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

Green Computing should be considered in

•Designing •Manufacturing•Usage •Disposing of this devices(Resources) such

as monitors, printers, storage devices etc.

Brief HistoryThe 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

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.

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 Conservationleaving the computer on when not in use wastes energy

printing hard copies is not always necessary it is often wasteful

• Save Money

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

Cloud computing• On demand computing it addresses two major ICT challenges

related to Green computing Energy usage Resource consumption

PIS

Telecommuting• Reduces greenhouse gas emissions related

to transportation• Increases worker satisfaction• Reduces costs for office space • Reduces Heat• Conserves Energy

Green Disposal Remedies• Refurbish: Instead of discarding the computing

Device you can upgrading

• Reuse: Donate pc to people/charity

• Recycle….printer cartridgespaper batteries may be recycled as well

E waste Electronic waste: Examples: Computers, LCD / CRT screens, cooling appliances, mobile phones, etc.,

It also involves•Recycling•Consumer awareness•Processing techniques

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.

Some Companies implementing Green Computing

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

• 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

• Intel Microprosessor is the most energy efficient, emmission reducing device ever created.

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
