  • 2. • Md. Shibbir Hossain ( BSSE-0317) PRESENTED BY
  • 3. OUTLINE • What is Green Computing • Roads to Green Computing • Origins • Why Green Computing • Computing resource utilization & economic impact • Problems faced by organizations • Areas of concern for organizations • Creation of vicious cycle • Impact
  • 4. OUTLINE • Considerations regarding tackling the situation • Measures for Green Computing • Information system & technologies used by giants • Barriers faced by organizations • Coping up with challenges • Result of using Information System • Implementation strategy for local companies • Green guidelines for computer users • Interactive Session
  • 5. What is Green Computing • Green computing is the environmentally responsible and eco-friendly use of computers and their resources( • 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
  • 13. Impact • Negative impact on environment • Increased corporate operating cost
  • 14. Considerations regarding tackling the situation • Keep an eye on saving the environment • Saving the dollars
  • 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
  • 18. Continued
  • 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
  • 25. Interactive Session
  • 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
  • 30. Questions?
  • 31. Thank you all!!!
