<b>Unit 7: SAVING ENERGY</b>
<b>Period 44 : </b>
<b>How to save electricity</b>
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 and 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.
