    • Green IT– An Important Piece in the Puzzle
      ISACA, 17 May 2011
      Sustainable Business Consulting Pty Ltd
      Level 32, 101 Miller Street, North Sydney 2060

      Accredited by the NSW Government – On the panel of preferred suppliers
    • Agenda
      Drivers for Green IT
      Australia’s emissions and legislation
      Definition of Green IT
      IT’s contribution to the carbon footprint
      Data centres
      PCs and peripherals
      IT as an enabler
    • The Drivers for Green IT
    • It All Starts With the Science…
      IPCC 2007
    • … 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
    • 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!
    • Australia’s Emissions Intensity
      top emitter per capita
      Source: Garnaut Climate Change Review Update 2011, Update Paper 2
    • 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
    • Australia Will Act and Bits and Pieces are Already in Place
      NGER Act Thresholds
    • 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
    • What is Green IT
    • What is Green IT
      Storage Devices
      Comms systems
      Networking equip.
      Data Centres
      efficiently and effectively with minimal impact to the environment
      hazardous materials
      carbon footprint
      Maximise recyclability
      Minimise depletion
      of natural resources
    • 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
    • Datacentre Footprints
    • Data Centres – The Factories of the 21st Century
    • 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%!
    • 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
    • The Race for the Lowest PUE
      PUE = 1.07!
    • 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
    • Renewable Energy, Bought or Self-Generated
      Iceland, powered by 100% geothermal and hydropower energy

    • 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:
      Cloud Computing
      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
    • PCs and Peripherals Footprint
    • 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
    • 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
    • IT As An Enabler
    • 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
