Fossil fuels generate 18% of Canadian electricity, about half as coal (7% of the total) and the remainder a mix of natural gas and oil. Only four provinces use coal for electricity generation. Alberta, Saskatchewan, New Brunswick, and Nova Scotia rely on coal for less than half their generation while other provinces and territories burn none for electricity. Alberta and Saskatchewan also use a substantial amount of natural gas. Remote communities including all of Nunavut and much of the Northwest Territories produce most of their electricity from diesel generators, at high economic and environmental cost. The federal government has set up initiatives to reduce dependence on diesel-fired electricity. However, in 2018, the NWT generated 70% of their electricity from hydroelectric dams and 4% from wind. In Nunavut, solar generates a small amount of electricity though small installations and projects.
