US home energy cost intelligence

See what you actually pay for electricity — and what changes if you switch.

WattClear turns published US utility tariff data into plain numbers: your effective rate, how it compares, and what you would save by switching plans, shifting usage, or changing equipment.

Homes across the US paid 17.9¢ per kWh over the 12 months to June 2026, 6.7% more than the 12 months before. The average bill came to $156 a month, 5.9% more than the year before, though homes used 0.7% less electricity.

The largest rises among the states: Maryland +18.5%, New Jersey +16.0%, Pennsylvania +12.9% (tied) and Washington +12.9% (tied); Washington, DC, shown unranked, +24.9%. Price or use: why bills went up

ZIP code centres from the US Census Bureau, 2025 Gazetteer Files: ZIP Code Tabulation Areas (Public domain, retrieved October 1, 2026); state outlines from us-atlas 3.0.1 (Census Bureau cartographic boundaries, 2017) (ISC); utilities by ZIP code from NREL, "U.S. Electric Utility Companies and Rates: Look-up by Zip Code (2024)" (CC BY 4.0, retrieved September 23, 2026), aggregated here into the map’s cells; prices from U.S. Energy Information Administration, electricity retail sales (US Government public domain, retrieved September 23, 2026); homes from U.S. Energy Information Administration, Form EIA-861, 2024 (US Government public domain, retrieved September 23, 2026). A ZIP code is drawn in the cell that holds its centre, or in the nearest cell of its own state when the centre falls across a state line, and service territories do not follow ZIP boundaries, so the edges are approximate. DC is smaller than one dot and is not drawn.

Rates in the 50 states and DC

Beside each state, its EIA average over the same 12 months. Each page prices its utilities’ published plans against that figure.
