If you’re anything like me, while you’ve been working from home you’ve found yourself checking the contents of your fridge every hour or so. Maybe you’re taking a break from work, or looking for inspiration, or hoping that someone else has quietly filled the fridge with snacks. (Why doesn’t that ever happen?)
In any case, every time you open the fridge door and lean on it, re-evaluating the unchanged fridge contents, you’re effectively raising your electricity bill by a tiny fraction.
It’s hard to get an accurate estimate of how much of your fridge’s running costs come from leaving the door open. According to an often-quoted figure from the publication Home Energy, 7% of your fridge’s electricity use is accounted for in this way.
A 2009 study by the University of Bath suggests that it may be more, with a family’s use of a fridge charted and user related losses in electricity (from leaving the fridge door open) accounting for 0.248 kWh per day. The average cost of energy per day in the UK is about 14.37p per kWh, so this is about 3.5p per day, or £13 per year. Still, fridges are much more energy efficient than they were in 2009.
Interestingly, this same study posits that a company could create a fridge with a glass door to minimise this wastage.
LG’s range of new InstaView Door-in-Door fridges does just that. One of the doors has a glass panel that, when knocked on twice, illuminates to let you see into an easy access compartment that you can fill with your most-reached-for snacks. Then you can make the decision as to whether or not it’s worth opening it.
LG is not claiming that it’ll save you money, but the company does contend it’ll help keep food fresher for longer. However, if tech like this became the norm, it’s the sort of small, incremental change that could help us all to conserve energy.
LG has several fridge freezers in the InstaView range, including the LG GSX960NSVZ American-style smart fridge freezer in premium steel.
It has 405 litres of fridge space and 196 litres of room in the freezer and it measures 179 x 91.2 x 73.8cm. It also has a water and ice dispenser (when plumbed in) and is wi-fi enabled, so you can adjust the temperature from an app on your phone.
It’s available from Currys PC World for £1,899.99. Other stockists of the range include John Lewis and AO.com.
