  1. COMP 2923Basics of Green IT Danny Silver JSOCS, Acadia University

  2. References • Chapter 2 of John Lamb’s “The Greening of IT”

  3. The Basics of Green IT • Major issues effecting Green IT Initiatives: • Government regulations • Government and Power Co. incentives • Corporate structure • Impact of Greening on organization • Product end-of-life and asset disposal

  4. Major Discussion Points • Organizational issues and going to Green IT • Regulations as factors for change • Motivation for executives to move to green data centers • Issues of product transportation and disposal • Important steps required for Green IT • Role of software, applications, process workload • Impact of distributed mobile equipment • Energy measurement and management

  5. Organizational issues and going to Green IT • Starts with who manages and controls IT power bill • It should be CIO – Why? • Developers and users should know measures of IT electricity • Areas of energy wasted: power supply, power distribution, cooling of work space

  6. Regulations as factors for change • Standards • CSA – Canadian Standards Association • Energy Efficiency Verification • Electromagnetic Compatibility Testing • Environment Product Peformance • Provincial • Provinces dictate law on recycling electronics • Federal • Tends to focus on federal government departments, nation defence, hazardous waste

  7. Motivation for executives to move to green data centers • dxsdvv Energy is about 10% of data centre budget in US and Canada Second largest line item. Much higher in other parts of the world

  8. Motivation for executives to move to green data centers • dxsdvv MtCO2e = Mega tonne CO2 equivalent = 1,000,000 tonne CO2 GtCO2e = Giga tonne CO2 equivalent = 1,000,000,000 tonne CO2

  9. Issues of product transporation and disposal • Products move • And die • It all costs

  10. Issues of product transporation and disposal • And there is the collateral paper, packaging, storage, incineration, landfill costs

  11. Important steps required for Green IT • Diagnose the opportunities and problems • Manage and measure • Cool more efficiently • Virtualize as much and as soon as possible • Build green when you build • Building envelope - Choose energy sources • Select green tech - Build culture

  12. IBM Big Green Approach • Diagnose the opportunities and problems • Get the facts on energy use and carbon footprint • Manage and Measure • Seize control of energy use with methods and systems • Cool • Make smart / economic choices • Virtualize • Replace multiple old systems with single new systems • Build / Rent • Plan, build more energy efficient facilities, or use the cloud

  13. Role of software, applications, process workload Reduce the cost of Data … • Processing: Algorithms not typically optimized to reduce energy use • Storage: Select lower power tech / options • Communication: Move to fibre optics • Take advantage of: • SOA = Service Oriented Architecture • SaaS = Software as a Service

  14. Ways to Reduce Process Workload • Replace paper forms with e-forms • Increase automation to achieve more with less environmental impact • Model and improve process sequences and workflows • Leverage charge-back accounting to enforce efficiencies • Address environmental regulations

  15. Beyond Green Data CentersImpact of distributed mobile equipment • http://www.sustainability-perspectives.com/article/the-four-key-environmental-factors-of-ict-energy-carbon-e-waste-and-water/ Some say as high as 4-6%

  16. Energy measurement and management • If you do not measure it, you cannot manage it • Culture must be the first thing to change • University of Colorado (p. 26 of Lamb), 2008: • 18,000 computers - $550,000 / year in energy • Plus cost to cool rooms with computers - $150,000 / year • Total - $770,000 • What do you estimate is Acadia’s PC/Laptop energy cost per year?

  17. Energy measurement and management • MIT – 20,000 PCs, saving an estimated 8 M KWH annually • Estimate 4% of overall energy can be saved =961 homes in Cambridge, Mass • Based on 14 idle hours per day a single desktop savings can be 500 KWH per year • Average home uses 700 KWH per month

  18. Energy measurement and management • Myths: • Screen savers save your screen • Computers have a shorter life when turned off/on • Turning your computer off/on uses more energy than leaving it on

  19. Useful Websites for PC Energy Reduction • When to Turn Off Personal Computers • http://energy.gov/energysaver/articles/energy-efficient-computer-use • How much electricity do computers use? • http://michaelbluejay.com/electricity/computers.html • http://www.makeuseof.com/tag/power-pc-technology-explained/ • http://www.nspower.ca/en/home/for-my-home/save-energy/energy-calculator.aspx • Five tips for reducing your computer’s energy use • http://www.treehugger.com/files/2007/01/reducing_your_c.php • Ways To Reduce Computer Energy Consumption • http://www.thesimpledollar.com/8-ways-to-easily-reduce-the-energy-consumption-of-your-computer-and-save-big-money/

  20. Videos • The Greening of Information Technology • http://www.youtube.com/watch?v=pQvtr7hUDNs • NASCIO:Taking the Lead: Green IT in the States • http://www.nascio.org/committees/green/greenITVideo.cfm
