Fossil fuel consumption by country
Fossil fuels, including oil, coal, and natural gas, are the world's dominant energy source, accounting for over 90% of carbon dioxide emissions. While renewable energy is experiencing rapid global growth, fossil fuel consumption reached new record highs in 2023. This was largely driven by China and the US, which together were responsible for almost half (47%) of global fossil fuel consumption. China consumed 140 exajoules of fossil fuels, while the US consumed 76 exajoules. India was the third-largest consumer at 35 exajoules.
The US is the world's largest oil consumer, with over 19.1 million barrels consumed per day in 2022. In the same year, the US consumed 32.2 trillion cubic feet of natural gas. Oil is also the primary energy source in South Korea, which imported 960 million barrels of crude oil in 2021. Korea was the seventh-largest global energy consumer in 2022 and has set a target of reaching carbon neutrality by 2050.
Russia is a prominent player in the oil market, producing roughly 11.28% of the world's oil in 2021. In the same year, it consumed 3.67 million barrels daily, accounting for 4% of global consumption. Russia is also one of the largest consumers of natural gas, with 408 billion cubic meters consumed in 2022. Japan, despite its relatively small territory, ranks fifth in fossil fuel consumption. In 2022, Japan consumed over 151 million metric tons of oil and imported 180.3 million tons of coal.
Canada, with its heavy reliance on oil for transportation and industry, consumed upwards of 98 million metric tons of oil in 2022. Canada also consumes notable amounts of coal and natural gas, and it aims to achieve net-zero emissions by 2050 through increased use of hydro, wind, and solar power.
Per capita fossil fuel consumption is highest in Equatorial Guinea, Estonia, Singapore, Qatar, Trinidad and Tobago, the United Arab Emirates, and Kuwait. These countries consume 10 or more tons of fossil fuels per person per year.

Fossil fuel consumption per person
In 2021, the world consumed approximately 97 million barrels of oil per day. This figure, when viewed in the context of global population, provides a metric for average per capita fossil fuel consumption. However, it is important to note that this figure does not account for the various types of fossil fuels and their differing impacts.
Coal, oil, and natural gas are the primary sources of fossil fuel energy. Coal is the most polluting energy source in terms of CO2 emissions and local air pollution. Oil accounts for a small share of electricity production, with most fossil-fuel-derived electricity coming from coal and natural gas.
When fossil fuels are burned, they release carbon dioxide (CO2), the most significant greenhouse gas contributing to global warming and climate change. The burning of fossil fuels also produces local air pollutants, which have been linked to millions of premature deaths annually. As such, transitioning away from fossil fuels towards low-carbon energy sources is imperative for mitigating climate change and improving public health.
Per capita fossil fuel consumption varies significantly across countries, with the largest consumers using more than ten times the amount of fossil energy than the smallest consumers. This variation is influenced by factors such as population size, economic development, and access to alternative energy sources. Examining these country-specific consumption patterns provides insights into the global energy landscape and the disparate impacts of fossil fuel usage.

Fossil fuel reserves
Fossil fuels, including coal, oil, and natural gas, have been the primary energy source since the Industrial Revolution. However, burning these fuels releases carbon dioxide (CO2), a greenhouse gas contributing to global warming and climate change. As a result, there is a growing need to transition to low-carbon energy sources and reduce fossil fuel consumption.
The world consumed nearly 97 million barrels of oil per day in 2021. Oil, however, accounts for only a small share of electricity production, with most electricity generated from coal and natural gas. Coal is the world's dirtiest fuel, emitting the most CO2 per unit of energy and severely impacting health through air pollution. Many countries are committing to phasing out coal power, with some already coal-free and others setting targets for elimination by 2030 or 2040.
The distinction between "reserves" and "resources" of fossil fuels is essential when discussing fossil fuel reserves. "Proven reserves" refer to fossil fuels that can be recovered in the future with reasonable certainty under existing economic and technological conditions. In other words, we know they are there, and it would be technologically and economically feasible to extract them. However, reserves only represent a fraction of resources, as new quantities of fossil fuels are discovered, and advancements make more resources extractable. Thus, the amount of reserves changes over time due to consumption and the unlocking of new resources.
According to the 2015 Paris Agreement, a sharp decline in fossil fuel use is necessary to limit global warming to well below 2°C and pursue a 1.5°C target. By 2050, nearly 60% of oil and fossil methane gas and 90% of coal must remain unextracted to meet the 1.5°C carbon budget. This requires a global decline in oil and gas production of 3% annually until 2050, rendering many current and planned fossil fuel projects unviable.

Fossil fuel production
Fossil fuels, including coal, oil, and gas, have been a significant source of energy for human civilization. The burning of fossil fuels releases carbon dioxide (CO2), contributing to global warming, climate change, and air pollution. While there has been a growing movement towards renewable energy sources, fossil fuel production and consumption remain prevalent worldwide. This response will provide an overview of fossil fuel production and its associated impacts.
Historical Context
The use of fossil fuels has a long history, with peat serving as a domestic fuel even before recorded history. Coal was also utilized in early furnaces for metal ore smelting, while semi-solid hydrocarbons from oil seeps were employed for waterproofing and embalming. The Industrial Revolution marked a significant shift, as the burning of fossil fuels became a major energy source, driving economic growth and industrialization.
Production and Consumption Trends
Coal dominated the fossil fuel landscape until the 20th century, when the emergence of automobiles, the petrochemical industry, marine shipping, and air travel led to a surge in oil demand. Natural gas gained prominence after World War II, and by the early 2020s, it accounted for nearly half of US fossil fuel production. Globally, oil consumption reached nearly 97 million barrels per day in 2021.
Country-Level Variations
Environmental and Health Impacts
The burning of fossil fuels has detrimental environmental and health consequences. In addition to releasing CO2, it contributes to atmospheric particulate matter, smog, and acid rain, and the release of radioactive materials like uranium and thorium. Air pollution from fossil fuels has been associated with millions of premature deaths annually, and the economic cost is substantial, estimated at US$2.9 trillion in 2018.
Transition to Renewable Energy
Recognizing the negative impacts of fossil fuels, many countries have pledged to achieve net-zero emissions and transition to renewable energy sources. However, there is a disconnect between these commitments and the continued support for fossil fuel production, highlighting the challenges in aligning policies with the urgent need to address climate change.

Fossil fuel alternatives
Fossil fuels, including coal, oil, and gas, are the world's primary energy source. In 2021, the world consumed nearly 97 million barrels of oil per day. However, fossil fuels have several negative impacts. When burned, they produce carbon dioxide (CO2) and are the largest driver of global climate change and local air pollution. As low-carbon sources of energy, such as nuclear and renewables, become more readily available, the world needs to transition away from fossil fuels.
Renewable Energy
Renewable energy sources, such as wind, solar, tidal, and hydroelectric power, are infinite, unlike fossil fuels, which will eventually run out. While renewable energy sources are dependent on external factors such as wind, sunlight, and water levels, they offer a reliable source of energy when these conditions are met. Solar energy, in particular, has gained popularity as an alternative to fossil fuels due to its ability to convert sunlight into electricity.
Nuclear Power
Nuclear power is derived from controlled nuclear fission, or the splitting of uranium atoms, in power stations. While nuclear power has been identified as a low-carbon source of energy, it is not considered a renewable energy source.
Hydrogen
Hydrogen is a potentially emissions-free alternative fuel that can be produced from renewable resources and used in fuel cell electric vehicles, such as cars, trucks, ships, and even aircraft.
Biomass
Biomass refers to biological material that is either living or decaying, including wood, plant, forest residues, and compost material. Some crops, such as rapeseed, are specifically grown as biofuels. While burning biomass produces greenhouse gases, it is still a viable alternative to fossil fuels, particularly for coal-fired plants aiming to reduce emissions.
Geothermal Energy
Geothermal energy is derived from the Earth's natural sources of heat, primarily volcanic activity. This energy source is currently used to generate 30% of Iceland's electricity, utilizing thermal springs heated by molten rock located thousands of meters below the surface. However, geothermal energy is limited to areas with volcanic sources.
