If we acknowledge that the Soviet Union had a powerful economy, which it did, and acknowledge that its economy was based on the same abundant, high quality energy that the US depended on, oil, then the reason for the fall is clear—peak oil. The fall of the Soviet Union is a peak oil event and if we treat it as such, then we can begin to understand what is in store for our own economy. Indeed, the fall of the Soviet Union is a perfect economic experiment for what will happen to our own world economy as peak oil continues.
According to the Economist (2010), the world is experiencing a rising cost for extracting energy because the energy needed to extract energy is rising, i.e. this is the concept of a falling Energy Return on Energy Investment (EROI). See Cleveland et. al. (1984), Hall et. al. (1986) and Hall (2008). What is more the Economist finally says what so many others, like Hamilton (1983), have been saying for years, that energy costs are affecting the economy. A decreasing EROI is in turn a general way to explain peak oil as it implies you can no longer find high EROI energy, e.g. conventional oil in large reservoirs but are instead finding low EROI oil, such as oil in small reservoirs. The decreasing EROI also implies another problem for the economy because the substitution away from high EROI oil is increasingly inelastic (Reynolds 1999c) and creates a loss of the Entropy Subsidy (Reynolds 1998). In other words, peak oil will cause economic decline. However, if peak oil is affecting the world, than why would it not have affected the Soviet Union too? Clearly it did.
No one has studied closely the Soviet Union’s EROI to see, like our current world economies, if EROI was declining within the Soviet system and therefore affecting the Soviet economy. Nevertheless, one way to analyze the fall of the Soviet Union is to simply analyze its conventional oil use, which has been studied, see Reynolds and Kolodziej (2007 and 2008) and Reynolds (2009, 2001, and 1999a)
