How much electricity is used for lighting in the United States?
The U.S. Energy Information Administration (EIA) estimates in the Annual Energy Outlook 2021 that in 2020, the U.S. residential and commercial sectors combined used about 219 billion kilowatthours (kWh) of electricity for lighting. This was about 8% of total electricity consumption by both of these sectors and about 6% of total U.S. electricity consumption.
Residential sector electricity consumption for lighting was about 62 billion kWh or about 4% of total residential sector electricity consumption and about 2% of total U.S. electricity consumption in 2020.
The commercial sector, which includes commercial and institutional buildings, and public street and highway lighting, consumed about 157 billion kWh for lighting in 2020, equal to about 12% of total commercial sector electricity consumption and about 4% of total U.S. electricity consumption in 2020. 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
