Dive Into Cement Manufacturing Emissions

By Energy Rant No Comments
Over the years, I’ve seen numerous mentions of decarbonizing concrete or cement. Random articles describing the need and means to decarbonize cement include this McKinsey article, this DOE post, and this Canary Media article. Those don’t cut it for me. I set out to explore cement making and why it is so carbon-intensive. But first, some terminology review is advised to differentiate cement from concrete. Growing up, in college, and even post-college, we used the term cement synonymously with concrete. E.g., “cement hands” to describe a guy who couldn’t catch a basketball or football or “cement head” to tell civil engineers. Each of…

Ambient CO2 Scrubbing Grifters

By Energy Rant No Comments
The origin of this post is a spicy Zerohedge article, The Phony Climate Change Catastrophe, specifically, carbon capture from ambient air. That reminded me of an April article in The Wall Street Journal that referenced the same redonkulous effort by Occidental Petroleum to self-absolve its CO2 emission contributions by vacuuming CO2 from ambient air. If this sounds absurd, you have my company. Incidentally, chief investors in this technology include Warren Buffet (Berkshire Hathaway), the largest shareholder of Occidental stock, and Bill Gates. These grifters are always first in line with their golden tin cups when there is tax money available…

North Carolina’s Carbon Plan Criticized for Lack of Specifics, Energy Reliability and Possible Higher Bills

By Carbon Reduction No Comments
Original Source: North Carolina’s Carbon Plan criticized for lack of specifics, energy reliability and possible higher bills (wral.com) A plan to significantly reduce carbon emissions in North Carolina is receiving widespread criticism. Environmental groups believe the state’s first Carbon Plan lacks specifics while other critics are concerned that too much reliance on renewable energy will be costly to the state. Some customers believe increasing renewables will mean a less reliable grid. The passing of House Bill 951 requires Duke Energy and other electric utility providers to reduce carbon emissions by 70% from 2005 levels by 2030 and reach net-zero emissions…

Climate Resilience – Flood, Fire, Ice

By Energy Rant No Comments
A reader last week asked, “What kind of home can withstand fire, hurricanes, floods, heat domes, and polar vortex?” This is a great question. I love the challenge, so here we go. Flooding and Landslides Think ahead and ask yourself, “what if” before or even after buying a property. For example, my first home was built to suit my engineering brain. It is wonderful for heating with a wood stove and is very practical; it is not huge and can be expanded with nice amenities for a family. It is built on the side of a bluff in the great…

Civics Lesson in Federal Carbon Policymaking

By Energy Rant No Comments
As the weeks, webinars, conferences, and workshops click by, I contemplate the barriers to decarbonization policy. Next week in our decarbonization course through AESP (register while there is still time) we will discuss policy on the state and regional levels. This post describes federal policy. This next chapter of the discussion comes via the EE Global Forum, an online conference presented by the Alliance to Save Energy last week. That provided more fertile soil to consider issues and barriers with decarbonization policy. The Alliance is rooted in the Washington area and is committed to efficiency at the national level. The…

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.…

Zero Net Cost for Zero Net Energy – Melt the Calf

By Energy Rant No Comments
Have you ever thrown a cat into the deep end of a swimming pool? Neither have I, but I bet they wouldn’t like it. Likewise, status-quo program evaluators will not like what’s coming down the pike for several reasons, starting with one in this post for residential and commercial new construction programs. A few weeks ago, I read a post from fellow small-time blogger (speak for yourself, Jeff) Joel Gilbert. His topic was low carbon foods. He wrote, “But, I offer this observation :  I have never seen such a groundswell of enthusiasm around these ideas.  Perhaps it is being…
