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 household, lighting accounts for 10 percent to 15 percent

of electricity bill. However, this amount can be reduced by replacing an ordinary 100-

watt light bulb with 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 invocations will save money as well as conserve the Earth’s resources.
