June Energy Figures: LEDs could reduce lighting energy use nearly 50% by 2030

The Energy Information Administration estimates total U.S. site electricity consumption at more than 3,500 terawatt-hours (TWh), or 40 quadrillion Btu (quads) of energy in 2010. DOE’s forecast analysis estimates that lighting technologies are responsible for 18% of this electricity use. In residential and commercial buildings, lighting is the second largest end-use of energy, representing approximately 16% of residential and 20% of commercial building electricity. A new report, called Energy Savings Potential of Solid-State Lighting in General Illumination Applications, finds that LED lighting could reduce energy consumption by nearly 20% in 2020 and nearly 50% in 2030. The report also highlights the energy savings potential of LED white-light sources compared to other options, such as incandescent, halogen, and fluorescent lighting. The graph summarizes forecasted annual electricity consumption of lighting technologies and the electricity savings resulting from increased LED use, broken down by building sector.
