U.S. Home Electrification Statistics: Household Energy Demand and End Uses

The 2020 Residential Energy Consumption Survey (RECS) estimated average U.S. household site energy use at 76.8 million Btu per household. This modeled measure excludes generation and delivery losses, so it describes energy used at the home rather than the full upstream energy system (Estimating heating and other end uses in the 2020 Residential Energy Consumption Survey).

The survey represented an estimated 123.5 million U.S. homes. Average household energy expenditure intensity was $1.04 per square foot in 2020, although that average masks substantial household and regional variation (2020 RECS Technical Documentation; Estimating heating and other end uses in the 2020 Residential Energy Consumption Survey).

2020 U.S. residential end use Share of annual household energy use
Space heating and air conditioning 52%
Water heating, lighting and refrigeration 25%
Other devices and appliances 23%

These are modeled RECS end-use estimates. The remaining 23% is a residual category after the listed uses, and shares vary with climate, home size and equipment (Use of energy in homes).

Home Electrification Data: Heating Fuels and Heat-Pump Adoption

Heating-fuel data show that electrification was already substantial in 2020, but natural gas remained the leading main heating fuel in U.S. homes. The final RECS estimates include 95% confidence intervals, reflecting survey and modeling uncertainty.

Main heating fuel, 2020 U.S. homes 95% confidence interval
Electricity 42.57 million 41.79-43.35 million
Natural gas 62.71 million 61.75-63.68 million
Fuel oil or kerosene 4.93 million 4.59-5.28 million
Propane 5.21 million 4.82-5.60 million
Wood 2.25 million 2.03-2.47 million
No heating equipment 5.79 million 5.28-6.30 million

Source: 2020 RECS Technical Documentation. These are final modeled estimates for U.S. homes, not a global electrification rate.

Heat pumps were the main heating equipment in 16.13 million U.S. homes in 2020, including 1.06 million homes where ductless heat pumps were the main equipment. Built-in electric heating units served 7.65 million homes, while central warm-air furnaces served 74.42 million (2020 RECS Technical Documentation).

EIA summarized the 2020 result as about 13% of U.S. households using a heat pump as their main heating equipment. The older 2015 RECS analysis counted 12.1 million U.S. heat-pump households; 9.3 million were in hot-humid and mixed-humid climate regions, and the South also contained 9.3 million of the 12.1 million households (Use of energy in homes; 2020 RECS Technical Documentation).

For context, natural gas accounted for 47% of U.S. households’ main heating fuel in 2015, while electricity accounted for 36%. The 2015 figures are from an older RECS cycle and are not directly comparable to every final 2020 equipment estimate.

Cooling is a major electrified household end use. In 2020, air conditioning represented 19% of U.S. residential site electricity consumption, while space heating and water heating each represented 12%; about 89% of U.S. homes used air conditioning (Electricity use in homes).

Indicator Earlier period 2020 U.S. homes
Any air conditioning 57% in 1980 89%
Central air conditioning 27% in 1980 67%
Homes with a refrigerator – 99%
Homes with two or more refrigerators – 34%

Air-conditioning and refrigerator figures are RECS-based estimates or long-run survey comparisons, not measures of the efficiency of individual appliances. In the Midwest, 38% of homes had a second refrigerator and 44% had a separate freezer in 2020 (Electricity use in homes).

Residential electricity prices and consumption moved in different directions between 2022 and 2023. The average price rose from 15.04 to 15.98 cents per kWh, a 6.2% increase, while average monthly consumption fell from 899 to 861 kWh per customer.

The average residential electricity bill was $138 per month in 2023, compared with $135 in 2022. EIA estimates these bills from utility revenue divided by consumption, and the 2023 consumption sample was preliminary (Increases in U.S. residential electricity bills in 2023 were outpaced by inflation).

Annual sales and newly installed capacity measure market flow, not the installed stock of household equipment. That distinction matters when comparing adoption across countries or with the U.S. household estimates above.

Market Period Reported change or share
Global heat-pump sales 2022 +11% year over year
Europe heat-pump sales 2022 Nearly +40%
European air-to-water sales 2022 Almost +50%
Global newly installed capacity 2023 vs. 2022 -3%
European purchases 2023 -6.5% year over year

The 2022 sales measures come from the IEA’s market analysis (Global heat pump sales continue double-digit growth). The 2023 capacity and European purchase figures come from Renewables 2024: Global overview.

National results varied sharply in 2023. Germany’s heat-pump sales rose 59%, the Netherlands’ rose 43% and Belgium’s rose 72%, while Italy’s fell 44%, Finland’s fell 42% and Poland’s fell 39% (Renewables 2024: Global overview).

China manufactured 40% of heat pumps sold globally in 2023. This is a manufacturing-origin estimate, not the destination of sales or the share of homes with installed heat pumps.

Home Electrification Costs, Efficiency and Water-Heating Savings

ENERGY STAR’s 2019 heat-pump water-heater factsheet modeled savings against standard electric resistance water heating for different U.S. household sizes. These are scenario estimates using factsheet assumptions and historical energy prices, not guarantees for every household.

Household size Modeled annual saving Modeled payback Modeled lifetime saving
Two people $170 4.6 years –
Three people $260 3.0 years –
Four people $350 2.3 years $3,750

Source: ENERGY STAR Heat Pump Water Heater Factsheet. Payback depends on equipment price, incentives and utility rates.

A separate ENERGY STAR counterfactual scenario estimated that if all U.S. residential electric heat-pump water heaters sold were ENERGY STAR certified, annual energy-cost savings would reach $11.8 billion. The same scenario estimated more than 140 billion pounds of greenhouse-gas emissions avoided annually, described as equivalent to removing more than 13 million vehicles for one year; the vehicle comparison is an emissions equivalence, not a measured vehicle reduction.

Home Electrification Forecasts: Grid Demand, Buildings and Emissions

DOE’s air-source heat-pump comparison uses standardized operating assumptions rather than typical use for every home. One rated case uses a 36,000-Btu-per-hour unit, 3,285 cooling-mode hours and 642 heating-mode hours per year, while the life-cycle cost method applies a 3% discount rate (Purchasing Energy-Efficient Residential Air-Source Heat Pumps).

Building efficiency and electrification also depend on the construction pipeline. In the IEA’s 2025 assessment, building energy codes applied to around half of new floor area in emerging economies; code coverage does not necessarily equal compliance (Energy Efficiency 2025: Buildings).

The IEA’s 2023 renewable-heat outlook projected that heat pumps would account for one-third of global electricity-use growth for heat during 2023-2028. It also projected that heat pumps would account for nearly one-quarter of growth in renewable electricity use during the same period (Renewables 2024: Global overview).

The outlook’s space-heating scenario showed global heat-pump stock approaching 3,000 GW in 2030, almost triple the capacity at the time of the scenario. This is a forecast scenario, not a current measurement of installed household equipment.
