Hmm... and combine with EVs coming of age, a Moore's Law type growth curve for solar (and solar EROEI), etc., and perhaps the high energy costs of the recent past are gone for a while.

I have to admit I'm surprised. I totally bought the idea that oil would never be this cheap again for fundamental physical reasons. But perhaps that made it a bubble. A true bubble must have a "story" about how it's "different this time" that manages to convince huge numbers of people.
