Canada has considerable natural resources and is one of the world’s largest producers and exporters of energy. In 2006, Canada produced 19.3 quadrillion British Thermal Units (Btu) of total energy, the fifth-largest amount in the world. Since 1980, Canada’s total energy production has increased by 87 percent, while its total energy consumption has increased by only 44 percent. Almost all of Canada’s energy exports go to the United States, making it the largest source of U.S. energy imports. Canada is consistently among the top sources for U.S. oil imports, and it is the largest source of U.S. natural gas and electricity imports. Recognizing the importance of the energy trade between the two countries, both participate in the North American Energy Working Group, which seeks to improve energy integration and cooperation between Canada, the U.S., and Mexico.

In 2006, the largest source of energy consumption in Canada was oil (32 percent), followed by hydroelectricity (25 percent) and natural gas (24 percent). Both coal (10 percent) and nuclear (7 percent) constitute a smaller share of the country’s overall energy mix. From 1986-2006, Canada’s overall energy mix has remained relatively stable, though hydroelectricity has decreased from 31 percent to 25 percent.
