For those who foolishly believe the age of oil is over, consider what would be happening right now if Michigan Gov. Gretchen Whitmer had succeeded in shutting down Enbridge’s Line 5 pipeline on Wednesday, as she has been demanding. Half of the oil supplied to Ontario and Quebec, and half of the propane supplied to Michigan, would be choked off. Up to 800 tanker rail cars and 2,000 trucks per day would be needed to transport 540,000 barrels of oil and liquefied natural gas, now supplied by Line 5, since the demand for energy would still be there even if the pipeline wasn’t. Industrial greenhouse gas emissions and air pollution in both Canada and the U.S. would increase. Tens of thousands of direct and indirect jobs would be at immediate risk on both sides of the border, in Canada’s case most severely in Sarnia.
