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.
