This document discusses green computing and outlines ways to make computing more environmentally sustainable. Green computing involves designing, using, and disposing of technology efficiently to minimize environmental impact. It recommends approaches like product longevity through upgradability, efficient data center design with smart cooling and power systems, power management features, recycling electronics waste, and telecommuting to reduce overhead costs and energy usage. Going green through these practices benefits the environment through sustainability and energy efficiency while also saving money and allowing better asset disposal.

1. Green Computing
Go Green, Think Green

2. What is Green
Computing?

3. “Green computing, Green IT, Green ICT or ICT
sustainability, is the study and practice of environmentally
sustainable computing or IT”
It include "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. Why
Green Computing?

5. #1. Do you Know
How To Recycle It?

6. #2. Energy
Consumption and
Rising Prices

7. #3. Where is
Oxygen?

10. And…..

11. Two Costly
Computer Myths

12. Myth -You should never turn off
your computer.
Fact - When you
turn your
computer off, you
not only lower
heat stress on
computer, but also
reduce energy use.

13. Myth - Screen savers save energy.
Fact - Screen savers were originally designed
to help prolong the life of monochrome
monitors. If you want to save energy then kill
your screen saver.

14. Approaches

15. #1. Product Longevity
Look for product
longevity, including
upgradability and
modularity.

16. #2. Data Center Design
Cooling systems
Air management
Electrical systems
Environmental conditions
Information technology (IT) systems

17. #4. Power Management

18. Data center power can be reduced
by storage consolidation and
virtualization.

19. Always Use PC Power Management
Feature in Operating System

20. Always
use 80 Plus
Certified
Power
Supply
Units

21. Select a Video Card based on low idle
power, average wattage or performance
per watt.

22. With LED, Go Green

23. #5. Materials Recycling
Submit e-waste to municipal or private
recycling centers to salvage & recycle or
donate to charities or non-profits

24. #6. Telecommuting
Use Telecommuting for hassle free
Communication with lower overhead costs,
office space, heat and lighting

25. #7. Always use Energy Star–
compliant computer Appliances.

26. To Sum Up…
Green Use
Green Design
Green Disposal
Green Manufacturing
