Green data center

Energy Cost per Square Foot

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"

EPA Report a Wealth of Green ICT Statistics

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 . . .

Naked Emperors and Straw Dogs

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.

More on Computing's Contribution to Telework

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:

Green ICT Videos

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.

Where to look first for data center efficiency

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.

Climate Savers' Software Tools for Green Computing

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.

Webinar: Energy Efficiency in the Data Center

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.

EPA Report

The EPA Report to Congress on Server and Data Center Energy Efficiency found that "The peak load on the power grid from these servers and data centers is currently estimated to be approximately 7 gigawatts (GW), equivalent to the output of about 15 baseload power plants and "power failures and limits on power availability will interrupt data center operations at more than 90 percent of all companies over the next five years." This was written in August 2007:

A Wealth of Data Center Data

The McKinsey / Uptime Institute report Revolutionizing Data Center Efficiency, available as both a PowerPoint and a podcast, contains a wealth of current and projected data on energy utilization and GHG (greenhouse gas) emissions, including information about what various enterprises are doing. Among its findings:
