5. The Problem: IT Energy Waste
• Every day 156 million employees in the US, the UK and Germany decide
whether or not to shut down their PCs
• 1.3 million tonnes of unnecessary CO2 was emitted by UK businesses in
2009 by not turning off idle PCs wasting nearly £300 million
• A UK company with 10,000 PCs wastes £168,000 and 828 tonnes of CO2
annually through not shutting down PCs
• 67 percent of UK employees feel that their companies should be doing more
to reduce power consumption
• Only 2 percent of UK employees shut down their PCs at night because they
were directed by their company to do so
• 50 percent of those who use a PC at work typically choose not to shut down
their PC at the end of the day
• PC power costs are the biggest contributory factor to IT costs and can
account for 25 percent of overall building costs

20. Defining PC Power Management
► Actively reducing the energy consumption of operating PCs and monitors
by enabling lower power states during periods of inactivity — where the PC
and monitor are drawing energy but no useful work is being performed
(e.g., nights, weekends, holidays, and workday breaks).

21. Reducing Energy Costs Drives Green IT

22. Reducing Facilities Costs Is a Priority

23. PC Energy Consumption Is Just as Important

o Ensuring that sleeping computers do not interfere
with administrative software updates

PC

27. Hardware Refresh ROI
• Moore’s Law + Design Innovations enable continuous,
relatively rapid improvements in computer energy-efficiency
• As a consequence: “Vintage Does Matter.” Older computers
are highly wasteful of energy and very costly to run, compared
to new models that might replace them – PCs as well as data
center servers
• Power management technology should be used on old and
new computers alike

28. Reducing Your Carbon Footprint
• For every 1,000 PCs your company begins using aggressive
power management, that equates to a savings of £9,000 per
year, plus air conditioning costs.1
• Savings will be even greater if you are currently committed to
carbon neutrality or reduction because you will reduce the
number of carbon offset credits needed by participating in
CSCI.
• Employing aggressive power management on 1,000 PCs can
save approximately 118.26 tons CO2 per year.2
• 1 carbon credit = 1 ton of CO2
• 1 carbon credit costs ~ £11.12
• 118.26 tons X £11.12 ~ £1,315 savings in carbon offset credits
per year
1 Assumes system is powered on 2,000 hours per year (40 hrs/week X 50 weeks)
2Aggressive power management can save 157.62 KW hours per year. 1 KW hour is equivalent to 0.00075 tons CO2.
