Understanding Electricity Costs

Electricity is measured in kilowatt-hours (kWh). One kWh equals 1,000 watts used for one hour. The average US electricity rate is about $0.12/kWh, but it varies by state from $0.08 to $0.30+. The biggest energy consumers in most homes are HVAC systems, water heaters, and dryers. Switching to energy-efficient appliances and LED lighting can significantly reduce your electricity bills.
