation, he notes that solar radiation varies greatly by hour and month. It would make no sense to calculate the power output of a solar panel solely by the results at noon in mid-summer, just as it would make no sense to run the calculation solely at twilight in mid-winter. It is reasonable to average the power density over a whole year’s time, and that’s what Smil does.

When considering the power density of ethanol from sugar cane, it would be crazy to run the calculation based solely on the month of harvest, so again, the figures Smil uses are annual average outputs. Likewise, wood grown for biomass fuel can be harvested approximately every 20 years, so Smil divides the energy output during a harvest year by 20 to arrive at the power density of this energy source.

Using the year as the averaging unit makes obvious sense for many renewable energy sources, but this method breaks down just as obviously when considering non-renewable sources.

How do you calculate the average annual power density for a coal mine which produces high amounts of power for a hundred years or so, and then produces no power for the rest of time? Or the power density of a fracked gas well whose output will continue only a few decades at most?

The obvious rejoinder to this line of questioning is that when the energy output of a coal mine, for example, ceases, the land use also ceases, and at that point the power density of the coal mine is neither high nor low nor zero; it simply cannot be part of a calculation. As we’ll discuss later in this series, however, there are many cases where reclamations are far from certain, and so a “claim” on the land goes on.

Smil is aware of the transitory nature of fossil fuel sources, of course, and he cites helpful and eye-opening figures for the declining power densities of major oil fields, gas fields and coal mines over the past century. Yet in Power Density, most of the figures presented for non-renewable energy facilities apply for that (relatively brief) period when these facilities are in full production, but they are routinely compared with power densities of renewable energy facilities which could continue indefinitely.

So is it really true that power density is a measure “which can be used to evaluate and compare all energy fluxes in nature and in any society”? Only with some critical qualifications.

In summary, we return to Smil’s oft-emphasized theme, that current renewable resource technologies are no match for the energy demands of our present civilization. He argues convincingly that the power density of consumption on a busy expressway will not be matched to the power density of production of ethanol from corn: it would take a ridiculous and unsustainable area of corn fields to fuel all that high-energy transport. Widening the discussion, he establishes no less convincingly, to my mind, that solar power, wind power, and biofuels are not going to fuel our current high-energy way of life.

Yet if we extend our averaging units to just a century or two, we could calculate just as convincingly that the power densities of non-renewable fuel sources will also fail to support our high-energy society. And since we’re already a century into this game, we might be running out of time.
