For most North American households, lighting accounts for 10 percent to 15 percent of the electricity bill However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb These bulbs use a quarter of the electricity of standard bulbs and last eight times longer Therefore consumers can save about US$7 to US$21 per bulb.
