2. What is Green IT?
Green IT refers to
Environmentally
sustainable IT or
computing. It is the
“study of practice
of designing,
manufacturing,
using , and
disposing of
computers, servers
and associated
subsytems”
6. Computer virtualization is the process of running
two or more logical computer systems on one set
of physical hardware.
7. Study by Mckinsey found that among a total
of 32 servers at 4 production datacenters ,
32% were running at or below 3% peak and
average utilization.
Companies can
reap a 65%
reduction in
server count
through
virtualization.
10. PCs with a screensaver going
can use well over
100W of
power , compared with only
about 10W in sleep mode.
Companies can save
between $25 to $75 on
power bills per pc per year
by powering down
machines when not in use
11. Operating system issues
Linux vs. Windows Power Usage
In “desktop usage” power tests ,both Fedora
and Ubuntu had consumed more power than
Microsoft Windows. Fedora and Ubuntu were
consuming 65 Watts while Windows had only
consumed 58 Watts .Granted,this test isn’t
very controlled and was just intended to give a
rough overview.
12.
13. • Desktop computer power supplies(PSUs) are
generally 70–75% efficient, dissipating the
remaining energy as heat.
• An industry initiative called 80 PLUS certifies PSUs
that are atleast 80% efficient; typically these models
are drop-in replacements for older, less efficient
PSUs of the same form factor.
• An 80 Plus power supply can save about 85
per PC,per year.
KWh
15. • Video-conferencing between office and client sites
thereby reducing travel cost and decrease negative
impact on the environment
• If all commuters worked one day a week from their
home,5.85 billion fewer gallons of oil would be
used each year
17. E-mail are considered “green”
because it reduces paper use
when used to distribute
documents electronically,
thus reducing carbon
footprints and cost.
Printing 50% less than before, FICO saved 8
million
$300,000 in
sheets of paper in a year thereby saving
paper, printer maintenance and related print costs.
20. BLACKLE
• Blackle is the search-engine site powered by Google Custom
Search created by Heap Media.
• Blackle came into being based on the concept that when the
computer screen is white,presenting an empty word page or
the Google home page,your computer consumes 74W.
• When the screen is black it consumes only 59W
21.
22. Zonbu Computer
• The Zonbu is a new, very
energy efficient PC
• The Zonbu consumes just
one-third of the power
of a typical light bulb
• The device runs the Linux
operating system using a
1.2 GHz processor
and 512MB of RAM
23. Fit PC
• Fit PC is the size of a paperback
and is absolutely silent,
yet fit enough to run
Windows XP or Linux
• Fit-PC is designed to fit
where standard PC is too bulky,
noisy and power hungry
• Fit-PC only draws 5 watts,
consuming in a day less power than a traditional PC
consumes in 1 hour
24. Steps by Apple
• MacBook keyboards are
made from single
piece of aluminium
• MacBook pro notebooks have long lasting batteries
whereas a normal notebook uses three batteries a
Macbook will use only one through out its life time.
25. Steps by DELL
• Their free world-wide product recycling program
allow users to properly dispose their product safely
• Their “Plant a tree for me” project can offset a
customers carbon emissions for only two dollars.
26. Conclusion
• From the all above
discussion we have
seen that there is high
power consumption by
all this data centers,
computers and other
technical equipments.
• To reduce the power
consumption and make
this all equipments
echo-friendly GREEN Computing
is necessary
