Fossil fuels account for 80-84% of US energy production
Fossil fuels—including petroleum, natural gas, and coal—accounted for about 80-84% of total US primary energy production in 2018 and 2023. In 2023, the US consumed about 94 quadrillion British thermal units (Btu) of energy, with 83% coming from fossil fuels. This is a slight decrease from 2018, when fossil fuels accounted for 80% of the nation's energy demand, down from 84% a decade earlier.
The United States is one of the largest consumers of energy in the world, second only to China. In 2018, the total amount of energy used in the US hit 101.2 quadrillion Btu, the highest level since data collection began in 1949. Fossil fuels are the dominant source of energy in the US, but renewable energy sources are growing. In 2018, solar and wind power accounted for less than 4% of the country's energy use, with solar providing only 1% and hydropower being the biggest renewable source at 2.8%. However, public concern about climate change is driving a shift towards renewable energy sources, with 77% of Americans saying it is more important to develop alternative energy sources than to produce more fossil fuels.
The US has made some progress in reducing its reliance on fossil fuels and transitioning to a cleaner energy system. Nuclear energy, for example, has increased in recent years and accounted for about 9% of the country's energy consumption in 2023. Additionally, the number of electric vehicles and EV charging stations in the US is growing, and policies and incentives for renewable energy are being implemented at the state and federal levels. However, fossil fuel subsidies remain a roadblock to a clean energy transition, with global fossil fuel subsidies surging to a record $7 trillion in 2022, including $760 billion from the US.
The environmental and health impacts of fossil fuels are significant. Leaks from natural gas plants, wells, and pipelines emit methane, a greenhouse gas that is 25 times more effective than carbon dioxide at trapping heat in the atmosphere. Coal combustion produces a variety of air pollutants, including sulfur dioxide, nitrogen oxides, mercury, and particulate matter, which harm human and environmental health. Oil spills, such as the 2010 BP Deepwater Horizon disaster, also have devastating and long-lasting impacts on ecosystems and human health.
