"The U.S. Environmental Protection Agency says TransCanada Corp. should be required to buy renewable power to run pumps along the route of its proposed Keystone XL pipeline, a measure the company said is unworkable and unnecessary."

"In a July 17 letter to the U.S. State Department, the Calgary-based company said the EPA suggested it buy renewable energy to run pumping stations from Alberta to Steele City, Nebraska. The EPA, in an April filing with the State Department, also said the U.S. should work with Canada to promote technology to capture and store underground the carbon-dioxide emissions generated in the production of Canadian oil.

'Keystone does not control the source of the power it purchases,' according to the letter, released yesterday by the company. 'TransCanada has invested over $5 billion in emission-less energy sources including the largest wind farm in Maine and 13 hydro power stations in the U.S. Northeast.'"
