Television, stereo system, computer, DVD player: they are all stand-by candidates that are usually not switched off. But that costs. Per household and year, the costs add up to well over 100 euros, depending on the equipment. So it switches off as often as possible, preferably via a socket strip with a power switch. You save even more energy if you turn down the brightness of the monitor, which is often set higher than necessary. In addition, there are devices that only appear to be switched off ("Scheinaus") or have no switch at all. You can easily test whether your device is really off: If the power supply remains warm even though you have switched off the device, current continues to flow. Socket strips with a power switch are also recommended here, with which you can also switch multiple devices on and off.
