Companies and individuals are advancing innovative ideas with potential for mainstream Green ICT. These range from products and services available today to futuristic concepts for tomorrow. Our latest are mobile devices powered by plants and greener computer mouse.
Handling our gear's heat has always been an issue for installations large and small. ICT equipment typical took 1x-2x again more energy to remove its heat as it took to power it in the first place (PUE of 2.0+), driving both energy costs and carbon footprints. Early efforts focused on the two obvious tactics: make both the ICT gear and the air conditioning more efficient. We now see these augmented by innovative new approaches to the problem, ranging from seawater cooling to variable-speed fan retrofits.
Upcoming Green ICT conferences and workshops around the world. We just added a 2015 event in Nassau, The Bahamas.
We have also included links to past conferences to aid your search for Green ICT materials.
Quiz: Which region has the most Green ICT conferences?
Liquid cooling was once a staple of large-scale computing, but has largely been replaced by air cooling.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.

We haven't given much thought lately to calculators, as this function built into most feature phones and all smartphones. German eco-certifier Blue Angel does think about them and has certified 16 models of solar-power calculators from Casio, Citizen, Dieter, Moravia, Staples, and Texas Instruments. Blue Angel cites these models for "use of renewable energies, high level of serviceability, reduced use of contaminant-containing batteries."
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.
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.
