Saving Energy in your
the
Office with IT Equipment

Department of Sustainability and Energy Management
Sustainable IT
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
2
– 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)
Sustainable IT
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?

Sustainable IT
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

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 that’s off uses 0 energy
– Plugged in it draws ~2-3 watts for network
connectivity, etc.

POWER MANAGEMENT IS AN EASY WIN
•
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

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
12
Sustainable IT
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
13
Sustainable IT
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

Sustainable IT
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
15
Sustainable IT
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
16
Sustainable IT
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
17
Sustainable IT
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
18
Sustainable IT
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
19
Sustainable IT
12. Start Measuring Things
• Get a Kill a Watt meter
– Test out your peripherals
• Speakers are a surprising sleeper
• Measure ‘Vampire’ energy drains
20
Sustainable IT
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
