4. What Is Green Computing?
"The study and practice of designing,
manufacturing, using, and disposing of
computers, servers, and associated
subsystems efficiently and effectively with
minimal or no impact on the environment."

5. Why Green Computing?
 Growing public environmental
awareness
 Increasing impacts on environmental
and human health
 Corporate social responsibility

6. About Green Computing
• Origin
• Regulations And Industry Initiative
1.Government
2. Industry

7. Roads To Green Computing
• Green Use
• Green Disposal
• Green Design
• Green Manufacturing

8. Approaches
• Virtualisation
• Algorithm Efficiency
• Power Management
• Power Supply
• Display
• Storage
• Material Recycling
• Telecommunicating

9. VIA Technologies
• Carbon Free Computing
• Solar Computing
• Lead-free And RoHS Computing
• Energy Efficient Computing

10. Role Of IT Vendors
• Apple
• Wipro
• Google

11. Energy Use of PCs
• CPU uses 120 Watts
• CRT uses 150 Watts
– 8 hours of usage, 5 days a week = 562 Kwatts
– for a large institution, say a university of 40,000
students and faculty, the power bill for just computers
can come to $2 million / year
• Energy use comes from
– electrical current to run the CPU, motherboard,
memory
– running the fan and spinning the disk(s)
– monitor (CRTs consume more power than any other
computer component)

• Saving The Planet

17. Recent Implementations
Blackle
Fit-PC
Zonbu computer
Sunray thin client
The Asus Eee PC
Other implementations

19. Future Of Green Computing
The plan towards green IT should include new
electronic products and services with optimum
efficiency and all possible options towards
energy savings.

20. Conclusion
The greenest computer will not miraculously
fall from the sky one day, it’ll be the product of
years of improvements. The features of a green
computer of tomorrow would be like: efficiency,
manufacturing & materials, recyclability,
service model, self-powering, and other trends.
