This document discusses green computing, which refers to environmentally sustainable and responsible practices related to computing. It aims to minimize computing's environmental impact through efficient and effective design, manufacturing, use and disposal of computers and related systems. Specific green computing strategies discussed include reducing energy consumption through practices like turning off computers when not in use, using power saver modes, and using more efficient LCD monitors instead of older CRT monitors. The document also covers a brief history of green computing and initiatives like Energy Star, as well as advantages like energy savings and being environmentally friendly.

3. INTRODUCTION
 Green computer is the environmentally responsible use of
computer and related resources.
 It is the study and practice of designing, manufacturing, using
and disposing of computers, servers and associated
subsystems efficiently and effectively with minimal or no
impact on the environment.

4. Green Computing
 Why?
computer energy is often wasteful
leaving the computer on when not in use (CPU and fan consume power, screen savers
consume power)
printing is often wasteful
how many of you print out your emails or meeting agendas
printing out partial drafts
for a “paperless” society, we tend to use more paper today than before computer-
prevalence
pollution
manufacturing techniques
packaging
disposal of computers and components
toxicity
as we will see, there are toxic chemicals used in the manufacturing of computers and
components which can enter the food chain and water!

5. Reducing Energy Consumption
 Turn off the computer when not in use, even if just for an hour
 Turn off the monitor when not in use (as opposed to running a screen
saver)
 Use power saver mode
 Use hardware/software with the Energy Star label
 Don’t print unless necessary and you are ready
 Use LCDs instead of CRTs as they are more power efficient

6. Energy Use of PCs
 CPU uses 120 Watts
 CRT uses 150 Watts
8 hours of usage, 5 days a week = 562 KWatts
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
 Energy use comes from
electrical current to run the CPU, motherboard, memory
running the fan and spinning the disk(s)
monitor (CRTs consume more power than any other computer
component)
printers

7. HISTORY
 It originated in 1992 at the U.S Environmental protection
Agency that lunched Energy Star Program.
 Shortly After That the term “green computing” was coined.
 After that the Swedish also lunched the TCO Certification.

8. Refers to
environmentally
sustainable
computing
New Paradigm
of designing the
Computer systems
Which considers
Processing
Performance
&
also the energy
efficiency
The study and practice of designing, manufacturing, using,
and disposing of computers, servers, and associated subsystems
such as monitors, printers, storage devices, and
networking communications Systems efficiently and effectively
with minimal or no impact on the environment.

9. ADVANTAGE
 Energy Saving
 Environmentally Friendly
 Save more money per year
 Can give you a tax right off

10. DISADVANTAGE
 High Startup Cost.
 Not Readily Available.
 Still in Experimental stage.
 Sacrifice Performance For Battery Life.

11. FUTURE SCOPE
The plan towards the green computing includes the
usage of such electronics products and services with the
optimum efficiency and all possible option towards
energy savings. The companies nowadays are looking
forward to implement the Eco-friendly components in
computers, the use of sustainable components will
become the norm rather than exception in future.

12. Some Recent Implementations of ‘Green
Computing’
 Blackle
 Zonbu Computer
 Fit-PC
 Sun Ray Thin Client
 Asus Eee PC

13. CONCLUSION
 The beauty of pursuing a green computing strategy is its
multifaceted benefits.
 Green computing is not about going out and designing
biodegradable packaging for products.
 Now the time came to think about the efficiently use of
computers and the resources which are non renewable.
 It opens a new window for the new entrepreneur for harvesting
with E-waste material and scrap computers.
