(Hosting-NewsWire.com, April 13, 2013 ) London, UK -- A new study by the Center of Energy-Efficient Telecommunications, which is a joint effort between AT&T Bell labs and the University of Melbourne, Australia, found that wireless networking infrastructures across the globe account for 10 times the power consumption as data centers worldwide.
All told, such networks are responsible for 90% of the power usage by the cloud infrastructure, and that consumption seems to be growing fast.
The study was all part of a rebuttal to Greenpeace's report that focused directly on 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 from the CEET researchers was the notation that wired networks and data-center applications can actually reduce the overall energy consumption taken up by computers. They do so by allowing less powerful client devices to function.
According to the CEET, within the next three years, the wireless “cloud” infrastructure will likely consume as much as 43 terawatt-hours of electricity across the world, while generating nearly 30 megatonnes of carbon dioxide. That total is 4.9 million automobiles worth of carbon emissions, according to the CEET. The projected power consumption is a nearly 460% increase from the 9.2 terawatt-hours that were consumed by the wireless infrastructure in 2012.
Such growth projected by the CEET has been based upon the scenario wherein such networks reach two billion users worldwide by 2015, and generate traffic of 4.3 exabytes per month.
There are more conservative estimates of 32 terawatt-hours utilized by “low-uptake” scenarios for wireless broadband services, with only 1.6 billion users across the globe. The figures have included users who accessed the cloud through in-home, as well as public, WI-FI and femtocell and carriers' cellular infrastructure alike.
