Frequently Asked Questions
What uses the most electricity in my home?
Top energy users: 1) Heating/cooling (40-50% of bill), 2) Water heater (15-20%), 3) Refrigerator (5-10%), 4) Washer/dryer (5-10%), 5) Lighting (5-10%), 6) TV/entertainment (3-5%). Percentages vary by climate and usage. Focus efficiency improvements on top 3 categories for maximum savings.
Is it worth replacing old appliances for energy savings?
Replace if: appliance is 10+ years old, uses >50% more energy than Energy Star model, or needs major repair. Example: old refrigerator uses 1,000-1,500 kWh/year ($120-225), new Energy Star uses 300-400 kWh/year ($36-60), saving $84-165/year. At $800 new cost, payback is 5-10 years.
How much do phantom loads really cost?
Standby power (phantom loads) typically costs $100-200/year per household. Major culprits: cable boxes (30W), game consoles (15W), computers (5W), chargers (5W each). Solution: use smart power strips, unplug devices when not in use, or enable device sleep modes. Easy 5-10% electricity bill reduction.
