NV Energy has some advice for holiday lighting tips to help customers save energy, and decorate safely this season. They suggest you switch to long-lasting, energy-efficient LED holiday lights whenever possible. LEDs use 90 percent less energy, and are cooler. Use a timer to turn off lights during daylight hours and other specified times. Don’t overload your electric circuits. Check fuses or circuit breaker panels to see what your home can handle, and stay well within the limits. Don’t run extension cords under rugs, around furniture legs, or across doorways. Outdoor lighting should have insulated electrical cords and be plugged into a ground fault interrupter-protected receptacle only. And never use electrical decorations on metal trees.
