The biggest energy consumers are: water heaters (4,500W), central AC (3,500W), electric dryers (3,000W), electric ovens (2,500W), and space heaters (1,500W). Refrigerators use less power but run 24/7.
How much does it cost to run an appliance?▾
Cost = (Watts x Hours/Day x 365) / 1000 x Rate. A 1,500W space heater running 8 hours/day at $0.13/kWh costs about $570/year. A 150W refrigerator running 24/7 costs about $171/year.
How can I reduce my electricity bill?▾
Replace old appliances with Energy Star models (saves 10-50%), use LED bulbs, set AC to 78°F, use cold water for laundry, unplug phantom loads, and run dishwasher/dryer during off-peak hours.
