Fossil fuels account for 84% of US energy production
Fossil fuels have long been the primary source of energy in the United States, and this trend continues today. In 2023, fossil fuels accounted for approximately 84% of total US energy production, a figure that has remained relatively consistent over the past three decades. This percentage translates to about 77.2 quadrillion British thermal units (Btu) of energy derived from fossil fuels, with coal, oil, and natural gas being the three major forms.
The United States is a significant producer and consumer of energy, second only to China in terms of electricity consumption. In 2023, the country's total primary energy consumption was about 94 quadrillion Btu, with fossil fuels contributing to the majority of this demand. Fossil fuels are used across various sectors in the US, with transportation being a major consumer. Petroleum, in particular, provided about 89% of the transportation sector's primary energy consumption in 2023, while also playing a crucial role in the petrochemical industry and the production of plastics.
Natural gas has gained prominence within the fossil fuel landscape, becoming the top fossil fuel source in 2016. Its use is projected to increase further, especially in the industrial sector. However, natural gas plants, wells, and pipelines can leak methane, a potent greenhouse gas. Coal, another major fossil fuel, has seen a decline in usage due to its higher emissions compared to natural gas. Nevertheless, coal still accounted for a significant share of US energy production in 2023, with a notable impact on electricity generation.
While renewable energy sources are growing in importance, fossil fuels continue to dominate the US energy landscape. In 2018, fossil fuels met about 80% of the nation's energy demand, and even with the growth of renewables, fossil fuels still accounted for 60% of electric generation in 2023. The transition away from fossil fuels is crucial due to their environmental impact, particularly the release of carbon dioxide and other greenhouse gases when burned.

Oil is the largest source of US carbon emissions
In the US, oil is the largest contributor to carbon emissions, followed by gas. Oil and gas are responsible for a greater proportion of emissions in developed nations, whereas solid fuels, such as coal, are more dominant in developing nations like China and India. The US has seen a significant decline in coal production in recent decades due to energy transitions.
The transportation sector is the largest source of direct greenhouse gas emissions in the US, with over 94% of the fuel used for transportation being petroleum-based, including gasoline and diesel. The transportation sector accounted for the largest share of US energy end-use CO2 emissions in 2023. In 2023, petroleum accounted for about 38% of US energy consumption and was the source of 47% of total annual US carbon emissions.
While renewable energy sources are growing in the US, fossil fuels still dominate the country's energy mix. In 2018, fossil fuels met about 80% of the nation's energy demand, down from 84% a decade earlier. Crude oil and natural gas production have increased dramatically in recent years due to new technologies like fracking and horizontal drilling.

Natural gas is the most common fuel type for electricity generation
In 2023, about 4,178 billion kilowatt-hours (kWh) of electricity were generated at utility-scale electricity generation facilities in the United States. Fossil fuels, including coal, natural gas, petroleum, and other gases, accounted for approximately 60% of this electricity generation. Notably, natural gas was the top source of U.S. utility-scale electricity generation, contributing about 43% of the total.
Natural gas has become the most common fuel type for electricity generation in the United States, surpassing coal, which was once the dominant source. In 2018, natural gas accounted for about a third of total energy production in the country. The shift towards natural gas can be attributed to the advancement and expansion of fracking, which has unlocked vast supplies of natural gas from shale deposits nationwide.
Natural gas is used in steam turbines and gas turbines to generate electricity. It is the primary source of electricity generation in 19 states and provides at least 50% of the electricity in nine states. In contrast, coal-powered electric plants generated 30% of the nation's electricity last year, with coal still being the chief source of electricity generation in 13 states.
While renewable energy sources are growing rapidly in the United States, they still lag behind fossil fuels in terms of overall energy production. In 2023, renewable energy sources, including wind, solar, biomass, and geothermal, accounted for about 21% of total U.S. utility-scale electricity generation. Nuclear energy, the third-highest source, contributed about 18% to 19% of U.S. electricity generation.

US fossil fuel consumption is 77.2 quadrillion British thermal units
Fossil fuels have long been the primary energy source in the United States, and in 2023, US fossil fuel consumption was 77.2 quadrillion British thermal units (Btu). This figure represents a decrease of 1.7% compared to 2022. The US consumed 81.28 quadrillion Btu of fossil fuels in 2018, the highest amount since data collection began in 1949.
Fossil fuels are formed from the carbon-rich remains of plants and animals that decomposed and were compressed and heated underground over millions of years. The three major fossil fuels are coal, oil, and natural gas, which are sources of primary energy. In 2023, fossil fuels accounted for 60% of US power production, with natural gas and coal being the most prevalent. Natural gas has been the top fossil fuel since 2016, and its use is projected to increase further.
The US has been reducing its dependence on imported fossil fuels, with net imports accounting for less than 4% of the total energy supply in 2018, compared to 26% a decade earlier. This reduction is due to increased domestic production, driven by new technologies such as fracking and horizontal drilling. Despite the growth of renewable energy sources, fossil fuels still dominate the US energy landscape, meeting nearly all the country's energy needs.
The use of fossil fuels has severe environmental consequences, as burning them releases carbon dioxide and other greenhouse gases, contributing to global warming and climate change. The vast majority of carbon emissions in the US come from fossil fuels, with petroleum, natural gas, and coal being the largest sources of carbon pollution. In 2020, oil was the largest source of US energy-related carbon emissions, followed by natural gas.

Fossil fuels are the main energy source for the transportation sector
Fossil fuels are the dominant energy source for the transportation sector in the United States. Gasoline, including motor gasoline and aviation gasoline, is the primary transportation fuel, accounting for 52% of the sector's total energy consumption in 2022. Distillate fuels, mainly diesel, come second at 23%, followed by jet fuel at 12%. Overall, petroleum products, including gasoline and diesel, accounted for about 89% of the transportation sector's primary energy consumption in 2023. This heavy reliance on fossil fuels results in the transportation sector being the largest source of direct greenhouse gas emissions in the country.
While renewable energy sources are growing in the US, fossil fuels still dominate the energy landscape. In 2018, fossil fuels met about 80% of the nation's energy demand, a slight decrease from 84% a decade earlier. Crude oil and natural gas production have increased dramatically due to new technologies like fracking and horizontal drilling. As a result, the US has become almost entirely self-sufficient in meeting its energy needs, with net imports accounting for less than 4% of its energy supply in 2018.
The transportation sector's dependence on fossil fuels is evident in the breakdown of its energy sources. Petroleum-based fuels, including gasoline and diesel, make up over 94% of the sector's fuel usage. This is a direct contributor to greenhouse gas emissions, with the transportation sector leading as the largest emitter.
To reduce the environmental impact, there is a growing focus on alternative fuels and modes of transportation. Biofuels, for instance, contributed about 6% of the transportation sector's energy consumption in 2022, with most of it blended with petroleum fuels. Additionally, the use of electric vehicles (EVs) is gaining traction, and even with electricity generation relying on fossil fuels, EVs result in lower carbon emissions. Policy incentives, such as subsidies for EV manufacturing and sales and the development of urban infrastructure to promote walking and biking, are also being explored to reduce the transportation sector's reliance on fossil fuels.
