Bipartisanship: Clobbering Corporate Climate Initiatives

By Energy Rant No Comments
New York Attorney General Letitia James is suing JBS USA Foods, the country's largest beef producer, for misleading the public with its net-zero greenhouse gas emissions plan by 2040. Not to be left behind, Attorneys General from Iowa, Kansas, Nebraska, and Tennessee are firing warning shots across the bows of companies like Target, Tyson Foods, and grocery store parent company Ahold Delhaize. Headline: Democrats and Republicans align against corporate climate change plans, particularly net-zero targets. What? Why are those companies targeted while there are all kinds of Hail Mary moonshots fired by governments (local, state, and federal) and other corporations?…

Decarb Warriors

By Energy Rant No Comments
Last week I read a statement from a retail energy provider. It said, “100% green rates, always.” It doesn’t work that way. An aggregation of power sources, including renewable, nuclear, coal, and natural gas, are supplying the grid at any given time. The little electrons aren’t tagged by source and routed to any given customer(s). Second, even if that were impossible, er, I mean, possible, it’s shoving more hydrocarbon electricity onto someone else. In this way, it’s the same as the net zero con. Cheap but Unreliable Generating renewable power is easy and inexpensive, but as described in the net-zero…

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…

China Holds the Climate Cards

By Energy Rant No Comments
This week’s post is prompted by further research developing my decarbonization course scheduled for May 19, 2021, via AESP, and information provided by the American Energy Society. Would you believe the course is filling up? Just asking. I like and respect the American Energy Society for its no-spin reporting. Again, this week we are looking at carbon emissions. Last week I reported that the carbon intensity of US-generated electricity fell by 40% from 1.45 lb/kWh to 0.89 lb/kWh. This week, via Energy Society’s newsletter, Energy Matters, the Lawrence Berkeley Lab reported that carbon emissions are down 40% in absolute tonnage…

Answer: Avoided Cost – What’s the Question?

By Energy Rant No Comments
“Can I ask a question?” My response to that, in good company, is, “You just did. Would you like another chance?” Now that, my friends, is a paradox. As you ought to know, I’m preparing a mind-blowing three-hour course on decarbonization for AESP’s Spring Training. One conclusion: 100% decarb is going to take decades and it will be expensive and disruptive. A lot of progress has been made, but it has been easy for reasons I will explain next following this chart, which shows how decarb cost will soar as the percent reduction increases. Average CO2 emissions per kWh produced…

Combined Heat and Power – a Serious Decarb Weapon

By Energy Rant No Comments
A few weeks ago, we reviewed electricity storage technologies, barriers, and issues. One storage technology is the lowly lead-acid battery, which forms the backbone of uninterruptible power supplies for data centers. They are inexpensive with readily available materials, are 100% recyclable, and therefore, they get no attention. Why? Elon Musk, the ultimate hype provocateur. What happened to the PowerWall, by the way? Disruption of rational thought? A web search of “annual Powerwall sales” results in nothing but distantly tangential content. Similarly, the utility industry, our industry, other companies, and people chase the flashy objects (squirrel!) to obtain decarbonization targets. Flash…

Net Zero: An Unserious Weapon Against Decarbonization

By Energy Rant No Comments
You all know people who are always going to do something great but never make it happen. Consider the hapless New Year’s resolution for which someone plans to lose weight. They successfully diet between a cheeseburger and fries for lunch and a mound of pasta with rich sauce for dinner: the “diet” lasted a few hours and accomplished nothing. The empty New Year’s resolution de jure for decarbonization is net zero, where similarly, there is excess at times and shortages at other times. Whether it’s net-zero-energy building design or net-zero-carbon electricity production, the achievement is easy and similarly not helpful.…
