Fossil fuels generated 2,509 TWh of electricity in 2023
In 2023, the US energy landscape was largely defined by fossil fuels, with 38% of the nation's energy originating from petroleum, 36% from natural gas, and 9% from coal. These three fossil fuels combined accounted for 84% of total US primary energy production, with nuclear power and renewable energy sources making up 9% each. The US is the world's second-largest producer and consumer of electricity, generating 15% of the global electricity supply.
The US has a diverse energy portfolio, but fossil fuels remain the major source of energy. In 2023, the country produced 102.8 quads of energy, with net exports of 7.6%. While the use of coal has declined over the years, being replaced by natural gas, fossil fuel usage has remained near 80% for the past 30 years.

Petroleum, natural gas and coal are the primary fossil fuels
Fossil fuels are the primary sources of energy in the United States, with petroleum, natural gas, and coal being the most used fossil fuels. In 2023, fossil fuels generated 2,509 TWh of electricity, accounting for 60% of all electricity generation in the US. Fossil fuels have dominated the US energy mix for over 100 years, although their share of total energy production has been decreasing over time. In 2023, fossil fuels accounted for 84% of total US primary energy production, down from 99% in 1949.
Petroleum, also known as crude oil, is a fossil fuel that is extracted from underground reservoirs or deposits in shale and tar sands. It is a mixture of thousands of different molecules, mostly made up of hydrogen and carbon compounds. Petroleum has a range of densities and can be designated as either sweet or sour depending on its residual sulfur content. It is used in various industries, from transportation to plastics and medicine. In 2023, petroleum accounted for 38% of US energy consumption, a decrease from its peak of 49% in the 1970s.
Natural gas is another important fossil fuel for the US. It is obtained from natural gas fields and has been increasing its share of the US energy mix since the 1990s. In 2020, natural gas provided one-third of US energy consumption and was responsible for 36% of US greenhouse gas emissions. The use of natural gas is projected to increase further due to its low price and lower carbon dioxide emissions compared to other fossil fuels.
Coal is the third major fossil fuel used in the US. It has been used for centuries, dating back to early furnaces for smelting metal ore. Coal use underwent a steady decline in the 2010s, mainly due to being replaced by natural gas, the closing of old plants, and environmental regulations. In 2021, coal accounted for 9% of US energy production, with 90% of it used for electricity generation.
While fossil fuels provide a significant portion of US energy needs, there are concerns about their environmental impact. Fossil fuels are non-renewable resources that contribute to carbon emissions and air pollution, leading to efforts to transition to renewable energy sources.

Fossil fuels accounted for 84% of total US energy production in 2023
Fossil fuels—petroleum, natural gas, and coal—accounted for about 84% of total US primary energy production in 2023. The United States is the world's second-largest producer and consumer of electricity, generating 15% of the world's electricity supply. In 2023, the US produced 102.8 quads of energy, with net exports of 7.6% of production.
The breakdown of US energy consumption in 2023 was as follows: 38% petroleum, 36% natural gas, 9% coal, 9% nuclear power, and 9% renewable energy. Fossil fuels have long been the dominant source of energy in the US, and while the mix has changed over time, it has remained near 80% for the past 30 years. The vast majority of carbon emissions in the US come from fossil fuels, with petroleum, natural gas, and coal as the largest sources of carbon pollution.
While renewable energy sources have been growing rapidly in the US, they still only account for a small portion of the country's energy production. In 2018, solar and wind power accounted for under 4% of all energy used in the US. However, renewables are becoming cheaper, and natural gas has been replacing coal, leading to a decline in emissions from these sources since 2008.
The US has a diverse portfolio of energy sources, with petroleum, natural gas, and coal as the primary fossil fuels. In 2023, petroleum consumption in the US was at its highest level since data collection began in 1949. Natural gas production has tripled from 2000 to 2022, and the US leads the world in NGL production. While coal consumption has declined, it still plays a significant role in US energy production, especially in electricity generation.

Natural gas liquids production tripled from 2000 to 2022
The United States is the world's second-largest producer and consumer of energy, generating 15% of the world's electricity supply. In 2023, the US produced 102.8 quads of energy, with fossil fuels accounting for 84% of total production and 60% of electric generation. Fossil fuels—petroleum, natural gas, and coal—have dominated the US energy mix for over a century.
Natural gas liquids (NGLs) are liquid hydrocarbons obtained from natural gas fields. NGL production tripled from 2000 to 2022 and now constitutes 9% of fossil fuels. The US leads the world in NGL production, surpassing Saudi Arabia. The increase in NGL production can be attributed to several factors, including the declining price of coal and the rising cost of crude oil after the 2008 Recession, which made natural gas a more attractive alternative. Additionally, low-interest rates during this period led to new investments in techniques like horizontal drilling and hydraulic fracturing (fracking) to extract natural gas. Shale gas, often obtained through fracking, has become a prevalent form of natural gas, with shale gas production in the US surging since the financial crisis.
The US energy landscape is dynamic, with natural gas gradually replacing coal. As a result, emissions from coal and natural gas combined have decreased by 25% since their peak in 2008. While fossil fuels remain dominant, renewable energy sources are becoming increasingly competitive. In 2023, renewable energy supplied 9% of the US energy mix, including biomass, wind, hydro, solar, and geothermal sources. The US has witnessed a rapid expansion of solar and wind power usage in the past decade, indicating a shift towards cleaner energy alternatives.
The US energy sector is also influenced by factors such as energy efficiency and consumption patterns. Per capita energy use in the US has generally declined since the turn of the 21st century, with improvements in building insulation and fuel efficiency contributing to reduced energy consumption in urban areas. However, there is still significant room for enhancing energy efficiency, as approximately two-thirds of all energy used in the US in 2018 was wasted.
In conclusion, the US energy profile is characterised by a historical reliance on fossil fuels, with natural gas liquids production tripling between 2000 and 2022. However, the country is also witnessing a growth in renewable energy sources and efforts to improve energy efficiency, shaping the future of its energy landscape.
