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.<>

桌面电脑的自动电源管理

有研究表明，许多台式个人电脑和外围设备在不使用时一直开着，浪费能源。作者使用定制的活动监控软件监测了33台台式电脑的使用模式，并预测如果电脑在60分钟不活动后自动关闭，平均电脑能耗将降低71%，平均峰值电力需求将降低36%。一种自动电源管理系统的现场试验，设计为在指定的不活动时间后关闭计算机和外围设备，使计算机平均能耗降低63%，平均峰值电力需求降低35%;视觉显示单元平均能耗降低82%。所有这些节省都是随着时间的推移而保持的。
