Energy abundance depends entirely on the RATE of energy flow

Posted on August 24, 2021 by

Preface. Below are excerpts from two articles on why the FLOW RATE of oil is what matters for our fossil-fueled civilization. It’s like how, when filling up a bathtub, you want to turn the faucet on as high as it … Continue reading →

Diesel is finite. Trucks are the bedrock of civilization. So where are the battery electric trucks?

Posted on August 17, 2021 by

Last updated: 2023-1-21 Preface. Heavy-duty diesel-engine trucks (agricultural, mining, logging, construction, garbage, cement, 18-wheelers, and more) are essential for doing the actual work of our fossil-fueled civilization. Without them, no goods would be delivered, no food grown, nothing manufactured, no … Continue reading →

Aging nuclear power plants should be shut down

Posted on August 3, 2021 by

Preface. Below are my notes from the Greenpeace 146-page “Lifetime extension of ageing nuclear power plants”.  Even if you don’t understand all the terms, read on anyhow, since it certainly conveys why nuclear plants grow more dangerous with age.  Imagine … Continue reading →

Trucks running on CNG or LNG

Posted on July 23, 2021 by

Preface. My books “When Trucks stop running” and “Life After Fossil Fuels” explain why trucks can’t run on electricity — batteries simply don’t scale up, they are too heavy leaving little if any room for cargo. A catenary system has … Continue reading →

Biogas from cow manure is not a solution for the energy crisis

Posted on July 17, 2021 by

Preface. Smil’s article about biogas sums up why it won’t contribute to energy shortages as fossils decline. Biogass doesn’t scale and is easy to muck up. Hayes (2015) also makes this case, pointing out that even if every ounce of … Continue reading →

Microchip fabrication plants need electricity 24 x 7 for four months

Posted on June 25, 2021 by

Preface. I explain in both of my books, When Trucks Stop Running and Life After Fossil Fuels, why heavy duty transportation and manufacturing can’t be electrified, as well as why the electric grid can’t stay up without natural gas to … Continue reading →

Negative energy return of solar PV in Northern Europe

Posted on June 16, 2021 by

Preface.  I once yanked this paper after huge blow back, almost as bad as nuclear proponents, but in the past few years, I have no reason to doubt Ferroni and Hopkirks methods, boundaries, or conclusions, so I’m putting this post … Continue reading →

Why we aren’t mining methane hydrates now — or perhaps ever

Posted on June 10, 2021 by

Preface. Methane hydrates are far from being commercial, and probably always will be. Scientists and companies have been trying to exploit them since the first energy crisis in 1973 to no avail. Nor are they likely to trigger a runaway … Continue reading →
