LED lighting will save 5.1 quads by 2035: DoE study

26/09/2016

By BizLED Bureau

The US Department of Energy (DoE) has just published the latest edition of its biannual report titled, ‘Energy Savings Forecast of Solid-State Lighting in General Illumination Applications.’The DoE report extends the projections on energy savings due to LED use in general illumination through 2035, whereas the prior report covered the period through 2030.

This new report models the adoption of LEDs in the US general-lighting market, along with associated energy savings, based on the full potential DOE has determined to be technically feasible over time. The new report uses an updated 2016 US lighting-market model and extends the forecast period to 2035 from the 2030 limit that was used in previous editions.

Major findings of the new DOE report

Annual savings from LED lighting will be 5.1 quads in 2035, nearly equivalent to the total annual energy consumed by 45 million US homes today, and representing a 75% reduction in energy consumption versus a no-LED scenario.

By 2035, LED lamps and luminaires are anticipated to hold the majority of lighting installations for each of the niches examined, comprising 86% of installed stock across all categories compared to only 6% in 2015.


Most of the 5.1 quads of projected energy savings by 2035 will be attributable to two commercial lighting applications (linear and low/high-bay), one residential application (A-type), and one that crosses ­both residential and commercial (directional).


Connected lighting and other control technologies will be essential in achieving these savings, accounting for almost 2.3 quads of the total. From 2015 to 2035, a total cumulative energy savings of 62 quads – equivalent to nearly $630 billion in avoided energy costs – is possible if the DOE SSL program goals for LED efficacy and connected lighting are achieved.
