Coffee makers are widely used in U.S. homes, offices, campuses and public buildings, but the available evidence measures different things: household use, ownership, electricity demand, equipment power, or laboratory brew outcomes. The figures below keep those definitions, periods and geographic scopes separate.
Key Coffee Maker Statistics
These are the most broadly useful figures across household adoption, brewing methods, energy use and measured brewing outcomes:
- In 2020, 75% of U.S. households used an electric coffee maker at least occasionally.
- In 2020, 56% of U.S. households used an electric coffee maker daily.
- In Spring 2024, 67% of American adults drank coffee in the past day.
- In Spring 2024, 37% of American adults used drip coffee makers for at-home preparation.
- In Spring 2024, 28% of American adults used single-cup brewers for at-home preparation.
- In Spring 2025, classic drip coffee-maker ownership was 62% among surveyed U.S. respondents.
- In Spring 2025, single-cup brewer ownership was 42% among surveyed U.S. respondents.

Coffee Maker Statistics: Household Use and Ownership
The 2020 Residential Energy Consumption Survey measure reported by the U.S. Energy Information Administration concerns use, not ownership. In that survey, 75% of U.S. households used an electric coffee maker at least occasionally, while 56% used one daily; both figures are self-reported household-use measures for 2020. U.S. Energy Information Administration
Geography matters. Fewer than half of Utah households used an electric coffee maker in 2020, but the source did not state the exact Utah percentage, so it should not be treated as a precise state estimate.
Coffee drinking is a broader measure than coffee-maker use. The National Coffee Association reported that 67% of American adults drank coffee in the past day in Spring 2024, compared with 49% in 2004, and 75% drank coffee in the past week in Spring 2024; these are adult consumption results, not ownership rates. National Coffee Association
Coffee Maker Statistics by Brewing Method and Consumer Behavior
At-home preparation shares help show which methods consumers report using, but they are not necessarily exclusive ownership categories. In Spring 2024, drip coffee makers were the at-home preparation method for 37% of American adults, while single-cup brewers accounted for 28% in the NCA measure. National Coffee Association
The NCA’s Spring 2025 update reported ownership among surveyed respondents rather than all U.S. households. Classic drip coffee-maker ownership was 62%, and single-cup brewer ownership was 42%; the update also reported classic drip ownership 7 percentage points higher than in 2020.
Categories can overlap, and survey populations and wording should be checked before causal interpretation. National Coffee Association
Coffee Maker Energy Use in Homes and Commercial Settings
Older commercial estimates provide scale, but they are not current measured national averages. A U.S. Department of Energy model estimated 3,000,000 installed commercial coffee makers in 2005 and 3,102,000 in 2008, with site energy use of 2.7 TWh per year in 2005 and 2.8 TWh per year in 2008; the 2008 installed-base value was interpolated from a TIAX projection. U.S. Department of Energy
The DOE source table, using 2002 commercial-style market data credited to ADL, divided the market into decanter brewers at 45%, thermal brewers at 30% and satellite brewers at 25%. These shares describe the commercial category only and should not be generalized to household machines. U.S. Department of Energy
A Stanford campus study observed 1,022 coffee makers: 483 single-cup, 421 single-pot and 109 multi-pot units. The rounded category counts do not sum exactly to the stated total because one unit was not categorized in the article’s presentation; estimated annual electricity use was 119,137 kWh for multi-pot makers and 51,895 kWh for single-cup makers. Quantity and electricity consumption of plug load equipment on a university campus
The Stanford study also placed coffee makers within a broader context: they represented 5% of estimated plug-load electricity consumption in the campus kitchen-and-breakroom equipment category. That is not a coffee-maker-only share of all campus electricity.
The PNNL Army-building study inventoried 21 coffee makers and monitored 7. The monitored commercial units averaged 570 kWh per year, compared with 40 kWh per year for monitored non-commercial units; the seven monitored machines used 1,350 kWh per year in total. Pacific Northwest National Laboratory
| Setting or equipment group | Measured or estimated electricity | Period or scope |
|---|---|---|
| DOE commercial model | 905 kWh per unit per year | 2005 and 2008 estimate, United States |
| Stanford multi-pot makers | 119,137 kWh per year | Campus study estimate |
| Stanford single-cup makers | 51,895 kWh per year | Campus study estimate |
| PNNL commercial units | 570 kWh per unit per year | Average of two monitored units |
| PNNL non-commercial units | 40 kWh per unit per year | Average of five monitored units |
The highest-using commercial coffee maker in the PNNL study exceeded 700 kWh per year, while the highest-using residential coffee maker used 80 kWh per year. The latter served an office area and was not presented as a typical household estimate.
Coffee Maker Power Ratings, Standby Use and Efficiency Potential
Input power describes the rating while operating, not annual electricity consumption. In ENERGY STAR’s 2011 market scan, automatic drip makers with 4/5-cup capacity were rated at 550–900 W, full-size 10/12-cup drip makers at 750–1,200 W, capsule single-serve makers at 900–1,500 W, pump and fully automatic espresso machines at 1,000–1,500 W, and steam espresso machines at 600–800 W. ENERGY STAR Market & Industry Scoping Report: Coffee Makers
ENERGY STAR’s 2011 technical estimates for annual household use were 100–150 kWh for a full-size drip filter maker, 45–65 kWh for a single-serve maker, 30–50 kWh for pump or fully automatic espresso machines, and 10–30 kWh for steam espresso machines. The report noted that comparable U.S. measurement procedures were not widely adopted, so these are usage-pattern estimates rather than a measured fleet average.
| Machine category | Estimated annual household use | ENERGY STAR estimate period |
|---|---|---|
| Full-size drip filter | 100–150 kWh | 2011 technical estimate |
| Single-serve | 45–65 kWh | 2011 technical estimate |
| Pump or fully automatic espresso | 30–50 kWh | 2011 technical estimate |
| Steam espresso | 10–30 kWh | 2011 technical estimate |
The same report estimated efficient-machine unit savings of about 7 kWh per year at the low end, associated with espresso machines, and about 25 kWh per year at the high end, associated with drip filter makers. It estimated auto-power-down after 60 minutes could save 14% for drip filter makers, while a 30-minute setting could save nearly 23%; standby-power modifications were estimated to save 3% to 5% overall.
For single-serve and pod models, ENERGY STAR estimated nearly 50% efficiency potential compared with its base case, and more than 30% potential savings for espresso machines using flow-through water heaters. These are technology-scenario estimates, not guaranteed savings for every product.
Coffee Brewing Statistics: Extraction, Caffeine and Chemical Outcomes
Controlled brewing trials describe tested recipes and equipment, not population behavior. One peer-reviewed comparison evaluated eight extraction methods: three espresso systems, cold brew, V60, AeroPress, French Press and Moka. What kind of coffee do you drink?
In that study, beverage volume ranged from 30 mL for espresso to 120 mL for filtered coffee. Moka and filtered coffees were 3 to 6 times less concentrated than espresso coffees, with the comparison dependent on the study’s recipes and definition of concentration. What kind of coffee do you drink?
A separate Pure Brew laboratory study reported the following concentrations for controlled brews:
| Pure Brew result | Medium roast | Dark roast |
|---|---|---|
| Caffeine | 598.28 ± 8.84 µg/mL | 556.13 ± 1.22 µg/mL |
| Total bioactive compounds | 1,726.8 ± 22.4 µg/mL | 1,407.89 ± 9.53 µg/mL |
Pure Brew fell within the study’s 18%–22% ideal extraction range at all three tested roast degrees. The figures are study-specific laboratory outcomes, not averages for retail coffee makers or all consumer cups.

Coffee Maker Electricity Savings and Operating Trends
The PNNL study illustrates how operating schedules can affect commercial loads. Switching off one commercial unit on weekends was associated with about 280 kWh of annual savings, or 40%; this was a before-after comparison of one unit rather than a randomized fleet intervention. Pacific Northwest National Laboratory
A scenario that turned off two commercial coffee makers for 12 hours on weekdays and for all weekends was estimated to save 490 kWh per year, or 43% of current use. The estimate was based on observed profiles, not a controlled intervention across many buildings.
PNNL projected that timer or similar controls could save 2.6 million kWh per year across U.S. Army administrative buildings. This was an extrapolation from 34.3 kWh per 1,000 square feet, not a measured Army-wide result.
Standby measurements also varied by equipment type. PNNL measured approximately 1.3 W for two single-serve units and observed about 50 W for commercial Bunn units in the comparison profile; these observations apply to the study units, not universal specifications. Pacific Northwest National Laboratory
A broader ENERGY STAR retail-sales-based estimate found that replacing 25% of products sold with efficient models could save 124,000 MWh per year nationally, based on 2010 sales data. The same scenario estimated a reduction of about 190 million pounds of annual CO2 using the report’s assumed conversion factor of 1.54 lb CO2 per kWh; the estimate excluded possible hospitality and office undercounting.
