Canada's Oil Sand

The Athabasca oil sands deposit is among the largest in the world. The bitumen, also commonly named tar (hence tar sands), contains lots of hydrocarbons, but is notoriously hard to extract. For every 100 BTU of energy extracted, 70 BTU is lost in the process. In 2011 alone, the oil sands operations in Canada produced 55 million tons of ‘greenhouse gas emissions’. That’s eight percent of Canada’s total emissions.
