“How much
energy do your
appliances use?”
energyanswers
appliance guide
To help you be
more energy efficient,
this guide has been
put together by our
energyanswers team
to give you an idea
of the typical energy
consumption of the
appliances in your
house.
Some of the average
energy usage may
surprise you, but it
could help you see
where your household
can make the biggest
energy savings.
Things you
should know
when reading
this guide
The energy usage and cost figures listed in the following
tables should be taken as a guide only. Energy usage is
presented as an average estimate while costs and usage
will vary according to things like the size of your home
and your personal preferences.
Estimated costs are based on the average residential
tariffs available in the Essential Energy network area
as at 1 November 2011 which are an electricity rate
of $0.26 ($0.26228) per kilowatt hour (kWh) and
a gas rate of $0.02 ($0.0200) per megajoule (MJ)
excluding GST. Due to your location, different tariffs and
the exclusion of the Service Availability Charge (SAC),
results may not be an accurate reflection of your bill
and actual costs may vary between households.
Figures for thermostat-controlled appliances have also
been averaged to take into account appliances that are
normally on continuously, and switch themselves on
and off to maintain pre-selected temperatures.

“I knew that turning appliances
off at the power point was good
for saving energy, but did you
know that standby power can
account for up to 20% of the total
energy use for that appliance.”
