4. What is Green Computing?
Designing
Manufacturing
Using
Disposing
Recycling
Green computing is the
environmentally responsible
and eco-friendly use of
computers and their
resources.
It is also called as Green IT.
5. Aims of Green IT
• Reducing the use of
environmentally
hazardous materials
like CFCs, lead and
others
• Promoting the use of
recyclable materials
and minimizing use of
non-biodegradable
• Promoting practices
such as energy cost
accounting,
virtualization, eWaste
recycling
• Applications of
technology with
change in lifestyle
habits aimed at
energy conservation
7. Energy Star
• Energy Star is an international
standard for energy efficient
consumer products originated in the
United States of America.
• It was created in 1992 by the
Environmental Protection Agency
and the Department of Energy.
• The Energy Star program was
developed by John S. Hoffman,
inventor of the Green Programs at
EPA.
8. Impacts of Energy Star
• The biggest impact of the Energy Star
rating is manufacturers introducing the
“Sleep mode” in computers to attain a
higher rating.
9. Energy Saved in
Sleep Mode
• Sleep mode places
the consumer's
electronic equipment
on standby when no
user activity takes
place during the pre-
set time.
• Sleeping Monitors
and turned off
monitors can use 0-15
watts.
10. 1997 Kyoto Protocol
• The Kyoto Protocol to the United Nations Framework
Convention on Climate Change (UNFCCC) is an international
treaty that sets binding obligations on industrialized countries
to reduce emissions of greenhouse gases.
• A landmark event in the history of green technology is the
1997 Kyoto Protocol for the United Nations Framework
Convention on Climate Change. This protocol mandates
reducing carbon emissions.
• The Kyoto Protocol made computer manufacturers undertake
energy audits to calculate the electricity used by the device
over its lifetime and determine the quantum of carbon
dioxide emissions to take remedial action.
11. Carbon Emission
• US 23%
• China 16%
• Russia 6%
• Japan 5%
• Germany 3%
• UK 2%
12. How Much Electricity Does a Computer Use?
The Average Home User
• Typical computers use 60-
500 watts
• A computer will use an
additional 35-150 watts
of electricity with a LCD
or CRT monitor.
• Technically this is 95-650
watts of power on a
typical computer being
used.
How to go Green
• Don't use a screensaver
• Screensavers use the
same electricity as a
computer being used,
screensaver uses both
the GPU and CPU on your
computer
• Allowing your computer
to sleep and hibernate
14. ePaper Applications and Advantages to Using
Electronic Paper Technology
• Electronic paper is also known as e-paper and
is a technology designed to imitate the look
and style of ordinary ink and paper.
• E-paper reflects light just as ordinary paper
does, unlike the usual flat-panel display that
is lit with a backlight to illuminate pixels.
• Electronic paper was first developed in the
1970s by Nick Sheri don at Xerox's Palo Alto
Research Centre.
15. Applications of
ePaper
• eBook readers
• Electronic price tags
used in retail outlets
• Bus/Train Station
timetables
• Electronic billboards
16. Advantages of ePaper
– Inexpensive to manufacture
– Uses low energy
– It's portable
– The technology is reusable and can be written over
– Information to be displayed is downloaded through a
connection to a computer or a cell phone.
17. Cloud Computing
• Cloud computing is a type of computing
that relies on sharing computing
resources rather than having local servers
or personal devices to handle applications.
• As a pay-per-use model for enabling on-
demand access to reliable and
configurable resources that can be quickly
provisioned and released
18. Cloud
Characteristics
1. Quickly allot and
relieve resources
whenever required
by clients.
2. Real time back-up
3. Cater to the needs
of clients without
having involve
client into
management
19. Cloud Storage
Advantages
• Pay only for actual used
storage
• Don't need to install
physical storage devices in
buildings
• Backing up, managing of
servers and fixing problems
are also offloaded to the
service provider
• Energy is saved during peak
operating times
Disadvantages
• security of data is not as
good as using fixed or local
servers
• Performance may not be as
good as using a fixed or
local server when the cloud
becomes busy
• There may be certain laws
or policies in your country
requiring the use of
localized servers if the data
is sensitive
20. Green Computing in Western World
Massachusetts Green Computing
Center
• MGHPCC is a joint venture of
University of Massachusetts
• Research programs are being
offered there
The Berkeley Ecology Center
• A community start-up in San
Francisco
• Educate individuals and
businesses on the waste issues
21. Green Computing in Pakistan
• Pakistan possesses vast potential in wind,
micro hydel and hydel power generation
• Government initiatives, it did set up an
institution in 2002 called the Alternative
Energy Development Board (AEDB)
• Country has a total potential of 35,000
MW, which it can produce from wind
power
22. NUST
• NUST College of EME is
holding events and
National Green Energy
Symposium conference
with a mission to educate
the masses about the
concept of the Greener
Planet
Agriculture University
• Started program Energy
Systems Engineering for
the first time in Pakistan
23. Government of the
Punjab Initiatives
Government of the
Punjab initiatives
regarding Green
Pakistan has
distributed Solar
Panels to the Students
in UJALA Program
24. Using Alternative and Eco-Friendly Materials
to Make Computers
• Bamboo- Is becoming
increasingly popular for
making casings for
computers
• Recyclable plastics- One
way is to use
recyclable polycarbonate
resin
25. Eco-Friendly Materials
• Eco-friendly flame
retardant-Flame
retardants are often
some of the most
toxic chemicals in
traditional PCs, there
are flame retardant
silicone compounds
available that are
flame retardant and
completely non-toxic
• The SHC1030D is easy on
the environment too – it's
made from eco-friendly
materials, and is 100%
free of potentially
harmful brominated
flame retardants
26. Green IT Barriers and Benefits
Barriers
• Initial (capital) costs
• Challenge of reengineering
processes and business
practices; revising
procedures
• Reluctance to change-
Cultural and behavioral
• Lack of management, drive
and support
• Lack of motivation among
stakeholders
• Fear of loss of job or need
for retraining
Benefits
• Reduction in power and
resource consumption
• Better resource utilization
• Improved operational
efficiency
• Reduced environmental
impact and carbon footprint
• Total (operational) cost
savings
• Meeting sustainability
demands of customers and
employees
27. How to promote Green IT
• Green Use: Minimizing the electricity consumption of
computers and their peripheral devices and using them in an
eco-friendly manner
• Green Disposal: Re-making an existing computer or
appropriately disposing of, or recycling, unwanted electronic
equipment
• Green Design: Designing energy-efficient computers, servers,
printers, projectors and other digital devices.
• Green Manufacturing: Minimizing waste during the
manufacturing of computers and other subsystems to reduce
the environmental impact of these activities
28. Conclusion
• Power-down the CPU and all peripherals
during extended periods of inactivity.
• Try to do computer-related tasks during
contiguous, intensive blocks of time,
leaving hardware off at other times.
• Power-up and power-down energy-intensive
peripherals such as laser printer s according
to need.
• Use liquid-crystal-display (LCD) monitors
rather than cathode-ray-tube (CRT) monitors.
29. Conclusion
• Use notebook computers rather than desktop
computer s whenever possible.
• Use the power-management features to turn off
hard drive s and displays after several minutes of
inactivity.
• Minimize the use of paper and properly recycle
waste paper.
• Dispose of e-waste according to federal, state and
local regulations.
• Employ alternative energy sources for computing
workstations, servers, networks and data centers.
30. Conclusion
• To build a greener
environment, we must
modify or end many old
and familiar ways of
doing things and discover
new methods.
