Interesting, 2 years later, another GreenTouch article "Bell Labs group aims at 90% energy-saving in networks" talks about energy savings. Actually they're dreaming about much more than the headline suggests since they're seeking to reduce total energy use by 90% WHILE usage grows by 10 times. However, so far it seems the primary product is public relations. What has been done on the energy savings front to impress the engineering community?
Joining a "green" consortium makes a "feel good" news headline for each member as they join. The real news, however, will be in what they accomplish. Perhaps such consortia should require that tangible evidence be provided of the benefits provided by members before they're permitted to reap the public relations benefits of joining. The work hasn't started yet.
