3. Overview of Green Concept
Environment in Present Days:
Air pollution, Water pollution, Land pollution
Green Computing

4. Overview of Green Concept Cont.’s
Global warming :
Ice cap at the North Pole continues to shrink!
Green Computing

5. Overview of Green Concept Cont.’s
Electronic wastes :
In the U.S. alone, 500 million obsolete computers, and 130 million cell phones are thrown out every year.
Green Computing

6. Why Green, Not Yellow or Red?
G enerate less waste
r ecycle everything that cannot be reused
e ducate the community on eco-friendly options
e valuate the environmental impact of actions
n ourish discussions and activities that integrate environmental education into existing curriculum
Green Computing

7. Green IT Green IT refers to environmentally sound IT
the study and practice of designing, manufacturing, disposing of computers, and associated subsystems efficiently and effectively with minimal or no impact on the environment
Green Computing

8. Green IT Cont.’s
Green IT spans a number of focus areas and activities, including:
design for environmental sustainability
energy-efficient computing
power management
data center design, layout, and location
server virtualization
Green Computing

9. Green IT Cont.’s responsible disposal and recycling
regulatory compliance
green metrics, assessment tools, and methodology
environment-related risk mitigation
use of renewable energy sources; and
eco-labelling of IT products
Green Computing

10. IT’s Environmental Impact
Electronic devices consume electricity - this then increases carbon dioxide emissions
Waste - Manufacturing technology creates large amounts of waste, and used computers and electronics
Health hazards - Using toxic materials that can harm our health can cause cancer e.g lead, cadmium and mercury
Green Computing

11. IT’s Environmental Impact Cont.’s
Pollution - Air, water, heat and noise pollution can all be caused by producing and using technology
Green Computing

12. A Holistic Approach to Green IT
Virtualisation
Power Management
Green IT
Greening Data Centers
Material Recycling
Green Computing

13. Virtualisation
The process of running two or more logical The process of running two or more logical computer systems on one set of hardware
Applications e.g. VMware (ESX Server), Citrix (Xen) and Microsoft (Hyper-V).
Green Computing

14. Virtualization Benefit
Virtualization helps a company / enterprise lower power and cooling consumption, by reducing the number of machines and servers it needs.
Virtualization on platforms can run across hundreds of interconnected physical computers and storage devices, to create an entire virtual infrastructure thus eliminating huge energy consumption in data centers
Green Computing

15. Power Management
IBM, Hewlett Packard, SprayCool, and Cooligy are working on technologies such as liquid cooling, nano fluid cooling systems, and in-server, in-rack, and in-row cooling
new high-density servers, using hydrogen fuel cells as alternative green power sources
Power Stacking HP Blade Chassis
Green Computing

16. Material Recycle
Green disposal. Refurbish and reuse old computers and properly recycle unwanted computers and other electronic equipment
Donate all equipment's if not of use
Used appropriate recycling agents to recycle
Green Computing

17. Greening Data Center
use a synthetic white rubber roof, paint, and carpet that contain a low volatile organic compound (VOC)
make use of natural light as well as green power electricity generated from solar or wind energy—to run the data center
investing in energy management software to regulate power usage
Green Computing

18. Benefits of greening IT
decreases waste and can offer potential cost savings to organizations that reuse IT assets
Reducing carbon and other GHG emissions
Reducing energy and running costs
Reducing the amount of space need for servers
Green Computing

19. Benefits of greening IT Cont.’s
Green Computing

20. Green IT Standards and Regulations
Epeat
assists buyers to evaluate, compare, and select desktop computers, notebooks, and monitors based
on their environmental attributes
Energy Star 4.0 Standard
The new Energy Star 4.0 standard regulates energy
performance of external and internal power supplies
Green Computing

21. Green IT Standards and Regulations Cont.’s
RoHS Directive
The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive
aims to restrict the use of certain hazardous substances e.g. lead, cadmium, mercury, hexavalent chromium, or flame retardants
Green Computing
