This presentation discusses green computing, which refers to environmentally sustainable and efficient computing practices. The objectives of green computing are to minimize energy consumption, purchase green energy, reduce paper/consumable use, and minimize equipment disposal requirements. Computing harms the environment through increased energy/cooling needs for data centers and the hazardous materials in devices. Green computing aims to address this through green use, green disposal, green design, and green manufacturing. Benefits include reduced energy consumption and waste, while drawbacks include potential costs and performance sacrifices. Major organizations promoting green computing are The Green Grid and the EPA's Energy Star program.
3. The study and practice of designing,
manufacturing, using, and disposing of
computers, servers, and associated
subsystems—such as monitors, printers,
storage devices, efficiently and
effectively with minimal or no impact
on environment.
GREEN COMPUTING
4. Core objective of green computing:
1.Minimizing energy consumption
2.Purchasing green energy
3.Reducing the paper and other consumable used
4.Minimizing equipment disposal requirements
5. WHY GO FOR GREEN COMPUTING ????
Today main problem of the world is ”GLOBAL
WARMING”.
The atmosphere is becoming hot and causing
many problems to living organisms.
Computers also plays a major role in polluting
world.
6. HOW COMPUTING HARM
ENVIRONMENT ?
Increase in power ,cooling and space for data centre
2007-$4.5 BILLION OF ELECTRICITY
2011-$7.4 BILLION OF ELECTRICITY
2011- DOUBLE CO2 OUTPUT
61 billion kilowatt-hours of electricity, at an estimated
cost of $4.5B annually.
7. Various Hazardous materials are present inside
computer which indirectly harm human body
These are:
A. Cadmium and Sulphur (damage your kidney,lever damage ,heart
damage & eye irritation).
B. Mercury (neurological damage,memory loss,muscles weakness)
.
C. Lead (disrupt brain neurotransmitters)
8. Four path along which we believes the environmental
effects of computing should be addressed:
1. Green Use: Reducing the energy consumption of computers and other
information systems as well as using them in an environmentally sound
manner
2. Green Disposal: Refurbishing and reusing old computers and recycling
unwanted computers and other electronic equipment
9. 3. Green Design: Designing energy efficient and environmentally
sound components, computers, servers and cooling equipments.
4. Green Manufacturing: Manufacturing electronic components,
computers and other associated sub systems with minimal impact or
no impact on the environment.
11. Average computer users can employ the following general tactics to
make their computing usage more green:
1. Use the sleep mode when away from a
computer
2. Use flat-screen or LCD monitors.
3. Buy energy efficient notebook computer.
4. Activate the power management features
5. Make proper arrangements .
6. Turn off computers at the end of each day
7. Refill printer cartridges, rather than buying
new ones
8. Instead of purchasing a new computer,
try refurbishing an existing device.

13. TURNING OLD COMPUTER PART TO GREEN :
• Glass monitor
• Keyboard
• CD Rom drive
• Plastic case
• Cathode ray tube (CRT)
• Cables
• Copper in power cord
• Metal from circuit board
• Printer cartridges
• Batteries

15. NEED OF GREEN COMPUTING
It is observed that most of the data centers don’t have sufficient cooling
capacities. This results in environment pollution
Another effect is because of toxicity. There are toxic chemicals used in the
manufacturing of computers and components which can enter the food chain
and water.
“Data centre emit over 150 metric tons of CO2 per year, and the volume is
increasing rapidly.
16. Many technology companies actually belong several of these to further
there goals of becoming more “green”.
Some of these green organizations are:
1. “The Green Grid is a global consortium of IT companies and
professionals seeking to improve energy efficiency .The Green Grid
include AMD, EMC, Intel, APC, HP, Microsoft, Dell,oracle.
2.The U.S. Environmental Agency is a government agency that was
created to protect human health and to safeguard the natural
environment. This agency also created a joint program called Energy
Star with the U.S.
“The ENERGY STAR label was established to: Reduce
greenhouse gas emissions and other pollutants caused by the
inefficient use of energy
17.
18.
19. 1.Reduce energy consumption of computing resources
2. Save energy during idle operation
3.Use eco-friendly sources of energy
4. Reduce harmful effects of computing
resources
5. Reduce computing wastes
ADVANTAGES
20. 1.Green computing could actually be quite costly.
2.Sacrifice performance for battery life.
3.Still in experimental stages.
4. Not for everyone.
DISADVANTAGES
21. It has taken upon itself the goal to provide
society‘s needs in ways that do not damage or
deplete natural resources. Mainly this means
creating fully recyclable products, reducing
pollution, proposing alternative technologies in
various fields, and creating a center of
economic activity around technologies that
benefit the environment.
