Two more ethical challenges to Canada’s oil sands
Since the turn of the century, light oil, the highest quality hydrocarbon, has given civilization extraordinary energy gains and fueled all the trappings of modern life. But the rapid development of bitumen, one of the world’s most expensive and heaviest hydrocarbons, has clearly signaled the end of cheap oil. Like most unconventional fuels, bitumen takes more energy to make than conventional oil. In fact, bitumen production requires so much natural gas for processing and enrichment that it now accounts for one-fifth of Canada’s natural gas demand. The extravagant use of natural gas to produce a lower grade fossil fuel is unprecedented.
