LEDs are still one of the “low hanging fruits” of energy management and here’s why: projects like Groton, Connecticut’s LED street light conversion is saving $100,000 annually on energy and maintenance costs.
According to The Day, Groton’s public works department recently released a report claiming the town has seen a 67% reduction in energy use and greenhouse gas emissions since switching to LED streetlights from high-pressure sodium streetlights in February 2017.
The town began to devise an energy action plan in 2010 and soon realized the cost and environmental benefits of LED lighting. After receiving financial assistance from Eversource and Groton Utilities, the town replaced 1,500 streetlights between February and March 2017.
In December 2017, Energy Manager Today reported that the use of LEDs to illuminate buildings and outdoor spaces reduced the total carbon dioxide emissions of lighting by an estimated 570 million tons in 2017, according to IHS Markit. LED lighting uses an average of 40% less power than fluorescents, and 80% less than incandescents, to produce the same amount of light.
According to a recent US Department of Energy report, the number of LED installations has quadrupled from 215 million units in 2014 to 874 million units in 2016. Despite this staggering growth in the adaptation of LED lighting, LED market penetration is still at only 12.6%. The DOE’s goal scenario is 90% market penetration by 2035.
