Many electronics continue to draw power after you turn them off. You’ll know because you’ll still see a glowing LED (light emitting diode) after you flip the switch. Your TV, cell phone charger, and printer are likely culprits. Make it easier to turn off those energy vampires by plugging them into power strips instead of wall sockets. That way, you need flip the switch only once to cut the flow of electricity to everything plugged into the strip.
