Use alternating current electricity
or rechargeable batteries instead of disposable
ones. This saves your money as well as the environment.
Rechargeable battery is 50 times more durable than
disposable battery. Take a head-set radio for example.
By using rechargeable battery, you can save 1,700
dollars and reduce 1 kg of solid-waste for 5,000
hours of listening, as compared to using disposable
battery. |

Two types of rechargeable batteries
are available on the market - nickel cadmium (NiCd)
and nickel metal hydride (NiMH). The latter is more
environmental friendly with higher electrical capacity
and without the toxic heavy metal - cadmium, which
is difficult to treat after disposal. |

Use electric fan instead of air conditioner
whenever possible. It can reduce the electricity
use by tenfold. A 1-bps air conditioner will dissipate
960W (cost $0.68) electrical energy within hour
while an electric fan only uses 75W (cost $0.06).
For using 10 hours a day, an electric fan can save
you $200 on your electricity bill. |

When air conditioning must be used,
the temperature shall be set at the optimum 25.5¢XC.
Lowering 1¢XC is equivalent to a 6% increment of
total energy consumption. |
| 5. |
Energy saving light bulbs consume less electricity
and produce less heat. They save 75% of electricity
and are 10 times more durable than ordinary ones.
Besides, less heat will be given off and hence reducing
the need for air conditioning. |
| 6. |
Adjust the fridge temperature with seasonal need;
do not maintain it at a very low temperature. A
one-degree-Celsius decrement is equivalent to a
5% increase in energy consumption. Furthermore,
a 10¢XC increase in the surrounding environment will
increase the energy use by 10-20%. In order to facilitate
heat dissipation, sundries should be removed from
the fridge top and a distance of at least 10 cm
should be maintained between the back of the fridge
and the wall. The fridge should be placed in a shady
place away from direct sunlight or any heat source.
