 UNIT 7: SAVING ENERGY * read
 In Western countries, electricity, gas, and water 
 are not luxuries but necessities. Companies now 
 realize that consumers want products that will not 
 only work effectively, but also save money.
 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.
 In Europe, there is a labeling scheme for 
 refrigerators, freezers, washing machines and 
 tumble dryers. The label tells the consumers how 
 much energy efficiency each model has, compared 
 with other appliances in the same category.
 Ultimately, these innovations will save money as 
 well as conserve the Earth’s resources. b) Answer the questions.
