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.
