7. 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) PC Energy Report
2009 available in
• Half of US employees who use a PC at work typically Information and
don’t shut their computers down at the end of the day. Resources section
• 11% of US employees say they power down their of our web site

17. Business Case for PC Power Management
• Labor costs: ~ $5 / seat
o Identifying appropriate solutions
o Testing & troubleshooting exceptions
o Ensuring that sleeping computers do not interfere with administrative
software updates
• Software costs: ~ $0-15 / seat
o 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
19. 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…
20. 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
21. 5 Ways to Get IT on Board
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
22. 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
23. 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.
