Abstract
It has been shown that many desktop personal computers and peripherals are left on when they are not being used, wasting energy. The authors monitored desktop computer use patterns on 33 machines using custom activity monitoring software, and predicted a reduction in mean computer energy consumption of 71% with a 36% reduction in mean peak power demand, if computers were automatically switched off after 60 minutes of inactivity. Field trials of an automatic power management system designed to switch off computers and peripherals after a specified period of inactivity produced reductions in mean computer energy consumption of 63%, with a reduction in mean peak power demand of 35%; visual display unit mean energy consumption was reduced by 82%. All these savings were maintained with time.<>
