Major Appliances: Detailed Breakdown
Refrigerator
Runs 24/7 but cycles on/off.
| Refrigerator Type | Estimated Wattage | Daily kWh | Annual Cost* |
|---|---|---|---|
| Older model (pre-2000) | 200-600W | 1.5-4 kWh | $66-$175 |
| Standard (post-2010) | 100-200W | 1-2 kWh | $44-$87 |
| Energy Star certified | 80-150W | 0.8-1.5 kWh | $35-$66 |
| Mini fridge | 50-100W | 0.5-1 kWh | $22-$44 |
| French door (large) | 100-250W | 1-2.5 kWh | $44-$109 |
*$0.12/kWh
Tip: A refrigerator from the 1990s can cost 2-3x more to run than a modern Energy Star model. Replacing an old unit can save $100-$200/year.
Clothes Dryer
| Dryer Type | Wattage | Cost Per Load | Monthly (6 loads/wk) |
|---|---|---|---|
| Electric dryer | 5,000-6,000W | $0.45-$0.54 | $11.88-$14.04 |
| Gas dryer (gas cost) | — | $0.25-$0.35 | $6.50-$9.10 |
| Heat pump dryer | 1,500-2,500W | $0.14-$0.23 | $3.60-$5.94 |
*Electric at $0.12/kWh; assumes 45 min per load
Gas vs electric dryer: Using a gas dryer instead of electric saves about $60-$120/year if you do laundry frequently.
Heat pump dryers cost more upfront ($800-$1,500 vs. $400-$700) but use ~60% less electricity.
Washing Machine
| Wash Setting | Wattage | Cost Per Load |
|---|---|---|
| Cold water | 400-500W | $0.04-$0.05 |
| Warm water | 700-900W | $0.07-$0.09 |
| Hot water | 1,000-2,000W | $0.10-$0.20 |
*Plus water heating cost if using hot water
Washing in cold water saves $50-$100/year vs. hot water and is equally clean for most laundry.
Dishwasher
| Cycle | kWh Per Run | Cost Per Run* | Monthly (1 run/day) |
|---|---|---|---|
| Normal | 1.0-1.5 kWh | $0.12-$0.18 | $3.60-$5.40 |
| Heavy/Pots | 1.5-2.5 kWh | $0.18-$0.30 | $5.40-$9.00 |
| Energy saver | 0.8-1.2 kWh | $0.10-$0.14 | $3.00-$4.20 |
| Air dry setting | 0.7-1.0 kWh | $0.08-$0.12 | $2.40-$3.60 |
*At $0.12/kWh
Electric Range/Oven
| Use | Wattage | Cost |
|---|---|---|
| Oven (350°F, 1 hr) | 2,000-5,000W | $0.24-$0.60 |
| Stovetop burner (medium, 30 min) | 1,000-2,000W | $0.06-$0.12 |
| Microwave (5 min) | 1,000-1,500W | $0.01 |
| Toaster oven (30 min) | 1,200-1,800W | $0.07-$0.11 |
| Air fryer (30 min) | 1,400-1,800W | $0.08-$0.11 |
| Slow cooker (8 hrs) | 200-300W | $0.19-$0.29 |
Microwave vs oven for reheating: Microwave uses ~1/10 the energy of the oven. Use it whenever possible.
Water Heater
| Type | Annual Cost* |
|---|---|
| Electric standard (50 gal) | $400-$600 |
| Gas standard (50 gal) | $180-$300 |
| Heat pump water heater | $150-$250 |
| Tankless electric | $300-$500 |
| Tankless gas | $100-$200 |
*Family of 4, average usage
Biggest opportunity: Heat pump water heaters use 60-75% less electricity than standard electric. Long payback (3-8 years) but significant annual savings.

Frequently Asked Questions
What uses the most electricity in a house?
HVAC (heating and cooling) is #1 in most homes at 40-50% of the electric bill. Water heating is #2 at 14-18%. Washer/dryer is #3. These three typically account for over two-thirds of your electricity use.
How do I find out which appliance is using the most electricity?
A plug-in watt meter (like the Kill-A-Watt, ~$20-$30) measures any appliance’s actual power draw and can calculate daily/monthly cost. For your whole home, a smart meter or smart circuit breaker panel (like Emporia Vue) shows real-time usage by circuit.
Should I unplug appliances when not in use?
For high-standby devices (cable boxes, game consoles, older TVs): yes, or use a smart power strip. For fridges, clocks, and devices with important settings: no. Focus on the biggest standby users—cable box and game consoles together can waste $50-$70/year.
Are new appliances worth the electricity savings?
Depends on the age of your current unit. Replacing a 20-year-old refrigerator with an Energy Star model: $80-$150/year savings, pays back in 3-7 years. Replacing a 5-year-old fridge: unlikely to pay back. Focus on oldest, least-efficient appliances first.

Your electric bill is driven by a handful of big appliances—HVAC, water heater, and laundry—with everything else making up a smaller slice. The highest-ROI changes are also the simplest: adjust your thermostat, switch to LED bulbs, wash clothes in cold water, and eliminate standby power waste. These free and low-cost changes can cut $150-$300/year without any major purchases.
