Ghosts & Phantoms in Electronics
True or False?
When an appliance is off, it does not use any energy.
False. This is a myth. Many devices actually consume energy even when off. Televisions, chargers, clocks, and other devices may have “vampire”, or “phantom”, loads, requiring standby power even when the device is “off.”
Though many of the standby power for individual devices can be small, it adds up to about 5% of electricity usage. Plugging devices into power strips, and actually turning them off, will reduce your energy consumption. Some power strips are enabled with occupancy sensors that will turn them off when there’s no activity in the area.
