SBC Green IT ISACA 2011 05 17

  1. 1. Green IT– An Important Piece in the Puzzle<br />ISACA, 17 May 2011<br />Sustainable Business Consulting Pty Ltd<br />Level 32, 101 Miller Street, North Sydney 2060<br />P: 1300 102 195 | F: +61 2 8079 6101<br />www.sustainablebizconsulting.com.au <br />ACN 140 233 932 | ABN 46 506 219 241<br />Accredited by the NSW Government – On the panel of preferred suppliers<br />
  2. 2. Agenda<br />Drivers for Green IT<br />Australia’s emissions and legislation<br />Definition of Green IT<br />IT’s contribution to the carbon footprint<br />Data centres<br />PCs and peripherals<br />IT as an enabler<br />
  3. 3. The Drivers for Green IT<br />
  4. 4. It All Starts With the Science…<br />IPCC 2007<br />
  5. 5. … Which Causes Worldwide Governments to Mitigate the Risk<br />Collectively the major economies of our world account for over 70% of the world’s emissions<br />Adapted from: Globe Climate <br />Legislation Study, April 2011<br />
  6. 6. The World is Moving to a Carbon Constrained Economy<br />Qantas will be hit with a penalty by the European Union because Australia does not have a price on carbon.<br />A carbon trade barrier!<br />
  7. 7. Australia’s Emissions Intensity<br />top emitter per capita<br />Source: Garnaut Climate Change Review Update 2011, Update Paper 2<br />
  8. 8. Australia’s Emissions: Minus 5% from 1990 Levels by 2020<br />1990 levels<br />From http://www.climatechange.gov.au/~/media/publications/projections/tracking-to-kyoto-and-2020.ashx<br />
  9. 9. Australia Will Act and Bits and Pieces are Already in Place<br />NGER Act Thresholds<br />
  10. 10. Other Drivers for Green IT<br />Operational efficiencies<br />Rising electricity prices (estimates: double the price by 2015)<br />Corporate social responsibility<br />NGO pressure (CDP, Greenpeace, etc.)<br />Supply chain pressures<br />Investor pressure<br />Customer pressure<br />
  11. 11. What is Green IT<br />
  12. 12. What is Green IT<br />Storage Devices<br />Smartphones<br />Monitors<br />Devices<br />Laptops<br />Printers<br />Comms systems<br />Netbooks<br />Computers<br />Servers<br />Networking equip.<br />Data Centres<br />Lifecycle<br /> efficiently and effectively with minimal impact to the environment<br />Reduce <br />hazardous materials<br />Initiatives<br />Reduce <br />carbon footprint<br />Maximise recyclability<br />Maximise <br />energy <br />efficiency<br />Minimise depletion <br />of natural resources<br />
  13. 13. Carbon Footprint of IT<br />Globally: 2% of all carbon emissions (~ 600 Mt CO2-e)<br />Projected to rise to 3% in 2020 under BAU conditions<br />In your company: IT’s contribution to the carbon footprint might be 40% <br />Try to imagine IT’s footprint of cloud providers (Google, Amazon, Yahoo, FB, Twitter, IBM, HP, Microsoft, Apple, etc.)<br />What are the concerns:<br />Embedded energy in devices<br />Energy use in data centres<br />Energy use in endpoints (computers, laptops, etc.)<br />Disposal after end-of-life<br />
  14. 14. Datacentre Footprints<br />
  15. 15. Data Centres – The Factories of the 21st Century<br />
  16. 16. The Energy Use of a Typical Data Centre<br />Less than 15% of original source energy is used for the IT equipment within a data centre. Some estimates say only 3%!<br />
  17. 17. PUE – Power Usage Effectiveness<br />PUE =𝑇𝑜𝑡𝑎𝑙 𝐸𝑛𝑒𝑟𝑔𝑦 𝑐𝑜𝑛𝑠𝑢𝑚𝑒𝑑 𝑏𝑦 𝑡h𝑒 𝐷𝑎𝑡𝑎 𝐶𝑒𝑛𝑡𝑟𝑒𝐸𝑛𝑒𝑟𝑔𝑦 𝑠𝑢𝑝𝑝𝑙𝑖𝑒𝑑 𝑡𝑜 𝐼𝑇 𝑒𝑞𝑢𝑖𝑝𝑚𝑒𝑛𝑡<br /> <br />PUE of 2.0 means: <br />1 kw<br />IT equipment<br />2 kw <br />1 kw<br />power transformers, switch gear, UPS, A/C<br />
  18. 18. The Race for the Lowest PUE<br />PUE = 1.07!<br />
  19. 19. PUE is important, but what about the Carbon Emissions?<br />Carbon Usage Effectiveness<br />CUE = EF x PUE<br />Ideal CUE value = 0.0 (no carbon emissions!)<br />Assumptions: 2,000 kwh energy consumed by data centre<br /> 1,000 kwh energy consumed by IT equipment<br />CUE becomes really relevant with a price on carbon…<br />PUE:2,000 ÷1,000=  2<br /> <br />CUE: 0.9 ×2 = 1.80 in NSW<br /> <br />0.32 × 2 = 0.64 in TAS<br />1.23 ×2 = 2.46 in VIC<br /> <br />
  20. 20. Renewable Energy, Bought or Self-Generated<br />Iceland, powered by 100% geothermal and hydropower energy<br />Source: http://www.datacenterknowledge.com/archives/2009/06/16/solar-power-at-data-center-scale/<br />Googleplex<br />Source: http://www.datacenterknowledge.com/archives/2011/04/21/google-buys-wind-power-to-green-oklahoma-grid/<br />
  21. 21. Examples of Green IT Initiatives for Data Centres<br />Weed out low or nonperforming components<br />Plug holes – no mixing of cool and warm air<br />Adjust A/C settings<br />Use outside cooler air where you can (air-side economisation)<br />Energy efficiency for IT equipment:<br />Virtualisation<br />Cloud Computing<br />Outsourcing<br />Server specs: Performance per watt<br />Choose high-efficiency power supplies<br />Data Centre design (A/C, location, etc.)<br />Purchase renewable energy or generate on site<br />Co-gen or Tri-gen<br />
  22. 22. PCs and Peripherals Footprint<br />
  23. 23. Powering Computers, Laptops and Screens<br /> Simplified assumptions: <br /> Company in NSW, 3500 employees, everyone has computer and LCD screen<br /> Scenario 1: Computer and screen left on all the time<br /> Scenario 2: Power management enabled <br />80% cost savings<br />80% CO2-e reduction<br />
  24. 24. Green IT for PCs and Peripherals<br />Purchase energy star equipment<br />Install and enable power management software<br />Shift from desktop to laptops<br />Thin clients<br />Lengthen machine life with Linux<br />Purchase non hazardous material<br />Purchase material that is easily recyclable<br />Printer and paper usage management<br />Donate end-of-life equipment<br />
  25. 25. IT As An Enabler<br />
  26. 26. IT Has a Large Potential to Reduce Our Carbon Footprint<br />IT can lead to emission reductions 5x the size of the sector’s own footprint<br />Dematerialisation – moving bits instead of atoms (e.g. telecommuting, e-billing, e-commerce, e-government, digital music)<br />Smart electricity grids (largest opportunity)<br />Smart buildings (building design, heating, cooling, lighting, appliances)<br />More efficient transport (route optimisation, RFID for asset tracking, GIS, GPS, etc.)<br />Leaner industrial processes (VSDs)<br />IT will help track and manage carbon footprints – Carbon Management Software<br />
  27. 27. What Can You Do?<br />
  28. 28. How Can You Get Started on Green IT?<br />Assess current state of sustainability<br />Get executive buy-in – sell the business case for Green IT<br />Build a green team<br />Baseline your data – you can’t manage what you don’t measure<br />Get the vision right, set targets<br />Prioritise your goals<br />Identify specific initiatives<br />Engage staff<br />Implement quick wins and build up confidence<br />Use money saved by green initiatives for more capital-intensive green projects<br />Share your success stories<br />
