New year, new you! Start the decade off right with these electrical habits. 1. Replace regular light bulbs with LEDs. Survey all of the lights in your home and identify any non-LED ones. You can do so by carefully placing your thumb on top of the bulb. If it’s hot to the touch, it’s a non-LED light bulb. Once you’ve located all non-LED bulbs, replace them with LED light-saving ones. Why? They use 75% less energy than traditional incandescent bulbs and last 35-50 times longer.
