U.S. 'dirty oil' imports set to triple

NEW YORK (CNNMoney) -- U.S. imports of what environmentalists are calling "dirty oil" are set to triple over the next decade, raising concerns over the environmental impact of extracting it and whether pipelines can safely transport this Canadian oil.
The United States currently imports over half a million barrels a day of bitumen from Canada's oil sands region, according to the Sierra Club. That number, Sierra Club says is set to grow to over 1.5 million barrels by 2020. That represents nearly 10% of the country's current consumption.
The U.S. Energy Information Administration's overall Canadian oil production numbers are in-line with the Sierra Club's projected pace.
Bitumen is a heavy, tar-like oil. It needs to be heavily processed in order to be turned into more viscous, easier to refine, crude oil. Because it's so thick, to make it more viscous and move it by pipeline, it gets diluted with natural gas liquids.
