I've seen a number of comments, both at TheOilDrum and elsewhere, suggesting that the US is now less susceptible to supply disruptions because we have reduced our demand for oil by several hundred thousand barrels per day over the past year. In general, I get the sense that people think we can insulate ourselves from supply disruptions, from our dependence on potentially unreliable foreign sources of oil, by improving our efficiency and eliminating "unnecessary" oil consumption. In my opinion, this is backward. In this post, I will argue that, because the demand that is destroyed first in a free market is the demand that is easiest to eliminate, the resulting consumptive system is more inelastic, more brittle, and more susceptible to systemic shock from supply disruption. I will approach this argument by outlining what makes a system either resilient or brittle and why market-driven demand destruction creates a more brittle system. I will conclude with a few thoughts on how we can increase the resiliency of our energy-driven economy in a future environment of declining energy supplies.

This is a guest post by Phoenix, an engineer working in the energy sector, and a friend of mine for well over 3 decades.

In January 2006 Phoenix emailed me a spreadsheet that predicted an oil price of $100/barrel by 2008, followed by an ongoing geometric rise in oil prices. I remember immediately phoning him to point out that the scenario was impossible because it is unsustainable - $100/barrel would cause economic havoc comparable to the oil shock of the 1970s and if a geometric price progression followed, then no economic recovery would be possible and... well, I recall using the phrase “rioting in the streets inside of 18 months”.

As we know, oil hit $100 in January 2008 and kept climbing, surpassing even Phoenix’s predictions. So when Phoenix offered to explain the model that generated those numbers, I leapt at the opportunity. Here is the story of how Phoenix became Peak Oil aware and generated his Price Calculator.

This isn’t an argument about whether or not taxes—particularly energy taxes—are “good” or “bad.” Rather, this essay has a narrow focus: IF we’re going to attempt to reduce gasoline demand through taxation, what is the best way to do it?

Here’s my somewhat counter-intuitive theory: to most effectively reduce long-term gasoline demand, gasoline taxes should increase, not decrease, long-term price volatility.

First, let’s look at European gasoline taxes. In the UK, gasoline tax is .50 GBP per liter plus 17% VAT ($3.75/gallon before VAT, $4.42/gallon with VAT). In Germany it’s .65 Euro per liter plus 19% VAT ($3.80 per gallon before VAT, $4.53/gallon with VAT). Compare that with US taxes, which range from a low of $0.26/gallon (Alaska) to a high of $0.63/gallon (California). The much higher European taxes operate to reduce price volatility because they remain static in the face of changes in the underlying price of gasoline. For example, if taxes effectively double the price of gasoline, then a 10% increase in the pre-tax gasoline price results in only a 5% increase in the after-tax price of gasoline paid by the consumer.
