Green computing aims to reduce the environmental impact of computing through efficient use of computing resources. It involves designing, manufacturing, using, and disposing of computing devices in a way that is environmentally friendly and sustainable. Approaches to green computing include virtualization, power management, cloud computing, telecommuting, teleconferencing, recycling electronic waste, and consumer awareness. Implementing green computing policies can help conserve energy, reduce costs, and create a more sustainable environment.

2. What is Green Computing?
Green Computing is the efficient use of
computing devices {Resources} in other to
Sustain our Environment.

3. Green Computing should be considered in
•Designing
•Manufacturing
•Usage
•Disposing of this devices(Resources) such
as monitors, printers, storage devices etc.

4. Brief History
The term Green Computing was coined
shortly after the energy Star program in 1992.
Energy Star was lunched by US EPA
Saves 20%- 30% of Energy

5. Electronic Product Environmental
Assessment Tool
• EPEAT helps purchasers identify greener
computers and other electronics
• It is used to evaluate the effect of a product
on the environment
• It ranks products as Gold, Silver, Bronze based on a
set of environmental performance criteria.

6. Why Green Computing ?
• Sustain our Environment
Prevent Climatic Change
Prevent Global Warming
• Prevents health related issues
Caused by materials such as lead, mercury, pvc . Which causes
brain damage, kidney disease, cancer etc.
• Energy Conservation
leaving the computer on when not in use wastes energy
printing hard copies is not always necessary it is often
wasteful
• Save Money

7. Approach to Green Computing
• Virtualization
With virtualization, a system administrator can run
more than one servers on a singles machine
• Power management
HDD versus SSD

9. Cloud computing
• On demand computing
it addresses two major ICT challenges
related to Green computing
 Energy usage
 Resource consumption
P
I
S

10. Telecommuting
• Reduces greenhouse gas emissions related
to transportation
• Increases worker satisfaction
• Reduces costs for office space
• Reduces Heat
• Conserves Energy

11. Teleconferencing

12. Green Disposal Remedies
• Refurbish: Instead of discarding the computing
Device you can upgrading
• Reuse: Donate pc to people/charity
• Recycle….
printer cartridges
paper
batteries may be recycled as well

13. E waste
Electronic waste:
Examples: Computers, LCD / CRT screens, cooling
appliances, mobile phones, etc.,
It also involves
•Recycling
•Consumer awareness
•Processing techniques

15. Remedies for Users
• Turn off the computer when not in use
• Use Products with the Energy Star label
• Don’t print unless necessary.
• Use Voip instead of Traditional phone call
• Use LCDs instead of CRTs as they are more
power efficient.

Green Computing

18. Facts about Green Computing
• for a large institution, say a university of 40,000 students
and faculty, the power bill for just computers can come to
$2 million / year source: prezi.com
• Datacenters generates 0.3 percent of the world's CO2
emissions. Source: Hp care center
• The use of screen savers does not save energy.
• According to the Columbia University Guide to Green
Computing, if the paper used each year for personal
computing were laid end to end, it would circle the Earth
more than 800 times

19. • ICT accounts for 2% global C02 emmisions almost same
as Aviation (source: explainingcomputers.com)
• In the US and UK 20 billion kWh is wasted each year
dues to PCs left on over Night (source national Energy foundation 2006 &2007)
• Energy Efficient Coding could save up to 30% of energy
• Over 130 thousand PC are discarded every day in us
• Over 100 million cell phones every year in us
Source :cnet.com 2013
• Intel Microprosessor is the most energy efficient,
emmission reducing device ever created.
( source intel white paper(2007)}

20. Conclusion
• In conclusion I would say that the government,
educational institution, financial institution,
hospitals, individual and other organization
should set and fully implement Green computing
policies in other to make the world a better place
for you and me by sustaining our environment
