What You'll Learn
Fossil fuel consumption by type
Fossil fuel consumption has increased significantly over the past half-century, with a roughly eightfold increase since 1950 and a doubling since 1980. The types of fuel consumed have shifted from solely coal towards a combination of coal, oil, and natural gas.
In 2023, fossil fuels comprised 82% of the global energy mix, with oil and coal dominating. Oil and coal accounted for a third and a quarter of the world's energy consumption, respectively. Gas, the second-largest source of electricity production globally, is also a significant contributor to the global energy mix. While its use is growing quickly in many countries as a substitute for coal, it still emits CO2 and contributes to climate change.
In the United States, fossil fuels have dominated the energy mix for over a century, though the mix has changed over time. In 2023, petroleum accounted for about 38% of total US energy consumption, down from a peak of 49% in the 1970s. The US remains the world's third-largest consumer of coal.
While fossil fuels play a dominant role in global energy systems, they have negative impacts on health and the climate. When burned, they produce carbon dioxide (CO2) and are the largest driver of global climate change. They also contribute to local 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 transition away from fossil fuels is crucial for mitigating climate change and improving human health.

Fossil fuel consumption by country
The United States, China, and India are among the top consumers of fossil fuels globally. In 2022, the US consumed over 19.1 million barrels of oil per day and 32.2 trillion cubic feet of natural gas. China consumed 140 exajoules of fossil fuels in 2023, mainly coal, accounting for 56% of global coal consumption. India, the third-largest consumer, consumed 35 exajoules of fossil fuels in 2023. These three countries alone account for almost half of the world's fossil fuel consumption.
Other countries with significant fossil fuel consumption include Japan, Russia, Canada, and South Korea. Japan, with its relatively small territory, ranks fifth in fossil fuel consumption, consuming over 151 million metric tons of oil and importing 180.3 million tons of coal in 2022. Russia is a prominent player in the oil market, consuming 3.67 million barrels daily in 2021, and is also a large consumer of natural gas, with 408 billion cubic meters consumed in 2022. Canada, heavily dependent on oil, consumed upwards of 98 million metric tons of oil in 2022, along with considerable amounts of coal and natural gas. South Korea, where oil is the primary energy source, imported 960 million barrels of crude oil in 2021 and was the third-largest LNG importer globally.
It is worth noting that some smaller countries have high per capita fossil fuel consumption. For example, Equatorial Guinea, Estonia, Singapore, and Qatar all consume more than 10 tons of fossil fuels per person annually, with Equatorial Guinea leading at 18 tons per person. These countries often produce a significant amount of fossil fuels themselves.
While fossil fuel consumption remains high in many countries, there is a growing trend towards renewable energy sources. Countries like Canada, South Korea, and Germany are making efforts to transition to cleaner energy sources and achieve carbon neutrality by 2050.

Fossil fuel consumption over time
Fossil fuel consumption has increased significantly over the past few centuries. The burning of fossil fuels for energy began around the Industrial Revolution. Since 1950, global fossil fuel consumption has increased eightfold and roughly doubled since 1980. However, the types of fuel used have shifted from solely coal towards a combination of oil and gas.
Coal has been a critical energy source and mainstay in global energy production for centuries. However, it is also the most polluting energy source in terms of CO2 emissions and local air pollution. In 2023, coal, oil, and natural gas comprised 82% of the global energy mix, with oil and coal accounting for a third and a quarter of the world's energy consumption, respectively. The record consumption was driven by a spike in energy demand, more than half of which came from the Global South, where energy demand is growing at twice the global rate.
Despite the negative impacts of coal on the environment and human health, it remains a significant source of energy in many parts of the world. In 2023, the US, the world's third-largest consumer of coal, saw a decrease in petroleum consumption, largely due to the response to the COVID-19 pandemic. However, consumption increased in subsequent years as the economy returned to pre-pandemic activity.
While renewable energy sources accounted for 15% of the global energy mix in 2023, the highest share in history, fossil fuels still dominated, with global primary energy consumption hitting historic highs. The transition to renewable energy sources has been slow, and the share of energy coming from fossil fuels has remained relatively unchanged.
Nuclear energy has also played a role in global energy consumption, with its share of US energy consumption peaking in 2020 at about 9%. However, the number of operating nuclear reactors has declined since the 1990s, impacting nuclear energy production.

Fossil fuel production
Oil consumption constitutes about one-third of US energy consumption and is the largest source of energy-related carbon emissions. The transportation sector accounts for most oil consumption, and oil is also a major source of greenhouse gas emissions. In 2020, oil combustion was responsible for 45% of US energy-related carbon dioxide emissions. While there was a drop in oil production and consumption in 2020 due to the COVID-19 pandemic, a return to 2019 levels is expected in the coming years.
Coal has been a critical energy source and mainstay in global energy production for centuries, but it is also the most polluting energy source in terms of CO2 emissions and local air pollution. Coal combustion produces a variety of air pollutants, including sulfur dioxide, nitrogen oxides, mercury, and particulate matter. In 2023, coal consumption led to 40 gigatonnes of CO2 emissions, the highest level ever recorded. As a result, many countries are transitioning away from coal towards natural gas and renewable energy sources.
Natural gas is increasingly being used to generate electricity and now supplies one-third of US energy consumption. In 2020, the US produced and consumed about 24% and 22% of the world's natural gas, respectively. While natural gas emits less CO2 per unit of energy than coal, the ultimate goal is to shift towards low-carbon sources such as renewables and nuclear energy.
The burning of fossil fuels has significant negative environmental impacts, including the release of CO2 and other greenhouse gases, contributing to climate change and air pollution. Fossil fuel phase-out is a proposed gradual global reduction of fossil fuel use and production to address these issues and strengthen energy independence.
