smart stripsThere are smart electric plug strips that use a timer system or infra-red/motion sensors to turn off “ghost” loads or electric loads that are not being used when no one is around. Occupancy sensing plug strips detect the presence or absence of a person, and automatically turn  equipment  on and off accordingly. These smart plug strips usually have one or two outlets that are always on, meaning that they remain constantly powered and are not affected by the occupancy sensor.

Research suggests that a smart plug strip used with office equipment (at home or at work) can save from 25 to 180 kWh per year and that a smart plug strip used with home entertainment equipment like TVs, DVDs, and amplifiers can save from 25 to well over 100 kWh per year.
