The Post-Carbon Institute has been raising awareness of energy-related policy issues since 2003. This is a critical task: our current way of life, which is based on cheap and abundant energy, is inevitably going to have to change, and change soon – because energy supplies are becoming scarcer, and ever more expensive (PDF). This isn’t because we’re running out of oil: it’s because discovering and extracting oil is becoming so expensive that a price high enough to keep oil companies in business is a price that’s too high for consumers to afford. If the price goes down, the producers go bust; if the price goes up, the consumers go bust. That’s where we are now, and for evermore, because there are no new sources of cheap oil.
