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:

Conversion to renewable energy: on-site solar

Use of virtualization to reduce 4 servers to 2: 38% reduction in server energy consumption*

Implementation of more sustainable printing technologies and practices

Increased use of online communications tools to reduce travel

Vibiano's "360 Green" site - Microsoft Case Study

* Vertatique tries to make the extra effort to track news reports back to source material to insure the most accurate information possible. This post is a good case in point in how difficult it can be to reconcile information from multiple sources.

I originally heard about the Vibiano case study from a tweet linking to a 'Reuters' article that said "Using...virtualization..., Monte Vibiano was able to cut the number of servers in use by half, and reduce the energy used by the remaining servers by 38 percent." A reader could interpret this as a ~88% energy savings: ~50% from a server count reduction of 50% and 38% on the remaining two servers. That would be an extraordinary accomplishment for virtualization of a 4-server installation, yet neither the Vibiano nor the Microsoft sources I tracked down and cited above reference a higher total savings or explicitly assigns the 38% savings to the "remaining" servers.

Turns out that article was not original Reuters work: Reuters sourced the article from greenbiz.com, which in turn sourced it from an affiliate site. I chose to go with my more conservative interpretation of the source material, but would appreciate clarification from anyone involved.

Update:
I have received preliminary confirmation from a source close to the original case study that 38% does, in fact, represent the total energy reduction.
