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.
Green-certified computer displays are now too numerous to present in table format. Here is how to find the most sustainable displays, including projectors, listed by two certification services.
Four manufactures offer over 150 EPEAT Gold models in the United States. This is a significant improvement over a year ago. Lanier and Savin now offer EPEAT Gold models and both top the list with most models, closely followed by Konica/Minolta. Epson appears to no longer offer EPEAT Gold models.
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.
Model counts are an imperfect way of tracking progress, but these are big swings. It is not clear why there has been such a drop in EPEAT Gold notebooks. It could be as simple as product line rationalization or as complicated as the lobbying effort against EPEAT purchasing. The incorporation of stronger Energy Star standards in 2014 may also have down-rated models that were formally Gold.
The number of models TCO offered under Sweden's TCO Development standards increased 43% over the same period to 120 models. ASUS and MLS registered their first products during this period. Lenovo and Samsung offer the most models, as they did last year. There was no decline in Samsung's TCO models as there was for its EPEAT models.
ICT gear depends on materials whose supply is increasingly affected by environmental and political factors. This gives rise to a complex set of issues ranging from resource scarcity to conflict minerals.
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.
