The U.S. Energy Information Administration (EIA) estimates that in 2019, the U.S. residential and commercial sectors combined used about 216 billion kilowatthours (kWh) of electricity for lighting. This was about 8% of total electricity consumption by both of these sectors and about 5% of total U.S. electricity consumption.
Residential sector electricity consumption for lighting was about 75 billion kWh or about 5% of total residential sector electricity consumption in 2019.
The commercial sector, which includes commercial and institutional buildings, and public street and highway lighting, consumed about 141 billion kWh for lighting in 2019, equal to about 10% of total commercial sector electricity consumption. EIA does not have an estimate of electricity use specifically for public street and highway lighting.
In 2014, about 55 billion kWh were consumed for facility lighting in manufacturing facilities, which was equal to about 1.4% of total U.S. electricity consumption in 2014.1
