IT Energy Waste
The Problem: IT Energy Waste in the US
• Every day 156 million employees in the US, the UK and
Germany decide whether or not to shut down their PCs
• By not shutting down PCs, a US company with 10,000
PCs wastes annually:
• $260,000 annually
• 1,871 tons of CO2 emissions
• 63 percent of US employees feel that their companies
should be doing more to reduce power consumption
• Only 3 percent of US employees shut down their PCs at
night because they were directed by their company to
do so (opportunity here for companies to set policy)
• Half of US employees who use a PC at work typically
don’t shut their computers down at the end of the day.
• 11% of US employees say they power down their
computers to reduce their company’s electricity bill.

Energy Waste: Industry Level
This waste adds up quickly.
• The global information and
communications technology
industry accounts for
approximately 2 percent of
global CO2 emissions1
• Energy costs will be 50 percent
of the average IT budget in just
a few years2
• By 2010, about half of the
Forbes Global 2000 will spend
more on energy than on
hardware3
• There are 1 billion+ PCs
worldwide, projected to be 2.25
billion by 20154

Business Case for PC Power Management
• Labor costs: ~ $5 / seato Identifying appropriate solutions
o Testing & troubleshooting exceptions
o Ensuring that sleeping computers do not interfere with administrative software updates
• Software costs: ~ $0-15 / seato Many solutions are free
o Commercial solutions range from roughly $3-15 per PC
• Vs. energy savings of $40-$160 / seat
Assumptions: 1000 seats; labor costs = 2 weeks of work for one network administrator @ $2,500 per week
Overcoming Barriers: Myths Regarding Power Management
Overcoming Barriers to Adoption
• On surface, implementing power management would
seem simple:
o Many technical options available to allow network
administrators to activate sleep settings quickly and easily
• However, there are obstacles
o Split incentives in large organizations
o Need to articulate clear ROI
o Myths about power management
o Other concerns…
5 Reasons IT or others may not initially
share your enthusiasm for CPM
1. Energy savings aren’t rewarded in IT’s budget
2. Even a free solution will involve IT staff time to
implement
3. CPM could initially complicate how PCs receive
security patches and anti virus updates
4. Urgent new security threats emerge regularly to absorb
any “free time”
5. Already spending nights and weekends on systems
upgrades and other IT initiatives
1. Estimate your potential $ savings
2. Share the savings opportunity with your management
and any “friends” in IT
3. Counter technical objections with “you might be right:
let’s ask an expert”
4. Make one modest request: join a 30 minute call with
CPM tech expert from EPA ENERGY STAR or CSCI
5. Share the glory
5 Ways to Get IT on Board
Common Myths
• MYTH #1: Sleep features can wear out hardware by forcing the
computer to turn on and off several times a day
• MYTH #2: Computers and monitors use more energy with power
management settings activated, due to power surges when cycling
on and off
• MYTH #3: System standby and hibernate features can render a
computer unstable, causing system crashes and/or preventing it
from waking
• MYTH #4: Computer users will complain about having to wait for
their machines to “wake” from system standby or hibernate
1 Source: U.S. EPA ENERGY STAR Low Carbon IT Campaign
Common Myths
• MYTH #5: Sleeping computers will not receive important software
updates such as new antivirus definitions and Windows security
patches
• MYTH #6: Because Microsoft ships Win 7 software with computer power
management settings enabled, there is no need to worry about sleep
settings on Win 7 machines
• MYTH #7: My network administrator says our PCs are “enabled for
hibernate,” so we must already be taking advantage of computer power
management features.
• MYTH #8: You’d actually save more energy – and a lot of trouble – if
you simply required people to turn off their computers each night.

Case Studies
Case Study: National Instruments
The ChallengeIT was getting requests to support internally-built applications from
multiple departments to remotely turn on their computers at night.
Employees wanted to shut down at night to save energy but they
needed/wanted to be able to log-back on from home as needed. 97
percent of desktops and 58 percent of laptops did not have a sleep
timeout set at all. 71 percent of PCs were left on overnight
The SolutionGreen Team employees want to encourage more sustainable
business practices. Implemented solution in conjunction with
CSCI’s Power Management Incentive Program. Will utilize the
Austin rebate of $5 per license and investigate any possible rebates
globally. View the video case study on Climate Savers Computing
Initiative’s web site.
The Benefits•Projected cost savings between 30 – 54 percent
•Projecting savings equivalent to nearly 3 percent of annual energy
usage at headquarters over next 5 years
”As conserving the
world's resources
becomes more
important, National
Instruments has
recognized the need to
reduce its
environmental impact.
NI worked with Climate
Savers Computing… to
implement a pilot
project to reduce
energy consumption by
computers.”
Heidi Baschnagel
Director of Marketing
National Instruments
Case Study: Massachusetts
Dept. of Energy Resources
The ChallengeExecutive Order No. 484, issued April 2007, requires state
agencies to reduce energy consumption and greenhouse gas
emissions in state facilities.
The SolutionThe Commonwealth created Enterprise Desktop Power
Management Standards as an energy strategy to increase energy
conservation and reduce plug-loads through technologies,
operations & behaviors. The standards include:
•Configure workstations to take advantage of available power
management options when provisioned for employees
•Shut down workstations during extended period of non use
The Benefits•Preliminary energy savings of 13 million kWh
•Projected cost savings of $2 million
“Implementation of
power management
options during periods
of inactivity can reduce a
machine’s power
consumption to less
than 6 watts per
workstation, an energy
reduction of some 95%,
and save as much as $60
or more per computer
per year.”

reduce our energy use,
which is good for
business and good for the
planet. This is a wonderful
collaboration between two
members of the Climate
Savers Computing
Initiative to achieve our
mutual goal of reducing
power consumption to
improve the environment.
John Glowacki, Chief
Technology Officer, CSC and
Board Director, CSCI
Case Study: City University of New York
The ChallengeWith 23 institutions and over 400,000 students spread out
across 19 campuses, CUNY is constantly under pressure to
reduce costs. However, environmental leadership has been
a strength of theirs in appealing to new students and
alumnae alike. Combined they afford the University to focus
it’s resources on the highest quality of education delivered.
The SolutionUse of Verdiem’s Surveyor with an innovative program with
the New York Power Authority to effectively manage over
30,000 clients.
The Benefits• $600K annual savings
• 4M metric tons CO2 annual reduction
• Increased visibility, control and management of IT assets
“With the current
technology available, a
project like this is
easier to implement than
many energy conservation
measures, with a faster
payback.“
Art Fasolino,
Chief Engineer
CUNY
Case Study: BC Hydro
The ChallengeBC hydro has vast expertise in energy conservation and had
already invested heavily in IT energy efficiency gains. Their
desktop infrastructure was already very efficient relative to most.
But they knew they could do more!
The SolutionImplemented solution using Faronics Power Save which analyzes
CPU, application activity, disk, keyboard, and mouse status
before taking power management actions and delivers enterprise-
wide desktop computer energy management.
The Benefits•Over 1M KWhrs saved annually
•Greater perceived performance of network by users interviewed
•Enhancements in desktop infrastructure management
•Leveraged experience to utility incentive programs
”2008 will be
remembered as the
year PC Power
Management Came
of Age.”
Dave Rogers,
Technology Advisory
BC Hydro
Case Study: Ford
The ChallengeDifferent regions can have different power costs and
savings. Implementation costs are centralized but power
costs are distributed. Different user types, different regions
means managing profiles will not be easy, start simple
The Solution1E NightWatchman PC Power Management rolled out to
Ford computer users across the U.S. and migrated to Ford
operations around the world later in the year.
The Benefits•The savings on power cost expected to top $1.2 million
annually when the system is fully implemented.
•By reducing PC power consumption, Ford also stands to
reduce its carbon footprint by an estimated 16,000 to 25,000
metric tons annually.
FORD MOTOR
COMPANY
“In the past, as many as
60 percent of Ford’s PC
users haven’t shut their
PCs off at the end of the
business day, resulting in
wasted energy. Going
forward, we’ll be able to
manage PC power
consumption more
efficiently while
minimizing interruptions
during the working day as
a result of software
updates.”
Keith Forte, IT Project
Supervisor, Ford
