back to article IT and comms power consumption could surge in 2013

An Italian researcher has predicted that the global Internet's power demands will surge by 19 percent during 2013, compared to 2012 – and that over time, such ballooning electricity demand will become unsustainable. In a paper published in Science last week (abstract), University of Catania researcher Diego Reforgiato urges more …
