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.”

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,

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
