Four Steps to Energy Code Flatline

By Energy Rant No Comments
Energy efficiency program administrators can be quite conservative regarding change and innovation. I love hearing, “Bring us new ideas that have been successful in three or four other programs.” There you are! The pinch is on. Energy efficiency codes and standards have raised the bar consistently such that incremental savings from one code change to the next are exceedingly scarce. The gravy-train days of incremental widget-efficiency improvements, including lighting efficacy and heating and cooling equipment efficiencies, are quickly closing. Vehicles A nice parallel to diminishing returns on efficiency is vehicle mileage. The following chart shows fuel energy consumed per thousand…

Modern Electric Rates from the Slide Rule Era

By Energy Rant No Comments
Last week, we looked at Total Resource Cost (TRC) tests that were developed decades ago to put a high value on avoided source energy costs. That was right for the time, but not today. I demonstrated that energy costs, mostly dominated by natural gas, are near historic lows, while zero-energy-cost renewables supply more electricity than coal-fired generation. Of course, renewable sources have zero source-energy consumption. Yet, utility commissioners are laser-focused on keeping electricity prices in check and maintaining the reliability of the electric grid. Electric Rate Basics Like the TRC, most utility rates (tariffs) are stuck in the 1970s. I…

Eyes Open for Food and Energy Waste

By Energy Rant No Comments
General Russel Honoré delivered the closing plenary from last week’s AESP Annual Conference. He humorously but effectively preached to the choir about climate change mitigation. I will take one sub-topic he mentioned, food waste, and run with that this week. I may even expand it to the grocery store. General Honoré was the Commander of Joint Task Force Katrina, the hurricane. This is an excellent opportunity to pull out an article I read a few weeks ago, Dear Consumers, Please Consume Less, posted on Energy Central. Americans consume an average of 3,600 calories daily, while the recommended ration is 2,000…

Maximize Grid Battery Value with Smart Deployment

By Energy Rant No Comments
Time flies even during pandemics. Two years ago, I found the quote, “Casual observers are often wrong” by Charles Bayless with Public Utilities Fortnightly. Back then, the Rant topic was that battery storage increases carbon emissions – because “Batteries, or any storage, only swap dispatchable, conventional resources; never renewable resources. Result: increased emissions.” Whenever energy is converted from electricity to battery and back to electricity, the nasty second law of thermodynamics intervenes to steal some energy. The result is more source energy consumption and more GHG emissions. That introduction leads to today’s edition of “casual observers are often wrong.” This…

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…

The Sport of Energy Management

By Energy Rant No Comments
Last week I proved that energy management is too much work and hassle for the average schmo, unless… That is the subject of this week’s post. I am the youngest of four kids who lived on a farm, so walking or even riding a bike to Jimmy’s or John’s house was not a viable option. Play with the siblings? Pffft. We competed in everything from board and ancient-video games to table tennis. I was damn good at that, by the way. We Want to Destroy You We didn’t have soccer at all, but thankfully, one parent/organizer in a nearby town…

Prestige, Not Pain – Efficiency at Home

By Energy Rant 2 Comments
I call your attention to the brilliant marvel of engineering shown in the image below. This model was developed before most of you were born. It is the little diesel engine that could – get 60 mpg, in my second car – a 1984 Ford Escort Diesel. Most people didn’t even know they existed, but as a college sophomore, when I got tired of my crappy, rattling, vibrating, chintzy Mustang, I snapped up this baby for a deep discount from the Billion auto empire in Sioux Falls, SD.There was no air conditioning or power anything, including no power steering. It…

NMEC and Routine Monkey Wrenches

By Energy Rant 2 Comments
Normalized metered energy consumption, or NMEC, is another name for the nerdy term, EM&V 2.0. Why the switch? Maybe en-meck spills out of the mouth a little easier. Maybe EM&V 2.0 got the bad rap it deserved as I explained a couple years ago in Whale Bus or Airbus and Automated M&V in Your Dreams. We need not only the user's manuals for how to deploy NMEC; we need protocols for how to apply NMEC, where it works well, and where it doesn’t. NMEC Explained The following would never happen, but I need a way to explain how NMEC works…
