ICT facilities are becoming increasingly innovative in reusing their waste heat, a trend we first identified in 2009. This has been strongest in Europe, where many municipalities have district heating infrastructures into which facilities can transfer excess heat. Our latest example, from Switzerland, is just this sort of arrangement.
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.
We have been tracking this topic the inception of Vertatique and it is consistently our most-Googles post. We just updated it to better present the material and add newer information..
Companies and individuals are advancing innovative ideas for more sustainable products. These range from products and services available today to futuristic concepts for tomorrow. Our latest are an Ebola-proof tablet and a computer built with 100% recycled plastic.
Dematerialization refers to the reduction in the quantity of materials required to accomplish a function in society. In sustainability terms, dematerialization refers to the replacement of a high-resource/waste activity with a lower-impact one. ICT has become a powerful dematerialization force, evidenced, for example, by how it has replaced physical mail with electronic mail. The US theatrical release of a major motion picture only in digital marks another phase in media dematerialization.

UK-based BSI group is hosting the documents for a new standards series - ISO/IEC I 30134 - for data center performance. One standard centers around the well-known PUE metric. Another proposes a renewable energy factor (REF). We inspected the REF document, but found little useful information about what an REF standard might look like.
Upcoming Green ICT conferences and workshops around the world. We just added a 2015 event in Split, Croatia
We have also included links to past conferences to aid your search for Green ICT materials.

We documented how the e-waste America ships overseas returns to threaten it's citizen's health. Now, we've learned how that e-waste also threatens America's national security.
Cloud computing has the potential to significantly advance Green ICT. Cloud computing can be greener than in-house data centers for many small and medium companies. Yet many of the wasteful practices that result in unnecessary resource consumption and toxic emissions in traditional ICT are now finding there way into cloud utilization.
