  1. 1 Comparison of Two ICT Solutions Desktop pc versus Thin client computing

  2. 2 Overview • Introduction • Methods of Analysis • Important Findings of Paper • Causes for the Differences Between the Two Scenarios • Questions

  3. 3 Introduction • Comparison of Two ICT Solutions: Desktop PC versus Thin client computing • Written by Daniel Maga, Markus Hiebel and Christian Knermann- Published September 2012 • Compares traditional desktop PC computing model to thin client model: • Environmental Perspective • Highlights and explains the differences

  4. 4 Introduction Desktop PC Thin Client Computing Vs. • Standalone device • Network connection not essential • Server performs all computational functions • Needs a network connection

  5. 5 Methods of Analysis 2 methods used to measure environmental impacts of ICT products throughout their lifecycle • Methodology for Ecodesign of Energy-related products (MEErp) – emissions & Global Warming Potential (GWP) • Material Input Per Service (MIPS) – Materials used in lifecycle (Material, water & air)

  6. 6 Methods of Analysis Material Extraction & Production Manufacturing Distribution End of Life Use

  7. 7 Important Findings • Negative Impact to the environment caused by Desktop PC model is significantly greater than Thin Client computing

  8. 8 Important Findings • Thin Client Savings • Material 1.8 tonnes • Water 21 tonnes • Air 0.2 tonnes

  9. 9 Important Finding • The use stage represents the biggest impact to the environment – use of electricity

  10. 10 Important Finding • Regardless of model still potential for further improvements e.g. Coating on rear panel of thin client results in high emissions. Further Improvements Eco-Design initiatives Improvements in virtualisation, cloud computing benefits for both models Help to reduce the demand for energy and resources

  11. 11 Causes for the Differences Between the Two Scenarios • Causes • Less electronics used in thin clients - surface-mounted devices, integrated circuits, • and copper–nickel alloys • No hard drive, minimal RAM, less I/O ports, CD drive in thin client

  12. 12 Causes for the Differences Between the Two Scenarios Causes Server performs all computation of thin client – energy savings multiplied by no. of client. Workplace attitude – 30% of systems not turned off at night or never turned off
