#249: The Surplus Energy Economy, part 4

FRACTURE AND DE-FINANCIALIZATION

Introduction

In this fourth instalment of The Surplus Energy Economy, we turn to perhaps the most complex part of the equation, which is the financial system. The connections between energy and material prosperity, though largely disregarded and dismissed by orthodox economics, are nevertheless comparatively straightforward, at least in principle.

The nearest approach to the straightforward in finance is the concept of money as claim. Once we recognize that money has no intrinsic worth – but commands value only as a ‘claim’ on the output of the material economy – two things become apparent.

The first is that the financial system consists of an aggregate ‘body of claims’ on the material economy of products and services. The second is that the viability and sustainability of the system depends on the extent to which these claims can be honoured ‘for value’ by the real economy. To be a little more specific, the system is viable as long as participants believe that these claims can be honoured.

The situation now is that financial viability depending upon accuracy of proxy has been strained to breaking-point. As we have seen, prior growth in economic prosperity has gone into reverse. At the same time, though, the financial system, as a ‘body of claims’, has carried on expanding, in part because of the fallacious assumption that the material can be driven by the monetary.

As we shall see, there are reasons to suppose that the ‘real’ economy of goods and services is now at least 40% smaller than the ‘financial’ economy of money and credit.

A simple analogy might be useful here. When people arrive at a function, they hand over their hats and coats in return for paper checks, which act as claims. During the function, the managers of the venue print a large number of additional checks. The checks alone will not, of course, keep the attendees warm and dry on their journeys home, for which only physical hats and coats will suffice.

Only at the end of the function does it become apparent that there aren’t enough hats and coats to honour every check. Neither is it clear which checks are or are not valid. The only way to stave off this denouement is to keep the function – or the party – going for as long as possible. 

This is loosely analogous to the current situation, where financial ‘claims’ far exceed the capabilities of the underlying material economy to honour them. Modest disequilibria of this kind can be mediated by inflation which, in our analogy, varies the rate of exchange between checks and coats. But the current extent of disequilibrium could only be mediated by runaway inflation.

Moreover, each person believes that every single check equates to an entitlement to a complete coat or hat. They are not going to be happy when they discover that this is not the case. The term for what ensues is value destruction, which is destined to happen in a way that is likely to be chaotic.

The unfolding squeeze

As well as noting that prior growth in material economic prosperity has gone into reverse, we have also observed that the real costs of energy-intensive necessities are on a strongly rising trajectory.

The resulting process is known here as affordability compression. It has two effects. One of these is a relentless decline in the ability to afford discretionary (non-essential) products and services. The other is that it makes it increasingly difficult for households to ‘keep up the payments’ on everything from secured and unsecured credit to subscriptions and staged-payment purchases.

This process helps us to gauge where the effects of the aforementioned process of ‘value (claims) destruction’ are likeliest to be experienced. As well as undermining sectors which depend on discretionary consumption, affordability compression poses a direct threat to the flows which inform the viability of the financial system. The world is awash with debt and quasi-debt obligations, much of which exist outside the regulated banking system, and some of which cannot even be quantified in their entirety. Many enterprises have been built on a business model which financializes, into capital value, forward income streams whose future reliability has, hitherto, been taken for granted.

Within a material economy, the effects of affordability compression cannot long be ignored. As its reality gains recognition, asset values will fall sharply, albeit more severely in some sectors and asset classes than in others. This process is likely to occur along lines that are already quite predictable. But the real danger lies less in market slumps than in a degradation of the network of inter-connected liabilities that constitute the financial system.

These problems are unlikely to be manageable, meaning that we should anticipate disorderly – and, quite possibly, chaotic – contraction in the financial system. Decision-makers seem to be woefully under-informed about these risks, even though various events, such as the recent LDI problem in the British pensions sector, should have provided clear warning.

For the most part, policy-makers, and perhaps market participants too, continue to believe in an economic orthodoxy which states that the economy can never cease to grow and is not, therefore, subject to material constraints. They also seem to believe, again fallaciously, that the authorities can overcome any and every problem using monetary tools. There is, as yet, little or no appreciation that the banking system cannot lend material resources into existence, and that central bankers cannot conjure low-cost energy out of the ether.

A few simple statistics serve to illustrate this point. Between 2002 and 2021, each dollar of reported growth in GDP was accompanied by $3.10 in incremental debt and an estimated increase of $4.75 in broader obligations. Over that same period, SEEDS calculates that fully 70% of reported “growth” was the cosmetic effect of pouring ever more liquidity into the economy, and counting the transactional use of that money as economic “activity”.

In short, the financial system has parted company with the underlying economy, and the notion that the latter can “grow” sufficiently to re-validate the former belongs in the realm of myth and fable. As will be explained here, we can reasonably conclude that each dollar-equivalent of supposed value in the global financial system is now backed by less than $0.60 in material worth.

Financialization of the economy has been an integral part of the confection created on the basis of absurdly ill-informed expectations for the economic future. Whilst the process of de-globalization is starting to gain some recognition, there is almost no appreciation of the likelihood and consequences of de-financialization.

To explain why these things are happening, we need first to revisit some basics.

Of money and matter

There are, essentially, two ways in which we can seek to understand the working of the economy. One of these is the orthodox approach, which states that the economy can be explained entirely in terms of money. If this were true, it would mean that there need never be any end to economic expansion, because the behaviour of the economy is determined, not by material resources, but by money, a human artefact wholly under our control. This would make feasible the paradox of ‘infinite economic growth on a finite planet’.

The alternative explanation, preferred here, is that the economy is a physical system for the supply of material products and services. Since none of these products and services can be made available without the use of energy, we can conclude that prosperity is a function of the supply, value and cost of energy. Instead of the limitless, immaterial potential of the economy defined as money, the surplus energy approach recognizes the existence of physical constraints to expansion. Though energy is ‘the master resource’, these limits also apply to non-energy resources, and to the finite tolerance of the environment.

Energy-based analysis draws a clear distinction between the material and the financial. The critical concept here is that of ‘two economies’. Effective interpretation of the economy requires an understanding of the difference between a ‘real’ or material economy of products and services and a ‘financial’, representational or proxy economy of money and credit. This conforms to the principle of money as claim, which recognises that “money, having no intrinsic worth, commands value only as a ‘claim’ on the output of the material or ‘real’ economy determined by energy”.

This in turn makes it perfectly possible for us to create ‘excess claims’, meaning a body of monetary claims which exceeds the delivery capability of the underlying economy. That is precisely where we are now. The financial system will be forced to renege on excess claims that the underlying economy cannot honour.

This situation arises from the operation of a fallacious precept, which is that financial expansion can drive growth in the physical economy.

This fallacy can best be explained in terms of what has actually been happening over an extended period. By the 1990s, adverse changes in the energy dynamic had created a phenomenon known as “secular stagnation”, meaning a non-cyclical decrease in economic growth. It was assumed, quite wrongly, that this material deceleration could be overcome using monetary tools.

These efforts began with rapid credit expansion, which led directly to the global financial crisis (GFC) of 2008-09. Thereafter, “credit adventurism” was compounded with “monetary adventurism”, in the form of supposedly “temporary” gimmicks including QE, ZIRP and NIRP.

These initiatives haven’t stemmed the deterioration in material economic expansion, of course, but they have had two extremely negative consequences. First, they have burdened the financial system with vast claims which cannot possibly be honoured in full.

Second, they have abrogated the principles of market capitalism, a system which requires (a) that investors must earn a positive real return on their capital, and (b) that markets should be allowed to price value and risk without undue interference.

It might be thought that repudiation of the principles of market capitalism has a broader significance. In previous generations, the public had a choice between collectivism, on the one hand, and market capitalism, on the other. The public appeal of the collectivist ideal has never recovered from the collapse of the Soviet Union, and capitalism has now been undermined by the abandonment of its central principles. There is no simple answer to the question “what economic system do we have now?”

Be that as it may, our immediate concern, in this instalment of The Surplus Energy Economy, is with the financial situation. The conclusion set out here is that, whilst the material economy might be capable of gradual and managed decline, the financial system cannot escape severe and disorderly contraction.

Questions of equilibrium

The concept of ‘two economies’ sets the context for our interpretation of financial conditions. If the financial system exists as “a body of claims on the material economy”, then its viability depends on the claim-honouring capability of the real economy. Likewise, since prices are financial notations attached to material products and services, then systemic inflation or deflation are functions of changes in the relationship between the material economy and its financial corollary.

The best ‘point of entry’ to this complex situation is the matter of economic equilibrium. Effective functioning of the ‘two economies’ dynamic requires a close relationship between the financial and the material. Put another way, the material economy must be capable of honouring the claims placed upon it by the financial economy.

Small divergences between the two are manageable, and are arbitraged by changes in the level of pricing, because prices are the point of intersection between the material and the monetary. But the emergence of severe disequilibrium means that the financial system has created a large body of claims that cannot be honoured ‘for value’.

Claims that cannot be honoured must, by definition, be repudiated. This can happen in one, or both, of two ways. The first of these is inflationary, whereby a person who is owed $1,000 is repaid in money which has lost a sizeable proportion of its purchasing power or claim value – he or she receives $1,000, but this has the purchasing power of only, say, $500 at the time that the commitment was created. This is known as ‘soft default’. The alternative is ‘hard default’, where the borrower repudiates the obligation on the basis of ‘can’t pay, won’t pay’.

The current situation is illustrated in Fig. 12, in which the ‘financial economy’ is represented by reported GDP, and the ‘real economy’ by prosperity as calculated by the SEEDS economic model. These, to be clear, are measures of flow rather than stock – but the viability of the stock of assets and liabilities depends upon the validity of forward expectations for flow.

As is shown in Fig. 12A, global debt has grown far more rapidly than GDP over an extended period, during which more than $3 of net new debt has been taken on for each $1 of reported “growth”.

As we have seen, much of the supposed “growth” of the past quarter-century has been the cosmetic effect of credit expansion. SEEDS calculates prosperity by (a) stripping out this ‘credit effect’, and (b) deducting trend ECoE – the Energy Cost of Energy – from the resulting underlying or ‘clean’ economic output.

The result, shown in Fig. 12B, is severe disequilibrium between the financial economy (represented by GDP) and the real economy (represented by prosperity). As of the end of 2021, the real economy was 40% smaller than its financial proxy. This gap will continue to widen, unless and until we cease the process of artificially inflating GDP using liability expansion.

Fig. 12

The remaining charts in Fig. 12 calibrate obligation downside by applying this 40% flow indicator to the stock aggregates of debt (Fig. 12C) and broader ‘financial assets’ (Fig. 12D). The latter, as assets of the financial sector, are the liabilities of the government, household and non-financial corporate sectors of the economy. 

The process of equilibrium analysis isn’t designed to anticipate downside in the financial system in any detailed way, and we can deem it probable that the outcome will be worse than this portrayal, not least because of liability inter-connection, and sheer panic. Rather, what is illustrated here is a broad measure of exposure to the destruction or repudiation of commitments. If it transpires that ‘the future isn’t what it used to be’, then expectations, incorporated into values, will be recalibrated accordingly.

As mentioned earlier, if the disequilibrium between ‘claim’ and ‘substance’ was small, it could be reconciled by comparatively modest inflation. But downside of 40% means that, absent hyperinflation, a cascade of hard defaults has become inescapable.

Of pricing and inflation

Before we move on to an assessment of exposure, it’s worth pausing to consider the concept of inflation. A broad definition of inflation is that it measures changes in the general level of prices – but what is meant by ‘price’?

Orthodox economics ascribes pricing to the inter-action of ‘supply and demand’, but both of these are stated entirely financially, meaning that no allowance is made for the material. The role of the material is clearly of huge importance, something which is demonstrated, for example, every time a drought or other untoward event reduces the production of grain. In this situation, the price of grain rises, not because of choices made by suppliers or consumers, but because the material parameters of supply have changed.

From the ‘two economies’ perspective, which does acknowledge the material, a very different definition of price emerges – essentially, prices are the financial notations attached to physical products and services. Two parameters are thus involved in the price equation – one of these is transactional activity, and the other is material availability.

A lack of clarity on the issues of pricing and inflation is implicit in any system of notation which concentrates entirely on the financial, and disregards the material. Thus, the headline definition of inflation as changes in retail or consumer prices disregards changes in asset prices. This has enabled advocates of QE to ignore the “everything bubble” in asset prices and assert that QE ‘isn’t inflationary’.

The reality, of course, is that QE is inflationary, but this inflation occurs at the point at which newly-created money is injected into the system. If, back in 2008-09, QE money had been handed to anglers, the prices of fishing paraphernalia would have soared. In the event, the money wasn’t given to fishermen, but to investors, so it was the prices of assets, rather than of rods, reels and lures, which took off.

By convention, asset price changes are ignored in the computation of inflation. Accordingly, QE could be regarded as non-inflationary so long as its effects were confined to the prices of assets. This changed in 2021, when pandemic responses involved directing QE to households. This, needless to say, resulted in the spread of inflation from assets, where it is disregarded, into consumer products and services, where it makes headlines.

Statisticians do not apply consumer price inflation when calculating ‘real’ economic growth, but use the broad-basis GDP deflator instead. This measure, though, has serious shortcomings of its own. In short, we cannot measure inflation effectively if we confine ourselves to measuring the financial against the financial, whilst disregarding the material.

The SEEDS concept of RRCI – the Realised Rate of Comprehensive Inflation – is designed to overcome these shortcomings, and is compared with the conventional measure of systemic inflation in Fig. 13. As you can see, historic inflation has been understated in relation to the RRCI measure, of which a corollary has been that capital has been priced even more negatively than headline data implies.

Fig. 13

Looking ahead, it seems likely that global systemic inflation will retreat from a 2022 provisional estimate of 9.3%, but is likely to remain between 5% and 6%. This projection suggests that the matrix of factors governing pricing will include (a) continuing rises in the costs of necessities, (b) falls in the prices of discretionaries, (c) asset price corrections, and (d) interest rates that remain negative in relation to RRCI.

How much exposure?

Global financial liabilities need to be understood at several different levels. One of these is conventional debt, and another comprises those broad commitments which are known as ‘financial assets’ but which, as mentioned earlier, are the liabilities of the government, household and PNFC (private non-financial corporate) sectors of the economy. Both debt and broader liabilities can be subdivided into public- and private-sector commitments.

Let’s start putting some numbers on the magnitude of global financial exposure. This is complicated, and Fig. 14 is intended to set out the broad structure of financial liabilities – at constant values – by comparing the end-of-2021 situation with the equivalent position on the eve of the global financial crisis (GFC) in 2007.

Please note that, because international obligations need to be met through market transactions, the data set out in Fig. 14 is stated in dollars converted from other currencies at market rates, rather than on the PPP (purchasing power parity) convention generally preferred in Surplus Energy Economics.

Both charts are calibrated at constant 2021 values, enabling direct comparisons to be made between the scale of liabilities at both dates. The biggest change by far has been the sharp increase in broad financial liabilities, which are estimated to have increased by 90% in real terms between 2007 and 2021, rising from $294tn to $555tn between those years.

With GDP shown for reference, Fig. 14 divides liabilities into government debt, private debt and the aggregate of estimated financial assets. Private debt is further subdivided into sums owed to banks and other lenders.

Fig. 14

Conventional debt data is available from the Bank for International Settlements. BIS data shows that, at the end of 2021, governments owed $84tn (93% of GDP) whilst, within private sector debt totalling $153tn (166% of GDP), $95tn (98% of GDP) was owed to commercial banks.

The real issue, though, isn’t debt, but broader financial exposure. These “financial assets” are reported by the Financial Stability Board.

Financial assets fall into four broad categories. Three of these – central banks, public financial institutions and commercial banks – are self-explanatory, though it’s noteworthy that the total exposure of commercial banks (estimated here at $208tn) far exceeds the conventional debt owed to them by households and PNFCs ($95tn). The fourth is NBFIs, meaning ‘non-bank financial intermediaries’.

We need to be clear that these broad liabilities are very largely unregulated. The FSB is not a regulatory authority, but works to improve transparency and encourage best practice. Individual jurisdictions are under no obligation to supply data to the FSB. As a result, available data is neither complete nor particularly timely, with information relating to the end of 2021 only published on the 22nd December 2022.

In general, commercial banks are regulated where they act as ‘deposit-taking institutions’, meaning that the aim is to protect the public as customers of the banks. This is not the same thing as macro-prudential regulation, whose effectiveness is circumscribed by the exclusion of institutions which do not accept deposits from customers. The effect of tightening regulation on retail banks can be to drive more business towards unregulated players. There is, then, a huge gap in the ability of the authorities to maintain, or even to monitor, macroeconomic stability.

This lack of regulation is particularly important when we look at NBFIs. This sector is commonly referred to as the “shadow banking system”. NBFI exposure is enormous, and can be estimated at about $275tn as of the end of 2021. This exceeds the combined total of global government and private debt ($237tn).

The NBFI sector has various components, which include pension funds, insurance corporations, financial auxiliaries and OFIs (other financial intermediaries). This latter category includes money market funds, hedge funds and REITs.

In an article published in 2021, Ann Pettifor provided a succinct description of the shadow banking system. She traces the rise of the sector to the privatisation of pension funds, which happened in 30 countries between 1981 and 2014, and which, she says, “generated vast cash pools for institutional investors”.

Shadow banking participants “exchange the savings they hold for collateral”, generally in the form of bonds, usually government bonds. Instead of charging interest, they enter into repurchase (repo) agreements whereby the borrower undertakes to buy back the bonds at a higher price.

She points out that securities “are swapped for cash over alarmingly short periods”, and that “operators in the system have the legal right to re-use a security to leverage additional borrowing. This is akin to raising money by re-mortgaging the same property several times over. Like the banks, they are effectively creating money (or shadow money, if you like), but they are doing so without any obligation to comply with the old rules and regulations that commercial banks have to follow”.

Implications

This is a good point at which to pull together some of our observations about the relationship between the economy and the financial system.

First, we have observed how the process of liability expansion has created cosmetic “growth” in GDP, which is mistakenly assumed to be a meaningful measure of economic output. Second, a large proportion of the stock of credit exists outside the envelope of banking regulation and macroprudential oversight. We can note that credit expansion, promoted by keeping the cost of capital at levels below the rate of inflation, has created a hugely over-inflated “everything bubble” in asset prices – and that all bubbles eventually burst. It’s worth remembering that the bursting of a bubble doesn’t, of itself, destroy value – rather, it reveals the value that has been destroyed during the preceding period of malinvestment.

As we have seen, the underlying dynamic of the material economy is imposing affordability compression, which is the combined effect of the erosion of prosperity and rises in the real costs of necessities.

We can trace two logical consequences of affordability compression. One of these is a decline in sectors supplying non-essential products and services to consumers. It’s reasonable inference that, as well as driving down stock prices in discretionary sectors, this will result in business failures and defaults on debt, compounded by the effects of job losses.

The second consequence will be a degradation in the flow of income streams from households to the corporate and financial sectors. This sets the scene for a second set of stock price slumps, bankruptcies, defaults and redundancies.

What these indicators suggest is rapid, largely uncontrolled and disorderly contraction in the financial system, understood as an inter-connected and overlapping network of liabilities. The system holds together only if participants have confidence in the honouring of commitments ‘for value’.

The erosion of this confidence is likely to create a domino effect, which starts at the outer perimeter of unregulated lending and then moves inwards towards the regulated banking sector, with defaults compounded by the undermining of collateral values.

It is likely to be assumed that, as in 2008-09, governments and central banks will be able to intervene to shore up the system, but it is in fact unlikely that this will be possible. Aggregate non-government financial liabilities are nearly twice as large now, in real terms, as they were back in 2007 on the eve of the GFC.

With global GDP (in market-converted dollars) standing at $97tn, it is hard to see how the authorities can bail out any sizeable proportion of an estimated $480tn in non-government liabilities without engaging in the creation of liquidity on a scale that would be certain to trigger runaway inflation. The problem is compounded by the observation that the GDP denominator, at $97tn, is itself a dramatic overstatement of underlying material prosperity, a number which SEEDS puts at only $58tn.

Surplus Energy Economics has never predicted that the economy somehow ‘must’ collapse, noting that the rate of decline in prosperity is comparatively modest, and could be manageable. Recognition of the energy dynamic of prosperity erosion does not compel anyone to join the ranks of the collapse-niks.

But the financial complex, rather than the economy itself, is where real and extreme systemic risk does exist. We might be able, to put it colloquially, to ‘get by with less’, but we cannot ‘meet our commitments with less’. Much of this is a result of ignorance (about the real workings of the economy), intentional denial and limitations in oversight.

With the idea of economic contraction deemed to be (quite literally) unthinkable, it has suited us to assume, quite wrongly, that we can energise the material economy with monetary innovations. As well as failing, this has burdened us with financial commitments that we cannot even fully quantify, let alone honour or manage. An admittedly speculative possibility is that decision-makers might, in desperation, opt for the ‘soft default’ of runaway inflation rather than the ‘hard default’ of reneging on interconnected commitments that cannot be honoured.

As we have seen, the convention of disregarding asset prices within the calibration of inflation has enabled us to operate the system on the basis that ‘QE doesn’t cause inflation’. The situation changed when, during the pandemic crisis, QE was no longer confined to investors, but was extended to consumers as well.

At this point, inflation extended from asset prices to CPI, prompting action – rate rises and QT – from central bankers. The patterns of central bank action are illustrated in Fig. 15, in which policy rates are compared with CPI inflation to calculate illustrative real (ex-inflation) interest rates, and trends in central bank assets are summarised in Fig. 15D. The surge in inflation caused real rates to plunge to extraordinarily negative levels before a combination of rate rises and retreating inflation caused a correction back towards zero.

Thus far, the central banks, led by the Federal Reserve, have shown considerable resolve in their determination to use rate increases, and QT, to tame inflation. It is likely now, though, that CPI and similar calculations of inflation will fall, less because of monetary tightening than in response to economic deterioration.

If, as is to be expected on the basis of energy-based prosperity analysis, this economic deterioration causes asset prices to fall, and drives headline inflation downwards, the ensuing hardship might create calls for monetary easing at an intensity that central bankers may be unable to resist.

Knowing that the excess claims embedded in the financial economy must, by definition, be eliminated in one of only two ways, we cannot rule out a process of inflationary ‘soft default’.

A WORLD LESS PROSPEROUS

Introduction

Now that we have addressed first principles, economic output and the role of energy, we can turn our attention to prosperity. The conclusions set out here are that, whilst aggregate prosperity has gone into decline, the real costs of energy-intensive necessities will continue to increase. This creates leveraged downside in the scope for both capital investment and the affordability of discretionary (non-essential) products and services. The dynamics of prosperity are explored here by reference to the SEEDS economic model.

These conclusions do not, of course, accord with the essentially cornucopian assertions of orthodox economics, but we are in a position to observe that economics and the economy have parted company. It is suggested here that the energy-based interpretation of deteriorating prosperity is consistent with much that we can see around us.

Ultimately, the purpose of economics is – or should be – to identify, explain, calibrate and anticipate the delivery of prosperity. To do this, we need to know what prosperity actually is. Properly considered, prosperity is a material concept, consisting of the products and services that are available to society.

Prosperity isn’t ‘money’ but, rather, the things for which money can be exchanged, which is a significantly different concept. This is why orthodox economics, which concentrates on the financial and pays scant attention to the physical, struggles to interpret the meaning, quantum and processes of prosperity.

By way of analogy, we can usefully equate prosperity with households’ ‘disposable income’, which is what remains after necessary expenses have been deducted from total income. At the macroeconomic level, output is the equivalent of total income, whilst the essential expense of system operation is the Energy Cost of Energy. Therefore, we can define prosperity as output minus ECoE.

In part one of this series, we identified a direct (and remarkably invariable) relationship between underlying or ‘clean’ economic output (C-GDP) and the use of energy. Essentially, economic output rises or falls as the availability of energy increases or decreases, and this connection cannot be circumvented.

In part two, we saw how relentless rises in ECoEs can be expected to continue, whilst increasing supplier costs are likely to combine with decreasing consumer affordability to reduce the quantitative availability of energy. In short, prosperity has started to decline because of rising ECoEs, and this process may be exacerbated by a decreasing supply of primary energy.

The material and the monetary

Though the economy needs to be understood in the material terms of energy, the economic debate is customarily conducted in the language of money. The calculation of prosperity in monetary terms is possible, because we can multiply energy use (calibrated in thermal units) by the relatively invariable unit conversion ratio (stated in money) to measure and project the financial equivalent of material economic output. From this, the deduction of ECoE, as a percentage, identifies prosperity as a financial number.

This calibration of prosperity yields a wealth of useful statistics and benchmarks. We can, for instance, compare the scale of monetary transactions with prosperity to measure the degree of equilibrium (or disequilibrium) in the relationship between the ‘financial’ economy of money and credit and the ‘real’ economy of products, services and energy.

We can likewise use the relationship between the monetary and the material to measure systemic inflation, noting that prices are the financial values attached to physical products and services. These issues will be addressed later in this series.

Now, though, our interest is in the evolution of prosperity and its constituent parts. These are (a) the supply of necessities, (b) capital investment in new and replacement productive capacity, and (c) the scope for discretionary (non-essential) consumption. Critically, whilst aggregate and per capita prosperity are now contracting, the real costs of energy-intensive necessities are rising.

The bottom line is that prosperity excluding essentials – a metric abbreviated in SEEDS terminology as PXE – is in leveraged decline. This means that the affordability both of capital investment and of discretionary consumption is coming under worsening pressure. This process of affordability compression also has implications for the streams of income which flow from households to the corporate and financial sectors.

One conclusion which follows from this is that discretionary consumption will decline. Another, to be examined in the next part of this series, is that the global financial system is in very big trouble.

Past, present and future

From our energy-prosperity perspective, modern economic history fits into a logical framework. The accessing of energy from coal, petroleum and natural gas had a completely transformative effect on the economy. Advances in geographic reach, economies of scale and technology delivered falling ECoEs for most of the period in which energy use was expanding rapidly. Accordingly, for much of the industrial era, surplus – post-ECoE – energy supply increased even more rapidly than the total availability of energy itself.

Latterly, though, the depletion of fossil fuels has started pushing ECoEs back upwards, threatening to bring down the curtain on two centuries of exponential economic expansion powered by oil, gas and coal.

As the fossil fuel dynamic fades out, we can postulate three versions of the economic future. One of these, propounded by conventional economics, says that economic prosperity, being a wholly monetary phenomenon, isn’t subject to material constraints, such as those which apply to energy resources, or the limits of environmental tolerance.

This idea – that innovation in the immaterial field of monetary policy can restore expansion to the delivery of material prosperity – has been tried, and has failed spectacularly, over a quarter of a century of futile financial gimmickry.

Another claim is that technology can provide us with abundant, low-cost energy from renewables. As we saw in part two, this argument isn’t credible, because it overlooks the reality that the potential of technology is bounded by the laws of physics. Renewables cannot replicate the characteristics – including the density, portability and flexibility – of fossil fuels.

This leaves us with the third, least palatable conclusion, which is that prosperity is deteriorating because we have no complete replacement for the fading dynamic of fossil fuels. This downturn in prosperity is by no means a sudden event, but one which can be traced through a long precursor zone of deceleration, stagnation and contraction

Our understanding of prosperity as the post-ECoE value of energy enables us to calculate prosperity at any point in time, and to identify the trends which will determine prosperity in the future. For forward projection, we need to anticipate (a) the amount of energy available to the economy, (b) the financial equivalent of the output provided by this energy, and (c) the proportionate ECoE deduction that differentiates prosperity from output.

Conventional economics cannot calibrate prosperity, because it does not recognize either the energy-output linkage or the ‘first call’ on resources made by ECoE. The best that orthodox economics can do is to count – as GDP – financial transactional activity, a measure which cannot inform us about value created within the economy.

Energy-based modelling, such as the proprietary SEEDS system used here, can calculate prosperity, which can then be used, not just as an analytical and predictive tool, but as a benchmark for referencing numerous other calculations and ratios.

The big picture

Naturally, our first concern here is with the quantum of prosperity itself, stated either as an aggregate or in per capita terms. But we also need to explore a number of other issues which we can access with prosperity itself established.

How, over time, is prosperity allocated between the provision of essentials, the financing of capital investment and the provision of discretionary (non-essential) products and services? Looking ahead to the next instalment of The Surplus Energy Economy, what is the relationship between the ‘real’ economy of prosperity and the ‘financial’ economy of monetary claims on that economy? And what can this relationship between the material and the monetary tell us about inflation?

The outlook for prosperity itself is stark. Until recently, the global economy has carried on expanding, but at a decelerating rate. Now, prior growth in prosperity has gone into reverse. At the same time, the costs of energy-intensive necessities are increasing, not just as absolutes, but as a proportion of available resources. The resulting affordability compression undermines the scope both for discretionary consumption and for capital investment.

As we shall see in part four, there is a severe disequilibrium between the material and the monetary economies, meaning that enormous ‘value destruction’ has become unavoidable. This points towards disorderly degradation within the interconnected liabilities which are the ‘money as claim’ basis of the financial system. 

The basics, at the aggregate level and in per capita terms, are summarised in Fig. 8. Between 2021 and 2040, both energy consumption and underlying output (C-GDP) are projected to decline by -8%. With ECoE likely to rise from 9.4% in 2021 to over 17% by 2040, the fall in aggregate prosperity is leveraged from -8% to -16%. Further (though decelerating) increases in global population numbers indicate that prosperity per capita is likely to be 27% lower in 2040 than it was in 2021.

Fig. 8

It will be obvious that these projections differ starkly from orthodox forecasts, which are rooted in the proposition that financial management can enable economic output to increase in perpetuity, without encountering any material constraints imposed by the finite characteristics of energy, other resources or the environment.

Within our energy-based interpretation we can conclude, not just that output and prosperity have turned downwards, but also that much prior “growth” in reported economic output has been the cosmetic product, not just of disregarding ECoEs, but also of creating transactional activity by the injection of ever-growing quantities of cheap credit and cheaper money into the system.

With these parameters established, our interest now turns to the meaning of prosperity decline. First, though, we need to note that nothing that is happening now has occurred without prior warning.

Indications and warnings

Prior notice of impending economic contraction has taken two forms. One of these is modelled prediction, and the other is the action that has been taken by the authorities.

Where prediction is concerned, pride of place must be given to The Limits to Growth (LtG), published back in 1972. Using the World3 system dynamics model, LtG examined the relationships between critical metrics including population numbers, industrial output, food production, the supply of raw materials and what was then called “pollution”. It concluded that economic growth must come to an end, with indicators pointing towards the early twenty-first century as the period in which this was likely to happen.

The LtG projections have proved remarkably prescient, as has been demonstrated by subsequent re-examinations of the calculations. These warnings were disregarded, not because they were wrong, but because they were inconvenient.

Policy actions and outcomes over the past quarter-century provide equally compelling proof of the gradual onset of economic contraction. We have been applying financial gimmickry in a series of futile efforts to restore economic growth, something which we would not have done had the economy itself been continuing to deliver expansion.

To be clear about this, nobody introduced credit expansion, QE, ZIRP, NIRP or any other expedient for the fun of it, or ‘to see what might happen’. These and other innovations were adopted only because the economy and the financial system were in trouble. Where economic deterioration is concerned, this is ‘the evidence of behaviour’.

In the 1990s, observers identified a phenomenon which they labelled “secular stagnation”, meaning a non-cyclical deterioration in the rate of economic expansion. Because of the convention which insists that all economic issues can be explained in terms of money alone, they did not trace this to its source, which was the relentless rise in trend ECoEs.

Proceeding instead from the mistaken premise that money explains everything in economics, they sought to ‘fix’ this problem with monetary tools. Their solution, amenable to the deregulatory preferences of the day, was to ‘liberalise’ the supply of credit, making debt easier to access than it had ever been before.

This initial policy approach is known here as “credit adventurism”, and there was a period in which it appeared to be working, with global real GDP increasing by 50% between 1997 and 2007. This, though, was accompanied by a 77% real-terms increase in debt, with each $1 of reported “growth” accompanied by $2.40 of net new debt. Stripping out this ‘credit effect’ reveals that, within the total “growth” recorded in this period, more than half (54%) was the purely cosmetic, transactional effect of pouring abundant new credit into the system.

These strains, combined with hazardous lending practices and inadequate regulation, led directly to the global financial crisis (GFC) of 2008-09. Rather than accepting the failure of “credit adventurism”, though, we opted to compound it with “monetary adventurism”. ZIRP, NIRP and QE were used, supposedly on a “temporary” and “emergency” basis, to reduce the cost of capital to negative real levels, where it has remained ever since.

In the process, we abrogated the basic principles of market capitalism, which are that (a) value and risk must be priced by markets free from undue interference, and that (b) investors must earn positive real returns on their capital.

The results of this second-phase gimmickry have been completely predictable although, this time around, the numbers have been even worse. Between 2007 and pre-pandemic 2019, real GDP expanded by 48%, but debt increased by 81%. Each dollar of reported growth now required the creation of more than $3 of net new debt. Fully 64% of all the “growth” recorded between 2007 and 2019 was cosmetic.

The way in which historians of the future are likely to describe this period seems clear – they will recognize that prosperity was trending downwards, and conclude that we were prepared to try anything and everything, however illogical and however dangerous, rather than come to terms with this unpalatable reality. We can best describe the period since the second half of the 1990s as a quarter-century “precursor zone” to the involuntary economic de-growth that has now arrived.

During this long period, economic output and prosperity have followed a process of deceleration, stagnation and contraction. In denying this, and trying to fix a material problem with financial tools, we have created an asset bubble that is destined to burst, and a vast interconnected network of liabilities that cannot possibly be honoured ‘for value’ by a contracting material economy.

Observing prosperity contraction

As we have seen, a deteriorating energy dynamic has put prior growth in economic prosperity into reverse. This process will have to go a great deal further, and continue for a lot longer, before there will be any chance of this reality gaining widespread acceptance. We cannot expect recognition to arrive through persuasion, however logical and evidential such persuasion may be. For those of us who understand the dynamic that has put prior growth in prosperity into reverse, our best recourse is to knowledge, concentrating on the ‘why?’ and ‘what?’ of prosperity contraction.

As we have also seen, the primary factor driving prosperity downwards is the relentless rise in ECoEs. As ECoEs rise, energy availability becomes increasingly problematic, and the post-cost value of remaining energy supply decreases.

The way in which this works shows stark regional differences, and these are illustrated in Fig. 9, where trends in real prosperity per capita are compared with ECoEs.

In the United States, prosperity per person turned down after 2000, with the same thing happening in Britain in 2004. But Chinese prosperity per capita has carried on improving, and is only now drawing close to its point of reversal.

These inflexion-points have occurred at very different levels of ECoE. When prosperity turned down in America in 2000, national trend ECoE was 5.1%, and the British equivalent in 2004 was 4.7%. Almost all Western economies experienced prosperity reversal in the years before 2008, when global ECoEs were still below 6%. Yet if, as is now projected by SEEDS, prosperity per person in China turns down in 2023, it is likely to have happened at an ECoE above 11%.

The cause of these differences can be traced to comparative complexity. The high levels of complexity in the Advanced Economies result in upkeep expenses which increase these economies’ sensitivities to rising ECoEs. In almost all Western countries, prosperity per capita had turned down even before the 2008-09 GFC.

Less complex EM (emerging market) economies, which have lower systemic maintenance costs, are better equipped to cope with rising ECoEs. Only in recent years, at higher levels of ECoE, have EM countries started to encounter the process of prosperity reversal long ago experienced in the West. Whilst Mexican prosperity per capita inflected in 2007, and the same thing happened in South Africa in 2008, prosperity did not turn down in Brazil until 2013, followed by India and Indonesia in 2019, Turkey in 2021 and South Korea in 2022. One of the last countries to encounter this turning-point might be Russia where, all other things being equal, prosperity per person could carry on increasing until 2025.

The global result has been a long plateau in prosperity per capita, as shown in Fig. 9D. This plateau has been caused by continuing progress in EM countries offsetting deterioration in the West.

We do not need to conclude, as many have, that some form of greater national ‘vibrancy’ explains the superior economic performance of countries such as China, India, Russia and Brazil in comparison with supposedly ‘staid’ Western economies. Rather, the explanation lies in the varying impact of rising ECoEs in countries with differing levels of complexity.

As a rule-of-thumb, we can state that Advanced Economies need ECoEs of less than 5% if they are to grow their prosperity, whereas EM countries can carry on doing so until ECoEs are between about 8% and 10%.

Fig. 9

Essentials – the leveraged equation

Based on SEEDS analysis, aggregate global prosperity is likely to have peaked last year, at $88tn and will, by 2030, have fallen by a seemingly-modest 3%, though even this will equate to a 10% decrease in per capita terms. By 2040, aggregate prosperity is expected to have fallen by 16%, and its per capita equivalent by 27%, from their 2022 levels.

These references, though, are to top-line prosperity, whether expressed per capita or in aggregate. Our need now is to calculate what deteriorating prosperity is likely to mean in terms both of economic activities and of lived experience.

What we are watching is a two-stage process in which, just as top-line prosperity is falling, the real costs of energy-intensive necessities are rising. This creates a process of affordability compression which has far-reaching implications.

Conventional economic presentation divides the economy into sectors, which are households, government and business, with the latter sometimes further subdivided into financials (such as banks and insurers) and private non-financial corporations (PNFCs).

The SEEDS preference, on the other hand, is for functional segments, which are the supply of essentials, capital investment in new and replacement productive capacity, and discretionary (non-essential) consumption.

There is no hard-and-fast definition of ‘essential’ which, in any case, varies between countries and over time. Many products and services now deemed essential were regarded as ‘luxuries’ (discretionaries) in earlier times. This process of definitional change can be expected to continue, though this time in the opposite direction, with some things now seen as essential once again becoming discretionaries as prosperity contracts.

SEEDS analysis of ‘essentials’ fall into two categories. The first of these is public services provided by the state. This is not to assert that every service made available by government is indispensable, but these services rank as ‘essential’ because the individual has no discretion – choice – about paying for them. This definition does not embrace all public spending, because it excludes those transfers (such as pensions and welfare benefits) made between groups. The other category of essentials is household necessities.

It will be apparent that, in definitional as well as quantitative terms, the ‘essentials’ numbers used by SEEDS are estimates. The composition of ‘essentials’ varies between countries, not least because services provided by the government in some states are paid for privately in others.

Going forward, the general picture seems to be that public service costs are growing by about 1.5% annually on a per capita basis, with the costs of household necessities increasing by about 2.0%. Both are ‘real’ measurements, meaning that they are increases in excess of broad inflation. Rises in the real costs of necessities clearly over-shot this trend in 2022, because of sharp increases in the costs of energy and food. Inflation itself is an issue that will be examined later in this project.  

Harmonised analysis

As we have seen, reported GDP is a misleading metric, capable of being inflated artificially by precisely the kind of credit expansion that we have been experiencing over a very long period. Even so, latest-year GDP is a number in common use, and it’s helpful, for purposes of comparison, to base some SEEDS projections on this number. In SEEDS terminology, this is known as harmonised analysis.

This process is illustrated in Fig. 10, which presents global GDP on three different formats. The first of these is nominal, otherwise called ‘current money’, in which GDP is shown without adjustment for inflation. On this basis, global GDP rose from $53tn in 2001 to $147tn in 2021, an increase of 177% (see Fig. 10A).

It is essential, of course, that adjustment is applied for changes in the general level of prices. In conventional economics, this is undertaken by applying the broad-basis GDP deflator to convert historic numbers into their current-value equivalents. With 2021 set as 100, the global GDP deflator for 2001 is 72.6 and, on this basis, GDP for that year is revised upwards, by 100/72.6, from $53tn at current prices to $73tn at 2021 values. On this basis, ‘real’ growth in GDP was 101% between these years (Fig. 10B).

As we have seen, though, this trend in recorded real GDP does not reflect the progression of prosperity over time – GDP has been inflated artificially through credit expansion, and no allowance has been made for ECoE.

Using 2021 GDP as a basis for comparative forecasting does not remotely mean that we should accept the misleading past trends presented by conventional data. SEEDS analysis informs us that prosperity increased by only 32%, rather than the reported 101%, between 2001 and 2021. The application of this pattern to prior years gives us a ‘harmonised’ trajectory, whereby 2021-equivalent output in 2001 wasn’t $73tn, but $111tn. This is shown in Fig. 10C.

As Fig. 10D illustrates, underlying growth (shown in red) has been far lower than the reported equivalent over an extended period, and has now turned negative.

Fig. 10

Segmental interpretation

Restating past trends in economic prosperity has two purposes, both of which are extremely important. First, it provides a historical context for forward projections. Second, it gives us an ability to interpret segmental trends as they affect essentials, capital investment and discretionary consumption. This is illustrated in Fig. 11, where the first three charts correspond to their ‘nominal’, ‘real’ and ‘harmonised’ equivalents in Fig. 10.

Nominal progressions (Fig. 11A) are of no great significance, as it’s generally recognised that allowance has to be made for inflation. But the inadequacy of past restatement on the basis of ‘real’ GDP is of huge importance. Seen in this conventional way, the rate of increase in the real costs of essentials has been more than matched by growth in top-line output, enabling both capital investment and the affordability of discretionaries to expand. Continuation of these positive trends – particularly in discretionary sectors – is the default assumption for anyone, in business or government, who makes plans on the basis of economic orthodoxy.

Quite how mistaken such assumptions are is apparent in Fig. 11C, which sets out segmental progressions and projections on the basis of output harmonised to trends in prosperity. As prosperity deteriorates in a way that orthodox interpretation cannot project – and as the real costs of essentials continue to rise – the affordability both of capital investment and of discretionary consumption are set to decline markedly.

It’s worthwhile pausing to contemplate what this means. Anyone involved in capital investment, or in the supply of discretionary products and services to consumers, is likely to be planning in the mistaken belief that these activities can be relied upon to expand. He or she is being misled by fallacious interpretations of the past into unrealistic expectations for the future.

This issue of mistaken expectation is captured in the metric PXE. Meaning prosperity excluding essentials, PXE is a measure of the past and projected combined affordability of capital investment and non-essential consumption.

In Fig. 11D, PXE is shown in two formats. The harmonised, SEEDS-interpreted history and outlook for PXE is shown in blue, and the equivalent based on orthodox economics is shown in black.

Anyone planning on the conventional basis is using past growth (most of which didn’t actually happen) to project forward expansion (which is an unrealistic expectation). By comparing these lines, we can see the extent of mistaken expectation informing decisions in capital investment and in discretionary sectors.

We don’t, in fact, need to rely on projection, in that ‘affordability compression’ has already become a reality. But the fundamental significance of this process lies in its implications for the financial system, something which will be examined in the next part of this series.

In essence, affordability compression doesn’t only mean that consumers are going to have to adjust to a decreasing ability to make non-essential purchases. It also means that households will find it an ever-greater struggle to ‘keep up the payments’ on everything from secured and unsecured credit to staged-payment purchases and subscriptions.

Readers can reach their own conclusions on what this means for individual sectors and for the broad shape of the economy. Our interest turns next to what declining prosperity and worsening affordability compression are likely to mean for the financial system.

#247: The Surplus Energy Economy, part 2

THE ENERGY DYNAMIC

Introduction

As we have seen in part one of this series, underlying or ‘clean’ economic output, known here as C-GDP, has correlated remarkably closely with primary energy consumption over a period of more than forty years. This means that we cannot “de-couple” the economy from energy use. This conclusion is wholly logical, given that nothing which has any economic value whatsoever can be supplied without the use of energy.

In part two, our aim is to assess the outlook for the supply and cost of energy, because this will determine the prospects for economic output and prosperity. We conclude that, despite their unquestionable importance, alternative energy sources cannot provide a complete or like-for-like replacement for the energy value hitherto sourced from oil, natural gas and coal.

As is apparent in Fig. 4 – charts in this series are being numbered consecutively – there has been a direct correlation between the exponential increases in, on the one hand, the use of energy and, on the other, population numbers and the economic means of their support. The exponential trends in both series started in the late eighteenth century, which was when the Industrial Revolution began, its symbolic commencement being James Watt’s landmark completion of the first truly efficient heat-engine in 1776.

In short, Fig. 4A provides the clearest possible demonstration of the fact that the economy is an energy system, and that exponential expansion in population numbers and economic output was the direct result of discovering how to harness fossil fuel energy.

A second turning-point can be seen in the years after the Second World War. For much of the period since then, energy use (measured in billions of tonnes of oil-equivalent) has expanded even more rapidly than the population has increased.

This has meant that consumption of energy per capita has risen markedly, as shown in Fig. 4C. But the likelihood now is that the availability of energy will decline, both in aggregate (Fig. 4D) and in per capita terms. If this is what is happening, it means that both economic output and material prosperity have started to contract.

Fig. 4

Cost – the critical role of ECoE

The second of the three ‘first principles’ set out in part one is that energy is never ‘free’. Whenever energy is accessed for our use, some of that energy is always consumed in the access process. This ‘consumed in access’ component is known here as the Energy Cost of Energy, or ECoE.

Trend ECoEs are on a relentlessly rising trajectory, and this is the primary cause of a process of deterioration which has seen growth in economic prosperity decline, stagnate and – now – go into reverse. Overall ECoEs (from all sources of energy) have risen from 2% in 1980 to 4% in 2000, and 10% now. The high-maintenance industrial economy cannot cope with double-digit ECoEs – and there’s worse to come.

If ECoEs had stayed at 2%, the economy would still be growing robustly on the basis of abundant low-cost energy, and we wouldn’t have stretched the financial system to breaking-point by piling on vast quantities of debt and other liabilities in pursuit of the chimera of credit-fuelled “growth”.

If they had stuck at, say, 5%, growth would have been over in the West, but would be continuing in less complex EM (emerging market) countries. As it is, ECoEs have reached levels at which global economic contraction has become inescapable.

It’s vital, then, that we understand ECoE, the factor which, whilst it is ignored by orthodox economics, goes further than any other to explain why prior economic growth has gone into reverse. How do ECoEs evolve, and what effects do they have?

Coal, oil and natural gas are the sources of energy on which the modern economy has been constructed, and they continue to account for more than four-fifths of primary energy supply. This is where our consideration of ECoE needs to start.

Although data for earlier periods is not available, it’s clear that the ECoEs of fossil fuels declined during most of the industrial era, probably reaching their nadir in the quarter-century after 1945.

Our use of fossil fuels began with small deposits, largely discovered on a happenstance basis, which were extracted, processed and delivered using rudimentary technologies.

Three processes contributed to a subsequent long decline in ECoEs.

First, as the energy industries expanded, they reaped continuing economies of scale. The relationship between fixed and variable costs dictates that a large oil, gas or coal field is less expensive to develop and operate in unit terms than a smaller one, and this applies to processing and distribution systems as well.

At the same time, the global search for lowest-cost energy supplies reduced ECoEs through the process of geographic reach. A notable milestone in this progression was the discovery and development of the vast petroleum resources of the Middle East. Despite the hopes that have been vested in various basins in more recent times, the industry has never found anything on a scale which compares with the enormous oil wealth of the Middle East. Whilst we cannot rule out the possibility that reserves of comparable size might yet be found elsewhere, we do know that any such discoveries would be remote, and technically challenging, meaning costly to access.

The third factor which has driven fossil fuel ECoEs downwards over time has been technical progress, at every stage of the chain from extraction to processing and distribution. This process has been gradual and, in an era in which excessive faith is often vested in technology, we need to remind ourselves that the capabilities of technology are limited by the laws of physics.

The ‘shale revolution’ is a case in point. The technological advances in fracturing made the extraction of shale energy more cost-effective than the extraction of those same resources would have been at an earlier time. But it did not – and could not – turn American oil and gas resources into the equivalent of Saudi Arabia, an outcome precluded by the differing characteristics of the resources in question. This is why shale has not been hugely profitable, despite many expectations to the contrary.

Technology accelerated the downwards trend in ECoEs, and can mitigate the upwards trajectory driven by depletion, but is limited by the physical characteristics of resources.

Once the benefits of scale and reach had been exhausted, a new factor became the driver of ECoEs. This factor is depletion, a term which describes the natural process whereby lowest-cost resources are used first, leaving costlier alternatives for later. Unlike reach and scale, depletion pushes trend ECoEs upwards rather than downwards.

We need to be clear that we are not going to ‘run out of’ oil, or, for that matter, gas or coal. Rather, what we are experiencing is a relentless increase in costs, as older (and generally larger and simpler) deposits are exhausted, and are replaced by resources which are higher-cost, and are often smaller, more remote and more technically challenging than previous sources.

The broad ECoE situation is illustrated in Fig. 5. It must be emphasised that the left-hand diagram (Fig.  5A) is a stylized, explanatory representation of the “ECoE parabola”, illustrating how ECoEs, initially driven downwards by scale and reach, then turn upwards as a result of depletion, with technology moving from an accelerating to a mitigating role.

Fig. 5

The central chart (Fig. 5B) shows the projection that, with the ECoEs of fossil fuels on a sharply rising trajectory, neither renewables, nor increased contributions from nuclear and hydroelectric power, are likely to do more than moderate the rising trend in overall ECoEs.

In SEEDS analysis, ECoE defines the difference between economic output and material prosperity. As energy supply becomes more challenging, whilst ECoEs continue to increase, prosperity is in the process of declining more rapidly than output measured as C-GDP (Fig. 5C). These are issues to which we shall return.

Matters at issue

At a later stage in this series, we’ll look at the evolution of prosperity in detail, but it’s helpful at this point to remind ourselves of what is at stake. The charts in Fig. 6 are designed to put this into context. For comparison, each is indexed, with 2021 set at 100.

Conventional data informs us that GDP, generally – though mistakenly – assumed to measure economic output and prosperity, was 101% higher in real terms in 2021 than it had been back in 2001 (Fig. 6A). Population numbers increased over that period but, nevertheless, GDP per capita rose by 62% between those years (Fig. 6B). Both of these positive trends are, we are told, capable of continuing indefinitely.

Energy-based interpretation, conducted using the SEEDS economic model, presents a completely different picture. Growth in aggregate prosperity did occur between 2001 and 2021, but SEEDS puts this at only 32% (Fig. 6C), meaning that the world’s average person was only 6%, rather than 62%, more prosperous in 2021 than he or she had been back in 2001 (Fig. 6D).

Fig. 6

Needless to say, this average person’s share of the world’s aggregate debts has increased dramatically, real debt per capita having expanded by 125% between those years – and even this doesn’t cover the broader liabilities embodied in the financial system.

More important still, SEEDS projects that aggregate prosperity is close to its point of inflexion, whilst prosperity per person has already turned down.

Here, then, is the point of contention. In stark contrast to the perpetual growth promised by orthodox economics, energy-based analysis informs us that prosperity can only expand, or even be maintained at current levels, if two conditions can be satisfied.

If aggregate prosperity is to be maintained, aggregate energy supply must not decrease, and we must find a way to stop further increases in trend ECoEs. Unless both conditions can be met, the economy gets smaller, with consequences that will be examined later in this series.

The outlook for supply

The ECoEs of fossil fuels are rising relentlessly, and will continue to do so. This means that volumetric supply of fossil energy is destined to contract.

This can be explained in terms of pricing which, for any energy source, has to meet two tests. First, it must cover suppliers’ costs. Second, it must be affordable for the consumer.

This can be said of any product or service, but the difference with energy is that the affordability of the consumer is determined by the energy to which he or she has access. This isn’t, then, the same kind of supply and demand equation that we might apply to non-energy products and services.

A person might or might not buy a cup of coffee or a refrigerator at its current price, but being unable or unwilling to make these purchases doesn’t reduce his or her income. This is where energy is profoundly different – a reduction in the supply of energy makes the economy poorer.

When ECoEs rise, not only do suppliers’ costs increase, but there is a simultaneous decrease in the prosperity (and hence in the affordability) of the consumer.

When costs are low, price-arbitraging the needs of producers and consumers is straightforward, because the available value margin is wide enough to satisfy both.

As costs rise, though, a point is reached at which volumes contract, because the costs of producers rise at the same time as the affordability of consumers declines. Far from being driven upwards by scarcity, fossil fuel prices might well decline in accordance with the decreasing prosperity (and hence affordability) of the user. This means that energy markets cannot be relied upon to give us advance warning about economic deterioration.

The SEEDS model uses a set of projections which sees the aggregate of fossil fuel supply falling by 18% between 2021 and 2040. Unless offset by increases from non-fossil sources, this would reduce total primary energy supply by 15% over that period.

It’s certainly possible that the supply of nuclear power will increase, but this is expensive, and would require a major resource investment commitment from an economy which, from now on, isn’t growing. The big problem here is scaling. As of 2021, the nuclear sector supplied only 4.5% of the world’s primary energy and, taking not just resource needs but construction times as well into account, it’s extremely unlikely that we can double, treble or quadruple nuclear generation in a comparatively short period of time. Nuclear fusion is plausible in theory, but has remained twenty-five years in the future throughout the lifetime of anyone reading this article.

Scenario assessment

What this means is that practical hopes for replacing dwindling fossil fuel energy are vested in renewables, with wind and solar power the renewable energy (RE) categories deemed to be capable of rapid expansion. In Fig. 7, we look at the demands that REs will be required to meet under four different scenarios.

In each instance, the focus is on the combined supply of energy from wind and solar power, which is shown in orange. For simplicity, it is assumed in all scenarios that fossil fuel supply declines by 18% between 2021 and 2040, and that there are modest increases in the availability of energy from nuclear and hydroelectric power.

In the first scenario (Fig. 7A), there is no increase in wind and solar from the 675 mm toe (tonnes of oil-equivalent) supplied in 2021. On this basis, and despite incremental contributions from nuclear and hydro, total primary energy availability is 12% lower in 2040 than it was in 2021.

In the second scenario, the aim is to see what needs to happen to keep the total supply of energy unchanged throughout the forecast period (Fig. 7B). For this to happen, and with all other parameters unchanged, supply from wind and solar has to be 250% higher in 2040 than it was in 2021. This might be feasible – we’ll look at the challenges shortly – but energy supply per capita would fall markedly, and the economic situation would be worsened by continuing increases in overall ECoEs.

If prosperity is to stand any chance of being maintained at current levels – taking into account rising ECoEs – aggregate energy supply needs to grow by at least 1.5% annually (Fig. 7C). For this to happen, we would need a 900% increase in the supply of energy from wind and solar power. This is roughly the set of projections which corresponds to the lower end of consensus expectations, and we’re not jumping too far ahead if we state here and now that this is extremely improbable.

The final scenario (Fig. 7D) is the one actually used in SEEDS analysis. By 2040, fossil fuel supplies are 18% lower than they were in 2021. Wind and solar power, taken together, have increased by 90%. There has been a 21% rise in the combined contribution of nuclear and hydroelectricity, and a modest increase from renewable sources other than wind and solar.

In this scenario, the aggregate supply of primary energy falls by 8%, and energy availability per capita is 20% lower in 2040 than it was in 2021.

Fig. 7

The limits to transition

Simply stated, the consensus view is that the supply of energy from wind and solar power will increase so dramatically in the coming decades that we can reduce or even eliminate the use of climate-damaging fossil fuels without experiencing any contraction in the economy. There can be no question about the importance of the environmental imperative contained in this view.

But the orthodox line doesn’t just postulate the attainment of environmental sustainability through like-for-like transition to renewables, let alone suggest that we can attain sustainability by making some economic sacrifices, which might be a reasonable point of view.

Rather, it holds out the bold promise of “sustainable growth”.

We’re told, for instance, that most of the world’s vehicles – totalling close to 2 billion, and including 1.1 billion cars – can be replaced with electric vehicles (EVs). The aggregate of global prosperity will carry on growing indefinitely, perhaps by between 3% and 3.5% annually, meaning that the economy will be somewhere between 75% and 90% bigger, in real terms, in 2040 than it was in 2021. Needless to say, there won’t have to be significant sacrifices made by the public, who will carry on driving, flying and consuming at ever-increasing rates.

All of this depends absolutely on dramatic expansion in the energy supplied by renewables, which really means by wind and solar power, as these are the two categories which are capable, at least according to the orthodox narrative, of major increases in scale. The ability of these sources of supply to increase is not a matter of dispute. The question is whether they expand by enough to take over from fossil fuels.

It has to be said that the consensus scenario of seamless transition owes almost everything to assumption, and virtually nothing to a realistic appraisal of what is achievable within available resources and the parameters set by the laws of physics. The latter is a good place to start an investigation of what might be possible for energy transition.

There are, broadly speaking, two ways in which the supply of any material product can be increased. One of these is to increase the technical efficiency of the supply process, and the other is to expand production capacity. If a manufacturer wants to double his output of widgets, he can either find machinery which is twice as efficient as what he is using now, or double the size of his factory.

Where efficiency is concerned, the harnessing of energy is subject to the laws of physics, which set limits to what is possible. This is certainly true of renewables. The potential efficiency of wind power is determined by Betz’ Law, which states that a maximum of 60% of the kinetic energy of wind can be captured by a turbine. The equivalent for solar is the Shockley-Queisser Limit, which is 34%.

For practical purposes, two observations need to be made here. First, we cannot expect to lift conversion efficiency all the way to the Betz and Shockley-Queisser maxima, because no technology can attain perfect theoretical efficiency.

Second, and more importantly, current best practice is already close to theoretical maxima. The conversion ratios of solar panels (where the limit is 34%) already exceeds 26%. The efficiency of wind energy conversion, where the maximum is 60%, is already above 40%.

In short, and whilst technical progress is likely to continue, there can be no quantum leap in conversion efficiencies, a conclusion well stated here.

If we are to attain very large increases in the supply of wind and solar power, the heavy lifting will have to be done by capacity expansion.

The cost of transition to renewables has been calculated, and is known to be enormous, well in excess of USD 100 trillion. What matters, though, isn’t the financial cost, but what that cost means in terms of the material inputs to be purchased with it.

Rapid expansion (and maintenance) of wind and solar generating capacity and distribution will require vast amounts of concrete, steel, copper, plastics, lithium, cobalt, nickel, graphite, rare earths and numerous other raw materials. It is by no means clear that these materials even exist in the requisite quantities – and the environmental and ecological effects of accessing them are likely to be severely adverse.

On one point there is no scope for dispute – making these raw materials available on a huge scale will require the use of correspondingly vast amounts of energy.

Two further considerations exacerbate the input problem. The first is the intermittency of wind and solar power, and the second is the intrinsic difficulty of storing electricity when compared with the storage of fossil fuels. In the absence of fossil fuel back-up, intermittency requires both surplus capacity (for use when the sun is shining and the wind is blowing) and large and efficient methods of storage.

Both of these considerations leverage the necessary quantities of material inputs. Battery weight is about 60X higher than the weight required for the storage of an energy-equivalent quantity of fossil fuels, and between 50 and 100 tonnes of raw materials are needed for each tonne of batteries produced. In some applications, hydrogen might be a viable alternative storage technology, but hydrogen does not exist in its natural state, and its manufacture is energy-intensive.

This is why systemic capacity for the storage of electricity remains very small indeed. Inventories of petroleum are customarily recorded in days, weeks or months, but electricity reserves are calculated in minutes. In the report cited above, it was stated that “[t]he annual output of Tesla’s Gigafactory, the world’s largest battery factory, could store three minutes’ worth of annual U.S. electricity demand. It would require 1,000 years of production to make enough batteries for two days’ worth of U.S. electricity demand”.

It needs to be noted, too, that capacity expansion targets need to take account of the ageing and replacement, not just of batteries, but of wind turbines and solar panels as well.

The second compounding factor is the shape of planned application. It is, for example, one thing to use renewable electricity to power trams or electric railways, but quite another to supply huge numbers of EVs.

What we are trying to do is to transition vehicles – and numerous other systems created on the basis of fossil fuels – to a completely different source of energy. This isn’t how energy-using technologies develop. The Wright Brothers didn’t invent the aeroplane and then sit around waiting for someone to discover petroleum.

Rather, technologies need to be developed in accordance with the energy available. But there is no preparedness to accept that trains and trams might make more sense than cars in a transport system powered by electricity rather than by petroleum. Even the humble bitumen used in road surfaces is sourced from oil.

Serious though these problems are, we have yet to come to the clincher on seamless transition. Even if we assume that all necessary materials for renewable transition exist in the required quantities, they still need to be extracted, processed, manufactured and delivered, and this requires massive quantities of energy that can only come from the legacy energy of fossil fuels. This, in turn, ties the ECoEs of renewables to those of oil, gas and coal.

Even if supplies of fossil fuel energy could be relied upon to continue at current levels, nobody has yet postulated the current uses of this energy that will be relinquished to free up energy for the purposes of transition. Are we prepared to drive less, fly less or consume less, in order to make energy available for the extraction and processing of steel, copper, lithium and cobalt?

A rocky road ahead

The situation, in summary, is that (a) fossil fuel supplies can be expected to decrease more rapidly than alternatives can be expanded, and (b) that the material connection between renewables and fossil fuels makes it implausible that the relentless rise in ECoEs can be stemmed, still less reversed, by renewables expansion. As we have seen, decreasing energy availability reduces economic output, whilst rising ECoEs leverage the adverse consequences for prosperity.

The Surplus Energy Economics project concentrates on the analytical rather than the prescriptive, and the foregoing should not be taken as disputing the imperative of transition to renewables.

On the contrary, renewables offer our best chance of mitigating economic decline. If we decided to stick with fossil fuel energy and back-pedal on renewables, the economy would contract under the combined pressures of decreasing energy supply and relentlessly rising ECoEs.

There is not, as is so often assumed, any necessary contradiction between our economic and our environmental best interests, which means that transition is imperative for economic as well as environmental reasons. If we tried to carry on with reliance on fossil fuels, we might wreck the environment but would definitely wreck the economy, as supplies of fossil energy decline, and their ECoEs soar.

But there really is no justification for techno-optimism around transition, and claims that “sustainable growth” is assured are starkly at odds with reality. The fact of the matter is that fossil fuels offer energy density, flexibility and portability that no other source of primary energy can match.

We cannot circumvent the laws of physics, nor sever the necessary connection between energy use and economic output. Neither can we reverse the rise in ECoEs by switching to lower-density sources of energy supply.

With this understood, we can move on to assess the outlook, first for economic prosperity, and then for the financial system.
