10 Surprising U.S. Electricity Cost Stats (2026)

Computed from the latest U.S. EIA Electric Power Monthly (April 2026), real-world appliance wattages, and EPA-rated EV efficiencies. Numbers update monthly with each new EIA release.

  1. U.S. residential electricity rates vary 4×. At 12.35¢/kWh, North Dakota is the cheapest — Hawaii pays 46.62¢/kWh, or 3.8× more. See the full ranking →
