1. Green Computing

2. Green: The new color in
Information Technology

3. Green Computing Definition
•The study and practice of
–Designing,
–Manufacturing,
–Using, and
–Disposing of computers, servers, and
associated subsystems—such as monitors,
printers, storage devices, and networking and
communications systems — efficiently and
effectively with minimal or no impact on the
environment.

4. CONT…
•Green Design Strategy?
•Green Manufacturing Strategy?
•Green Use Strategy?
•Green Disposal Strategy?

5. Core Principles of Green Computing
•REDUCE,
•REUSE, AND
•RECYCLE;

6. Profiling Energy Usage For Efficient
Consumption
•What is Energy Usage Profile (EUP)?
•A simple Experiment
– A Simple Fluorescent bulb (60W)
– 1 Hour consumption: 0.06 kWh
– Cost
•$0.0897 per kWh
•$0.0054 per hour
•$47.15 for a year
–CO2 expulsion
•23 lbs for 1 kWh
•1208 lbs for a year

7. EUP for Hardware
• Server consumption
- 383.75W in Idle
- 454.39W in Stress
• $301.54 per year
• 7731.8 lbs of CO2

10. EUP for Applications
• A three server application
• 354W consumption in idle
• $226.67 annual cost
• Example – Simple
write operation

13. EUP for Operating
Systems
• Virtualization helps to reclaim(recover) about 20%
of the peak energy consumption
• Optimization is the key
• Disable unneeded services – Screen savers
• Minimize disk activity – Fixed virtual disk size

14. Approaches to GREEN COMPUTING
•Algorithmic Efficiency
•Power Management
•Video Card
•Display
•Materials Recycling
•Telecommuting

15. Problems and causes with
computers on global warming
1.
     
Leaving the computer when in not use..
(Screen savers, CPU, Fan consumes more power)
2.
     
Printing
  is often wasteful
We are used to printout our works.
3.
     
Pollution via electronics
Manufacturing techniques
Packaging
Disposals of computer parts or any-
electronic item part.
.

16. Problems and causes with computers on
global warming(Cont…)
4.
   
 
  Toxicity (
Lead, Chromium, Cadmium and Mercury)
There are many toxic materials used in computers. But two
materials are very toxic.
Problems:
•
     
Cause damage to nervous system , blood system ,
kidneys, and also cause negative effects on child brain
development
•
     
Also has toxic effects on plants, animals and
microorganisms .
•
     
can cause chronic brain damage

17. Solutions
•Keep PCs
  turned off
, when not in use.
 

Disable screen saver.
 Don’t print until
  it is necessary.
 

Use LCDs
  instead of CRTs
as they are more
power efficient
Use hardware/software
  with
“energy star” label.
It is the “seal of approval” by Energy Star Organization of the
government.
Set low power “Sleep” mode.
-can still download and perform-
other routines.

18. Solutions(Cont…)
Stand By
-it is energy conserving b/c switches to a “low power state.”
 

Hibernate
-It writes an image of what you are currently working on your
file/hard drive and then shuts your PC almost completely off.
Use Email to reduce paper work
Add: “*Please Consider the environment: Do U
really need to print this mail?*”
 
          
(put entire message in Subject line.)

19. Solutions(Cont…)
Place Information web-page, wikis instead of making paper
copies.
(online resource consume 90% less energy and produce
85% fewer co2 emissions.)
 

Recycling E-waste:
 Developed countries have now facility of recycling e-waste.

20. Research Reports for email
•A study by a physicist at Harvard, estimated
that the average Google search released 7
grams of carbon dioxide (CO ).
₂
•However, Google disputes this figure,
arguing instead that a typical search
produces only 0.2 grams of CO
₂
.
•0.3g
 
CO2e: A spam email
4g
 
CO2e: A proper email
 
50g
 
CO2e: An email with long and
tiresome attachment

21. Evolution of ‘Green’ Concept
•Energy Star : In 1992, the
 
U.S. Environmental
Protection Agency
 
launched
 
Energy Star,
•Its a voluntary labeling program that is designed to
promote and recognize energy-efficiency in monitors,
climate control equipment, and other technologies.
•Swedish organization TCO Development: Concurrently,
the Swedish organization TCO Development launched
the
 
TCO Certification
 program to promote low magnetic
and electrical emissions from
 
CRT-based 
computer
displays;
•This program was later expanded to include criteria on
1)energy consumption,
 2)
ergonomics, and the 3)use
of hazardous materials in construction.

25. To summarize
• Green computing is a novel and an innovative
trend in the world of computing which has
minimum or no impact on the environment.
• Green computing has introduced a range of
equipments and technologies which help in
limiting the impact on the environment.
• Use of EUPs help in different aspects of the
computing world help in recognizing the areas
for improvement.
