Amid the hullabaloo over government-chartered mortgage giants derailing the green financing program known as Property Assessed Clean Energy, or PACE, the march toward distributed generation of renewable energy – that is, generating electricity from...[read more]

A smart electric network – in more ways than one

June 29, 2010 by Rich Maltzman

As we often do here on EarthPM, we are going to combine a couple of pertinent and important themes to hopefully strengthen some points that are key to each of them. The two themes we relate here are: Electric Smart Grids for effective power transmission and reduced carbon footprint High-powered Grids of Smart PMs to gain a bigger...[read more]
