Think mobile devices are low-power? A study by the Center for Energy-Efficient Telecommunications—a joint effort between AT&T’s Bell Labs and the University of Melbourne in Australia—finds that wireless networking infrastructure worldwide accounts for 10 times more power consumption than data centers worldwide. In total, it is responsible for 90 percent of the power usage by cloud infrastructure. And that consumption is growing fast.

What is the digital equivalent of public transport?

The study was in part a rebuttal to a Greenpeace report that focused on the power consumption of data centers. “The energy consumption of wireless access dominates data center consumption by a significant margin,” the authors of the CEET study wrote. One of the findings of the CEET researchers was that wired networks and data-center based applications could actually reduce overall computing energy consumption by allowing for less powerful client devices.

According to the CEET study, by 2015, wireless “cloud” infrastructure will consume as much as 43 terawatt-hours of electricity worldwide while generating 30 megatons of carbon dioxide. That’s the equivalent of 4.9 million automobiles worth of carbon emissions. This projected power consumption is a 460 percent increase from the 9.2 TWh consumed by wireless infrastructure in 2012.

So, time to walk the talk Green boys and girls.  Ditch those carbon sucking devices now.

As much at home writing editorials as being the subject of them, Cam has won awards, including the Canon Media Award for his work on the Len Brown/Bevan Chuang story. When he’s not creating the news, he tends to be in it, with protagonists using the courts, media and social media to deliver financial as well as death threats.

They say that news is something that someone, somewhere, wants kept quiet. Cam Slater doesn’t do quiet and, as a result, he is a polarising, controversial but highly effective journalist who takes no prisoners.

He is fearless in his pursuit of a story.

Love him or loathe him, you can’t ignore him.
