Fossil fuels—including coal, oil, and natural gas—have been powering economies for over 150 years and currently supply about 80% of the world's energy. In 2023, fossil fuels accounted for 82% of the global energy mix, with oil and coal dominating the energy market. Oil consumption is largely driven by the transportation sector, while coal is primarily used to generate electricity. The burning of fossil fuels releases carbon and other greenhouse gases into the atmosphere, leading to dramatic changes in Earth's climate. As low-carbon energy sources become more accessible, the world needs to transition away from fossil fuels to mitigate their impact on health and the environment.

What You'll Learn
Fossil fuel consumption by sector
Fossil fuels, including oil, coal, and natural gas, are non-renewable resources that have played a dominant role in global energy systems. While they were key to industrialization, their impact on health and the climate has led to a transition towards low-carbon energy sources.
In the United States, the five energy-use sectors are transportation, industrial, commercial, residential, and electric power. The transportation sector is the largest consumer of primary fossil fuel energy in the US, heavily relying on petroleum-based motor fuels. In 2023, the sector consumed over 26.1 quadrillion British thermal units of fossil fuel energy. Historically, the transportation and electric power sectors consumed more than half of the fossil fuel-produced energy in the country. However, fossil fuel consumption within the electric power sector has been declining in recent years due to a decrease in electricity generation from coal.
The industrial sector is another major consumer of fossil fuels. While coal and oil consumption in this sector are projected to decrease by mid-century, the demand for natural gas is expected to grow. Additionally, industrial uses, including the use of fossil fuels as feedstocks for plastics and ammonia production, are projected to account for 40% of total fossil demand by 2050.
The residential sector, or households, also contributes to fossil fuel consumption. This includes the use of fossil fuels for heating and electricity generation. While fossil fuel use in buildings is expected to decline by mid-century due to efficiency improvements and electrification, non-energy uses of fossil fuels, such as in the production of waxes, solvents, and lubricants, are projected to increase.
To summarize, the transportation, industrial, and residential sectors are significant contributors to fossil fuel consumption. While there is a transition towards low-carbon energy sources, the decline in fossil fuel consumption varies across sectors. Addressing the emissions and methane emissions from the fossil fuel sector is crucial to mitigating climate change and improving human health.

Oil consumption
Other significant uses of oil include the production of electricity and its role as a feedstock in the petrochemical industry. Distillate fuel oil, which includes diesel and heating oil, is the second-most-consumed petroleum product in the US. Diesel fuel is used in various vehicles, heavy construction equipment, and electricity generators. Heating oil is used for heating homes, industrial processes, and power generation.

Coal consumption
Global Coal Consumption
Coal is the leading source of electricity generation worldwide, contributing about 35% of global power generation. As of 2016, the world consumed approximately 8,561,852,178 tons of coal annually, with proven coal reserves equivalent to 133.1 times the annual consumption. Global coal consumption surpassed 164 exajoules in 2023, with China being the largest consumer, accounting for 56% of the global total. India and the United States followed, with 21.98 exajoules and 8.20 exajoules, respectively.
Regional Differences
Regional differences in coal consumption exist, with North America and Europe experiencing a decline since the 1990s. In contrast, the Asia-Pacific region, including China, India, and emerging economies, has seen a surge in demand. China's coal consumption is expected to level off due to the expansion of renewables and increasing electricity demand. India's coal consumption exceeded the combined consumption of Europe and North America for the first time in 2023.
Environmental and Health Impacts
Coal-fired power plants are significant contributors to global carbon dioxide emissions, mercury emissions, and sulfur dioxide emissions, which contribute to climate change and air pollution. The burning of coal releases stored carbon and other greenhouse gases, leading to an excess buildup in the atmosphere and resulting in dramatic changes to the Earth's climate. Additionally, coal power plants generate two-thirds of U.S. sulfur dioxide emissions, contributing to acid rain, and they produce the majority of soot in the air. The health impacts of coal consumption are significant, with air pollution from fossil fuels estimated to cause millions of premature deaths annually.
Transition to Cleaner Energy
There is a growing push toward cleaner energy sources, and many countries are transitioning to renewable energy sources and improving energy efficiency. As of 2023, 84 countries had agreed to phase out coal or not develop new unabated coal power plants, collectively accounting for about 30% of current coal consumption. While coal continues to play a crucial role in electricity generation and industrial processes, the development and deployment of less polluting and more efficient technologies, such as carbon capture and storage, are necessary to reduce its environmental and health impacts.

Gas consumption
Natural gas is projected to meet an increasing share of US energy demand, particularly in the industrial sector, where it is used as a feedstock in chemical processes and for industrial heat and power. However, accessing natural gas requires drilling and a process called hydraulic fracturing, or fracking, which can be extremely resource-intensive and cause local waterway pollution and contaminated wastewater.
The burning of fossil fuels, including natural gas, releases carbon and other greenhouse gases into the atmosphere, contributing to global climate change. In 2020, natural gas was the second-largest source of US energy-related carbon emissions. While generating electricity from natural gas emits less carbon dioxide and other air pollutants than coal, leaks from natural gas plants, wells, and pipelines emit methane, a greenhouse gas that is more effective than carbon dioxide at trapping heat in the atmosphere.

Transitioning to renewable energy
Fossil fuels have been the primary energy source for over 150 years, currently supplying about 80% of the world's energy. Oil, coal, and natural gas have been key to industrialization and rising prosperity. However, their impact on health and the climate means we need to transition to renewable energy sources.
Renewable energy sources are key to a safer, cleaner, and more sustainable world. They are naturally replenished, so we don't have to worry about running out, unlike finite fossil fuel resources. The good news is that renewable energy technologies like wind and solar already exist and are, in most cases, cheaper than fossil fuels.
To successfully transition to renewable energy, we need to address several key factors. Firstly, we need to ensure a robust supply of renewable energy components and raw materials, such as the minerals needed for wind turbines and electricity networks. This will require significant international coordination and investments in sustainable practices. Secondly, global financial systems must commit to accelerating the renewable energy transition by aligning their lending portfolios with renewable energy projects. Thirdly, clear and robust policies, transparent processes, and public support are crucial for accelerating the uptake of wind and solar energy technologies. Finally, we need to address the infrastructure that transmits electricity. As electricity increasingly comes from renewable sources, new infrastructure is needed to connect this energy to where it's needed.
