  1. Saving Energy in your Office with IT Equipment Joyce Dickerson, Director, Sustainable ITDepartment of Sustainability and Energy Management

  2. THE BIG PICTURE: IT & CO2 EMISSIONS • IT Industry Energy Usage • Datacenters use 3% of the total energy used in the US, and office computing is another 1% (DOE/LBNL/Energy Star) • IT Industry’s CO2 footprint is equivalent to that of the Aviation Industry (Gartner) • Emissions growth from IT is the fastest of any sector, especially in data-intensive disciplines • Office equipment accounts for 26% of the energy used in office buildings (State of CA) • Lighting = 22% • Chilled Water Subsystem = 28% • Energy prices expected to rise 6% per year (DOE) • PC Statistics • Average PC wastes ½ the energy delivered to it (Climate Savers) • 50 million tons of e-waste produced yearly worldwide (Green PC) • User Behavior • As many as 60% don’t turn computer off at night (PC Energy Report) • US, with 5% world population, uses 30% of world’s paper (reduce.org) • Typical office disposes 350 lbs waste paper/employee/year (NRDC)

  3. IT AT STANFORD • Faculty, staff and students • 40,000 desktop/laptop computers • 6000 servers • 10-20% of campus energy use from IT infrastructure • Number of computers growing 15% per year • Need to keep energy usage flat, or reduce, while increasing productive output of IT infrastructure So what can you do?

  4. 1. USE YOUR COMPUTER LONGER • Keep using what you’re using • Replace less often • 80% of carbon is from manufacturing, 20% from use • Upgrade components: hard drive, memory, graphics card, power supply, etc. • Replace with a laptop • Laptops use 80% less energy then desktop systems • fewer parts, need less packaging, less shipping • Recycle old machines • Make sure they don’t just get handed down • Look for machines designed for upgrades • Memory, processor

  5. 2. BUY WITH SUSTAINABILITY IN MIND • Buy only what you need • High-end graphics cards can use as much energy as CPU • Play fewer games… • Energy Star 5.0 • Establishes efficiency requirements to ensure energy savings • Electronic Product Environmental Assessment Tool (EPEAT) – www.epeat.net • Searchable database of computer hardware and set of holistic environmental guidelines • EPA + Hardware venders (Dell, HP, Apple, IBM, etc) • 20% of computers shipped in 2007 were EPEAT registered • Up from 10% in 2006 • Calculate environment benefits and cost savings

  6. 3. POWER MANAGEMENT … A FEW MYTHS • Turning off your computer harms it • PCs are built to withstand 40,000 power cycles • Historically, could damage hard disks. Not anymore (IEEE) • It takes more energy to boot a computer than it does to keep it awake overnight • The small surge of power to turn it on is much smaller then energy used to keep it on • Screensavers save energy • Use more energy – 42-114 watts • Originally designed to prevent burn-in, not save energy • Better to turn the monitor off • A computer that’s off uses 0 energy • Plugged in it draws ~2-3 watts for network connectivity, etc.

  7. POWER MANAGEMENT – COMPARING THE OPTIONS

  8. POWER MANAGEMENT IS AN EASY WIN Sustainable IT • Power Management comes with your computer • PC: Start/Control Panel/Power Options • Mac: Apple Menu/System Preferences/Energy Saver • Only 10% of PC’s have Power Management enabled (EPA) • Power management can save between $25-$75 in energy costs annually, per computer • Reduces energy used by approx 1/3 • Make it easy – activate Big Fix for the Dept • Already on 22,000+ across campus • Power Management enabled on 30% • Local IT centrally manages Big Fix Power Management • Turn off Monitors after 15 minutes • Local IT can customize for dept needs • Spin down disk, Sleep, Hibernate

  9. Big Fix Power Management deployment is managed locally, so you can help drive up your Group’s participation Ask your local IT staff why your percentage isn’t higher

  10. 4. OPTIMIZE PERFORMANCE • If it’s running slow, it’s wasting energy • Talk to local IT team about cleaning it up • Do your own computer cleanup: • Windows: Start/All Programs/Accessories/System Tools • Disk Cleanup -- Free up disk space • Disk Defragmenter – consolidates fragmented files • Clear databases of unnecessary content • The more data they contain, the more hardware is used in storing them

  11. 5. MONITORS • Hunt out the CRTs and get rid of them • Convert to flat panels • CRT uses 2-3x more energy the flat panels • CRT has lead & mercury – so dispose of properly • Choose a LED flat-panel monitor • Light Emitting Diode (LED) monitors are mercury free and recyclable • LCD, while better then CRT’s, contains mercury (CFL) • Turn off the Monitor using Power Management • Disable your screen saver • Hit the ‘Off’ button when you walk away • Uses zero energy

  12. 6.PRINTING • The Obvious Stuff: • Set your print drivers to default to double-sided • Local IT can set your printers to default double-sided • Do the same for your copiers • Print in DRAFT mode to save toner • Print to PDF and store electronically • Lots of free PDF making software: www.download.com • Use Print Preview to avoid printing errors • Only print ‘page 1’ of emails ... Avoid the chain • Squeeze the margins • Margins reduced from 1.25 to .75 in, nearly 5% paper savings • Use 100% Recycled Paper • Greenprint • See and select pages before printing • Average employee prints 6 wasted pages per day • Aardvark • Firefox extension – clean out graphics before printing • Track printer/copier sustainability with network tool • Most vendors have a multi-vendor tool • Xerox’s Sustainability Calculator, HP Webjet Admin

  13. 7. POWER SUPPLIES • All power supplies are not created equal • Older and many after-market ones are <80% efficient • Upgrade your power supply • 80 Plus Certification • >80% efficient • International Energy Efficiency stamp “IV” • >85% efficiency • Energy Star “V” • >87% efficiency • Always check power supply efficiency when buying any electronic equipment

  14. 8. BATTERIES • Replace your old laptop battery • Laptop batteries wear out • Same energy to achieve shorter battery life • Recycle and get a new one • Always recycle batteries: Contain lots of toxic heavy metal materials • Use them efficiently, so as to replace less often • Lithium-ion batteries • Last longer when kept from running below a 40-percent charge • Remove when plugged in • Trickle charge wears them out • iPods, cell phones etc. • Take it out of the case before charging • Cases trap heat and compromise battery capacity • Plug in more frequently, burn through # charges

  15. 9. KEEPING IT DIGITAL • Faxes • Scan and email docs rather then fax them • Get a Fax Server • Receive and send faxes via email • Scan your signature • Drop it on a Word or PDF Doc, make a new PDF, send back via email • Saves printing-signing-faxing-scanning-filing • Free PDF software at www.download.com • Look for most highly rated/downloaded

  16. 10. VAMPIRE PERIPHERALS • Target your peripherals • Up to 75% of total energy usage from when they’re off • Speakers, printer, monitor • Anything that has an AC Adaptor • Plug them into a Power Strip and turn off when done • Use a Smart Strip Power Strip

  17. 11. REUSE AND RECYCLE • Dispose of your old equipment properly • Toxic waste in electronics is substantial • Leaks into surrounding soils and water • Reuse, or recycle • Check with the manufacturer for take-back program • Reuse.stanford.edu • Recycle old equipment • Stanford Equipment – e-waste bins in buildings • Electronicrecyclers.com • Personal Equipment – look for ewaste recycle days • Aim for 0% to landfill

  18. 12. Start Measuring Things • Get a Kill a Watt meter • Test out your peripherals • Speakers are a surprising sleeper • Measure ‘Vampire’ energy drains

  19. 13. AUDIT, ACT & MEASURE AGAIN • Audit existing PC inventory • Run tests with the Kill a Watt meter • Baseline current energy consumption • Make Changes • Enable power management in your department • Replace power strips with Smart Strips • Disable screen savers • Replace CRT’s with LED Flat panels • Purchase EPEAT equipment • Set printers and copiers to double-sided • Track printer and copier usage with sustainability software • Repeat & Improve
