Reduce energy use, increase data security 10:29 a.m., Oct. 13, 2005--Energy costs are increasing dramatically. The price increases affect everyone--at home and at work. On the UD campus, computers are an integral part of our work. However, many users aren’t aware of how much energy computers use. For example, a typical computer that is turned on for eight hours a day and 273 days a year (the number of days the University is in session) uses approximately $14 of electricity per year. However, if that same computer is turned on for 24 hours per day, 273 days of the year, that number skyrockets to $43 per year in electricity costs--a threefold increase. When comparing these two scenarios and taking into account that there are approximately 12,000 computers in use on the campus, it’s easy to see the large savings that will accrue to UD if computers are simply turned off at the end of the day. Besides reducing energy costs, turning off computers increases the security of the data on computers by making it inaccessible when the computer is not being used. The University's ongoing personal nonpublic information (PNPI) initiative stresses the importance of the security of personal information for all members of the University community. So pressing the “Off” button at the end of the day not only reduces energy costs, it increases the security of information on computers on the campus. For specific facts and figures about how much electricity computers use and some basic techniques to reduce the energy use, go to the UDLite web page at [www.udel.edu/topics/udlite].
