Do night lights use a lot of electricity?
A single 1.5-watt night light used for 12 hours each day uses about 0.4 percent of the total electricity used for lighting an average U.S. residence. A 7.5-watt night light burning for 12 hours uses about 2 percent of the total electricity used for lighting.
