Mapped: Biggest Sources of Electricity by State and Province

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 Island90.9
🇺🇸 Delaware85.8
🇺🇸 Massachusetts76.9
🇺🇸 Florida73.9
🇺🇸 Mississippi72.1

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 Labrador95
🇨🇦 Quebec94
🇨🇦 British Columbia87
🇨🇦 Yukon80
🇺🇸 Washington65
🇺🇸 Idaho51
🇺🇸 Vermont50
🇨🇦 Northwest Territories 47
🇺🇸 Oregon46

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.

Key Takeaways

  • Fossil fuels made up nearly 60% of 2024 electricity generation.
  • Coal accounts for 35% of total power generation.

Fossil Fuels Still Power Most of the World

Global energy demand grew faster than average in 2024, driven by rising electricity use across sectors. The power sector led the surge, with demand growing nearly twice as fast as overall energy use—fueled by increased cooling needs, industrial activity, transport electrification, and the expansion of data centers and AI.

Despite a growing push toward cleaner energy sources, coal remains the leading source of electricity generation worldwide. In 2024, fossil fuels accounted for nearly 60% of global power generation, with coal alone contributing 35%, according to the International Energy Agency.

While renewable energy continues to expand, making up about one-third of total electricity production, the global energy mix still leans heavily on traditional sources.

🌍 Global34.5%21.8%2.4%32.1%9.1%

In emerging markets and developing economies, coal continues to be the backbone of power systems. China, the world’s largest energy consumer, generated nearly 60% of its electricity from coal. In India, coal’s dominance is even more pronounced, providing close to three-quarters of all electricity produced.

In contrast, advanced economies are increasingly relying on cleaner sources. In 2024, the European Union made significant strides in renewable energy adoption—nearly half of its electricity came from renewables, far exceeding the global average.

In the United States, natural gas led the power mix, accounting for over 40% of electricity generation in 2024. President Trump’s pro-coal policies and the surge in energy demand from AI innovation are expected to boost coal production in the U.S. over the next few years.

Since the war in Ukraine began on February 24, 2022, Russia has earned $915 billion from fossil fuel exports, with EU countries accounting for over $223 billion.

Despite sanctions against Moscow, the EU remains a key consumer of Russian fossil fuels.

This graphic highlights the largest importers of Russian fossil fuels, based on the daily flow of oil and gas, using data from the CREA Fossil Fuel Tracker as of March 2025.

China Becomes the Biggest Buyer

In June 2022, China overtook the EU as the largest importer of Russian fossil fuels. Today, China imports nearly six times more than the EU. India and Turkey have also emerged as major buyers.

Meanwhile, imports from the U.S. and UK, which were relatively small before the invasion, have dropped to zero.

EU Reliance on Russian Fuel

A report released by Ember estimates that European purchases of Russian gas amounted to €21.9 billion ($23.6 billion) in 2024.

Additionally, data collected by Kpler and analyzed by POLITICO Europe revealed that in the first 15 days of 2025, the 27 EU countries imported a record-high 837,300 metric tons of liquefied natural gas (LNG) from Russia. This has raised concerns that billions of dollars could be fueling Moscow’s war in Ukraine.

Russia’s Position in Global Oil Production

Russia remains one of the world’s top oil producers, frequently competing with Saudi Arabia for the second spot behind the United States.

Following the fall of the Soviet Union, Russia’s oil industry was privatized, but in 2021, the state forced a consolidation and restructuring of the sector. Today, Gazprom, Rosneft, and Lukoil are Russia’s leading oil and gas producers.
