Mapped: Biggest Sources of Electricity by State and Province


On a national scale, the United States and Canada rely on a very different makeup of sources to generate their electricity.

The U.S. primarily uses natural gas, coal, and nuclear power, while Canada relies on both hydro and nuclear. That said, when zooming in on the province or state level, individual primary electricity sources can differ greatly.

Here's a look at the electricity generation in the states and provinces of these two countries using data from the Nuclear Energy Institute (2021) and the Canada Energy Regulator (2019).

Natural Gas


Natural gas is widely used for electricity generation in the United States. Known as a "cleaner" fossil fuel, its abundance, coupled with an established national distribution network and relatively low cost, makes it the leading electricity source in the country.

In 2021, 38% of the 4120 terawatt-hours (TWh) of electricity generated in the U.S. came from natural gas. Not surprisingly, more than 40% of American states have natural gas as their biggest electricity source.

Here are some states that have the largest shares of natural gas-sourced electricity.

State/Province % of Electricity from Natural Gas
Rhode Island 90.9
Delaware 85.8
Massachusetts 76.9
Florida 73.9
Mississippi 72.1

In Canada, natural gas is only the third-biggest electricity source (behind hydro and nuclear), accounting for 11% of the 632 TWh of electricity produced in 2019. Alberta is the only province with natural gas as its main source of electricity.

Nuclear

Nuclear power is a carbon-free energy source that makes up a considerable share of the energy generated in both the U.S. and Canada.

19% of America's and 15% of Canada's electricity comes from nuclear power. While the percentages are close to one another, it's good to note that the United States generates 6 to 7 times more electricity than Canada each year, yielding a lot more nuclear power than Canada in terms of gigawatt hours (GWh) per year.

As seen in the map, many states and provinces with nuclear as their main source of electricity are concentrated in the eastern half of the two countries.

In the U.S., Illinois, Pennsylvania, and South Carolina are top producers in terms of GWh/year. Illinois and South Carolina also have nuclear as their primary electricity source, whereas Pennsylvania's electricity production from natural gas exceeds that from nuclear.

The vast majority of Canada's nuclear reactors (18 of 19) are in Ontario, with the 19th in New Brunswick. Both of these provinces rely on nuclear as their biggest source of electricity.

Renewables: Hydro, Wind and Solar

Out of the different types of renewable electricity sources, hydro is the most prevalent in North America. For example, 60% of Canada's and 6% of the U.S.'s electricity comes from hydropower.

Here are the states and provinces that have hydro as their biggest source of electricity.

State/Province % of Electricity from Hydro
Manitoba 97
Newfoundland and Labrador 95
Quebec 94
British Columbia 87
Yukon 80
Washington 65
Idaho 51
Vermont 50
Northwest Territories 47
Oregon 46

Wind and solar power collectively comprise a small percentage of total electricity generated in both countries. While no state or province relies on solar as its biggest source of electricity, Iowa, Kansas, Oklahoma, and South Dakota rely primarily on wind for their electricity, along with Canada's Prince Edward Island (PEI).

Coal and Oil

Coal and oil are emission-heavy electricity sources still prevalent in North America.

Currently, 22% of America's and 7% of Canada's electricity comes from coal, with places such as Kentucky, Missouri, West Virginia, Saskatchewan, and Nova Scotia still relying on coal as their biggest sources of electricity.

Certain regions also use petroleum to generate their electricity. Although its use for this purpose is declining, it is still the biggest source of electricity in both Hawaii and Nunavut.

Over the next few years, it will be interesting to observe the use of these fossil fuels for electricity generation in the U.S. and Canada. Despite the differences in climate commitments between the two countries, lowering coal and oil-related emissions may be a critical part of hitting decarbonization targets in a timely manner.

I reside in that big blue place called Quebec were energy is abundant and relatively cheap.

my favorite part of canada, from an I've only been to quebec city perspective...

I live where we burn coal, but produce more natural gas and oil, colorado. it's always pretty funny when the wealthy conservative land owners that lease to wind generation in the east part of the state remain quiet when local GOP anti-sustainable energy legislation is the topic. electrical energy consumers here are still paying for a poorly constructed (flawed) nuke generator that hasn't produced enough energy to keep it's own lights on in decades. this state also has a past history of being bent over by big oil. luckily there seems to be enough holes in the ground now that the major players moved on a couple years ago.

Looks like if one looks , its an all of the above situation really dependent on whats locally available .

my state of Wyoming depends on coal/ Ng predominantly , but they have crude oil , Ng wind  and hydro capability as well as uranium deposits .

What i think happens here is they go with the cheapest to acquire , and sell off to others  that dont have those resources or deposits .

 example , the crude here is refined as diesel /home heating oil and sold , i was surprised to find out the biggest purchaser of it was California . NG is piped south and back east for the most part if it isnt used locally  .

 As for the uranium , well the government actually controls that for the most part .

Here we had the billion dollar boondoggle from the so called clean air coal plant.

They finally shut it down and made it gas....

My Sister owns her house on a street that has no gas lines down it, so everything in her house is electric. If they wanted gas they would have had to pay themselves to run the gas lines down the street. It would have cost them 10 to 20 k to get the lines down to them.

So a  no go...

The only problem they have run in to was when they wanted to get an on demand water heater. Apparently the electric ones would have required them to redo the wiring in the house for the demand it would have put on them. Would have to rewire and add breakers or something.

They finally said screw it and went back to a tank.
