Now there are some tips for saving electricity. One of them is to always unplug. On some devices, however, this isn’t a good idea.

Kassel – In view of the current energy crisis, many citizens are planning to save electricity. Not pulling the plug out of the socket after charging can be a real energy hog.

However, there are also things that are best left permanently connected to power. Especially with three household items, it is advisable not to unplug. You can find out which ones are here.

Energy saving in the house: some devices do not need to be disconnected

To the Wi-Fi router other electrical devices, such as a smart TV, are often paired. As soon as the router is without power, they are also disconnected from the WLAN. This can cause power-up problems, for example, settings often need to be reprogrammed. There can also be update issues, as these are usually done at night. You should therefore think twice before turning off the WLAN router at night to save electricity.

Also to OLED TV better not to unplug. The TV automatically updates its pixels in the background. If it is disconnected from the network, the update process will be aborted. If this happens too often, it can lead to a pain in image quality, he writes Therefore, we recommend that you ask the manufacturer for the possibility of periodically disconnecting the TV from the power supply.

Energy saving: unplugging can make sense – you shouldn’t do this with the printer

He will do it Printer completely unplugged from the power supply, restarting will cause the printer to be readjusted and cleaned. During cleaning, the printer consumes a lot of ink. Additionally, a printer hardly consumes electricity even when plugged in, so the potential savings are hardly significant, he writes

However, some cables should definitely be unplugged from the socket, especially charging cables for smartphones, laptops and other equipment, which consume electricity even when no devices are connected. A study from Switzerland shows how much energy is consumed even without recharging. In this “the power consumption of the mains plugs was measured,” explains SWR environmental editor Dominik Bartoscheck. “The worst model used more than one kilowatt-hour of electricity per year, just to be plugged in.”

“Annual consumption of over a kilowatt hour of electricity”: Unplug these devices to save energy

The consumption of the chargers is linked to the fact that a transformer has been installed, which per project works constantly as soon as it is connected to the electricity grid, reports the SWR further.

Not only do the charging cables need to be unplugged, Bartoscheck also recommends saving energy in the kitchen if the kettle and toaster are not left connected. This also has another advantage, because it reduces the risk of fire. It is therefore worth checking which plugs can be pulled out of the socket. (Kilian Baeuml)
