Washington, DC--The U.S. Department of Energy (DOE) has released a report analyzing markets where light-emitting diodes (LEDs) compete with traditional lighting sources (for example, incandescent and fluorescent). The report, "Adoption of Light-Emitting Diodes in Common Lighting Applications," provides estimates of current energy savings, as well as potential savings if these markets switched to LEDs overnight.
Nine markets were analyzed:
--Four indoor lamp applications (A-type, directional, MR-16, and decorative)
--Three indoor luminaire applications (downlight, troffer, and high-bay)
--Two outdoor luminaire applications (streetlight and parking lot/garage).
In addition, if these nine markets switched to LEDs overnight, annual source energy savings could approach 3,873 tBtu, or about 3.9 quadrillion Btu (quads), saving nearly $37 billion in annual energy costs. This amount represents approximately half of the total national lighting energy consumption in 2012.

The report notes that "the energy consumption and savings estimate results are highly sensitive to the state of LED
technology"; accordingly, it considered the best available existing LED technologies (see table below), rather than trying to do any projections based on upcoming but not yet available technologies.
