Fossil fuels accounted for 84% of US energy production in 2023
Fossil fuels—petroleum, natural gas, and coal—accounted for about 84% of total US primary energy production in 2023. This equates to about 4.18 trillion kilowatthours (kWh) of electricity, with coal, oil, and natural gas comprising 82% of the global energy mix. The US remains the world's third-largest consumer of coal, though its consumption has halved in the last decade, leading to a 2.7% decrease in CO2 emissions.
The US has used fossil fuels as its primary energy source for over 100 years, though the mix has changed over time. Petroleum consumption, for example, peaked in the US during the 1970s, with total consumption in 1978 reaching about 49% (38 quads). In 2023, petroleum consumption was about 38% (35 quads).
The burning of fossil fuels has several negative impacts. They are the largest driver of global climate change, producing carbon dioxide (CO2) when burned, and significantly contributing to air pollution, which is linked to millions of premature deaths each year. According to the World Health Organization (WHO), about 99% of people worldwide breathe air that exceeds air quality limits. In 2018, air pollution from fossil fuels caused $2.9 trillion in health and economic costs, or about $8 billion per day.
Despite these negative impacts, fossil fuel consumption has increased significantly over the past 50 years, with consumption in 2022 increasing by 1.5% from 2021. Oil remains the most produced form of energy, though coal consumption is falling in many parts of the world. Cleaner sources of energy are gaining ground, with renewable energy sources now being the cheapest power option in most parts of the world.

Coal, oil and gas make up 82% of the global energy mix
Fossil fuels—coal, oil, and natural gas—accounted for 82% of the global energy mix in 2023. This is a slight increase from the year before, with the world consuming 1.5% more fossil fuels in 2023 than in 2022. Oil and coal made up a third and a quarter of the world's energy consumption, respectively.
Fossil fuels have been the dominant energy source globally for over a century, but the mix has changed over time. For example, while coal consumption is falling in many parts of the world, oil and gas are still growing quickly. In 2019, coal was the dominant fuel for power generation, reaching 37% of global electricity production, with renewables at 27%, natural gas at 24%, and nuclear energy at 10%. Oil provided less than 3% of global electricity in 2019 but was the most produced form of energy that year.
In the United States, fossil fuels accounted for about 84% of total primary energy production in 2023. This has decreased from previous years, such as in 1978 when total petroleum consumption was about 49% of total US energy consumption. In 2023, about 60% of electricity generation was from fossil fuels, with 19% from nuclear energy and 21% from renewable sources.
The burning of fossil fuels is the largest driver of global climate change, and they significantly contribute to air pollution, which is linked to millions of premature deaths each year. As low-carbon sources of energy, such as nuclear and renewables, become more readily available, the world needs to transition away from fossil fuels. The International Renewable Energy Agency estimates that 90% of the world's electricity can and should come from renewable sources by 2050.

Fossil fuels are the largest driver of climate change
Fossil fuels—coal, oil, and natural gas—are the world's primary energy source. In 2023, they comprised 82% of the global energy mix, with coal, oil, and gas accounting for a third, a quarter, and a fifth of the world's energy consumption, respectively. The United States, the world's third-largest consumer of coal, saw fossil fuels make up about 84% of its total primary energy production in 2023, with petroleum, natural gas, and coal being the dominant sources.
The combustion of fossil fuels is the largest driver of climate change. When burned, fossil fuels release large amounts of carbon dioxide, a greenhouse gas, into the atmosphere. Greenhouse gases trap the sun's heat in the atmosphere, causing global warming and, consequently, climate change. The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global carbon dioxide emissions came from fossil fuels and industry.
Coal, the cheapest and dirtiest fossil fuel, is the largest contributor to global temperature rise, responsible for over 0.3°C of the 1°C increase in global average temperatures. Oil, on the other hand, releases approximately a third of the world's total carbon emissions when burned. Natural gas, though promoted as a cleaner energy source than coal and oil, is still a fossil fuel that accounts for a fifth of the world's total carbon emissions.
The burning of fossil fuels for electricity generation and heat production is a significant contributor to global emissions. Most electricity is still generated by burning coal, oil, or gas, which produces carbon dioxide and nitrous oxide—powerful greenhouse gases. The manufacturing and industrial sectors are also major contributors to greenhouse gas emissions, as they burn fossil fuels to produce energy for making cement, iron, steel, electronics, plastics, and other goods.
The effects of climate change due to fossil fuel combustion are already being felt globally. The average global temperature has increased by 1°C, surpassing the critical 1.5°C milestone in 2024. This warming has led to rising sea levels, extreme weather, biodiversity loss, species extinction, food scarcity, and worsening health and poverty for millions worldwide. Warmer temperatures have also disrupted weather patterns, affecting water availability and increasing the risk of agricultural and ecological droughts.

Fossil fuel consumption has increased eight-fold since 1950
Fossil fuels have been the dominant source of energy production for over a century. From 1950 to 2005, fossil fuels provided 85-93% of all energy production. The growth in fossil fuel production since 1950 has been irregular, with rapidly growing per capita production from 1950 to 1980, stable per capita production from 1980 to 2000, and rising per capita production after 2000. This growth has been driven by major increases in coal production in China, India, and Australia, with these three countries accounting for 85% of the growth in world coal production since 1970.
The economic boom in Asia has also played a significant role in the increase in fossil fuel consumption since 1950, with the region's energy consumption rising from 16% to 35% of the world's energy balance. Eastern Europe's share of world energy consumption also doubled during this period, increasing from 10% to 20% due to energy-intensive economic growth.
The largest consumers of fossil fuels use more than ten times the amount of fossil energy than the smallest consumers. In 2023, fossil fuels accounted for 82% of the global energy mix, with coal, oil, and natural gas being the primary sources. The increase in fossil fuel consumption, particularly coal, led to a record high of 40 gigatonnes of carbon dioxide (CO2) emissions, up 2% from 2022.
While there has been a push towards renewable energy sources, fossil fuels still play a significant role in meeting the world's energy demands. In the United States, fossil fuels accounted for about 60% of electricity generation in 2023, with petroleum, natural gas, and coal being the main sources. However, consumption of coal, the largest source of carbon emissions, has halved in the US over the last decade, leading to a significant decrease in CO2 emissions.
