We took a trip over to Eaton Corp.’s Power Systems Experience Center near Pittsburgh to see a demonstration of a type of gizmo being promoted as able to boost energy efficiency. These devices generally consist of little more than a capacitor mounted across the ac line. They do impact the power factor of inductive loads such as motors, but they don’t result in any energy savings, as explained in the video by Center manager Dan Carnovale.
We also wrote about the Center’s work on energy efficiency scams in our 2015 Energy Efficiency Handbook.
