Researchers around the global are exploring innovative ways to sustainably recharge the billions of edge devices attached to the global ICT infrastructure. Experiments use everything from plants to urine . (You may have to reload page to display videos.)

The data center community has been very focused on reducing energy cost with "free cooling" - disposing of waste heat using natural cooling sources such as cold air and cold water. Even use of seasonal ice for datacenter cooling has been considered! Now, an article from Brazil offers a a unique perspective on a bias implicit in this focus.
The number of Green ICT conferences and workshops declined in 2015 to the lowest level in three years. Europe continues to host the more events than do other regions.
The original directory of upcoming and past Green IT conferences is now the Green ICT Conference Directory. We did this because of the increasing number that include or focus on sustainability in communications - the "C" in Green ICT
Electronic media infrastructures and gear are important components of global ICT as movies, television, music, and books all go digital. This post offers a global sampling of sustainability in e-media. A green production app is our latest find.

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 include a data center in Washington state the touts both green power and seismic safety, Apple benefiting from its Nevada (US) site's underground water and low risk of natural disasters, an award-winning Norwegian data center benefiting from on-site hydro and cooling water, and a video about Iceland.
The search for the greenest TVs continues to be challanging. EPEAT added televisions to its equipment registry in early 2013. We had anticipated this would bring some clarity to this category. There were significantly less Gold-registered televisions April 2014, compared with computer monitors, but we saw that to be a good start. We were wrong.
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.
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.
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.
