Estimate your monthly electricity bill from appliance usage. Find what is driving your bill up.
What Drives Your Electric Bill
HVAC (40-50%): Heating and cooling is almost always the biggest electricity consumer. A central AC running 8 hours/day costs $125-175/month. Water heating (14-18%): Electric tank heaters cost $35-55/month. Lighting (5-10%): LED bulbs cut lighting costs by 75% vs incandescent. Everything else (25-30%): Fridge, washer, dryer, electronics, cooking.
Biggest Savings Opportunities
Smart thermostat: $100-200/year savings (10-15% of HVAC). LED bulbs: $75-150/year (if replacing incandescent). Heat pump water heater: Uses 60-70% less energy than standard electric. Seal air leaks: $50-200/year (weatherstripping, caulking). These four changes save the average household $300-600/year.
The cheapest electricity is the electricity you do not use. Sealing air leaks (weatherstripping doors and caulking windows) costs $20-50 in materials and can reduce HVAC costs by 10-20%. This is the highest-ROI home improvement project possible — $20 investment saving $100-200/year.
