However with save Therefore of and
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 (21) save money. For most North American households, lighting accounts for 10 percent to 15 percent of the electricity bill. (22) However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy saving-bulb. These bulbs use a quarter (23) of the electricity of standard bulbs and last eight times longer. (24) Therefore, consumers can save about US7toUS7toUS21 per bulb. In Europe, there is a labeling scheme for refrigerators, freezers, washing machines (25) and tumble dryers. The label tells the consumers how much energy efficiency each model has, compared (26) with other appliances in the same category.
