“…This therefore helped cut down on power wasted by idling computers. [12] Overall, reduction of power usage in computer labs is an important topic that needs to be explored, for both monetary and environmental benefits. Though there are many techniques, power management is a convenient solution that can be done on computers already in use.…”

There is a huge potential to save energy on computers and in university computer labs.With many computers sitting idle during nights and weekends when they are rarely used, power management techniques could have both monetary and energy savings. Through the use of a Watts Up? Pro ES power meter, the energy consumption of different computers and user activities was explored on the Kansas State University campus. Energy Star computers were found to be much more efficient for all activities, averaging 52% less energy use than the other computers tested. To implement energy management techniques (such as the use of Faronics PowerSave software), more studies need to be done on computer usage in the computer labs during the school year. This will allow for effective power management settings while balancing user convenience and energy savings.

“…The most important factor for saving energy is user behaviour, such as turning off devices at night or enabling power management (Newsham and Tiller, 1994;Webber et al, 2005). By providing adequate information as well as adequate tools, which can automate many of the user actions, it is possible to influence energy consumption reduction to a greate extent.…”

“…The user must be able to specify that a computer will never be switched off, regardless of keyboard/mouse activity, and that the computer will never be switched off if an application program is running (Bray, 2006). In other words, users must have the freedom to choose switch off criteria that is best suited to their own work patterns (Newsham and Tiller, 1994).…”

Abstract:Modern organizations depend on computers to work. Text processing, CAD, CAM, simulation, statistical analysis and so on are fundamental for maintaining high degree of productivity and competitiveness. Computers in an organization, consume a considerable percentage of the overall energy and, although a typical computer provides power saving technologies, such as suspending or hibernating components, this feature can be disabled. Moreover, the user can opt for never turning off the workstation. Well defined power saving policies, with appropriate automatic mechanisms to apply them, can provide significant power savings with consequent reduction of the power expense. With several computers in an organization, it is necessary to build the profile of the energy consumption. We propose installing a software probe in each computer to instrument the power comsumption, either diretly, by using a power meter, or indirectly, by measuring the processor performance counters. This distributed architecture, with software probes in every computer and a centralized server for persistence and decision making tries to save energy, by defining and applying organization level power saving policies.

“…Nighttime Status -According to Nordman et al (2000), 65% of desktop computers are off at night. Newsham et al (1994), about 20% of desktop computers are off during the daytime. According to Szydlowski et al (1994), desktop computers are active for 38% of the daytime and at low power for 62% of the daytime when the PM timer is set to 15 minutes.…”
