  1. SUSTAINABLE ICT IN UNIVERSITIES AND COLLEGES - What is it, and how can we achieve it? Peter James and Lisa Hopkinson www.susteit.org.uk

  2. WHY BOTHER? • A moral duty- environmental degradation- extreme social exclusion • Tangible self interest- rising electricity costs- increasing regulation • Intangible self interest- reputation- relevant curricula and research

  3. THE BALANCE SHEET • ICT ‘SUPPLY’- Energy and resource intensive, and polluting, production- (Sometimes) poor working conditions- High energy use in equipment • ICT ‘DEMAND’- Travel substitution- Resource efficiency e.g. admin- Social inclusion- Awareness and information

  4. WHERE DOES THE POWER GO? • University of Sheffield- 18% of total non-residential electricity- PCs 48%- Servers 18%- High performance computing 14%- Imaging10%- Networking 8%

  5. WHAT ARE THE WHOLE LIFE IMPACTS? Transport Manufacture Materials Use Disposal

  6. WHAT CAN WE DO - ADMIN? • IT pays the energy bills • Better, more widely applied, whole life costing models • More cross-functional activity- especially IT and Estates

  7. WHAT CAN WE DO – TECHNICAL? • Simple measures- powerdown; lower power devices; grid computing; life extension- print management; easier duplex etc- energy efficient config & eqt in data centres • Complex measures- thin client; virtualisation; storage; software

  8. BACKGROUND • Higher Education Environmental Performance Improvement- Green Gown Awards - www.heepi.org.uk • Sustainable IT in Tertiary Education- Strategic review of IT in universities- Identifying & disseminating good practice- www.susteit.org.uk

  9. AN INVISIBLE BURDEN ~30 components ~28 kg materials ~35 kg production waste ~32 kg use-related waste assoc. ~end of life

  10. LIFE CYCLE WASTE FROM PCS Source: IVF, 2007. Preparatory studies for Eco-design Requirements of Energy Using Products

  11. LIFE CYCLE ENERGY FROM PCS Source: IVF, 2007. Preparatory studies for Eco-design Requirements of Energy Using Products

  12. LIFE CYCLE ENERGY OF PRINTERS Source: Franzhofer IZM and PE Europe, 2007. Preparatory studies for Eco-design Requirements of EuPs

  13. ELECTRICITY CONSUMPTION • UK- ICT 10% of total- fastest growing component • University of Sheffield- 16% + of electricity- 13% + of carbon emissions • High wastage- CPUs 10-20% utilisation- Eqt switched on www.gridcomputingnow.org

  14. WHY IT MATTERS TO FHE • Cost- 50 to 100% rise in electricity prices? • Carbon- growing regulation- Carbon Reduction Commitment • Capacity

  15. The Coal-Powered Computer

  16. PROCUREMENT - REDUCING ENERGY IMPACTS IN USE • Fit for purpose – faster, higher spec machines generally use more energy • PCs: laptops 50-80% less energy than desktop/CRT; LCD monitor 50% less energy than CRT • Imaging: Inkjets less energy than laser; b/w less energy than colour; MFDs less energy than SFDs. Duplex facility essential • Consider energy use in idle and standby • Procure the most energy efficient equipment that meets requirements

  17. PROCUREMENT – REDUCING ALL IMPACTS OVER LIFE-CYCLE • Dematerialise – smaller, lighter devices: MFDs rather than SFDs; laptops or thin clients rather than desktops; LCDs rather than CRTs • Extend useful life of product – recycle internally and refurbish • Reduce toxic compounds – as of 1/2/08 all EEE on market should comply with ROHS • Facility to return product to producer end of life, free of charge

  18. PROCUREMENT – REDUCING IMPACTS OF PAPER • Duplex facility for imaging equipment • Built in user codes to record usage • Print management software (e.g. GreenPrint) • Procure recycled paper (lower embodied energy) and ensure high rates recycling • Educate users- review/store online

  19. GREEN DESKTOPS • Powerdown networked computers • Switch off and power manage computers & peripherals • Grid computing • Thin client

  22. ENERGY EFFICIENT SERVERS Adapted from US EPA original Better air management Free/efficient cooling Efficient liquid cooling Flexibility and control Power efficiency & management Consolidation/Virtualisation Information life cycle management Power Conversion & Distribution Server Load/ComputingOperations Cooling Equipment On-site renewables Waste heat for cooling Fuel cells Thermal storage High voltage distribution Use of DC power Highly efficient UPS systems Efficient redundancy strategies AlternativeEnergy Supply

  23. OVERCOMING BARRIERS • Lack of awareness and information- footprinting and energy bills • Unsupportive financial frameworks- whole life costs • Lack of capacity- departmental champions; networks
