Sources

Every figure on this site comes from a public dataset published by a U.S. government agency or a state utility commission. Each page lists the sources it cites; this page lists them all, with their period, release date and licence.

How we use them

The U.S. Energy Information Administration is the primary source: its monthly survey for state and utility prices, its annual census of every utility, and its generation, capacity and household-consumption surveys. Census Bureau, Bureau of Labor Statistics, NOAA and HHS data add what households report paying, consumer price changes, weather and bill assistance. State commission data are used for retail-choice details. Federal data are in the public domain; state publications are cited with attribution. EIA asks users to acknowledge it with the publication date, which every source line on this site does.
