Green Computing (绿色计算)
Green Computing (绿色计算) • It is an environmental friendly IT (Information Technology-信息技术) , whose aim is to reduce the hazardous materials (危险材料) and maximize the energy efficiency (能源效率) • It is also called Green IT. (绿色 IT)
Green Computing (绿色计算) • hazardous materials (危险材料) – Hardware concern
• energy efficiency (能源效率) – Both hardware and software concerns
Why is Green Computing required ? • Computers consumes a lot of energy • Printing often unnecessary stuff is waste • Reduce pollution • Control toxicity
Green Computing History • It originated in 1992 at the U.S Environmental Protection Agency that lauched the Energy Star program • Shortly after that, the term “Green Computing” was coined. • Shorlty after that, the Swedish also lauched the TCO Certification
Pathways to Green Computing • Green Design • Green Manufacturing • Green Disposal • Green Use • Green Application Development
Approaches to Green Computing • Product longevity • Materials recycling • Power Management • Sofware and deployment optimization • User consciousness
Methods to Implement Green Computing ROHS= Restriction Of Hazardous Substances Lead (Pb), Cadmium (Cd), Mercury (Hg)…

• Sugar powered batteries (Sony)
Solar Computing (太阳能计算)
Quiet Computing (安静的计算)
Best Practices - USER • Turn off the computer when not in use, even if just for an hour • Turn off the monitor when not in use (as opposed to running a screen saver) • Use power save mode • Do not throw batteries on the environment • Use LCDs instead of CRTs • Do not print unless required
Best Practices - PROGRAMMERS

II – THE JUDGEMENT
The Fact and defense/prosecution • Data generation is being prosecuted for high computing resource consumption (storage, energy,…) • On pairs, you have to decide to defending or prosecuting data generation. – Write three reasons (and explain them) to support your position (˜15 minutes)
The Judgment • I will choose 10 students to compose the jury. The jury has to pay attention on arguments presented by the lawyers (~10 min). • Each jury component will decide if “Data Generation” is guilty or not. If guilty, jury has to suggest a penalty (a set of best practices) (~10 min).
Thank you!
