Soaked to Crisp Threats and 100% Renewable Energy

By Energy Rant No Comments
Last week I attended the International Energy Program Evaluation Conference, IEPEC, which I had affectionately dubbed the Energy Program Evaluation Asylum, EPEA, six years ago. Back then, I called it the Asylum because it included annual scrums over subjects such as net-to-gross (NTG) studies, free ridership, and so on. The Family Feud is Dead You’ll never believe this, but the industry seems to have moved on. The only time I heard “NTG” was during the opening-night entertainment exercise – a gameshow wannabee modeled after the Family Feud. “One hundred evaluators were surveyed.

Grid Power Generation – Stories Untold

By Energy Rant 2 Comments
Most of you reading this owe your lives to the phenomenon described in this post. Therefore, it is worth understanding precisely how grid power is generated, and what it looks like. And of course, you will not find this anywhere else. Rant topics are inspired by reader comments. At AESP National, a young gentleman approached me to say the Rant provides good information that is easy to understand and read. He referenced a Greentech Media Energy Gang podcast, which explained as much. At the ~50 minute mark of the podcast, they explain that learning how things work, and being able…
