Oil Economics Made Easy

Afterburn Society: Beyond Fossil Fuels

Richard Heinberg (2015)

Film Review

Afterburn Society is about the economics of energy, specifically the energy produced by fossil fuels. The subject of economics is like bad-tasting medicine for a lot of people. However Post Carbon Institute Fellow Richard Heinberg’s jargonless, down-to-earth delivery makes the experience quite painless and even pleasurable.

Heinberg begins by tracing the history of agriculture and manufacturing. Prior to the late 19th century, there were only two sources of energy. People either relied on their own muscle power or they employed traction animals or slaves (ironic, isn’t it, how fossil fuels replaced slavery?).

In contrast, our modern-day food industry relies heavily on fossil fuels to run farm machinery, for plastic packaging (derived from oil), to transport food to market, for nitrogen fertilizer (derived from natural gas) and as a source of herbicides and pesticides (derived from oil).

It takes 350 gallons of oil a year to feed one American and seven Calories* of fossil fuel to produce one calorie of food.

The Law of Diminishing Returns

Heinberg goes on to explain the law of diminishing returns as it pertains to oil production. Over the last eight years investment in oil production has soared, while output per dollar invested has steeply declined. From 1997-2005, oil companies spent $1.5 trillion to produce 86 million barrels of oil a day. Between 2005-2013, they spent $4 trillion to produce 3 million barrels a day.

Industry data reveals conventional oil production peaked in 2005 and has been declining ever since. Most of the new oil production has come from more costly and risky technologies, such as fracking and deep sea oil drilling. The use of these new technologies has increased the cost of oil extraction. This, in turn, has led the price of oil to skyrocket from $27 a barrel in 2000 to $100 a barrel in 2014.

The higher price of oil means a higher return for oil companies. This, in turn, enabled more costly and controversial technologies, such as fracking and deep sea oil drilling have come onboard. They only became economically viable when the price of oil passed $70-80 a barrel.

EROEI

Oil production costs aren’t only increasing in dollar terms, but in terms of the energy required to extract new oil. Heinberg predicts that by mid-century, it will require as much energy to extract a unit of oil and natural gas as that unit will produce when it’s burned. At that point, fossil fuels will cease to be a viable energy source, though they may continue to be useful in producing plastics, synthetic fabrics and other petroleum byproducts.

Overall surplus energy will steeply decline when this happens, as renewable energy technologies have a much lower EROEI (Energy Return on Energy Invested) than fossil fuels. For example, solar energy has an EROEI of 2.5-5 to 1 (2.5-5 units returned for every unit invested), in contrast to oil’s EROEI of 30 to 1. Biofuels, with an EROEI of 1 to 1, are even worse. Their only purpose is to return a profit to government subsidized biofuel merchants like Archer Daniels Midland. They’re useless as an energy source.

The steep decline in surplus energy will translate into major social change, as nearly all of our energy use will be geared towards producing new energy (i.e. food production).

The Recent Drop in Oil Prices

In my view, the only shortcoming in this presentation was Heinberg’s failure to address the steep drop in oil prices that began in June 2014 (from $100 to $48 a barrel, recently leveling off around $60 a barrel). He does discuss it in a December 19, 2014 article The Oil Price Crash of 2014

In brief he attributes the temporary price drop to a decrease in demand (due to deepening recession in China, Japan and Europe), coupled with increasing supply (due to the frantic pace of fracking in the US). Normally when there’s a mismatch in supply and demand, it falls on Saudi Arabia (the world’s top oil exporter) to ramp down production. This time the Saudis have refused to cut back production.

Their motivation is a matter of speculation. According to Heinberg, the most likely reasons are a desire to destroy the US fracking industry (small fracking companies are going bankrupt in droves – they’re up to their eyeballs in debt and fracked oil is only profitable above $70-80 a barrel) – and to punish Russia and Iran (whose economies are totally dependent on oil and gas exports) for meddling in Syria and Iraq.

Did Global Economic Growth End 15 Years Ago?

According to London Broker, Global Economy is Shrinking

The main premise of Life After Growth: How the Global Economy Really Works – and Why 200 Years of Growth are Over  is that global economic growth has ended. Western governments conceal this fact through debt creation, inflation and clever manipulation of statistical economic indicators. According to Tim Morgan, leading analyst at the London financial brokerage Tullett Prebon, economic growth ended in 2000 and the economy has been shrinking ever since.

Morgan attributes the end of global economic growth to the high cost of fossil fuels.* This is because the real economy (which many people confuse with the financial economy) is a direct function of surplus energy. In pre-agricultural times, there was no energy surplus: human beings derived exactly the same amount of energy from their food as they expended acquiring it. With the advent of farming, they managed to produce a small surplus of energy that enabled a small minority to engage in work other than food production.

In the 18th century the invention of the heat engine enabled surplus energy (and the real economy) to grow exponentially over the next 200 years. Now that the cheap fossil fuel has been used up, our energy surplus is declining. This, in turn, is reflected in the gradual shrinkage of the global economy.

Measuring Surplus Energy

Energy surplus is measured as EROEI (Energy Returned Over Energy Invested), the ratio between the energy produced and the energy consumed in the extraction or production process. 1930s oil fields had an EROEI of 100:1. Once the easily accessible oil was used up, the EROEI began to decline. It was 30:1 in 2000 and it declines by about 2% a year. In 2014 it stood at 14:1. Unconventional oil sources have an extremely low EROEI (eg tar sands and fracked shale oil have an EROEI of 3:1).**

Declining EROEI’s are always accompanied by a spike in oil prices. This translates into higher prices for everything, due to the energy required for food production and manufacturing. Owing to higher prices, people consume less and the economy slows.

Globalization Has Been Extremely Damaging

Morgan is highly critical of politicians who fail to distinguish between the real economy of goods and services and the shadow economy of money and finance. He also feels globalization and rampant consumerism have been extremely damaging to the real economy. The mistake western countries made with globalization was reducing their production without reducing consumption. Instead they increased consumption levels by increasing borrowing and debt. Globalization was extremely beneficial for banks, due to the voracious demand for their product (loans). Meanwhile the diversion of large sums from production to the finance sector – aggravated by consumerism and the rise of consumer debt – hastened the decline of the real economy.

This wholesale debt creation and the widening split between the real economy and the financial economy is largely reflected in inflation and the destruction of the value of money. The US dollar lost 87% of its purchasing power between 1962 and 2012, which the government systematically conceals through misreporting of key economic indicators.

All economies function best when the financial economy coincides with the real economy. At present the primary methods of debt destruction are quantitative easing*** and inflation (it’s always easier to repay debts with devalued money). Other methods in the wings are cuts in pensions and Social Security payments and eventually bank failures and government defaults. Morgan feels that resource poor countries like Japan and the UK are at highest risk for default.

How Governments Lie with Statistics

My favorite chapter details the decades of statistical manipulations that have made government indicators of inflation, growth, output, debt and unemployment totally meaningless. John Kennedy was the first to exclude “discouraged” workers (who weren’t actively seeking work) from the unemployment rate. Johnson was the first to conceal the size of the government deficit by including the Social Security surplus in the federal budget. Nixon was the first to exclude energy and food costs (which rise the fastest) from core inflation calculations.

I was most shocked to learn that 16% of GDP consists of “imputations” or dollars that don’t actually exist. The largest single imputation the US government adds is “owner equivalent” rent. This is an amount equivalent to the rent all rent homeowners would have to pay if they didn’t own their own home. In 2011, this added up to $1.2 billion (out of a total GDP of $12.7 trillion).

The second largest imputation involves non-cash benefits employers give their workers (medical insurance, meals, accommodation, etc) and free banking services.

The US Government is Technically Bankrupt

This over-reporting of GDP, combined with under-reporting of inflation, makes it appear that the US economy is growing when it’s not. .

Morgan estimates that as of 2011 true US debt (government, business and personal) was 449% of GDP. Technically this means the US is insolvent as collective liabilities far exceed any realistic prediction of future income.

Politicians Need to Stop Lying

Morgan maintains that industrialized societies urgently need to living with less surplus energy. Rather than continuing to delude themselves (and us), our political leaders must face up to the reality that our claims on future energy surpluses (aka debt) are totally unrealistic.

They need to end globalization and rampant consumerism and enact policies (support for renewable energy, public transport and strong local economies) that will help people adapt to the new economic reality.

*Most analysts predict oil prices will return to $100+ a barrel in June 2015, once the US surplus is used up.
**Some other EROEI’s (for the sake of comparison):
• Coal 8:1
• Solar PVC panels 8:1
• Solar concentrating power: 17:1
• Large hydro generation: 22:1
• Small hydrogenation 32:1
• Landfill/sewage gas cogeneration 40:1
• Onshore wind 20:1
*** Quantitative easing (QE) is an unconventional form of monetary policy where a Central Bank creates new money electronically to buy financial assets, like government bonds. This differs from conventional money creation, in which private banks create money out of thin air as new loans (see An IMF Proposal to Ban Banks from Issuing Money).
