In April, British Gas published a report claiming households could save an average £147 per year on their energy bills by switching off devices that drain power when left on standby.
The finding sparked the latest conversation about so-called 'vampire electronics' - devices that consume electricity when they're on standby mode or at other times you may not think they are - such as phone chargers plugged in at the wall but not connected to a phone, which will add a few pence to your bill.
So how much power are these devices draining, and can we do anything about it to lower our bills?
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.
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.
"This is a 'could' scenario and 'up to' this amount this is based on what people are telling us, so it's not an exact science but our aim is to start the conversation to highlight the tips around turning things off when not in use," the spokesperson said.
"A 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."

COULD MARINE CLOUD BRIGHTENING HELP US FIGHT CLIMATE CHANGE?
The theory behind marine cloud brightening is that brighter or whiter clouds reflect more sunlight back into space.
IS IT SAFE TO RUN EVERY DAY, OR SHOULD I DITCH MY RUN STREAK TO SAVE MY KNEES?
A running streak, where you run every day without taking rest days, can be highly motivating and beneficial for overall fitness. Running is great cardiovascular exercise and isn't to be discouraged (and finding a routine with some consistency is great). Getting a bit of exercise as often as possible is also hugely beneficial for your mental health.
WHAT MAKES THE MEDITERRANEAN DIET SO GOOD FOR US?
The Mediterranean diet may help you live longer, especially if you also adopt the lifestyle of people living near the Med during the 1950s.
WHAT IS MEXICO'S BLUE HOLE?
The world's deepest blue hole (marine sinkhole) lies off the coast of Mexico's Yucatán Peninsula. It's at least 420m (1,378ft) deep, but explorers still haven't found its bottom.
HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?
Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys. It plays a critical role in various bodily functions, including regulating metabolism, reducing inflammation and helping the body respond to stress. While essential for our health, chronic elevation of cortisol levels can lead to several issues.
THE LUNGFISH
In 1836, European scientists discovered a peculiar animal from the River Amazon that they struggled to identify. Its eel-like body was a few feet long and its air-filled lungs persuaded anatomists it must be a reptile.
ARE WE THE ONLY SPECIES TO HAVE BEEN THROUGH A STONE AGE?
The Stone Age might conjure up images of early humans, sitting around a campfire or hunting prehistoric beasts, but evidence shows that we're not the only species that has learned how to work with stone tools. Wild chimpanzees (Pan troglodytes) use stone tools to crack open nuts.
Should we scrap daylight saving time?
Most of us look forward to the extra hour we get in bed every October, but researchers argue that changing the clocks twice a year harms our health

SCIENTISTS ARE USING ELECTRONIC TAGS AND SATELLITES TO TRACK WILD ANIMALS AND CREATE A DATA NETWORK THAT COULD HELP US ADDRESS THE BIODIVERSITY CRISIS
MUSIC FOR A DISTRACTED GENERATION
The number of things competing for our attention is often overwhelming. Can dreamy soundscapes created with neuroscience help our bewildered brains to concentrate?
