The Obama administration’s rejection of the Keystone pipeline was predictably stupid and will do little to protect the environment other than by slightly increasing world oil prices. Opponents made it clear that they didn’t care about the negligible environmental impacts of the pipeline; they just wanted to “keep the tar sands in the soil.”
The existence of tar sands refutes the frequent assertion that oil is going to become fantastically expensive in the near future. The Alberta tar sands are estimated to be the second-largest petroleum deposit in the world, but are ignored by those who want “peak oil,” who focus only on the liquid oil that has historically been our main source of petroleum. Extracting liquid oil costs less than extracting tar-sands oil, but since extraction costs form only a fraction of the cost of gasoline, access to tar-sands oil is going to keep gasoline affordable for a long time.
