Is PUE Still Above 2.0 for Most Data Centers?

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.

Green ICT Resources in Many Languages

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.

Technologies for the Future of Green ICT

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.

Media Production's Footprint

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.

The "C" in ICT is Driving Global Energy Consumption

We launched Vertatique with the statistic that data centers consumes ~2% of global electricity production. We now know that the globe's broader ICT energy footprint is ~8%, the majority of which is NOT from data centers. The contribution of communications, driven by explosion of cloud computing and mobile devices, has helped drive the number higher. Here are the facts and figures.

50 Billion Connected Devices by 2020?

We estimate that in 2014 that 19 billion devices were attached to our global ICT infrastructure. We recently saw an estimate of 50 billion for 2020. What would the path to 50 billion connected devices look like?

Data Centers Not Largest Locus of ICT Energy or Emissions

Most Green ICT attention focuses on the datacenter. Five years of work consistently holds that datacenters represent a minority of total ICT energy consumption and carbon emissions.

Diverse Winners of Green Mobile Awards

GSMA's Global Mobile Awards' Green Mobile Awards are for "mobile industry organisations that are focused on the reduction of environmental impacts through eco-friendly, innovative policies, products, programmes or initiatives, as well as organisations outside of the industry that utilise the mobile platform to communicate, innovate or drive eco-friendly programmes, services and initiatives." Here's a look at the 2009-2013 winners and at the trend toward greener mobile base stations.

Gartner's Vanishing Green ICT Awards

Gartner, the ICT research and advisory company, got off to an early start in Green ICT recognition with two events in 2010. Since then, the organization appears to have dropped its focus on recognizing sustainable ICT.
