Plus, the 10 most-read articles on my Substack and an updated chart on global energy use.

It may be odd to start a year-end retrospective with a prediction, but here it is: Historians will mark 2025 as a hinge year for climate and energy issues. The reasons for my prediction are obvious.

As 2025 comes to a close, I put together this list of the year’s most consequential energy stories. I also dug through the 80 pieces I posted on Substack and compiled the 10 most-read articles.
Let’s take a look.
