Petroleum, Natural Gas, and Coal Still Dominate U.S. Consumption

Fossil fuels—petroleum, natural gas, and coal—have accounted for at least 80% of energy consumption in the U.S. for well over a century, notes the Energy Information Administration (EIA). However, the fossil fuel share of total energy consumption in 2017 was the lowest since 1902, at a little more than 80% as consumption decreased for the third consecutive year.

EIA comments that the decline in fossil fuel consumption last year was driven by slight decreases in coal and natural gas consumption. Coal consumption fell by 2.5% in 2017, following larger annual declines of 13.6% and 8.5% in 2015 and 2016, respectively. U.S. consumption of coal peaked in 2005 and has fallen nearly 40% since then.

Natural gas consumption fell by 1.4% in 2017, a change from recent trends. Unlike coal consumption, which has decreased in eight of the past 10 years, natural gas consumption has risen in eight of the past 10 years, and was twice that of coal last year. Natural gas consumption growth has been driven by increased use in the electric power sector. Overall, U.S. consumption rose 24% from 2005 to 2017.

Petroleum consumption increased in 2017, but remains 10% lower than its peak level, also set in 2005. Mainly used in the transportation sector, several petroleum-based fuels are also used in homes, businesses, and industries. Petroleum has been the largest source of energy consumption in the U.S. since surpassing coal in
1950.

The renewable share of energy consumption in 2017, which includes hydroelectricity, biomass, and other renewables such as wind and solar, was 11.3%, the highest since 1910 when overall energy consumption was lower and biomass consumption, mainly wood, made up a larger share. The largest growth in renewables over the past decade has been in solar and wind electricity generation.

Energy consumption in the U.S. has undergone many changes over the course of the nation’s history, EIA observes, from wood as the primary resource in the 18th and 19th centuries, to the onset of coal and petroleum use, to the more modern rise of nuclear power in the late 20th century, and to renewables in the early 21st century.
