@leobm @feld @lain @Datenegassie @nikitonsky Taking that value as an example, it would mean that your home is drawing a bit under 50W continuously for electronics in standby mode. A Mac mini drawing 0.5W (this is the actual specs of the device, turning it off reduces this to 0.1W) in sleep mode isn't going to impact that. Multiplying the other way, the yearly power draw of a Mac Mini always on in sleep mode is approximately 4.4kWh / year.
