The U.S. Department of Energy (DOE) has released a report that documents the increased adoption of energy-efficient lighting products in the United States over the last decade. The 2010 U.S. Lighting Market Characterization examines the current conditions and broad trends in the U.S. lighting market, broken down by technology and sector.

The report also details specific products, including comprehensive and detailed estimates of the national inventory of installed lighting products, as well as their performance characteristics, associated energy use, and lumen production – a measure of brightness. The report helps chart progress made toward the goal of transitioning to more energy-efficient lighting technologies across four sectors: residential buildings, commercial buildings, industrial buildings, and outdoor applications.

The study shows that in 2010, lighting used approximately 700 terawatt-hours (TWh), or nearly19% of the electricity produced in the United States. Of the total energy used for lighting, the commercial sector consumed nearly half, or 349 TWh, primarily with fluorescent lighting products. While there are nearly 6 billion light bulbs installed in the residential sector, far more than the approximately 2 billion lamps in the commercial buildings sector, the mostly incandescent residential lamps were not used nearly as much per day, on average, as lights in the commercial sector.
