And why the struggle for a new economic paradigm is about to get real

A groundbreaking study in Elsevier’s Ecological Economics journal by two French economists, for the first time proves the world has passed a point-of-no-return in its capacity to extract fossil fuel energy: with massive implications for the long-term future of global economic growth.
The study, ‘Long-Term Estimates of the Energy-Return-on-Investment (EROI) of Coal, Oil, and Gas Global Productions’, homes in on the concept of EROI, which measures the amount of energy supplied by an energy resource, compared to the quantity of energy consumed to gather that resource. In simple terms, if a single barrel of oil is used up to extract energy equivalent to 50 barrels of oil, that’s pretty good. But the less energy we’re able to extract using that single barrel, then the less efficient, and more expensive (in terms of energy and money), the whole process.
Recent studies suggest that the EROI of fossil fuels has steadily declined since the early 20th century, meaning that as we’re depleting our higher quality resources, we’re using more and more energy just to get new energy out. This means that the costs of energy production are increasing while the quality of the energy we’re producing is declining.
But unlike previous studies, the authors of the new paper — Victor Court, a macroeconomist at Paris Nanterre University, and Florian Fizaine of the University of Burgundy’s Dijon Laboratory of Economics (LEDi)—have removed any uncertainty that might have remained about the matter.
Point of no return
Court and Fizaine find that the EROI values of global oil and gas production reached their maximum peaks in the 1930s and 40s. Global oil production hit peak EROI at 50:1; while global gas production hit peak EROI at 150:1. Since then, the EROI values of oil and gas — the overall energy we’re able to extract from these resources for every unit of energy we put in — is inexorably declining.
Even coal, the only fossil fuel resource whose EROI has not yet maxed out, is forecast to undergo an EROI peak sometime between 2020 and 2045. This means that while coal might still have signficant production potential in some parts of the world, rising costs of production are making it increasingly uneconomical…
