August 6. 2023, I noticed a big error of mine in the energy conversions. Most of the article deals with energy flows in "Quads" or Quadrillion of BTUs because that's the unit used in the first graphic. Later in the article, when I was trying to quantify costs to electrify transportion, I said, "We need to add 19 Quads or 635 Megawatts of power generating capacity." I think that number is 635 Million Megawatts. Big difference.

It would affect the cost of additional fossil fuel plants--possibly much higher. I'll have a look and revisit calculations. I'm not sure that they are correct. They SEEMED correct, but now I'm not sure. I'll revise this post at some point if necessary.
