Washing machines vary in energy use depending on load size, temperature, and efficiency rating.
Electricity Use Per Load
Typical washing machines use:
-
0.3–2.0 kWh per load
-
Average: 0.5–1.0 kWh per load
Hot water cycles drastically increase total energy use.
Cost Per Load
At $0.20/kWh:
-
Low-energy washer (0.4 kWh): $0.08
-
Older washer (1.5 kWh): $0.30
Factors Affecting Energy Use
-
Water temperature
-
Load size
-
Machine age
-
Spin speed
Ways to Reduce Washing Machine Energy Use
-
Wash with cold water
-
Run full loads
-
Use high-efficiency detergents
-
Choose high spin speed to reduce drying time
Conclusion
Modern washers use far less electricity than older models and can save money with efficient habits.
