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.
