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 Art and Craft

Green ICT is serious business, but it does not have to be solemn. We periodically take a look at the humorous and the quirky and, in this post, Green ICT-themed art and crafts. The most recent pieces are e-waste craft projects.

Mega Data Centers

We've been tracking the growth in mega-datacenters since 2009. These faculties feature technical and operational innovation that has overturned previous notions of limits on energy efficiency. But does the focus on efficiency obscure an acceleration in ICT energy and water consumption and in CO2e production? While mega-data center operators are claiming exceptional power usage effectiveness (PUE) ratios, we're still talking about facilities that consume 20-200 MW apiece and emit a considerable carbon footprint unless powered by renewable energy. Here's our most look recent mega-datacenter issues, including new statistics that suggest the mega-datacenter boom will cause a decrease in the total number of facilities.

E-Waste Goes A Long Way Back

An incident thirty-one years ago illustrates that e-waste is not a new problem. Atari had to dispose of millions of unsold cartridges of Pac-Man, E.T., and other games . Here's what the company supposedly did back then and how various efforts are are elevating the dump site to mythic status. I thought my final update was last April, but I'm back on it again- this is a story that will not die!

Here is a video announcing the April 2014 uncovering of Atari's long-buried e-waste. Check that out, then read on to see what happened next.

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.

More Efficient Supercomputers

Tianhe-2 Chinese SupercomputerSupercomputer manufacturers have always vied to build the most powerful machine. Recently, they have sought to increase energy efficiency, as well. Yet innovation appears to be slowing. The most recent ranking still shows the top performer to be China's Tianhe-2, a position it obtained in June 2013. (Tianhe translates as "Milky Way" in English.) An american supercomputer installed in Switzerland is the most energy-effieicnt of the Top 10 machines.

Most Printer Cartridges Still Not Recycled

Workplace social site Cafe Quill has published GreenHab the Office infogrpahic (below). It has many good practices; we're were particularly glad to be reminded of one of the more mundane but still important aspects of Green ICT. And the reminder came with a shocking statistic!

The Scope of eWaste in Latin America

GSMA has published a report and a couple of infographics about e-waste in Latin America. The infographics are displayed in full, below. This report is sign of growing Green CT awareness in the region.

The full report - GSMA's May 2014 report "eWaste en América Latina- is published in spanish, but an executive summary and one of the inforgraphics is available in english. Here are some highlights.
