THE BIG PICTURE: IT & CO2 EMISSIONS

• IT Industry Energy Usage– Datacenters use 3% of the total energy used in the 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 – 50 million tons of e-waste produced yearly worldwide

• User Behavior – As many as 60% don’t turn computer off at night– US, with 5% world population, uses 30% of world’s paper – Typical office disposes 350 tones waste paper/employee/year!

IT AT ABC PTY LTD / or SCHOOL ABC!

• Faculty, staff and students– 20 desktop/laptop computers– 2 servers

• 50% of energy use from IT infrastructure!• Number of computers growing 5% per year• Need to keep energy usage flat, or reduce, while

increasing productive output of IT infrastructure

So what can you do?

1. BUY WITH SUSTAINABILITY IN MIND

• Buy only what you need– High-end graphics cards can use as much energy as CPU

• 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 (VERY IMPORTANT!)

2. 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!!!

• 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

3. OPTIMIZE PERFORMANCE

• If it’s running slow, it’s wasting energy– 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

4. 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

5.PRINTING

• The Obvious Stuff:– Set your print drivers to default to 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 is available!– 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!!!!!

• Track printer/copier sustainability with network tool– Most vendors have a multi-vendor tool

• Xerox’s Sustainability Calculator, HP Webjet Admin

6. 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

7. KEEPING IT DIGITAL

• Faxes– Scan and email docs rather then fax them– Get a Fax Server

• Receive and send faxes via email

8. 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

9. Start Measuring Things

• Get a Kill a Watt meter– Test out your peripherals

• Speakers are a surprising sleeper

• Measure ‘Vampire’ energy drains

10. 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

12. What Is Sustainable Computing?

Sustainable Computing is a principle that embraces a range of

policies, procedures, programs, and attitudes that run the length and breadth of any use of information technologies. It is a holistic approach that stretches from power to waste to purchasing to education and is a life-cycle management approach to the deployment of IT across an organization. The

concept of Sustainable Computing considers total cost of ownership, the total environmental impact, and the total benefit of technology systems

13. Areas of Focus (Goals)

• Power = Energy Conservation!

• Waste = Have a recycling program!

• Purchasing = will purchase only Energy Star or EPEAT registered products - including peripherals as they become available.

• Thin Client Pilot = In addition to the business benefits, this system can reduce the overall environmental footprint of a desktop by as much as 75% (Source: Sun Microsystems: Sustainable Computing).

• Education = having Poster campaign, periodic email

reminders, web site, Sustainable Computing Guide!20

Little things you can do to make a big difference!

• the biggest thing is turning off all equipment when you leave for the day – computers, monitors, copiers, printers, fax machines, etc.

• Print in Economode when you can – this saves toner by printing lighter on paper

• Print duplex – this saves paper

• Buy refurbished ink cartridges and toner when possible
