Inside the Keystone Pipeline: How Much Would it Really Help US Consumers?
from the Christian Science Monitor
Often lost in the political wrangling over the controversial Keystone XL pipeline--on hold after President Obama rejected TransCanada's initial construction proposal--are some key findings that run counter to the rosy picture of abundant supply and lower prices so often painted by US politicians.
Canadian companies backing the Keystone XL--touted as enhancing US energy security with a big new surge of imported Canadian oil--actually expect it to supply more lucrative Gulf Coast export markets as well as raise Midwest oil prices by reducing "oversupply" in that region.
These little-publicized findings are contained in the studies and testimony of experts working for TransCanada, the company that wants to build the pipeline from Alberta's tar sands across America's heartland to Gulf Coast refineries.
