Energy Rant

This is a satirical and at times humorous but critical commentary on energy efficiency issues of the day.

“Keep up the good work! I like the variety of topics; never boring. It's like a Box of Energy Chocolates.... you never know what you're gonna get!”

Demand Management for Good

By Energy Rant No Comments
The last few posts featured an overview and complete report card on load management to get beyond net zero to real zero, a term I discovered last week. As promised, I will describe some permanent peak load reduction opportunities this week. Like many efficiency solutions, blocking and tackling approaches are the most effective. Peak Load Reduction – New Construction I’m going to stick with some big hitters. A person could write forever on this topic. Home Envelope Single-family homes must be super-insulated to minimize heating loads in cool/cold climates. The cartoon below provides a nice example of super-insulated versus code…

A Ten-Dimensional Demand Response Examination

By Energy Rant No Comments
This is the third installment of this series in demand response (DR) and load management. In the first post, Curing Net Zero described why net zero is not the answer: everyone over-generates with solar or wind simultaneously, and later, everyone needs power from something else simultaneously. The second post, Demand Response Primer, gave an overview of families and specific types of load management. This time we’re looking at my scorecard of these DR resources. Here is my report card, including critical factors for each DR resource, followed by discussions of what it means. What does this poppycock mean, Jeff? Peak…

Demand Response Primer

By Energy Rant No Comments
Last week I described how net zero sounds grand, it’s easy to do, but it doesn’t work to support the transition to a clean-energy grid. The reason is that everyone, whether utilities or customers, overproduces simultaneously, and then later, customers all need energy from thermal power plants simultaneously. We have an exploding deficit of customers to take that overproduction and shift load or store it for use when intermittent renewable supplies shut down. In Renewables at Scale, I described how renewable supply and batteries would never be sufficient. The gaps in intermittent renewable supply are too big for batteries to…

Cure Net Zero with Demand Response

By Energy Rant No Comments
I lambasted net zero many times, one time calling it an unserious weapon against climate change. Why is that? We’re going to see in this post. What is net zero? Simply, it is a building or property that produces as much renewable energy on-site as it consumes, typically over a year. Some utilities claim their net zero trophies for producing as much renewable energy as their customers buy. Why is Net Zero a Con? To answer this question in one word; exports. When a property or utility generates more electricity than it consumes, it must be exported to someone else.…

COP27, Elites, and Engineers

By Energy Rant No Comments
I have run enough marathons to have lost count, most of them in the last ten years, with the total approaching 20. Why would you do that, Jeff? I like the grind, double, especially when I can run negative splits and pass people the entire race rather than being passed the whole race. I’ve done both about equally. I guessed that winning marathon times had not changed much in forty years. Wikipedia confirms this with finishing times at the NYC marathon. Americans Bill Rogers and Alberto Salazar finished with the same times back in the 1970s and early 1980s as…

Renewable Interconnection Chaos

By Energy Rant No Comments
A couple of weeks ago, I drove across Southern Minnesota, starting in the SW where wind alley is, and therefore, hundreds, or maybe thousands of wind turbines. The following was my observation while cruising I-90. Since the turbines were not spinning, I can only assume that excessive wind forced the Midcontinent Independent System Operator to curtail several hundred megawatts of wind generation. This, for one reason, is why net zero is as worthless as a three-dollar bill, but also, utilities have power purchase agreements with these non-spinning resources, right? Who pays? The MISO hub prices were as follows that day.…

Design an Attractive, Cozy Home

By Energy Rant No Comments
Minnesota’s Clean Energy Resource Teams recently published an online article, Things I learned about heat pumps: a homeowner's perspective. I shared this with some folks, and in response, I was asked for general advice on new home construction. I am not a residential efficiency expert, but I performance-specified a new home built for my wife and me back in 2000, and in recent years I side-graded to a smaller home built in 1934. I learned a lot from both experiences. I won’t advise, but I will say what I would do if I were to provide a conceptual design with…

Developing Nations are Going Nuclear – Will the West Follow or Fall Futher Behind?

By Energy Rant No Comments
Last week I provided an extensive analysis of how Chernobyl’s RBMK reactor design and the chain of reckless events led to its 1986 disaster. The study sets the stage to explain why that won’t happen with power plants in the United States. Let’s take a minute to examine why nuclear power is a good fit for our needs. Nuclear Power’s Plug into Our Grid Commercial nuclear power plants operate continuously at full power for 90-95% of the year. They require an average of three to four weeks a year for maintenance and refueling. One charge of nuclear fuel, about 3%…

Safe Nuclear Power v Chernobyl

By Energy Rant No Comments
Green and climate change warriors – see how important nuclear power is to CO2 emissions in one chart, courtesy of the New York Independent System Operator (NYISO). The closure of two nuclear plants wiped out more than twice the carbon-free electricity generated by all renewables in the state. Why is nuclear power overlooked or not an option? I can think of three reasons: 1) it’s scary, and people don’t understand it; 2) it’s too expensive; 3) radioactive waste. Accidents and Disasters Reason #1, it’s scary, is due to prejudice and ignorance. There has only been one nuclear power plant disaster…

Phony Avoided Cost Models in a Free-Agent Market

By Energy Rant No Comments
The last two posts, Nuclear Power over the White Rabbit and the Clean Power Plan Corpse, demonstrated the fruits of an undiversified baseload fleet of power generation. Electricity prices, which were so low during most of my career that few cared about them, are soaring as natural gas - the basket in which all eggs lie - has become a global fuel. I predicted this as recently as 2017; Reverse Diversification Coming to a Utility Near You. Solar, wind, and storage will never compete with thermal baseload power generation in our lifetimes. I’m covering three things in this post due…
