Okay geniuses. Now go look up the "payback ratio" for extracting useable energy from oil sands and oil shale.

And also look up the relationship between reserves and production history. Hint - there is a classic 1949 paper by a Shell geophysicist.

And if you do not know how Canada's reserves and production, and America's imports relate to Mid-East politics...I give up.

Enjoy your little world.
