Residential energy consumption statistics: U.S. household site energy use
The latest detailed household consumption tables cited here measure 2020, not current-year use. The U.S. Energy Information Administration (EIA) estimated that primary occupied homes in the 50 states and the District of Columbia used 9,481 trillion British thermal units (Btu) of site energy that year. The estimate represented 123.53 million housing units. Site energy refers to energy used at the home; it is the basis for the household totals and intensities reported in these tables.

Several measures describe that national total from different angles. Average annual site use was 76.8 million Btu per household, while the average per household member was 31.3 million Btu. The table also reports an average of 42.2 thousand Btu per square foot. These figures have different denominators: a home, the people living in it, and its floor area. They should not be treated as interchangeable measures of energy efficiency or as individual household predictions. Source: EIA, Table CE1.1, 2020
| U.S. primary occupied homes, 2020 | Measure |
|---|---|
| Total site energy consumption | 9,481 trillion Btu |
| Housing units represented | 123.53 million |
| Average per household | 76.8 million Btu |
| Average per household member | 31.3 million Btu |
| Average per square foot | 42.2 thousand Btu |
These estimates exclude vacant homes, seasonal units, second homes, and group quarters. The tables also exclude consumption and expenditures for biomass such as wood, coal, district steam, and solar thermal. Electricity generated by on-site solar photovoltaic systems is included. The scope matters when comparing these values with broader energy-sector totals or studies that include excluded fuels and housing types. Source: EIA, Table CE1.1, 2020
The 2024 Residential Energy Consumption Survey (RECS) page says its Consumption & Expenditures tables are scheduled for release in spring 2027. As of the page referenced here, these 2020 tables remain the detailed national household estimates available for the comparisons below. The year is part of the finding: none of the values in this article should be read as a measurement for 2026 or 2024. Source: EIA, 2024 RECS Consumption & Expenditures tables page
Residential energy consumption statistics: space heating, cooling, and other end uses
Space heating was the largest of the separately named end-use totals listed here, at 4,026 trillion Btu in 2020. Water heating accounted for 1,737 trillion Btu, and air conditioning for 866 trillion Btu. Those national totals describe energy attributed to each use across primary occupied homes, not an average per appliance or per household. Source: EIA, Table CE3.1, 2020
Refrigerators accounted for 352 trillion Btu. The “Other” category totaled 2,501 trillion Btu and includes end uses that CE3.1 does not show separately. It is therefore a grouped category rather than one appliance or activity. Keeping that definition in view helps explain why it is a substantial line in the table without implying a single source of demand. Source: EIA, Table CE3.1, 2020
| End use | Total site consumption in 2020 |
|---|---|
| Space heating | 4,026 trillion Btu |
| Water heating | 1,737 trillion Btu |
| Air conditioning | 866 trillion Btu |
| Refrigerators | 352 trillion Btu |
| Other end uses | 2,501 trillion Btu |
These categories provide a useful view of the range of household services captured by residential energy estimates. Heating and cooling are distinct categories, as are water heating and refrigeration. “Other” collects energy uses not displayed individually in this table. The values are aggregate site consumption, so they do not indicate how many homes used a given system or how much any particular home consumed. Source: EIA, Table CE3.1, 2020
Residential energy consumption statistics by fuel
Electricity accounted for 4,453 trillion Btu of household site consumption in 2020, and natural gas accounted for 4,241 trillion Btu. The other two reported fuel totals in the checked comparison were 396 trillion Btu for fuel oil or kerosene and 391 trillion Btu for propane. These are total site consumption values attributed to each fuel across U.S. primary occupied homes. Source: EIA, Table CE4.1, 2020
| Fuel | Total site consumption in 2020 |
|---|---|
| Electricity | 4,453 trillion Btu |
| Natural gas | 4,241 trillion Btu |
| Fuel oil or kerosene | 396 trillion Btu |
| Propane | 391 trillion Btu |
The fuel table also connects fuels to end uses. Electricity used for air conditioning totaled 866 trillion Btu, while natural gas used for space heating totaled 2,887 trillion Btu. Natural gas water heating added 1,081 trillion Btu. These entries show how a fuel can be reported both as an overall total and as consumption assigned to a particular use. Source: EIA, Table CE4.1, 2020
The matching air-conditioning value in the end-use table is 866 trillion Btu, and the fuel table identifies 866 trillion Btu of electricity for that purpose. This is a consistent category-level description in the checked tables; it does not mean all household electricity was used for cooling. Similarly, the natural-gas values for space heating and water heating are specific end-use amounts within the natural-gas total. Sources: EIA, Table CE3.1 and Table CE4.1, 2020
Residential energy consumption statistics across regions and climate zones
Regional totals and per-household averages answer different questions. The Midwest recorded 2,619 trillion Btu of site consumption in 2020, and the South recorded 3,116 trillion Btu. The West total was 1,790 trillion Btu. These are regional aggregates, so they reflect the total consumption attributed to homes in each region rather than the typical individual home. Source: EIA, Table CE1.1, 2020
In per-household terms, Midwest homes averaged 96.9 million Btu of annual site consumption. The Pacific Census division average was 57.4 million Btu per household. The first is a Census region and the second is a division within a region, so the figures are not a like-for-like pair of regional totals. They do, however, illustrate why it is useful to check the table’s geographic category and denominator before comparing values. Source: EIA, Table CE1.1, 2020
The climate-region breakdown uses a separate classification. Homes in the combined Very cold/Cold region used 4,044 trillion Btu of site energy in 2020. In the Hot-humid region, electricity used for air conditioning totaled 299 trillion Btu. One value is total site energy for a combined climate category; the other is electricity for a particular end use in another category. They describe different dimensions and should not be compared as equivalent regional consumption totals. Sources: EIA, Table CE1.1 and Table CE4.1, 2020
Residential energy consumption statistics by home size and housing type
Average use per household differed across the selected floor-area categories. Homes under 1,000 square feet averaged 42.1 million Btu of annual site energy in 2020. Homes from 1,000 to 1,499 square feet averaged 61.7 million Btu. In the larger categories, homes from 2,500 to 2,999 square feet averaged 104.0 million Btu, and homes of 3,000 square feet or more averaged 127.4 million Btu per household. Source: EIA, Table CE1.1, 2020
| Home floor area | Average annual site use per household |
|---|---|
| Less than 1,000 square feet | 42.1 million Btu |
| 1,000 to 1,499 square feet | 61.7 million Btu |
| 2,500 to 2,999 square feet | 104.0 million Btu |
| 3,000 square feet or more | 127.4 million Btu |
The table gives averages for the listed bands, not a continuous estimate for every home size. The values are total household site energy, not energy per square foot. The national per-square-foot measure reported earlier uses a different denominator and should not be inferred from this subset of household averages. Source: EIA, Table CE1.1, 2020
Housing type adds another view. Detached single-family homes accounted for 7,293 trillion Btu of site energy in 2020. Apartments in buildings with 5 or more units accounted for 769 trillion Btu, while mobile homes accounted for 419 trillion Btu. These are totals by housing category, not per-home averages; the categories also represent different numbers of housing units. Source: EIA, Table CE1.1, 2020
For apartments in buildings with 2 to 4 units, the average was 53.5 million Btu per household. That average is a different measure from the aggregate totals above. Comparing it directly with the detached-home total would mix an average with a sum, so the distinction between household intensity and category-wide consumption is essential to reading housing-type statistics. Source: EIA, Table CE1.1, 2020
Residential energy consumption statistics by household size and income
Household size figures also include both averages and aggregate totals. One-member households averaged 54.9 million Btu of site energy per household in 2020. Households with 6 or more members averaged 102.2 million Btu per household. These figures describe average annual use for each household-size group; they are not per-member amounts. Source: EIA, Table CE3.1, 2020
Two-member households, taken together, used 3,554 trillion Btu of total site energy. That aggregate cannot be read as the average for a two-person home. It answers a population-level question, while the one-member and 6-or-more-member figures above are average consumption per household. Source: EIA, Table CE3.1, 2020
Income categories show the same need to distinguish measures. Households with 2020 annual income below $5,000 averaged 56.5 million Btu of site energy per household. For households with income of $150,000 or more, the average was 109.8 million Btu per household, and the group’s aggregate total was 1,852 trillion Btu. The income period is 2020, and the aggregate and average describe different aspects of the high-income category. Source: EIA, Table CE3.1, 2020
Taken together, the tables show how residential energy consumption can be described by totals, household averages, member averages, and floor-area intensity. They also sort use by end use, fuel, geography, building form, household size, and income. Those classifications help explain what a statistic measures, while the 2020 survey scope and exclusions set the boundaries for comparisons.
