Canadian Primary energy production in 2020, including uranium, declined from 2019 by 2,490 petajoules, which was a 10% reduction.
The majority of Canadian energy production and consumption relies on fossil fuels, similar to the rest of the world. From 2019 to 2020 hydropower and other renewables increased their shares of total production marginally, as did natural gas and crude oil, at the expense of nuclear and coal. However, Canada continues to have one of the lowest greenhouse gas-emitting electricity systems in the world, with 80% of electricity produced from non-emitting sources.
