Two-thirds of Americans decorate their homes with holiday lights, and even small displays can add to high winter energy costs. Shorter, colder days make lights and heat pumps run longer, and hosting guests can raise appliance use.
Scott Dunning, a professor and certified energy manager, gives simple tips. He recommends swapping incandescent bulbs for LED lights. For example, a strand of 100 incandescent lights costs about $3, while 100 LED mini-lights cost $6. If lights run six hours a night for six weeks, incandescents can cost much more for the season than LEDs.
Solar-powered lights use sunlight and do not add to the electric bill when they get enough direct sun. Dunning also suggests using timers for outdoor inflatables to lower costs and cleaning solar panels so they work well.
