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.

Ranked: Electric Vehicle Sales by Model in 2023
Today, electric vehicle sales make up 18% of global vehicle sales. Here are the leading models by sales as of August 2023.

Ranked: Electric Vehicle Sales by Model in 2023
Electric vehicle (EV) sales are gaining momentum, reaching 18% of global vehicle sales in 2023.
As new competitors bring more affordable options and new performance features, the market continues to mature as customers increasingly look to electric options.
This graphic ranks the top-selling EVs worldwide as of August 2023, based on data from CleanTechnica.
The Best Selling EVs in 2023 (Through August)
Below, we show the world’s best selling fully electric vehicles from January to August 2023:
Model | Country | Vehicles Sold (Jan-Aug 2023) |
---|---|---|
Tesla Model Y | 🇺🇸 U.S. | 772,364 |
Tesla Model 3 | 🇺🇸 U.S. | 364,403 |
BYD Atto 3 / Yuan Plus | 🇨🇳 China | 265,688 |
BYD Dolphin | 🇨🇳 China | 222,825 |
GAC Aion S | 🇨🇳 China | 160,693 |
Wuling HongGuang Mini EV | 🇨🇳 China | 153,399 |
GAC Aion Y | 🇨🇳 China | 136,619 |
VW ID.4 | 🇩🇪 Germany | 120,154 |
BYD Seagull | 🇨🇳 China | 95,202 |
As we can see, Tesla‘s Model Y still holds a comfortable lead over the competition with 772,364 units sold. That’s more than double the sales of the #2 top selling vehicle, Tesla’s Model 3 (364,403)
But it’s hard to ignore the rising prevalence of Chinese EVs. The next five best selling EV vehicles are Chinese, including three from BYD. The automaker’s Atto 3 (or Yuan Plus, depending on market), is being sold in various countries including Germany, the UK, Japan, and India.
Meanwhile, Chinese automaker GAC Group also had two models of its Aion EV brand make the rankings, with the Aion S selling 160,693 units so far.
Regional market strength is also clear. For Volkswagen’s ID.4 model (120,154 units sold), Europe and China account for the majority of sales.
Given growing cost efficiencies and changing consumer behavior, global EV sales are projected to make up half of new car sales globally by 2035, according to forecasts from Goldman Sachs.
