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.

Copper is considered an essential metal for the clean energy transition because it is a great conductor of electricity.
As a result, governments around the world have been encouraging the construction of new mines, and mining companies have been seeking new projects and acquiring existing mines to meet the growing demand.
In this graphic, we illustrate global copper production in 2023, based on data from the U.S. Geological Survey, Mineral Commodity Summaries, as of January 2024.
Most Copper Comes from South America
Chile and Peru account for one-third of the world’s copper output.

🇨🇱 Chile | South America | 5.0 |
🇵🇪 Peru | South America | 2.6 |
🇨🇩 Congo (Kinshasa) | Africa | 2.5 |

Chile is also home to the two largest mines in the world, Escondida and Collahuasi.
Meanwhile, African countries have rapidly increased their production. The Democratic Republic of Congo, for example, transitioned from being a secondary copper producer in the late 1990s to becoming the third-largest producer by 2023.
Part of the growth in copper mining in Africa is attributed to high investment from China. Chinese mining companies represent 8% of Africa’s total output in the mining sector.
Within its territory, China has also seen a 277% growth in copper production over the last three decades.
In the U.S., Arizona is the leading copper-producing state, accounting for approximately 70% of domestic output. Copper is also mined in Michigan, Missouri, Montana, Nevada, New Mexico, and Utah.

In 2023, solar energy accounted for three-quarters of renewable capacity additions worldwide. Most of this growth occurred in Asia, the EU, and the U.S., continuing a trend observed over the past decade.
In this graphic, we illustrate the rise in installed solar photovoltaic (PV) capacity in China, the EU, and the U.S. between 2010 and 2022, measured in gigawatts (GW). Bruegel compiled the data..
Chinese Dominance
As of 2022, China’s total installed capacity stands at 393 GW, nearly double that of the EU’s 205 GW and surpassing the USA’s total of 113 GW by more than threefold in absolute terms.
Installed solar capacity (GW) | China | EU27 | U.S. |
---|---|---|---|
2022 | 393.0 | 205.5 | 113.0 |
2021 | 307.0 | 162.7 | 95.4 |
2020 | 254.0 | 136.9 | 76.4 |
2019 | 205.0 | 120.1 | 61.6 |
2018 | 175.3 | 104.0 | 52.0 |
2017 | 130.8 | 96.2 | 43.8 |
2016 | 77.8 | 91.5 | 35.4 |
2015 | 43.6 | 87.7 | 24.2 |
2014 | 28.4 | 83.6 | 18.1 |
2013 | 17.8 | 79.7 | 13.3 |
2012 | 6.7 | 71.1 | 8.6 |
2011 | 3.1 | 53.3 | 5.6 |
2010 | 1.0 | 30.6 | 3.4 |
Since 2017, China has shown a compound annual growth rate (CAGR) of approximately 25% in installed PV capacity, while the USA has seen a CAGR of 21%, and the EU of 16%.
Additionally, China dominates the production of solar power components, currently controlling around 80% of the world’s solar panel supply chain.
In 2022, China’s solar industry employed 2.76 million individuals, with manufacturing roles representing approximately 1.8 million and the remaining 918,000 jobs in construction, installation, and operations and maintenance.
The EU industry employed 648,000 individuals, while the U.S. reached 264,000 jobs.
According to the IEA, China accounts for almost 60% of new renewable capacity expected to become operational globally by 2028.
Despite the phasing out of national subsidies in 2020 and 2021, deployment of solar PV in China is accelerating. The country is expected to reach its national 2030 target for wind and solar PV installations in 2024, six years ahead of schedule.
