Could declining world energy result in a turn toward authoritarianism by governments around the world? As we will see, there is no simple answer that applies to all countries. However, pursuing the question leads us on an illuminating journey through the labyrinth of relations between energy, economics, and politics.
The International Energy Agency and the Energy Information Administration (part of the U.S. Department of Energy) anticipate an increase in world energy supplies lasting at least until the end of this century. However, these agencies essentially just match supply forecasts to anticipated demand, which they extrapolate from past economic growth and energy usage trends. Independent analysts have been questioning this approach for years, and warn that a decline in world energy supplies—mostly resulting from depletion of fossil fuels—may be fairly imminent, possibly set to commence within the next decade.
Even before the onset of decline in gross world energy production we are probably already beginning to see a fall in per capita energy, and also net energy—energy that is actually useful to society, after subtracting the energy that is used in energy-producing activities (the building of solar panels, the drilling of oil wells, and so on). The ratio of energy returned on energy invested (EROEI) for fossil energy production has tended to fall as high-quality deposits of oil, coal, and natural gas are depleted, and as society relies more on unconventional oil and gas that require more energy for extraction, and on coal that is more deeply buried or that is of lower energy content. Further, renewable energy sources, especially if paired with needed energy storage technologies, tend to have a lower (some say much lower) EROEI than fossil fuels offered during the glory days of world economic growth after World War II. And renewables require energy up front for their manufacture, producing a net energy benefit only later on.
