And yes, even when turned off or on standby, your devices continue to consume energy. So when you count the number of devices plugged into your home, that’s a lot. According to the ADEME (Ecological Transition Agency), switching off appliances on standby can save up to 15% of your electricity bill (excluding heating and hot water). If the consumption of connected chargers is minimal, when there are several, it starts to do a lot, especially if you leave your devices connected to the end of the line. So take the reflex to unplug your laptop chargers. Tip: You can use power strips with a switch to turn off all devices at once. This will also allow you to preserve your phone batteries.
