In Western countries, electricity, gas, and water are not
luxeries 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 account
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
