5 to 10 percent of your household electricity bill could be due to leaving large electronics like your TV, computer, or DVD player plugged in when not in use. Other devices such as cell phone chargers draw electricity if you keep them plugged in after the charging is done, which is why they often feel warm to the touch.
You can prevent this by plugging devices into a single, surge-protected power bar, or unplugging smaller devices like laptops and camera chargers once they are done charging.
