Global oil depletion is not immune to the Law of Receding Horizons, the Law of Diminishing Marginal Returns, nor it seems to the Law of Unintended Consequences. The Grangemouth refinery shutdown has apparently caused work on a new wind farm in Scotland to shut down for lack of diesel fuel. Though at this stage this is a short-term snafu, it's a real time example of how lack of systems analysis of our energy problem will lead to unanticipated problems.

Tomorrow we will highlight another in a series of analysis on Energy Return on (Energy) Investment. Though measuring an energy projects profit and cost in terms of energy is very important, all energy sources are not the same, and the word 'alternative' does not connote 'equality'. In effect, quality matters. Despite some attractive substitutes to oil and gas from an energy return perspective, ALL fuel sources are now heavily subsidized by an infrastructure built and maintained by cheap and constantly available liquid fuels.
