I hate electricity. I love what it allows me to do but I just don’t understand it. I sat through an in-house safety training session on arc flash, which I actually understood – there is a huge burst of energy through a “fault” that melts and actually vaporizes the copper conductor, which expands 7,000 times at Mach 2 and 1 million degrees F (made up numbers but the premise is correct). It’s one heck of an explosion. During a break I was asking our electrical engineers what the difference between a neutral and ground was, the flow of electrons, the…

There is a running joke in our business that electrical engineers don’t know anything about energy efficiency. It is only a joke. One of the sharpest energy guys I have interviewed was a physics major who started on the ground floor of an energy efficiency consulting firm filling orders of equipment they also happened to sell. In 10 years he worked his way up to really understanding how buildings and their complex systems work and he became a manager of a team of energy engineers teaching his group how buildings work and how to model them. This article made laugh…
