VAMPIRE ELECTRONICS:<\/span><\/h3>\n\n

HOW MUCH POWER DO THESE DEVICES REALLY DRAIN?<\/h3>\n\n

Can you save \u00a3\u00a3\u00a3s by switching off appliances at the mains, as suggested by some headlines? <\/strong><\/p>\n\n

\"\"<\/figure><\/div>\n\n

In April, British Gas published a report claiming households could save an average \u00a3147 per year on their energy bills by switching off devices that drain power when left on standby. <\/p>\n\n

The finding sparked the latest conversation about so-called \u2018vampire electronics\u2019 \u2013 devices that consume electricity when they\u2019re on standby mode or at other times you may not think they are \u2013 such as phone chargers plugged in at the wall but not connected to a phone, which will add a few pence to your bill. <\/p>\n\n

So how much power are these devices draining, and can we do anything about it to lower our bills? <\/p>\n\n

In its report, British Gas named set-top boxes, satellites, internet routers and TVs as the top three worst offenders when it comes to wasting money by being unnecessarily left on standby. Microwaves, games consoles and computers also drain a lot of energy on standby, it said. <\/p>\n\n

It used a survey carried out by YouGov to understand appliance use in UK households in April 2022, and combined that with their latest energy prices to understand the potential cost of vampire gadgets, a spokesperson for British Gas said. <\/p>\n\n

\u201cThis is a \u2018could\u2019 scenario and \u2018up to\u2019 this amount \u2013 this is based on what people are telling us, so it\u2019s not an exact science but our aim is to start the conversation to highlight the tips around turning things off when not in use,\u201d the spokesperson said. <\/p>\n\n

\u201cA good top tip is to replace things with more energy-efficient models when you can and we especially see big savings from items like washing machines and dishwashers amongst our customers.\u201d <\/p>\n\n

Craig Melson, associate director for climate, environment and sustainability for trade body techUK, says it\u2019s hard to calculate a figure for the average percentage of bills which come from vampire devices as there are too many variables. <\/p>\n\n

\u201cWe all have different tariffs, and some people use flexible energy services and smart meters to lower bills and have differing devices,\u201d he says. <\/p>\n\n

Others have also attempted to name a figure, however. <\/p>\n\n

Energy Saving Trust advises that households can save around \u00a355 a year just by turning appliances off standby mode.<\/span><\/p>\n\n

\u201cMost electrical appliances can be turned off at the plug without impacting their programming,\u201d a spokesperson said. <\/p>\n\n

\"\"<\/figure><\/div>\n\n

An earlier 2012 study highlighted home entertainment systems, VCRs and printers as high users of energy on standby mode. And another 2017 study cited Energy Saving Trust findings in 2014, which stated that standby demand can range from 9 to 16 per cent of a household\u2019s total electricity consumption. <\/p>\n\n

\u201cThe European Union has regulations on standby consumption of electronic devices in order to minimise the amount of electricity being used on standby\u201d <\/em><\/strong><\/span><\/p><\/blockquote>\n\n

But the problem with using older studies as a basis for understanding how much money we are currently wasting due to vampire devices is that standby modes have become far more energy efficient in recent years. <\/p>\n\n

\u201cSince the mid-2010s, the European Union has had regulations on standby consumption of electronic devices in order to minimise the amount of electricity being used on standby,\u201d says Sara Walker, professor of energy at Newcastle University. <\/p>\n\n

This has led most new devices to use far less energy than older ones. Meanwhile, Walker notes, the number of devices that we own, and the number that are internet-enabled, has increased. <\/p>\n\n

\u201cAlthough one device might use less, overall, we\u2019re still using about the same amount of electricity for our appliances, because we\u2019re using them more, and we own more of them,\u201d she says. \u201cWhen you\u2019ve got 10 or 15 of those in the house, as opposed to two or three, it can still add up over a full year.\u201d<\/span><\/p>\n\n

\"\"
We\u2019ve all got more appliances in our homes now, so it makes sense to switch them off when not in use<\/figcaption><\/figure><\/div>\n\n

Turning off these devices at the plug when not in use is a fairly easy win on energy bills, says Walker. <\/p>\n\n

\u201cObviously, this is a no-cost measure, which has its advantages for people who are really struggling with their bills,\u201d she says. <\/p>\n\n

However, manufacturers should also make sure they make this easy for us, she adds. For example, by making sure you don\u2019t need to reset a clock to make a device work when you turn it back on. <\/p>\n\n

Melson says the rollout of smart meters in the UK is also helping by informing people how much they are spending on electricity. Meanwhile, investing in low-cost smart plugs and smart home tech \u2013 which can cost under \u00a320 \u2013 allows you to power devices down using your phone. <\/p>\n\n

However, Walker explains that for most people, gas consumption is a larger part of overall energy consumption than electricity. <\/p>\n\n

Small measures can help here too, such as using the shower instead of the bath to cut down on hot water demand, draught-proofing by closing the curtains and using draught excluders on doors, and wearing warm clothing. And for those who can afford it, insulation \u2013 starting with the loft \u2013 is a great way to reduce the heat loss, she adds. <\/p>\n\n

Walker notes that our electricity consumption today is connected to social networks and the way that we like to use our free time. Much of our energy use comes from surfing the internet, streaming or watching television, or cooking. <\/p>\n\n

\u201cSome of that is a personal choice, but even so the price that we pay for the energy in order to do those things is outside of our control, it\u2019s market forces,\u201d she says. \u201cAnd there\u2019s a limit to our individual power to reduce that.\u201d <\/p>\n\n
