U.S. households consumed an average of 76.7 million British thermal units (MMBtu) of site energy in 2020, according to our 2020 Residential Energy Consumption Survey (RECS) data. The average site energy a household uses is largely correlated with the average outdoor temperature; households in colder climates, where space heating equipment is used more intensely, tend to consume more site energy than households in warmer parts of the county. Of the 15 states with average annual temperatures above the national average (59.4°F), the average households in every state except Oklahoma used less energy than the national average.
