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 Industrys 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 dont turn computer off at night
  (PC Energy Report)
• US, with 5 world population, uses 30 of worlds
  paper (reduce.org)
• Typical office disposes 350 lbs waste
  paper/employee/year (NRDC)

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 youre 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 dont 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

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 thats off uses 0 energy
• Plugged in it draws 2-3 watts for network
  connectivity, etc.

POWER MANAGEMENT COMPARING THE OPTIONS
10
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 PCs 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

11
Big Fix Power Management deployment is managed
locally, so you can help drive up your Groups
participation
Ask your local IT staff why your percentage isnt
higher

4. OPTIMIZE PERFORMANCE

• If its running slow, its 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

13
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 CRTs, 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

14
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

15
7. POWER SUPPLIES

• All power supplies are not created equal
• Older and many after-market ones are lt80
  efficient
• Upgrade your power supply
• 80 Plus Certification
• gt80 efficient
• International Energy Efficiency stamp IV
• gt85 efficiency
• Energy Star V
• gt87 efficiency
• Always check power supply efficiency when buying
  any electronic equipment

16
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

17
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

18
10. VAMPIRE PERIPHERALS

• Target your peripherals
• Up to 75 of total energy usage from when theyre
  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

19
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

20
12. Start Measuring Things

• Get a Kill a Watt meter
• Test out your peripherals
• Speakers are a surprising sleeper
• Measure Vampire energy drains

21
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 CRTs with LED Flat panels
• Purchase EPEAT equipment
• Set printers and copiers to double-sided
• Track printer and copier usage with
  sustainability software
• Repeat Improve
