Mobile devices replace the storage capacity and I/O options laptops with a host of cloud services. We first saw this when iPhone users began placing unprecedented demands on the cloud in 2009. Statistics compiled since then reveal the the amazing growth and scope of this demand. This only increases the urgency for cloud providers go green.
Equipment and cooling are the two big targets for reducing energy consumption in ICT facilities. Operators who really want to drive PUE have to look at all areas of consumption and facility lighting is no exception. Lighting consumes energy directly and produces ambient heat that also increases the cooling load. Here's a look at what facility designers and operators are doing.
Looking for the greenest television set? We've had to sort through a complex set of resources in the past to help you buy that green TV. EPEAT added televisions to its equipment registry in early 2013. We had anticipated this would bring some clarity to this category, but manufacturers do not appear to be embracing it. There are only 240+ television monitors registered at any level, double the number in early 2014. This compares with 660+ computer monitors.
Four manufactures offer almost 70 EPEAT Gold models in the United States. This is a huge improvement over a year ago.
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. A recent court decision has potentially weakened an American law requiring companies to disclose conflict minerals content.
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.
New ICT facilities implementing the latest in Green ICT technologies and practices garner much publicity, yet a lot is being done with existing ones. The latest post looks at what a major financial services company accomplished through interdepartmental cooperation.
We've covered technology to reduce paper use when printing. What about reducing ink use? A high school student's study found that his school could save $21,000/year by switching typefaces...and the United States government could save $234 million!
We've been following the issue of conflict minerals in our e-devices for more than five years. Our readers will know that cassiterite, the mineral ore form of tin, is a conflict mineral when mined in Central Africa. It turns out that much more tin - over a third of the world's consumption - is mined in Indonesia. Tin extraction there is not driven by conflict, but is still a brutal business for the miners and takes a toll on the environment.
