Location is becoming increasingly important to the sustainability of ICT facilities. We've been tracking facilities in North American and Europe which try to leverage geographic features for greener operations. Our latest examples in the North America section of this post show how under-utilzed grid power is also making some locations attractive.
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.
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 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.
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.
Here are our most popular 2014 tweets, according to Twitter Analytics' 'engagements' metric. Click on any one to get the story behind the tweet.
We are a USA-based initiative, so we publish in English. There is a growing wealth of Green ICT material in other languages. This is a directory of the references on Vertatique to non-english resources.
There is a rich global mix of advanced concepts and technologies emerging from research labs that may improve the future sustainability of ICT equipment and infrastructures. We regularly update this post with technologies of interest. (You can see all the technologies which hold the promise of greener ICT in the future by clicking the 'FutureTech' tag, above.) Our latest posts span research into biological agents that can recover gold from e-waste to multiferroic materials to reduce device waste heat.
Government entities have an important role to play in encouraging sustainable ICT across all industries. Effective leadership requires internal implementation, as well. The tag at the top of this post - government - helps you easily locate posts containing opportunities for and applications of Green ICT in government operations. (Green ICT in public education is found through the education tag.) Our latest update to this post is the disappointing news about New Zealand's decline in ICT sustainability in government.
The creation of ICT content - software and e-media - is part of ICT's footprint of resource input and waste output. A 2009 UK report, while dated, is still helpful in scoping the size and structure of media industry footprints.
