I’m continuing to read The End of Growth by Richard Heinberg. His book claims that, from his vantage point in 2011, economic growth is no longer possible and that any future growth is a myth propped up by financial trickery. Part of his thesis rests on the idea that economic growth as we know it only came about through continued advancements in hydrocarbon extraction. Oil, coal, and natural gas, these are all commodities of incredibly high energy density but incredibly low transportation costs: burning them is easy and liberates energy. This energy then powers economic growth. He blithely asserts that prior to the discovery and utilization of these hydrocarbons economic growth basically didn’t exist, and when we have used up the last of these hydrocarbons it will cease once again. It’s that first bit I’d like to take issue with today.

Economic growth didn’t start with coal. Mr Heinberg seems to have a very Eurocentric and modern-centric view of history, ascribing 100% of all economic growth to the time after the industrial revolution. It’s true that in millennia past, a nation’s power lay mostly in its raw population total. That’s because 90%+ of all people were usually subsistence farmers, and mobilizing their labor for war or public buildings was how most nations used their power. But growth still occurred before the industrial revolution, and we see evidence of it through history.

For example: technology is growth. If every single year an average person can do more and more using less and less, isn’t that a case of economic growth? Wouldn’t we measure that as an increase in GDP? And technology has been progressing for every millennium of human history, not just the last few centuries. Take Italy in the 16th century and compare it to Roman Latium from the 1st century, a middle class urban Italian could enjoy luxuries the likes of which a senator or emperor could only dream of. Take books for example, in Latium it would have taken a team of scribes several weeks or months to copy by hand all of Julius Caesar’s Bello Gallico, meaning that copies were limited and had to be fiercely protected. Meanwhile an Italian with a printing press could print off a few hundred copies all by himself, selling them and other books out to middle class folk and letting middle class libraries expand to point that people could spend their entire lives just reading (and some folks did just that). In a very real sense we would say that the printing press led to a growth in the Italian economy, because more books could be made with less labor. This freed up labor to do other things, those former scribes could now go on to be writers themselves, or inventors or even go back to the field as farmhands.

If you took the GDP per capita of Roman Latium and compared it to the GDP per capita of 16th Century Florence, you’d find a hell of a lot more stuff being produced per person per year. The printing press and technological innovations like it had allowed the Italian economy to grow in ways that didn’t require extracting more resources out of the ground, and the same holds true in our economy today.

So even if the very last drop of oil or nugget of coal is extracted from our earth, why would we ever believe that growth would stop right there? Oil, coal and gas are just useful stores of energy, there are other ways to store and transport energy that we could use, and further technology that we can develop to grow our economy. A cheap, fast, and accurate 3D printer using solar power and bioplastic would lead to considerable economic growth, and there’s no reason to think its invention would be impossible in a world without oil. So while it may be true that oil is a finite resource, that truth bears no relation to truths about economic growth. Growth has never required oil, even today solar and wind power are becoming greater and greater proportions of our national electric grid, and when we finally transition away from oil growth will not stop, just as the Italians didn’t need oil to start their growth in the 16th century.
