One of my favorite things about the holidays is all of those colorful, twinkly lights; they make outdoor shopping malls feel more like Disneyland. But those of us who’ve cringed at opening the electric bill in January know all too well those little sparkly beauties come at a price to us and the environment.

If the idea of letting go of your old decorating tradition is too much to bear, commit to replacing your old incandescent lights with eco-friendly LED light bulbs. LED lights are mercury-free, four times more efficient than an incandescent bulb and last 10 times as long. According to the City of Seattle, the savings are considerable when using LED holiday lights: The comparative cost for a season of holiday lighting (based on ten strings of lights burning 8 hours a day for 30 days at City Light’s 2nd block residential rate of $0.0853 cents per kilowatt-hour) is $127.67 for large lights, $7.20 for mini lights, and $0.72 for the new LED lights.â€?
