Canada is the United States’ largest partner for energy trade

Canada is the largest energy trading partner of the United States. Based on the latest annual data from the U.S. Census Bureau, energy accounted for about 5% of the value of all U.S. exports to Canada and more than 19% of the value of all U.S. imports from Canada in 2016.

"The U.S., on the other hand, gets close to 50 per cent of its energy from coal-fired generating stations.
Canada's extensive power grid offer a stable source of clean electricity for many northern states. By purchasing this energy, as opposed to building more coal plants, the U.S. is working towards its goal of reducing greenhouse gas emissions."
Not anymore! Trump decide to build more coal plants , Making America Great again..... LOL
