It is always a consideration whether the further use of an older device does not require less energy or water than the production of a new, energy-efficient device. Therefore, the energy requirement along the entire product life cycle (from production to use to disposal) must be considered.
Sometimes someone needs a different device and can't afford a new one - then a used device from someone who has bought a new, more economical device, of course, also makes sense. With some devices, the top values are only achieved with large quantities, i.e. washing machines with a lot of capacity. It is to see whether the top values also apply with lower filling quantities, for example for single households.

LED 'light bulbs' are now available for really all lamps, even with pleasantly warm light colors.

Motion detectors make sense in all rooms including outdoor areas, where we potentially let the light burn for too long, for example in the hallway, basement, garage, etc. Of course, it is important that the light does not stay on for too long.

Standby power consumption is often reminded and extrapolated. For example, if a TV consumes 5 watts in standby, that is 120 watt hours (Wh) per day, i.e. about one eighth of a kilowatt hour, which costs about 35 cents. So hardly anyone will get up from the sofa for 5 cents a day and press the switch on the TV, or turn off the WLAN router at night, or shut down the computer. Or is it? And how many watt hours could be saved daily in all households? Would this consideration influence your actions?

Modern lamps require little electricity, and yet it is worthwhile not to let them burn unnecessarily, for example when we are not in the room for a long time.

Apart from the fact that every device can have a high power consumption, a refrigerator is not regularly defrosted, the door seal is leaking, the washing machine is driven with too high temperatures and spin numbers, etc., there are still some unnecessary things that consume a lot of electricity:
Tumble dryer, sauna, dehumidifier, pond pumps, aquarium heaters, terrace heaters, etc.
The easiest way is to see to what extent you deviate from the average consumption in Germany and then think about what it is. If you are charging an electric car at home, you should see what can be attributed to it (either the car offers this evaluation or you use a separate electricity meter for this).
