1.5.13 Unplug battery chargers when their use is not necessary

Description

Mobile phones, laptops, tablets and other devices are usually left plugged to their battery charger though they are already fully charged or they are in sleep mode. This generates phantom consumption which can be easily avoided.

Benefits

  • Energy savings up to 5% can be achieved

  • The battery life will be preserved

Limitations

  • Occupant acceptance

  • The energy savings potential depends on the efficiency and number of chargers, on the devices plugged and on the use made of them

Economic assessment

The cost is zero, although it is convenient to train and inform properly users on these issues.
