3. What does green computing
means?
 It is the environmentally responsible and eco friendly
use of computer and their resources .
 In broader terms, it is also defined as the study of
1. Green disposal
2. Green design
3. Green use
4. Green manufacture

4. Green
Disposal
 Repurposing and existing computers or
appropriately disposal of , or recycling of unwanted
electronic equipment .

6. Green
Design
 Designing energy – efficient computers , severs ,
printers , projectors and other digital device .

7. Green
Use
 Minimizing the electricity consumption of computers
and their peripheral devices and using them in an
eco-friendly .

8. Green
Manufacture
 Minimizing waste during the manufacturing of
computers and other subsystems to reduce the
environmental impact of these activities.

10. Things We Can Do
Buy energy efficient
computers.
Replace a CTR monitor
with an LCD monitor.
Recycle your old
computer.

11. Objectives of Green
computing
To gain an understanding why the green
computing is instrumental for the
environment.
To identify key issues relevant to green
computing and evaluate different approaches
to these problems.
To make use of computers as energy – efficient
and design algorithms and system for
efficiency –related computer technologies.

12. Five Steps of Green
Computing
Develop a
sustainable
green computing
plan.
Recycle
Make
environmentally
sound purchase
decisions.
Reduce paper
consumption.
Conserve energy.

14. How To Go Green
 Turn off the computer when not in use even if just for an
hour.
 Use power saver mode.
 Use hardware and software with energy star label.
 Don’t print unless necessary or you are ready.
 Consider a smaller monitor a 14 inch display uses 40%
less energy than a 17 inch one.
 Enable stand by/sleep mode.
 Switching from a locally hosted email to cloud based
email systems.

15. Example of Green Computing:
 THIN CLIENT :
It is a computer or a computer program which depends
heavily on some computer to fulfill its traditional
computational roles.
