Methodology
Energy cost rankings use EIA residential electricity rate data by utility service area, mapped to ZIP codes. Rates are in cents per kilowatt-hour (c/kWh). The national average is approximately 16-17 c/kWh. High energy costs combined with older housing stock indicate significant homeowner burden.
Data sources: EPA Safe Drinking Water Information System (SDWIS), FEMA National Flood Insurance Program, EPA radon zone maps, EIA electricity rates, and Consumer Confidence Reports. Last updated: 2026-10-18.
Frequently Asked Questions
Why are energy costs included in home safety?
Energy burden is a key factor in home affordability and livability. ZIP codes with high electricity rates and older housing stock face compounding costs: higher bills, more expensive repairs, and greater risk of deferred maintenance that leads to safety hazards.
How can homeowners reduce energy costs?
Federal and state rebates are available for insulation, heat pumps, weatherization, and solar panels. The Inflation Reduction Act provides up to $14,000 in home energy rebates. Check energystar.gov/rebates for eligibility.
