- ✓ Switch to LED bulbs. A 60W incandescent replaced by a 9W LED saves ~$15/year per bulb at 3 hours/day. A typical home with 30 bulbs saves $400+ per year. LEDs also last 25x longer.
- ✓ Kill vampire loads. Devices drawing power when "off" (TVs, chargers, game consoles, microwaves) can add 5-10% to your bill. A single $20 smart strip pays for itself in 2-3 months.
- ✓ Use a smart thermostat. Heating and cooling is 40-50% of the average bill. Programming 7-10°F setbacks when asleep or away saves 10-15% — about $150-200/year for most homes.
- ✓ Air-dry clothes. An electric dryer uses 2-3 kWh per load — about $0.40-$0.50 each. Skipping 3 loads/week saves $60-75/year. Use drying racks or a clothesline when weather permits.
- ✓ Upgrade old appliances. A 15-year-old refrigerator uses 400+ kWh/year more than a modern ENERGY STAR model — that's $60-80/year in wasted electricity. Many utilities offer rebates of $50-150 for recycling old fridges.
Disclaimer: This calculator provides electricity cost estimates for planning purposes only. Actual consumption varies with appliance efficiency, ambient temperature, usage patterns, and rate plans (time-of-use, tiered, flat). Always verify the wattage on your appliance's label and the rate on your electric bill for the most accurate estimate. Standby/vampire loads are not included — add 5-10% to account for them.
