GreenTouch, the global consortium dedicated to dramatically improving the energy efficiency of data and communications networks, announced May 13 the findings of a new research study that shows the net energy consumption in overall networks can be reduced substantially—up to 90 percent—by 2020. This first-of-its-kind study evaluated energy efficiencies in different types of networks, comparing those in 2010 with those incorporating the technologies and architectures the consortium has identified that could be in use by 2020. Findings included the potential to reduce energy consumption within mobile networks by 1043 times, fixed access networks by 449 times and the core network by 95 times.

The Bentley -- a Continental GTC convertible starting at $191,000 -- became the center of attention throughout most of the week as thousands of geeks filed through the Las Vegas Convention Center's North Hall."
