Chargers for mobile phones, tablets or laptops are power guzzlers when permanently plugged into sockets. Tom Raulian, project manager for Energy Efficiency Dialog in Dena, explains: “Your power consumption can be judged, among other things, by the fact that they get hot. It is recommended here to constantly pull the plug or Multiple sockets use an on/off switch.”

You can also connect electronic devices that you use only for a few hours a day and that otherwise consume a lot of power in standby mode with an on/off switch to multiple sockets or socket strips. These include TV receivers, soundbars, coffee machines with integrated clock displays, microwaves and stereo systems.

A television in standby mode incurs electricity costs of more than 35 euros per year. For a stereo system, that’s a cool 40 euros. A DVB-T receiver also costs a good 30 euros a year. So with these three electrical appliances, you already spend over 100 euros per year.
