  2. Dependency on Computers • Computers are responsible for 40% of energy consumption by office equipment. • In 1993, International Data Corp. estimated that there was 1 computer for every 44 humans on earth. • Today, 575 million PCs are in use globally. • That number is expected to double by 2010.

  3. Computers do contribute to CO2 emissions • Leaving your computer on twenty four hours a day, 365 days a year, helps contribute to 1500 Ibs of CO2 emissions into the atmosphere. • Not to mention, the costs; the annual fees range from $115-$160. • The number of trees needed to offset the imbalance, are between 100-500 per computer.

  4. Just how much energy? • Computers draw 270 watts of power (including the monitor). • A watt is the maximum power drawn by an appliance. Watt (w) = current (I) * voltage (v) • Kilowatt-hour is the unit used to describe the power produced by an energy source: 1 kwh = 1000 watts sustained for one hour.

  5. How to calculate annual operating cost watts * hours used per day * days used per year/1000 = Kilowatt hour consumption

  6. Myths • Shutting down computers frequently may cause harm to the hard drive. Actually, this statement is false; your computer may last longer by shutting it down because mechanical wear and heat stress are reduced. • Turning the computer off and on actually consumes more energy than leaving them on. Not true; energy consumed by a CPU to boot up is far less than the energy used by a unit when left on for over 3 minutes.

  7. Myths (Continued) • Computers do not need to be put in sleep mode, as they use the same amount of energy when idling. Wrong; Sleep mode reduces energy consumption by 85%. • My screensaver “stores” energy. This is the most commonly misinterpreted conception; Screensavers can keep your system in an active state, thereby preventing power management from putting your computer into energy-saving sleep mode.

  8. What are the steps one needs to take to help and what are the benefits? • Taking the Architecture Library, for example, which currently leaves all twenty two computers on 24/7, could save thousands annually. • Just to have one computer on twenty-four hours a day, three-hundred sixty-five days a year, will cost $121.69 per year. • The Architecture Library has twenty-two computers; The yearly costs is estimated to be $2,677. • If the Architecture Library were to shut down all their computers for 9 hours a day, they could potentially have a savings of 19,521.9 kilo-watt-hours.

  9. Benefits (continued) • That translates to an annual money savings of $1,003.94. • With the savings earned the staff can purchase new computer equipment that is energy efficient, and they may even by more new books. • Replacing computers with new Energy Star approved ones (Appliances’ that are energy efficient).

  10. Energy Star? • Energy Star was first introduced in 1992 by the Environmental Protection Agency (EPA) as an voluntary labeling program to promote energy efficient home and office products. • Computers and monitors were the first labeled products. • Energy Star, now, has partnerships with over 8000 private and public organizations.

  11. Energy Star (continued) • Energy Power Management features place inactive CPUs and monitors into a low-power sleep mode. • Comes standard in Windows and Macintosh operating systems. • Monitor Power Management (MPM) can help you save up to $55 per monitor annually, by simply placing your inactive monitor into a low-power sleep mode. • Computer Power Management (CPM) helps save an additional $45 per computer annually by also placing it into a low-power sleep mode. • Here are just a few of the leading organizations that have switched to the Energy Power Management System: Citigroup, Proctor and Gamble, Harvard University, Ford Motor Company, General Electric and Wal-Mart. • This is part of the Million Monitor Pledge; a campaign to address efficient power management. • To put into perspective, once General Electric completes its initiative, it will save nearly 42 million kilowatt hours per year. Forty-two million kilowatt hours is enough electricity to light up 400,000 homes per month.

  12. For Windows 98/ME/2000/XP: Select Start, Settings, Control Panel and Display. Choose a predominantly black screen saver and set it to wait for 5 minutes. Click on Settings to reach the power management settings. Click the Shut off Monitor box and set for 10 minutes. Click Ok or Apply. To get settings for other models refer to the Energy Star website: http://www.energystar.gov/index-cfm?c=home.index For Macintosh: Select System Preferences from the dock (OSX) or click the Apple and select Control Panels (OS9). Select Energy Saver. Under the Sleep tab you can enable your computer, display, and hard drive to go to sleep mode after a period of inactivity. How to activate the Power Management Settings
