Even with the best of intentions, many of us leave our TVs, lights and computers on when we’re not using them…and it costs! But we probably knew that already. What we might not know is that even when our appliances are on standby (so not really off), they’re using energy and costing money.
The types of appliances that might operate on standby in our homes are a washing machine or dishwasher that is still on after the cycle, anything that has a display that is always on (like a microwave) and anything with a remote control.
But the appliances that suck the most energy are those that include a black box power supply, often called a ‘vampire’, between the appliance and the plug. The black box is responsible for converting AC electricity into DC electricity and the sensors and circuitry inside this box need to monitor what is happening with the device more or less constantly. This uses varying amounts of power, depending on what type of appliance it is, how old it is and the way it has been designed. The point, however: you pay for it.
Experts say that it’s not a single appliance left on standby that is a problem but rather the cumulative effect of many appliances left on. So, for example; a computer display in full use uses up 65 watts (68p per month) but still uses 12 watts when in sleep mode (10p per month). When off it uses 0.8 watts (1p per month). In and of itself, this is not a great amount but if you’re leaving, say, 50 appliances on standby; each one could add up to £3/year but altogether that’d make £150/year. This is a lot, especially when the cost can be avoided!
The solution: turn your appliances off at the plug.
In the UK, 15 per cent of domestic electricity is attributed to appliances on standby. Visit Draftlogioc.com for a list of the power consumption of typical household appliance, and for more energy-related information, contact the team at AACooper on 01689 485007 or firstname.lastname@example.org.
