Pollution
4
E-Waste
Technologycreates largeamounts ofwaste, and usedcomputers andelectronics getthrown outwhen they breakor becomeoutdated. 5
• Greenhouse gasses are gasses in theatmosphere that trap and reflect heat andradiation back to the planet's surface.
• Green gasses are contributing to globewarming.

Cause pollutions
• Air, water, heat and noise pollution can all be caused by producing and using technology
Waste
• Manufacturing technology creates large
amounts of waste, and used computers and
electronics get thrown out when they break or
become outdated.
So, how can prevent this!!!Using green computing can prevent
this…
• Cause pollutions
• Produce waste
• Produce green house gases
What is Green computing
• Designing, manufacturing, using and disposing of computers, servers and associated sub systems efficiently an effectively with minimal or no impact on the environment.
Things we can do…
1. Buy energy efficient computers
2. Buy hardware appropriate for the job
For example a 19’’ monitor use 40% more power than a 17’’ monitor.
Things we can do…3. Replace CRT monitor with an LCD monitor.
LCD monitors can use one-half to two thirds theenergy of a CRT monitor, Flat screen monitorsalso result in less eye-strain
Thing we can do…5. Print smarter
Use the electronic print preview to avoid wasted paper.
Print double sides.
Print draft copies when appropriate.
these use less ink and are still readable.
Things we can do…6. Enable power management features on computer
Setting the hibernation or sleep modes to place the computer on low power after a given period of inactivity
Things we can do…7. Recycle old computers
When no longer are able to find a use forcomputer, consider to recycle PC properly.
Things we can do…8. Virtualization
Process of running two or more logical computersystems on one set of physical hardware.
Things we can do…
9. Energy Efficient Coding
Energy efficient coding could reduce the energy
consumption by 25% to 30%.
Improving computational efficiency so that data is processed as quickly as possible and the processor can go into lower power idle state.
• Search-engine site powered by Google Search.
• White consumes 74W whereas black it consumesonly 59W.
Zonbu Computer
• New & energy efficient PC.
• Runs the Linux OS using1.2GH processor & 512MHof RAM.
• Consumes one third of thepower of a typical light bulb.
Sunray Thin Client
• Consume lesselectricity thanconventionaldesktops.
• Consumes 4 to 8watts of power.
ASUS Eee PC• Is one example of an
ultraportable.
• Small Size
• Compact Screen
• Low Cost
• Fairly low-power CPU
• Uses flash memory for storage
Top Green IT Companies1. HP
Programs to reduce GHG and Toxic wastes intheir products and supply chains.
2. Dell
Carbon Neutral, Headquarters
uses 100% Renewable
energy, computer products
use 25% less power (by 2010).
Top green IT Companies
3. Intel
focus is on increasing speed whilereducing energy usage in their products.
4. IBM
Has had formal Environmental policies since1971, and requires all employees to haveenvironmental awareness training.
Top Green IT Companies
5. Toshiba (5.3) Good score on toxics elimination.
6. Apple (5.1) Continues to improve with best score on toxicchemical elimination and e-waste criteria.
7. Sony (5.1)better energy totals.
Top Green IT Companies8. Acer (4.5)Acer is lobbying for stronger chemicallegislation.
9. Lenovo (2.5) Penalty point for indefinite phase out of toxics.
10. Microsoft (2.4) Fails to support strong chemicals legislation.
Conclusion
• Green computing is the scientific study of efficient and effective designing,
manufacturing, using, disposing, and recycling of computers.
• The greenest computer will not amazingly fall from the sky one day, it’ll be the
product of the years of improvements. The features of a green computer of
tomorrow would be like
1. efficiency
2. manufacturing and materials
3. recyclability
4. service model
5. self-powering
6. other trends
• Adopting green computing strategies make sense not only from an
ethical or moral stand-point , but from a commercial stand-point.
• There are many business benefits achievable through the
implementation of a green computing strategy such as cost savings,
disaster recovery and course public relations.
• Green computing is the great requirement to protect environment
and save energy along with operational expenses in today’s
increasingly competitive world.
