Microsoft to Release Free Software Estimating Virtual Machine Energy Use

Understanding the energy consumption of a particular piece of software, such as a web site like Vertatique running in a virtualized environment, has been a difficult undertaking. Now, Microsoft Research is introducing Joulemeter, "a software based mechanism to measure the energy usage of virtual machines (VMs), servers, desktops, laptops, and even individual softwares running on a computer…Joulemeter can be used for gaining visibility into energy use and for making several power management and provisioning decisions in data centers, client computing, and software design."

Big Difference in Recycling Lithium Batteries

Lithium batteries are showing up in everything from personal e-gear to communications backup systems to next-gen electric cars. Will they become the next e-waste? And do you know the important distinction between recycling Li and Li-ion technology?

How Much Heat Does a Server Generate?

How much heat does a server - or any other piece of ICT gear - generate? Here is how you can calculate it.

Cloud Computing Starting to Follow the Sun-Wind-Moon

"Follow-the-sun"*, "follow-the-wind", "follow-the-moon" and "follow-the-kilowatt" are cloud computing operational strategies that dynamically shift processing around the global to balance demand proximity with low energy prices. While much of the discussion has been theoretical and speculative, we are starting to see implementation.

Keeping It Real is the Path to Success

The CIO Executive Board has identified what it calls "two critical activities to successfully sustain green IT projects." These tie to our "Keeping It Real" criteria, which are critical to long-term credibility of any green initiative.

Sweating Our Assets in a CapexLite World

The greenest purchase is often no purchase at all. Many items will have made much of their life-cycle energy/carbon impact by the time they hit our loading docks. "Sweating our assets" refers to getting more productivity and longer lifecycles out of what we already have, an even more critical skill now that access to cheap capital has diminished. There are two GreenICT reasons for doing this.

Carbon Footprints of Servers Can Vary By 10X

What is the carbon footprint of a server? It turns out that the answer can vary by a factor of 10x, depending on three key factors.

Europe is Beating Swords into Green Data Centers

Repurposing military facilities into green data centers appears to be a growing trend in Europe. We recently noted a Swiss data center built in an old military bunker and an Icelandic facility in a decommissioned NATO base. Now Sweden offers another variation on this theme: an underground data center with a Cold War pedigree.

Green ICT Book Reviews

We've identified over a dozen books on Green ICT topics. Which are right for you? Surprisingly, most aren't reviewed outside of bookseller sites. We're researching industry sites and plan to post a new review each time we discover one. (Updated 2009.09.20)

Italian Wine, Green ICT, and Accurate Information

Mega data centers are capturing much Green ICT press these days, so it is useful to remember that more modest enterprises can benefit as well. Monte Vibiano is a family-owned wine and olive oil producer that is taking an aggressive approach to Green ICT. Vibiano's actions include:
