Canada has vast natural resources and is one of the world’s largest producers and exporters of energy. In 2005, Canada produced 19.1 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 86%, while its total energy consumption has increased by only 48% during that period. Almost all of Canada’s energy exports go to the United States, making it the largest foreign 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.<ref> See Energy Information Administration, [http://www.eia.doe.gov/emeu/cabs/Canada/Background.html "Canada" (2009 report)] </ref>

In 2005, the largest source of energy consumption in Canada was oil (31%), followed by hydroelectricity (25%) and natural gas (24%). Both coal (12%) and nuclear (7%) constitute a smaller share of the country’s overall energy mix. From 1985-2005, Canada’s overall energy mix has remained relatively stable, though hydroelectricity has decreased from 31%to 25%, as oil drilling is more popular than dam building.

From 1985-2005, Canada’s overall energy mix has remained relatively stable, though hydroelectricity has decreased from 31%to 25%, as oil drilling is more popular than dam building. As of 2011, the trend has reversed, and Hydroelectricity is making 32 % of the country's electricity. The remainder is produced by oil, and renewables.
