How much energy does a person use in a year?

In 2020, total U.S. primary energy consumption per person (or per capita consumption) was about 282 million British thermal units (Btu), which the lowest amount since 1965. The drop in annual per capita consumption of 23 million Btu between 2020 and 2019 was mainly because of the record drop in total U.S. energy consumption in 2020.

At the state level in 2019, Wyoming had the highest per capita total primary energy consumption at about 932 million Btu per person, mainly because it had the second-highest per capita industrial sector energy consumption of any state. Rhode Island had the lowest per capita total primary energy consumption at about 180 million Btu per person. In the residential sector, North Dakota had the highest per capita residential energy consumption in 2019 at about 103 million Btu, and Hawaii had the lowest per capita residential energy consumption at about 24 million Btu per person. The U.S. average residential energy consumption per capita in 2019 was about 64 million Btu.

The world average per capita consumption of primary energy in 2018 was about 79 million Btu.
