This document discusses Green IT and its importance. It defines Green IT as using IT technologies efficiently and effectively while minimizing environmental impact across the entire lifecycle. IT contributes an estimated 2-3% of global carbon emissions. Data centers are large energy users, with typical centers using only 3-15% of energy on IT equipment. Adopting practices like virtualization, cloud computing, and renewable energy can help reduce the carbon footprint of data centers and devices like PCs. IT also enables reductions in other sectors through applications like telecommuting, smart grids, and supply chain optimization. The document provides tips for organizations to assess their current sustainability, set goals and priorities, and implement initiatives to begin reducing their environmental impact through Green IT.

3. The Drivers for Green IT

4. It All Starts With the Science… IPCC 2007

5. … Which Causes Worldwide Governments to Mitigate the Risk Collectively the major economies of our world account for over 70% of the world’s emissions Adapted from: Globe Climate Legislation Study, April 2011

6. The World is Moving to a Carbon Constrained Economy Qantas will be hit with a penalty by the European Union because Australia does not have a price on carbon. A carbon trade barrier!

7. Australia’s Emissions Intensity top emitter per capita Source: Garnaut Climate Change Review Update 2011, Update Paper 2

8. Australia’s Emissions: Minus 5% from 1990 Levels by 2020 1990 levels From http://www.climatechange.gov.au/~/media/publications/projections/tracking-to-kyoto-and-2020.ashx

9. Australia Will Act and Bits and Pieces are Already in Place NGER Act Thresholds

10. Other Drivers for Green IT Operational efficiencies Rising electricity prices (estimates: double the price by 2015) Corporate social responsibility NGO pressure (CDP, Greenpeace, etc.) Supply chain pressures Investor pressure Customer pressure

11. What is Green IT

12. What is Green IT Storage Devices Smartphones Monitors Devices Laptops Printers Comms systems Netbooks Computers Servers Networking equip. Data Centres Lifecycle efficiently and effectively with minimal impact to the environment Reduce hazardous materials Initiatives Reduce carbon footprint Maximise recyclability Maximise energy efficiency Minimise depletion of natural resources

13. Carbon Footprint of IT Globally: 2% of all carbon emissions (~ 600 Mt CO2-e) Projected to rise to 3% in 2020 under BAU conditions In your company: IT’s contribution to the carbon footprint might be 40% Try to imagine IT’s footprint of cloud providers (Google, Amazon, Yahoo, FB, Twitter, IBM, HP, Microsoft, Apple, etc.) What are the concerns: Embedded energy in devices Energy use in data centres Energy use in endpoints (computers, laptops, etc.) Disposal after end-of-life

14. Datacentre Footprints

15. Data Centres – The Factories of the 21st Century

16. The Energy Use of a Typical Data Centre Less than 15% of original source energy is used for the IT equipment within a data centre. Some estimates say only 3%!

17. PUE – Power Usage Effectiveness PUE =𝑇𝑜𝑡𝑎𝑙 𝐸𝑛𝑒𝑟𝑔𝑦 𝑐𝑜𝑛𝑠𝑢𝑚𝑒𝑑 𝑏𝑦 𝑡h𝑒 𝐷𝑎𝑡𝑎 𝐶𝑒𝑛𝑡𝑟𝑒𝐸𝑛𝑒𝑟𝑔𝑦 𝑠𝑢𝑝𝑝𝑙𝑖𝑒𝑑 𝑡𝑜 𝐼𝑇 𝑒𝑞𝑢𝑖𝑝𝑚𝑒𝑛𝑡 PUE of 2.0 means: 1 kw IT equipment 2 kw 1 kw power transformers, switch gear, UPS, A/C

18. The Race for the Lowest PUE PUE = 1.07!

19. PUE is important, but what about the Carbon Emissions? Carbon Usage Effectiveness CUE = EF x PUE Ideal CUE value = 0.0 (no carbon emissions!) Assumptions: 2,000 kwh energy consumed by data centre 1,000 kwh energy consumed by IT equipment CUE becomes really relevant with a price on carbon… PUE:2,000 ÷1,000= 2 CUE: 0.9 ×2 = 1.80 in NSW 0.32 × 2 = 0.64 in TAS 1.23 ×2 = 2.46 in VIC

21. Examples of Green IT Initiatives for Data Centres Weed out low or nonperforming components Plug holes – no mixing of cool and warm air Adjust A/C settings Use outside cooler air where you can (air-side economisation) Energy efficiency for IT equipment: Virtualisation Cloud Computing Outsourcing Server specs: Performance per watt Choose high-efficiency power supplies Data Centre design (A/C, location, etc.) Purchase renewable energy or generate on site Co-gen or Tri-gen

22. PCs and Peripherals Footprint

23. Powering Computers, Laptops and Screens Simplified assumptions: Company in NSW, 3500 employees, everyone has computer and LCD screen Scenario 1: Computer and screen left on all the time Scenario 2: Power management enabled 80% cost savings 80% CO2-e reduction

24. Green IT for PCs and Peripherals Purchase energy star equipment Install and enable power management software Shift from desktop to laptops Thin clients Lengthen machine life with Linux Purchase non hazardous material Purchase material that is easily recyclable Printer and paper usage management Donate end-of-life equipment

25. IT As An Enabler

26. IT Has a Large Potential to Reduce Our Carbon Footprint IT can lead to emission reductions 5x the size of the sector’s own footprint Dematerialisation – moving bits instead of atoms (e.g. telecommuting, e-billing, e-commerce, e-government, digital music) Smart electricity grids (largest opportunity) Smart buildings (building design, heating, cooling, lighting, appliances) More efficient transport (route optimisation, RFID for asset tracking, GIS, GPS, etc.) Leaner industrial processes (VSDs) IT will help track and manage carbon footprints – Carbon Management Software

27. What Can You Do?

28. How Can You Get Started on Green IT? Assess current state of sustainability Get executive buy-in – sell the business case for Green IT Build a green team Baseline your data – you can’t manage what you don’t measure Get the vision right, set targets Prioritise your goals Identify specific initiatives Engage staff Implement quick wins and build up confidence Use money saved by green initiatives for more capital-intensive green projects Share your success stories
