When you think about devices that consume a lot of electricity in your home, you probably don’t think of a modest internet router. But if you leave it on all day, it can consume as much electricity as a refrigerator.
Therefore, you should pay attention to the router’s energy efficiency before buying it and make sure it has the lowest possible energy consumption when turned on or in standby mode.
The German Federal Environmental Agency states that this is especially important if the router cannot be turned off because it also uses the phone line.
If that’s the case, the advice is to buy a router that can at least turn off the wireless internet when not in use.
