How much energy does a person use in a year?

In 2015, total U.S. primary energy consumption per person (or per capita consumption) was about 303 million British thermal units (Btu). Louisiana had the highest per capita primary energy consumption in 2015 at about 912 million Btu per person, mainly because it has the highest per capita industrial sector energy consumption of any state.

The world per capita consumption of primary energy in 2011 was about 75 million Btu. (2011 is the most recent year for which EIA has published population estimates.)
