ICT-Enabled Energy Efficiency


Published on

Energy-efficiency is the most promising way to substantially address the global energy- and climate-issues in the near-term. Information and Communication Technology (ICT) is a leading enabler of energy-efficiency by limiting the carbon footprint of the ICT sector itself but also by providing the basis to increase efficiency in other sectors.

Dr. Bernd Kosch, Head of Environmental Technology, Fujitsu Technology Solutions provides an overview of current technology and expected short-term potentials, as well as a positioning of ICT with respect to the new Energy Efficiency Plan of the European Union.

  12. 12. Server-Energy-Cost An exercise in power-cost-calculation • Topic: Replacemnt of 3 2008-systems ( described above) by 1 system of p p y (as ) y y 2011 (at all load-levels, 1 new systems has better performance than 3 older systems) • Assumption: • All-year 7*24 operation: approx. 8400 hours of operation during 350 days • Load-distribution: 1/3 peak-load 1/3 50%-load, 1/3 active-idle • This results in a delta power-consumption of: • 8,400 * ((265+224+166) - (236+151+75)/3) = 8,400 * (655 – 154) = 4,208,400 • 4,208 kWh of server-energy result, at an assumed PUE of 1.6, in 6,733 kWh at the data center level. • At an electricity price of 13 c/kWh, savings in energy-cost sum up to 875 € energy cost p.a., for small companies and „normal“ PUE-levels to more than 1.000 € p.a. Long depreciation periods do not make sense for servers L d i i i d d k f 11 Copyright 2011 FUJITSU
  13. 13. Client-Virtualization („Zero Client“) A Zero-Client-based workplace consumes similar amounts of power as the monitor of a classical PC-based desltop The configuration rule for servers, which host the virtual machines of Zero-Clients imposes a limit of VMs per CPU- core Accordingly, a server like the PRIMERGY TX300 S6 (as described above) can host 8 * 6 * 2 = 96 virtual clients, representing between 0 8 and 2,8 W of server-power 0,8 28 server power depending on the aggregate load-level For 32 virtuelle clients on a PRIMERGY TX140 S1 the respective figures are: 0,5 to 1,7 W Client-virtualization and Thin-Client-concepts are offering advantages regarding safety and security. Improved energy-efficiency p gy y provides additional cost-savings. g 12 Copyright 2011 FUJITSU
  14. 14. “Green” beyond Private Scope Limiting global warming at the level of 2 0C 1) • Implies a limit of additional CO2-emissions of approx. 700 Gt in total p pp (eternal) (global emissions are now at approx. 32 Gt p.a., increasing) • Is, for economic reasons, only compatible with descend-paths that reverse the trend of increase before 2015 • and is therefore NOT a problem of future generations but is a problem that can only be resolved today – by THIS generation Alternatives for the descend-phase35%• „less CO2 in consumed energy”, Replacement of fossile fuels60%• ”less energy in material welfare” gy Improvement of energy-efficiency p gy y 2) 5%• “less welfare“ (Reduction of (irrational) luxury)) 1) Since the beginning industrialization - increase of average temperature since 1900 amounts to approx. 0.7 0C 2) Translated quote from a speech by E.-U. v.

  15. 15. Energie-Efficiency Potentials BY ICT Potentials (in other sectors) BY the use of ICT • „SMART“-sectors (GeSI Climate Group: SMART 2020 report) provide SMART“ sectors (GeSI, (probably) ICT-related CO2-reduction-potential of approx. 15% of the 1990 level (global) by 2020 • ICT-related efficiency in horizontal / automation- processes has (probably) significant potentials as well • However: scientifically sound methods for the quantitative y q assessment of the ICT-related “enabling-effect“ are not yet mature and, therefore, do not qualify as a basis for new legal frameworks • Energy-efficiency management is a necessary requirement for target- oriented optimization of energy consumption. Present estimations and related commitments by policy makers and business-leaders have policy-makers business leaders been lacking standardized quantitative foundations, so far. 14 Copyright 2011 FUJITSU

  26. 26. Perspectives Consolidation of central ICT and virtualization up to the level of client-systems continues to provide significant cost- reduction potential by improving energy-efficiency. p y p g gy y In SME these potentials are not yet fully understood by all market participants. For client-systems such potentials may be insignificant for some SMEs SMEs. The upcoming energy-efficiency legislation in the EU-27 will result in Directing public PC-procurement to the highest energy-efficiency class, thus turning public offices into role models Adoption f Ad ti of energy-efficiency management by a l ffi i tb large group of EU 27 f EU-27 enterprises, thus increasing awareness about efficiency opportunities and creating additional incentives to reduce CO2-emissions. Standardized St d di d assessment methodologies will d i tif the t th d l i ill demistify th ICT-related enabling-effect and help optimizing energy-use Energy-efficiency IN and BY ICT is not a temporary hype – it cuts energy bills today and will cut tax burdens tomorrow 25 Copyright 2011 FUJITSU
