Conversion to LED lights could save the U.S. $115 billion in energy costs
LEDs can last 75,000 hours or longer and consume far less power than standard incandescent bulbs. Only about 5 percent of the energy that goes into conventional bulbs actually turns into light; the rest gets dissipated as heat. If 25 percent of the lightbulbs in the United States were converted to LEDs putting out 150 lumens (a measure of light output) per watt–higher than the most current models–the country as a whole could save $115 billion in utility costs cumulatively by 2025, according to University of California Santa Barbara professor Stephen DenBaars.
