This document summarizes a seminar presentation on green computing. It discusses how green computing aims to design, manufacture, and dispose of computing devices in an energy-efficient and environmentally-friendly way. Some key points discussed include the history of green computing initiatives like Energy Star labeling; approaches like virtualization, using screensavers, and recycling electronics; and advantages like energy savings but also challenges like higher costs. The presentation provides examples of how approaches like virtualization and using dark screens instead of screensavers can significantly reduce energy usage.

Guided by:
• Prof. M. Laddha
• Department of
Computer
Engineering.

3. AGENDA:

5. Green Computing:
It is the study of designing,
manufacturing, using & disposing the
computing devices in such a way that
it consumes less energy & it is safe for
the environment.
ECOFRIENDLY use of
computers and their
resources

6. • It is also known as Green IT
• Energy efficient and environmentally
friendly technology

7. HISTORY
EPA: Environmental Protection Agency
DOE: Department Of Energy

8. • In 1992, The U.S. Environmental
Protection Agency and Department of
Energy launched “Energy Star”
labelling.
• Computing devices which
consumes 20-30% less
electricity than normal devices
to do same work were labelled
with Energy Star.

9. In 2001, Indian agency Bureau of
Energy Efficiency developed program
to efficient use of energy.
The more number of stars the
more energy efficient the device
is.

10. 1. Environmental awareness
2. Social responsibility
3. Reducing impacts on
human health
4. Reducing impacts on
environment

11. • GREEN USE
• GREEN DISPOSAL
• GREEN DESIGN
• GREEN MANUFACTURING

12. • Use sleep and hibernate mode.
• Turn off the computer when not in
use.
• Say no to screen savers.
• Use Energy Star labelled devices.
• Don’t print unless necessary.
• Use LCDs instead of CRTs as they
consume less energy.

14. ADVANTAGES:
• Energy saving.
• Environmentally
friendly.
• Save more money per
year.
• Cost effective.

15. DISADVANTAGES:
• High start-up cost.
• Not readily available.
• Still in experimental
stages.
• Not reached to
everyone yet.
• Scarifies performances
for battery life.

16. • VIRTUALIZATION
• USE OF BLACKLE
• ZONBU COMPUTERS
• FIT PC

17. Virtualization
• Duplicating hardware with
software.
• Computer virtualization is the
use of one set of hardware for
running two or more logical
computer systems.
• Desktop virtualization is also
known as THIN CLIENT.

18. Effects of VIRTUALIZATION:
• No of servers.
• 50-70% of energy saved.
• LOS ALMOS NATIONAL
LABORATORIES:
100 servers converted to 13.
saving of $1.5 million dollars.

20. Use of BLACKLE
• Black GOOGLE
• Save 15 W-hour energy
• White screen 74 Watts
• Black screen 59 Watts
• 750 MW/year energy
saved.

21. • Energy efficient PC
• Consumes 1/3rd of the
power of a typical light
bulb
• The device runs the linux
operating system using
1.2 GHz processor and
512MB of ram

22. • Runs on Windows XP,
Windows 7, Linux
• Silent
• Small in size
• Consumes 5Watts per
day

24. • Concerning speed and price, we are dealing
with the normal PCs which results into high
consumption of energy and cause to
increase in pollution.
• If Green computers are able to gain the
speed near about to the normal PCs and if
they are available then we must use these
PCs to save the ENVIRONMENT.
