Campbell76 posted a topic in Science and TechnologyA U.S. Department of Energy study recently estimated that over 2 billion kilowatt hours of electricity could be saved if U.S. households replaced their traditional inefficient incandescent holiday lights with LED lighting. The estimated energy savings would be enough energy to power about 200,000 homes for an entire year. Interestingly, this study did not even consider commercial uses of holiday lighting. Most commercial displays are much larger and therefore use much more energy. The annual energy savings could be enormous if the study took into account average annual commercial consumption. In addition to the remarkable potential for energy savings, LED lights will last for up to 20 years considering normal holiday use. Traditional incandescent holiday lights may need to be replaced as often as every two years. That's a lot less useless holiday lights to put in our nation's landfills. The average retail price of LED Christmas lights[/url:afc9e] continues to decrease. However, even at current pricing the lights are a true bargain considering the life cycle of the product, energy savings, and the decreased impact on the environment.
