Natural Gas Savings, Traps, and H Vacs

By Energy Rant One Comment
I flipped open AESP’s annual magazine to pick up a topic for this week. I chose the last article on natural gas programs. I’ve always found it interesting that folks perceive natural gas to be an enigma for finding savings. If natural gas is being used, the potential for savings is not more difficult to find than electricity savings. Steam “Traps” Let’s start with steam traps. Programs that maintain and replace steam traps are akin to electric programs that fix compressed air leaks.Traps capture things, right? Mousetrap. Ant trap. Beartrap. Ackbar trap. However, a steam trap doesn’t trap steam. It…

Energy Efficiency in a Land of Renewable Foie Gras

By Energy Rant No Comments
A couple weeks ago in Renewable Energy, Bad Parents, and Strawberries, I wrote that the value of an electrical generating resource depends a little on how cheaply it can produce energy (kWh), but a LOT on when and the (new word alert) dispatchability of the resource. For instance, California already has so much solar generation at the wrong time of day that it needs to dump kWh by paying producers to quit. This is demand response in reverse, or (new term alert) supply response. Yes, they are curtailing less than 1% of sales, but they are also two years ahead…

Investor Confidence Project – Inoculation Against Hucksters

By Energy Rant One Comment
Led by the Environmental Defense Fund, the Investor Confidence Project (ICP) provides a platform of quality assurance checks and balances for energy efficiency project developers, quality assurance providers, investors (lending companies), and building owners. It could be the greatest mechanism for deep and wide energy savings since the T8 light bulb. I was first introduced to the Investor Confidence Project as I was reviewing abstracts for AESP’s 2016 Spring Conference in Philadelphia. The following snippets are from the abstract summary. There are many investors and tons of capital waiting to be poured into energy efficiency projects. The problem is that…

Program Adoption Curves – Telephones and Televisions

By Energy Rant No Comments
There are certain energy efficiency programs that we are never going to pursue – all those that are in the late majority and laggard stages. Those ships left the pier 10-15 years ago, and we are not going to attempt to catch them. In two words, they are widget programs, up, down, mid, over, under-stream programs of all stripes, including direct install. The previous chart shows theoretical adoption and market share curves. Of course, in reality, adoption isn’t nearly as pretty, as shown in the next chart, which is fascinating. You will want to get your own version of that…
