Standby Energy Consumption

Most households contain appliances which consume electricity even when they are not operational. This is generally referred to as ‘standby’ energy consumption and can amount to over 10% of total electricity used in a typical home.

Appliances and equipment with a standby mode include VCR’s, televisions, home entertainment systems, air conditioners, battery chargers, whitegoods (except refrigerators), and other equipment which consumes power while not performing its primary function.

The following table provides a guide to the standby wattage and average annual standby energy cost for various appliances.

Average standby Annual cost

Energy use (watts) (approx)
Television 10 $15
Clock radio 4 $6
VCR 8 $11
Stereo 10 $15
Mobile phone charger 1 $2
Personal computer 2 $3
Computer monitor 5 $8
Printer 8 $11
Microwave oven 4 $6

    Hello. I am worried because I don t know if the triphasic savers are scam or true
    These triphasic savers are made in China with germany technology. They correct the potential factor and save energy till 30%. Please, I need your advise. Thank you

    Probably won’t save power. However on mine sites they are more correctly known as “power conditioners. They will correct power factor and therefore protect electronics.
    regardless of the arguments about true power and apparent power. The current in an inductive load – anything with a motor transformer or ballast – will run cooler ansd therefore last longer.

    What is the standby power consumption of a 65W Laptop AC adapter (when it is not connected to laptop for charging)?

    Having my microwave, my stereo, and my harddrive recorder on standby is the only way to preserve the time and date settings in the appliances – correct????

    There is a way to genuinely save up to 40% of power bills by utilisation of tariff 33 in QLD. It requires a slight rule change to be fully legal but levels out demand.
