When a device is fully charged and the plug remains in the socket, the charger will still consume power. You will notice this in the heat that the charger continues to emit. Also, many devices consume electricity when not in use. Typical examples are the laptop, modem, TV, and printer. Collecting that excess energy consumption is called sleep consumption or standby consumption.

Save up to € 11.76 per charger

Dutch energy supplier Vattenfal has calculated that an adapter that is unnecessarily plugged into the socket consumes around 2 watts per hour. If the device remains in the socket continuously, the consumption increases to 17.52 kilowatt hours per year. At the current average price via Mijnenergie.be of 67.15 euro cents per kilowatt hour, you pay 11.76 euro on an annual basis.

At first glance it doesn’t look bad, but when all the family members leave their chargers in the socket, the bill quickly rises to a few tens of euros. Including the continuous standby consumption of computers, TVs and other devices, a price of one hundred euros is realistic.

How to detect and manage it?

So it pays more than ever to tackle those standby consumers. You do this by first detecting unnecessary consumption. This is possible with the help of an energy meter that plugs into the socket and is monitored via an app. You can track your energy consumption in real time through these apps.

An alternative method is to walk around the house and find out where the lights are on or which appliances emit heat. Then it’s a matter of unplugging the necessary plugs from the socket or replacing any energy-consuming appliances with new, cheaper models. A power strip with on / off switch gives you the ability to disable various devices with a single movement.
