You're pretty much in the ballpark there. ... I believe the problems we have are not really technical, but cultural.
Okay, then. I think that you are putting the cart before the horse.
I respectfully submit that you are hanging your hopes for a better society on a technical catastrophe. There are several problems with this approach.
First, as we have been pointing out, peak oil is not the end of civilization. It does not even mean the imminent end of oil, or the end of energy, just an economically-forced transition to different energy systems.
Second, if you want people to live differently, you need to entice them. In a greener world, people will still have their usual pursuits, but will do them in a more-efficient and less-destructive way. Helping people with this transition, showing that new means are practical without compromising they ends they genuinely care about, is a better way to encourage positive cultural change than trying to restrict behavior with scary warnings that lack a factual basis.
Third, some people
already live well but differently, burning smaller amounts of fossil fuel than people in the U.S. Even JMG points this out about Europe in the video you cited. Some of these are painless cultural choices that don't require catastrophe to enforce. For example, I intentionally sought out and chose to buy a house in a city where I can take the bus to work, my partner can cycle to work, and the city center is within a ten-minute walk. Look for these kinds of choices -- and others -- becoming more popular, in addition to the non-fossil technical improvements we've already outlined.
Finally, whatever your cultural preferences are, there is no guarantee that they would be realized during or after a serious civilizational crisis. If anything, things would get uglier both morally and aesthetically. This is not something to hope for.
The Grand Archdruid puts it best in this video...
He's more hopeful than I expected.
He even says that the narrative of "complete overnight collapse" is a myth, in the sense of "myth" as a defining cultural narrative. We in this thread have been pointing out that it is also a myth in the sense of an untrue just-so story. Watch the video again from 4:45 to 5:11, and ask yourself if JMG is describing your opinion about peak oil.
At the same time, I don't think that the solutions to our energy problems are "silver bullets" that "they'll come up with". Most of the solutions -- technical and logistical and cultural -- already exist.
I already mentioned some of my lifestyle choices, but it will take time for more people to do this. People make changes as opportunities arise. Few can or will drop everything for a massive overhaul of their lives. Also, it takes time to expand the reach of new infrastructure. As oil prices rise before all of these improvements are 100% ready, a lot of people will find out the true meaning of the "mean time". But it won't be the end of the world.
Finally, I disagree with Greer somewhat regarding the myth of progress. Sure it's a narrative, but I don't think everyone in our society (especially skeptics) swallow it. For example, I temper optimism by looking at the past's outright mistakes and the times we have fallen backward, both socially and intellectually. I'm fully aware that there are no guarantees of continued learning or continued material improvement, so the Archdruid has no revelation for me.
But the physical facts of the world remain regardless of the stories people lay on top of them. Objective reality is immune to the charge of "myth" as false fable, even when people spin stories about what to do with its boon and within its limits.
In other words, put your horse before your cart.
A sinking system generally grows more conservative....
Do you mean instead that a society in crisis is more likely to hold tightly to established ways of life and less likely to try new, possibly more-adaptive, ways?
If yes, are you referring to the way of life that requires fossil-fuel consumption?
If yes to that as well, I must say that I think only a very small number of Western, Northern people think that burning coal and oil, as activities in themselves, are central to their way of life. The rest of us are happy to continue the more meaningful ends (such as transport, communication, construction, and entertainment) using different means (such as electric power). The Promethean fetishists are and will continue to be an eccentric micro-cult. (I'm not even sure they exist.)
Or did you mean something else?
I wouldn't say "cultural change" is my priority, I just find it inevitable.
It is indeed inevitable. But I think we can and should make it
viridian and electric, not a new dark age.
By the way, I encourage you to read this last link. It has had a good influence on my choices over the last ten years. And you might like it (or at least some of it), too.
