3. Objectives
• Understand the green computing concept
• Background of Green Computing
• Why this is important
• Green life Cycle
• Currently available solutions & Technologies
3

4. Introduction
• World is hurry to define the digital era
• What about environment??
• Green computing concept comes to the stage to provide
eco-friendly solutions to this problematic situation.

5. What is Green Computing?
• Also called green IT
• It is an environmental friendly IT where the main
objective is to reduce the harmful materials and maximize
the energy efficiency.
• Reduce the power consumption and thus reduce the
global warming.

6. Why Green Computing?
• Growing of E wastage and Hazardous materials
(Manufacturing computers includes the use of lead,
cadmium, mercury, and other toxics in general. Usually,
computers can contain 4 to 8 pounds of lead alone.)
• Power consumption issues
(3% of the world’s energy consumption.
With the rate of consumption increasingly by 20% a
year, 2030 will be the year when the world‘s energy
consumption will double because of the ICT industry)

7. History
• Energy Star
• Initiated in US Environmental Protection Agency (EPA) and
United States Department of Energy (DoE)
• Sleeping mode
• TCO, Swedish organization launched the TCO
(Tjänstemännens Central Organisation) Certification
program to promote low power consumption CRT monitors
• Business organizations (IBM, Vmware,VIA technologies)
(triple bottom line including society, environment and
economy)

10. Green Use
• Conserve energy
(61 billion kilo watt hours consumption)
(Sleep mode- hibernate mode- power plan)
• Vampire energy
- idle current
- use master control outlet
Myths of power consumption
1. Never turn off computer
2. Turn off and back on is more energy consumption
3. Screen savers save energy
4. Network connections are lost in sleep mode

11. Green Design & Manufacture
• Green design - Designing energy efficient computers,
servers, printers and other digital devices.
• Green manufacturing - minimizing waste during the
manufacturing of computers and other subsystems.
1. Low power hardware
2. Virtualization
11

12. Green disposal
Refurbish and reuse old computers and properly recycle
unwanted computers and other related equipment.
1. Reuse
2. Refurbish & upgrade
3. Recycle
- landfills?
- WEEE (Waster Electrical and Electronic Equipment)
regulation
- Managed to pieces
- Metal recycle
- hazardous smoke and gasses that comes out from these
processes are captured and controlled to release in
environmental friendly manner 12

13. Standards &Regulations
• ENERGY STAR 6.0
- Active from 28th April 2014
• EPEAT (Electronic Product Environmental
Assessment Tool)
• RoHS (Restriction of Hazardous Substances
Directive)
13

14. Summery
• World basis critical topic
• But no attention from developing countries
• This wants to be discussed and proper way of implementation
