that sweet "I TOLD YOU SO" moment has arrived...,

WaPo | Ralph Izzo, the chief executive of the New Jersey’s Public Service Electric and Gas Co., isn’t your average utility executive.

At Columbia University, he studied mechanical engineering as an undergraduate and later earned a doctorate in applied physics. At the Princeton Plasma Physics Laboratory, he did numerical simulations of fusion experiments and published or presented 35 papers on something called “magnetohydrodynamic modeling.”

So it’s not surprising he would say that he “fell in love” in 1998 with the gadgetry commonly known as “smart grid” technology — as Izzo puts it, “customer communication technology, real-time price signals and fantastic sensory capability.”

But 13 years later, Izzo says, “I have only now come to realize that what I really wish my customers would do would be to use more caulking.”

The smart grid has been one of the most talked-about issues in energy policy. Experts — and manufacturers of equipment and software — have promoted the idea that “smart meters” could enable utilities to flip household appliances on and off to ease the load of summertime electricity demand and that the devices would help homeowners manage their refrigerators, lights and air conditioning, even controlling them remotely with cellphones, laptops or tablets. Smart grid technology is also seen as critical for integrating renewable energy sources onto grids designed to carry power one way only, from big clunky generating stations to the home.

All this depends on software, networking devices and smart meters, tens of millions of which have been installed across the country. If the grid is modern society’s central nervous system, then the smart meter could become the brains of the operation.

Yet many utilities have come to the conclusion Izzo has: You can install smart meters in homes, but the homes probably still have dumb appliances and homeowners who are too busy to be bothered. At least for now, simple measures such as caulking might save more energy.

“Somehow all of us collectively decided to skip the low-hanging fruit and go for the top of the tree,” he said at a recent energy conference sponsored by The Washington Post.
