| Tiivistelmä: | In order to save money some institutions have been considering programs to induce office workers to shut off (cycle) their PCs when not in use for short periods. The authors explore the costs and benefits for turning off the hardware and describe them in simple equations. Typical office worker salaries and typical energy usage for PCs are combined to determine how much worker time can be spent on computer cycling for this action to be economically justified. The authors show that the value of workers' salaries makes improvements in hardware efficiency and automatic monitor shutdown (using techniques now common in laptop computers) relatively more attractive than programs to modify office workers' behaviour. |
