Green-certified computer displays are now too numerous to present in table format. Here is how to find the most sustainable displays, including projectors, listed by two certification services.
Four manufactures offer over 150 EPEAT Gold models in the United States. This is a significant improvement over a year ago. Lanier and Savin now offer EPEAT Gold models and both top the list with most models, closely followed by Konica/Minolta. Epson appears to no longer offer EPEAT Gold models.
The EPEAT Gold database includes 389 models for the US. This represents a drop of ~30% over a year ago. The biggest drops came from Toshiba (-47%) and Samsung (-76%), the companies that offer the most models a year ago. Toshiba is still a model count leader, along with HP and Apple. The latter two companies increased their models counts in the past year.
ICT gear depends on materials whose supply is increasingly affected by environmental and political factors. This gives rise to a complex set of issues ranging from resource scarcity to conflict minerals.
ICT facilities are becoming increasingly innovative in reusing their waste heat, a trend we first identified in 2009. This has been strongest in Europe, where many municipalities have district heating infrastructures into which facilities can transfer excess heat. Our latest example, from Switzerland, is just this sort of arrangement.
We have been tracking this topic the inception of Vertatique and it is consistently our most-Googled post. We just updated it to better present the material and add newer information.
Dematerialization refers to the reduction in the quantity of materials required to accomplish a function in society. In sustainability terms, dematerialization refers to the replacement of a high-resource/waste activity with a lower-impact one. ICT has become a powerful dematerialization force, evidenced, for example, by how it has replaced physical mail with electronic mail. The US theatrical release of a major motion picture only in digital marks another phase in media dematerialization.
We documented how the e-waste America ships overseas returns to threaten it's citizen's health. Now, we've learned how that e-waste also threatens America's national security.
Cloud computing has the potential to significantly advance Green ICT. Cloud computing can be greener than in-house data centers for many small and medium companies. Yet many of the wasteful practices that result in unnecessary resource consumption and toxic emissions in traditional ICT are now finding there way into cloud utilization.
A 2010 version of this post was titled "No One Can Agree on Typical PUE". I wrote, "As more data centers measure their PUE, managers ask what is typical? The industry does not seem to agree, so a wide range of numbers is out there." I updated the post in 2012 with the latest data, concluding that most data centers still appear to be operating above a PUE of 2.0."
I put the question to Vertatique's global Green ICT community in August 2013 via a tweet: "After years of #GreenICT, is there evidence that most #datacenters now operate below PUE 2.0?". This was one of our most-retweeted, but no one came forward with new evidence. Some replied in the emphatic negative.
Three years of very enlightening survey results from Digital Realty, including the 2014 data, confirm that the 2012 analysis. The only lower (better) average PUE came from Microsoft.
