Green ICT in Europe: Too Many Local Standards Listing Too Few Products

We found back in 2010 that the European market for Green ICT products had many local standards with few certified products. That did not appear to best serve sustainability-oriented computer buyers - consumer or enterprise - who need to make practical purchasing decisions incorporating sustainability. The situation has not improved in recent years.

Our recent update of Finding the Greenest Tablets illustrates the continuing challenges for conscientious buyers trying to sort through standards.

Finding the Greenest Tablets

I reported in 2014 that I could find only one green certification program for tablets. The situation is a lot better today, with eight manufacturers offering top-ranked products.

Europe Leads Green IT Conferences

The number of Green ICT conferences and workshops rebounded in 2016 after slumping the previous year. Europe continues to host more events than do other regions.

Green ICT Progress in Higher Education

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 -- the latest looks at an American University's attempt to make an impact on student e-waste.

Innovative Ways We Could Be Recharging Our Devices

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.)

Who Creates the Most E-Waste?

Free Air, Hot Racks, and Cool Liquids

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.

Will Liquid-Cooled Computers Make a Comeback?

Liquid cooling was once a staple of large-scale computing, but has largely been replaced by air cooling.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.

Finding the Greenest Notebooks

The EPEAT Gold database includes 389 models for the US. This represents a drop of ~30% over a year ago. The biggest drops came from Toshiba (-47%) and Samsung (-76%), the companies that offer the most models a year ago. Toshiba is still a model count leader, along with HP and Apple. The latter two companies increased their models counts in the past year.
