Understanding Electricity Costs
The formula: Watts ÷ 1,000 × hours × rate = cost. A 1,500-watt space heater running 8 hours at $0.16/kWh costs $1.92 per day, $57.60 per month, and $691 per year. The biggest household electricity users: HVAC (40-50%), water heater (14%), washer/dryer (13%), and lighting (12%). Switching to LED bulbs saves $100-200/year for most homes.
