LED Traffic Lights Continue to Save Energy Nationwide
A growing number of municipalities are replacing their incandescent traffic lights with new energy-saving lights that use light-emitting diodes (LEDs). Back in January, the New York State Energy Research and Development Agency (NYSERDA) announced that the City of Syracuse had installed LED traffic lights at 299 intersections, saving $225,000 in energy costs each year. In late May, ABM Industries Inc. announced that its subsidiary, Amtech Lighting Services, won contracts to install LED traffic lights at 1,100 intersections in Dallas, Texas, and at 243 intersections in Arlington, Texas. The project in Dallas should cut the city's energy load by 1,500 kilowatts. And in early July, the Sacramento Municipal Utility District (SMUD) announced that Elk Grove, California, is installing LED signals in 70 intersections. The project will reduce peak demand by 44.3 kilowatts and save the city about $30,000 in energy costs each year. See the press releases from NYSERDA, ABM, and SMUD (PDF 102 KB).
