The document presents best practices for achieving return on investment through energy-efficient computing, emphasizing the importance of reducing IT energy waste and improving computing efficiency by 50% by 2010. It includes case studies demonstrating significant savings in energy costs and CO2 emissions through better power management and the adoption of high-efficiency hardware. The Climate Savers Computing Initiative aims to influence organizations to adopt these practices for financial and environmental benefits.

6. The Problem: IT Energy Waste in Germany
• Every day 156 million employees in the US, the UK and
Germany decide whether or not to shut down their PCs
• A German company with 10,000 PCs through not shutting
down PCs wastes annually:
• 1.5 million kWh
• €285,000
• 887 tons CO2 emissions
• 58 percent of German employees feel that their companies
should be doing more to reduce power consumption
• Only 2 percent of German employees shut down their PCs

14. Fujitsu Case Study

15. Case Study: Südwestrundfunk (SWR)
Südwestrundfunk (SWR) is a public broadcasting
institution for the regions of Baden-Württemberg
and Rhineland-Palatinate. 14.7 million people live
in its coverage area. SWR is the second largest
public broadcasting institution in Germany.
In order to further optimize energy-efficiency in IT
and to contribute to climate protection, SWR has
decided to iinstall 3500 FUJITSU ESPRIMO 0-
Watt PC-systems over the next 2 years.
FUJITSU estimates that these new systems will
generate annual power-savings of approximately
310 MWh, which translates into 46.450 € annual
energy-cost savings and a CO2-reduction of 192 t.
