This document discusses green computing, including its origins, advantages, and pathways. It began in 1992 with Energy Star, which promoted energy efficiency. Green computing aims to reduce environmental impacts and costs through energy efficiency, reducing waste, and recycling electronics. It allows cost savings, uses less resources, and lessens health risks from toxic materials. Sri Lanka has e-waste collection centers and standards to minimize impacts. The future of green computing involves virtualization, more energy savings, eco-friendly materials, and increased recycling.
Green computing
- 2. Introduction Origin E-Waste Advantages & Disadvantages of green computing Pathways to green computing Sri Lankan approaches Future of green computing CONTENT
- 3. Green Computing can be described as the environmentally responsible usage of computer systems and related resources.
- 4. Contd……. It is also known as the study & practice of manufacturing, using & disposing of computers, servers & associated subsystems efficiently & effectively.
- 5. ORIGIN In 1992,the U.S Environmental Protection Agency launched “Energy Star”,a labeling programm designed to promote & recognize energy efficiency in monitors, climate control equipments and other technologies. The term GREEN Computing was coined shortly after energy star programme.
- 6. Contd… …. Concurrently, the Swedish organization TCO Development launched the TCO certification program to promote low magnetic and electrical emissions from CRT-based COMPUTER DISPLAYS. The energy star program was revised in October 2006 to include stricter efficiency requirements for computer equipment, along with a tiered ranking system for approved products.
- 7. 1.The main reason is the growing of public environmental awareness. 2.To reduce energy wastage. 3.It helps to save a lot of money.
- 8. 4.To reduce power consumption. 5.To reduce impacts on environmental & human health. The main aim is to reduce the amount of carbon emissions.
- 9. 6.To avoid toxicity. Lead:-can cause damage to the central & peripheral nervous system. Mercury:-can cause chronic brain damages. Cadmium:-accumulate in the human body specially the kidney. 7.To reduce IT maintenance activities. 8.To reduce the paper & other consumables used. 9.A corporate social responsibility. 10.A step for need of tomorrows future.
- 10. E-Waste Definition • Any discarded electronic or electrical devices or their parts; also called electronic waste • Examples: Computers, LCD / CRT screens, cooling appliances, mobile phones, etc., contain precious metals, flame retarded plastics, CFC foams and many other substances.
- 11. METHODS OF DISTROYING WASTE Hazardous Technologies Recycling Technologies Open Burning Land filling 1. Detoxication 2. Refining 3. Shredding
- 12. MercuryLead Arsenic Polychlorinated Biphenyls (PCBs)Toner Some Hazardous Components of E-Waste and Effects on Humans
- 13. •Renal Toxicity •Anemia •Colic •Insomnia •Seizures •Coma In Children •Renal toxicity •Muscle tumors •Mental retardation •Cerebral palsy
- 14. •Cancer Of Skin •Lungs •Liver •Respiratory Tract Irritation •Suppression Of Immune System •Damage To The Liver • Nervous •Reproductive Systems
- 15. Energy & Resources Saving Environmentally Friendly Cost Effective Save Space Reduce the Risk of Harmful Chemicals
- 16. Disadvantages of Green Computing • High startup cost • Not readily available • Still in Experimental stage • Not for everyone • High maintenance cost
- 17. 1. Buy "Energy Star" labeled monitors, desktops, laptops, and printers 2. Put laptops in "sleep" mode or “Hibernate” mode when not in use Pathways to green computing
- 18. 3. Turn OFF computers and other equipments when not in use 4. E-cycle used computer equipments 5. Buy the new “Smart Strip” power strip 6.Set “Blackle” as your homepage
- 19. 7. Use LCDs instead of CRTs as they are more power efficient - CRT uses 150 Watts 8 hours of usage, 5 days a week=562KWatts If the computer is left on all the time, without proper power saver modes, this can leads to 1,600KWatts. 8. Buy Green products
- 21. E-Waste Management • Sri Lankan Government has been initiated e-waste collecting centers. • Ceylon Waste Management and their Material Refining Process . Sri Lankan Approach of Green Compu
- 22. Companies and Organizations • Most of Sri Lankan Companies and Organizations already have took the first step to Green Computing.
- 23. • Following Standards for minimizing health effects and environmental effects. Following Standards
- 24. 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 “ The future of Green Computing will be full of … • Virtualization • Energy Saving • Eco Friendly Materials • Recycling And etc.
- 25. Virtualization Virtualization, in simple terms, is moving physical servers to virtual ones. What is Virtualization ? Why is it important? Few of the most important features of virtualization is that it… Saves money Saves energy Reduce e-waste
- 26. Technologies used for Virtualization Microsoft Virtual Server VMware Future of Virtualization VMware’s Virtualization Progress Did you know ? 50-60% of all servers are now virtualized
- 27. Natural Cooling Systems Smart Plug Solar Systems Eco-Friendly mobile chargers Energy Saving
- 28. Eco Friendly Materials Mercury-free backlighting and arsenic-free glass in displays Not using Lead, Chromium Mercury and other toxic chemicals for manufacturing computer devices Using recyclable or digital newspapers
- 29. Recycling In future, almost all the computer devices and items will be able to be recycled Recyclable PCBs Recyclable Batteries Take-back concept of the manufactures
- 30. That’s all about the future of Green Computing It’s not easy not being green So, Let’s Go Green!
Editor's Notes
- #11: E-Waste for short - or Waste Electrical and Electronic Equipment - is the term used to describe old, end-of-life or discarded appliances using electricity. It includes computers, consumer electronics, fridges etc which have been disposed of by their original users. "e-waste" is used as a generic term embracing all types of waste containing electrically powered components. e-Waste contains both valuable materials as well as hazardous materials which require special handling and recycling methods. This guide covers all categories of e-waste but emphasizes categories which contain problematic, scarce and valuable or otherwise interesting materials.
