LED is a highly energy-efficient lighting technology and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs — especially ENERGY STAR®-rated products — use at least 75% less energy and last 25 times longer than incandescent lighting.
Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 Terawatt-hours (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1,000 megawatts each), and a total annual savings of more than $30 billion at today’s electricity prices.
