What lighting costs to run, by state

Every light fixture and lamp in and immediately outside the home.

Figures cover all homes. Each is the difference lighting makes to a year’s bill on the cheapest and dearest published plan in that state, not a rate multiplied by a wattage.

Pilot data. 450 tariffs from 45 utilities, retrieved September 2, 2026. This is a sample, not national coverage — a utility missing here is one that has not been indexed yet.
