Do you Know ???

Computers have a negative impact to our environment

Cause pollutions

• and computer monitors are responsible for the unnecessary production of millions of tons of greenhouse gases every year.

Pollution

4

E-Waste

Technologycreates largeamounts ofwaste, and usedcomputers andelectronics getthrown outwhen they breakor becomeoutdated. 5

Produce green house gases

6

• Greenhouse gasses are gasses in theatmosphere that trap and reflect heat andradiation back to the planet's surface.

• Green gasses are contributing to globewarming.

7

Cause pollutions

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become outdated.

Produce green house gases

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.

Paths to Green computing

Green use

Green DisposalGreen design

Green Manufacture

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

Things we can do…4. Turn off computer when it will not be using for several hours.

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.

Green Web Surfing

• 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.

FIT-PC

• Size of a paperback& Silent, runWindowsXP or Linux.

• Draws only 5 Wattsthan PC.

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.
