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 100watt 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.
