The list and versatility of electrical appliances increases each year, they
all consume electricity.
A few need to be left on continually, but the vast majority should turned off at the
wall outlet, power strip, or disconnected when not in use.
There is an argument to the effect that electrical appliances should each be supplied with
a warning label, ‘Using this equipment threatens global warming, use it sparingly’.
Much electrical equipment has one or more standby modes. Manufacturers are being persuaded to
make their equipment, and especially the standby mode, more energy efficient. Older equipment is
often very energy inefficient, especially in standby mode. The author has some stereo equipment
that, in standby mode, consumes more than 60% of the energy it uses when being used.
What can I do to reduce electrical appliance energy cost? How to reduce clothes drying energy use
- Turn all appliances off when they are not being used, the
amount of electricity used by appliances
is surprising.
- Do not leave appliances on standby.
It is estimated that electrical equipment needlessly left in standby mode wastes 5% of total residential
electricity. If any appliance has a power module that plugs into a wall or is a separate unit, each
typically costs $5 a year even if the appliance is turned off. If you have a number of telephones,
a rechargeable TV, an electric toothbrush, or battery powered recharging units unplug them or switch
them off at the wall outlet when not in use.
- Computer equipment, computer speakers, LCD monitors and printers consume a surprisingly high amount
of energy when shut down. Power them via a switched outlet or a switched power strip. A typical computer
system costs $20 a year in standby mode or in shut down mode. A laptop charger costs typically $10 per
year when plugged into the main supply but not connected to the laptop.
- A modern automated home heating and cooling system typically continually consumes 15 to 25 watts, this
costs around $20 in standby mode, older system use far more energy. When neither home heating or cooling
is required turn the system off at the fuse box.
