Liquid cooling was once a staple of large-scale computing, but has largely been replaced by air cooling. We identified several efforts to bring liquid cooling to the server world in our first version of this post in 2012 and have seen continuous progress since. Here is the latest news.

A benefit of speaking at a conference, as I did last month as a GSICT keynoter, is learning from the other speakers. One presentation made me aware of Green ICT work underway through the Digital Agenda for Europe.
Task 4, last updated in April 2015 is described as a "50 partner cluster" spanning "6 FP7 Projects from the Call on Data Centres Sustainability: DC4Cities, RenewIT, Dolfin, GENiC, GEYSER & GreenDataNet, aiming to increase renewable energies use, heat reuse and the utilization of Smart Grids; 2 projects from a previous FP7 Call : All4Green, CoolEmAll; one H2020 project on public procurement of sustainable data centres (EURECA)."
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.
Our e-devices contain all sorts of exotic materials, many of which, like tungsten, tantalum, and tin, are refined from ores that originate in Central Africa. Called "conflict minerals", they fund warfare in the Congo and neighboring countries. More people are said have been killed here than any conflict since World War Two. Progress is being made, but legal setbacks and weak laws are slowing efforts. The latest critiicisms focus on proposed EU regulations.
were critical of Apple's environmental stance a few years ago, saying that the company was positioned to be a leader rather than a a foot-dragger. Since then, the company has made significant strides, such as improvements to its take-back recycling programs*. On the downside, issues about its Chinese contract manufacturing operations have been slow to be resolved. Recent actions toward addressing labor issues need to be matched with ones addressing environmental issues. Factory pollution takes a toll on both workers and neighbors and a July 2013 report alleges problems still persist. Yet Apple continues to improve its environmental position in China - producing solar power is its latest initative.
Eleven manufacturers are offering over 230 models of desktop computers in the EPEAT USA Gold database, about the same number as a year ago. Dell, HP, Lenovo, and Apple offer the most choices.
Sweden's TCO Development certified 32 products, down from a high of 80. Most manufacturers appear to have dropped out of TCO certification in this category; only Hewlett Packard and Lenovo now participate.
Germany's Blue Angel only lists models from Fujitsu.
Acer/Gateway and Phillips no longer offer qualifying models and have been removed from the list. Wyse is new to the list this year.
"E-waste" and "cyber waste" describe the unwanted systems and components of our industry. Green organizations and facilities mitigate their e-waste impacts by repurposing and recycling equipment when scheduled for replacement. Despite all the focus on e-waste over the past decade, it continues to pollute communities around the world and threatens global ICT infrastructures. Yet no one cal agree on how much is actually out there.
Twelve manufacturers offer ENERGY STAR® qualified servers, down from seventeen in 2013. Symantec and Unify are the latest to offer products. Energy consumption is only one criteria for choosing the greenest server, but there are no comprehensive ratings of green servers.
