5. What is Green Computing
• Green computing is the environmentally responsible
and eco-friendly use of computers and their
resources(Technopedia.com)
• Defined as the study of
designing, manufacturing/engineering, using and
disposing of computing devices in a way that reduces
their environmental impact by sustaining or improving
performance.
6. Roads to Green Computing
• To promote green computing concepts at all possible
levels:
– Green use: minimizing electricity consumption
– Green disposal : recycling, remaking
– Green design: energy-efficient design
– Green manufacturing: minimizing waste during
manufacturing
7. Origins
• In 1992, the U.S. Environmental Protection
Agency launched Energy Star
– a voluntary labeling
program designed
to promote and recognize
energy-efficiency
8. Why Green Computing
• Reducing impacts on environmental and human health
• Corporate social responsibility
• A step needed for future
• Helps to minimize the energy consumption by
educating consumers on efficient ways to keep power
usage low
• Green branding- boosts corporate image
9. Computing resource utilization &
economic impact
• PCs typically stay more then twice the amount
being used each day
– A company with 10000 PCs ♡♡ $165000 per
year if left on all night
• Waste of $1.7 billion each year in US alone
10. Problems faced by organizations
• Computer rooms becoming hot to handle
• Data hungry tasks leading to power hungry machines
– Power and cooling costs for data centers skyrocketed to 800%
since 1996
11. Areas of concern for organizations
• Spend twice as much on energy as on hardware in next
5 years
• Heat generated from room full of servers causing
equipment to fail
• Spend more money to keep data center cool than actual
property
12. Creation of vicious cycle
Pay to
power the
server
Pay again
to keep
them cool
15. Measures for Green Computing
• Virtualization
• Algorithm Efficiency
• Power management
• Display
• Telecommuting
• Terminal servers
16. Information system & technologies used by
giants
• Google & Microsoft
• Hydroelectric power
17. Continued
• Hewlett-Packard
• New software and services to measure energy use and carbon emission
• Reduced power cost by 20 to 25% through consolidations of servers and
data centers
• Microsoft San Antonio
• Sensors to measure all power consumption
• Recycles water used in cooling
• Uses internally developed power management software
• Fulton County, Georgia serves 988,000 residents by VMWare
virtualization an Fujitso blade server
19. Barriers faced by organizations
• Many companies use default PC power management
setting
– But 70% employees turn them off
20. Coping up with challenges
• Software – BigFix, 1E nightwatchman, Verdiem
– Locks PC power settings
– Automatically power up PCs right before employees arrives
• CUNY- Verdiem surveyor software to turn off 20,000 PCs.
21. Result of using Information System
• 10% cut down from CUNY’s power
bill
– Approximately 320,000 savings annually
22. Implementation strategy for local
companies
• Better managing computing resources
• Programs to educate employees in energy conservation
– Honda Motor company
23. Green guidelines for computer users
• Use the hibernate or sleep mode when away from a
computer for extended periods
• Use flat-screen or LCD monitors, instead of
conventional cathode ray tube (CRT) monitors
• Buy energy efficient notebook computers, instead of
desktop computers
• Activate the power management features for
controlling energy consumption
24. Continued
• Make proper arrangements for safe electronic waste
disposal
• Turn off computers at the end of each day
• Refill printer cartridges, rather than buying new ones
• Instead of purchasing a new computer, try refurbishing
an existing device
26. What business and social problems does data
center power consumption cause?
1)Higher operating cost
2) Negative effect towards environment
3)Increasing carbon footprint mark leading to global
warming
4)Overheat causing servers to fail
5) More power consumption
27. What solutions are available for these
problems? Which are environment friendly?
1) Using centrally monitored power management
software
2) Training people/employees about energy
consumption
3) Better management of resources
4) Moving towards cloud computing
5) Telecommuting
6) Terminal servers
All of the solutions are environment friendly as they
reduce carbon emission.
28. What are the business benefits and costs of
these solutions?
1) Savings of dollars
2) Green Branding
3) CSR
4) Boosts corporate image
5) Sustainable technology
The cost of training is upto the managerial level.
Cost of using power management software.(For BigFix
$33 first year, $10 annually)
29. Should all firms move toward green
computing? Why or why not?
Of course yes. Reasons:
– Sustainable technology
– For sake of human existence
– For saving billions of dollars
– Next generation computing
