People also forget to think that one of the biggest inputs for extracting the oil out of the bitumen is... natural gas and oil... more specifically, oil and gas is burned to create steam which is sent into the ground. If oil prices are high like they are now, it exacerbates the economic viability issue. This is mainly to do with the oilsands however.
