American Power Conversion (APC) published an informative white paper in 2006, Implementing Energy Efficient Data Centers, which showed that 45% of data center energy goes to dealing with waste heat. I've seen "half" frequently asserted without citation; if you have a more recent credible source, please post it as a comment.
Green ICT articles cite a wide range of variances between energy costs per square foot for data centers and for normal office space. Vertatique uses the range cited by Measuring and Managing Data Center Use: "energy costs per square foot that are 10 to 30 times that of typical office buildings"
The EPA's Report to Congress on Server and Data Center Energy Efficiency Public Law 109-431 is over a year old, but remains an important data source. Among its tipping point statistics: "Another impact of higher energy densities is that server hardware is no longer the primary cost component of a data center . . .
Forrester is promoting a $279 report under title "Is Green IT Your Emperor with No Clothes?" The author and his colleagues appear to have created a straw dog for the sake of a provocative title.
Adam Werbach, Global CEO of Saatchi & Saatchi, uses a Harvard Business Review podcast to offer insights into how to best implement enterprise sustainability. One idea is to engage employees by encouraging them to adopt PSPs: Personal Sustainability Practices. Vertatique's Personal e-Green section contains information that can form the basis of PSPs tied to an organization's Green ICT initiative.
Cisco's most recent TechwiseTV episode, Redefining the Remote Office, states that 91% of employees do not work in the corporate office and the number of branch offices is growing at ~11% CAGR. Here are ideas I took away from my preview:
Vertatique has gotten requests for more Green ICT media pieces; here are three recent ones of particular note:
- Google's Power and Green Computing is a strong presentation from July 2008 offering lots of solid data.
- Intel estimates its 8-year Data Center Efficiency Initiative could deliver up to $750 million in NPV.
Computerworld's The 5 quickest returns on your green investment is a quick summary of where to find what Gartner characterizes as "low hanging fruit" and "fat". Despite the mixed metaphor, statistics and case study references make this more useful than many summary articles.
Vertatique has been tracking the Climate Savers initiative over the past year and I'm pleased to see its site continue to grow in value. They now offer a robust set of free software applications to help individuals and enterprises tune the power settings of their equipment. I'll report on these tools as I try them out.
Cisco Systems will be contributing to advancing Green ICT awareness with a webinar titled "Energy Efficiency in the Data Center" beginning 21 August. Planned topics include data center design, energy metrics, and perspectives from both IT and facilities specialists. You can see an 3 minute preview on YouTube now, then register for the full 60 minute version. Cisco has invited me to preview the full program; I'll add my review as a comment to this post as soon as I do.
