Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: April 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility.
