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. See much more by clicking on the "Green media" tag, above.
Green-certified computer displays are now too numerous to list in table format. Here is how to find the most sustainable products listed by two certification services.
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 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.
We launched Vertatique with the statistic that data centers consumes ~2% of global electricity production. We now know that the globe's broader ICT energy footprint is ~8%, the majority of which is NOT from data centers. The contribution of communications, driven by explosion of cloud computing and mobile devices, has helped drive the number higher. Here are the facts and figures.
We've noted that there has been too little focus on Green ICT in American higher education. This does not mean that colleges and universities in American and around the global aren't making any progress at all - you can click on the 'education' tag above to see examples. We regularly add updates about global higher education in this post -- we just took a look at Green ICT in a UK award program.
Traditional ICT facilities consume as much energy cooling their gear as powering it the first place. One solution is to re-use the waste heat. Our latest example is shows that even a small data center can re-use heat.

Norway's Fjord IT is another example of ICT facilities looking to local climate to boost sustainability. The company cites "...the cold and stable climate in Norway, development of a passive cooling solution, hydro-power.." as location-specific advantages. Combined with energy-efficient gear, the company claims this "...allows us to operate with close to zero carbon footprint...and a Power Usage Effectiveness (PUE) lower than 1.05." Fjord IT's partner Pivotal adds that appreciation for Norway's advantages "...led [Fjord IT CEO Helge] Gallefoss to patent a passive cooling technology that reduces power usage by as much as 50% [and to utilize] Norway’s power grid [which] produces 99% of its energy from hydropower..."
We estimate that in 2014 that 19 billion devices were attached to our global ICT infrastructure. We recently saw an estimate of 50 billion for 2020. What would the path to 50 billion connected devices look like?
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'll regularly update this post with technologies to watch. (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 multiferroic materials to reduce device waste heat to new software to make cloud computing more efficient. (And don't miss research into using human urine to power a mobile device.)
