Understanding Your Electricity Bill

Electricity is measured in kilowatt-hours (kWh). One kWh equals 1,000 watts used for one hour. The average U.S. household uses about 900 kWh per month, costing approximately $120-$150. Your rate varies by region — the national average is about $0.16/kWh, but ranges from $0.10 in some states to over $0.35 in others.

Biggest Energy Consumers at Home

The largest electricity consumers in a typical home are: HVAC (heating/cooling) at 40-50% of the bill, water heater at 12-15%, washer/dryer at 10-13%, lighting at 10-12%, and refrigerator at 5-8%. Switching to energy-efficient appliances and LED bulbs can reduce your bill by 20-30%.

Energy-Saving Tips

Simple changes can significantly reduce your electricity costs: switch to LED bulbs (use 75% less energy), use a programmable thermostat (save 10-15% on heating/cooling), unplug standby electronics (phantom loads cost the average home $100/year), wash clothes in cold water, and air-dry dishes instead of using the heated dry cycle.

Understanding Energy Ratings

The Energy Star label indicates appliances that meet strict energy efficiency standards. An Energy Star refrigerator uses 9-10% less energy than the federal minimum. Energy Guide labels show estimated yearly operating costs, making it easy to compare appliances. Consider lifetime energy costs, not just purchase price, when buying appliances.
