| It's worth thinking about past unprecedented humanity-wide energy transitions to get a taste of what might be in store. Stross mentions the combustion engine revolution, which brought us urbanization, made democracy widespread (virtually eliminating monarchy), created the urban proletariat, ended slavery, made humans literally fly, lit the cities at night, obliterated most of the world's cultures through colonialism, created company towns where you got deeper in debt the longer you worked, etc. The previous similar event was the Neolithic Revolution in which settled agriculture began, which probably brought us monarchy, cities, literacy, metallurgy, slavery, malnutrition on a scale previously unimaginable, and virtually everything we think of as traditional. (But not pottery. Pottery is much older; it just hadn't yet spread to where people were inventing agriculture.) This time will be a bigger change, I think. The amount of energy available from the sun is much larger than what people use today, perhaps 7000× even at Earth's surface. This is now cheap to use. Many things that have always been inconceivable are now feasible. Someone is going to fease a lot of them now even if I wish they wouldn't. Quibble: China's solar panels are not thin-film. |

| The way you describe the transition events elides the incredible instability that people living through them experienced (wars, revolutions, famines, etc.), which I think is what Stross is getting at here, and ultimately is probably right about. Will things end up better? Maybe, and based on history you could even make a case for "probably", but will it be better for _us_, the ones alive _right now_? Again, based on history, almost certainly not. |

Maybe, and based on history you could even make a case for "probably", but will it be better for _us_, the ones alive _right now_? Again, based on history, almost certainly not. I find myself in this odd internal conflict. I genuinely care about the planet, but I'm approaching 60 and childfree, and have definite misanthropic tendencies. While there's big part of me that's a tree-hugging greenie and who wants to attend every protest about human rights abuses and war, here's always a loud voice in my head telling me "it only all needs to last another couple of decade without completely collapsing". | | |

| ▲ | bobthepanda 11 hours ago | parent | prev | next [-] | | all of those things were also very common outside of energy transitions until about the last century. for all of its faults, one thing the globalized system has allowed is that it makes relieving famine possible by shipping food from other parts of the globe. | | |
| ▲ | kragen 11 hours ago | parent [-] | | Yes, famines were unavoidable before the steam-engine; since then they have become purely politically produced. |

| Strictly speaking there's never been an energy transition in the sense of replacing one source of energy with another. Instead, the different sources of energy have been piling on top of each other. [1] So while PV is growing at an unprecedented pace, it still represents only 2-3% of total energy production. About 75% still comes from fossil fuel. Today we burn more fossil fuels (and incidentally more wood) than ever before in human history. So the term "energy transition" is inaccurate at best.

| ▲ | kibwen 13 hours ago | parent [-] | | > there's never been an energy transition in the sense of replacing one source of energy with another We have. This is thinking too narrowly about energy as "driving a turbine" rather than doing work in general. Horses, oxen, and other beasts of burden have been almost completely marginalized in our modern economy. The same could certainly happen to steam-powered turbines (coal, gas, nuclear, etc) if the economics end up working out that way. | | |
| ▲ | m4rtink 11 hours ago | parent | next [-] | | Yeah, even old water mills - while the weirs and water supply channels might still stand, the water wheels are long gone, with a few exception not worth replacing by a modern small water turbine generating electricity. It is simply not economical to exploit this (originally critical) source of power as its is so small in absolute numbers compared to all the necessary maintenance. | | |
| ▲ | kragen 11 hours ago | parent [-] | | A few years back I visited an old water mill called Itaipú. It has forty water wheels still in operation, providing a total of 14 gigawatts peak. At the time I visited, one of the water wheels was providing 95% of Paraguay's electricity, and the other 39 were providing 25% of Brazil's electricity. It turns 50 years old next year. In 02020 its average production was 8.7 gigawatts. They did have to replace one of the water wheels a few years after I visited: https://www.youtube.com/watch?v=thcIrM31tZ4 Brazil uses more electricity now, some 80 gigawatts, so this one water mill only produces about 10% of it now. It is true that many older water mills are no longer in use, though. Maybe 50 years to you is not old! | | |
| ▲ | Tossrock 7 hours ago | parent [-] | | That's a hydroelectric dam, not a water wheel. A water wheel captures mechanical energy directly for eg grain milling, not conversion to electricity via turbine. |

ICE => democracy? I don't see the link. Most of the things you speak of came with the industrial revolution, not with oil. |
| |
| ▲ | kragen 13 hours ago | parent [-] | | You seem to have misinterpreted what I was saying, possibly due to being unfamiliar with the terminology. It was Watt's external combustion engine that brought the industrial revolution and made democracy widespread, not the internal combustion engine. | | |

| > ended slavery We (mostly) ended human slavery, but I don't think its accurate to say we ended slavery in general. Oil gave us a reason to stop enslaving humans for labor - a single barrel of oil equates to the amount of work a human can do working 8 hours a day for roughly a decade. We didn't stop slavery all together, we found a more efficient target of our enslavement. We'll do the same with AI (or at least we'll try), should actual artificial intelligence exist. |
| |
| ▲ | kragen 13 hours ago | parent | next [-] | | I'd never done that calculation, but that's about right; https://en.wikipedia.org/wiki/Barrel_of_oil_equivalent is 6 gigajoules: You have: 6 gigajoules / 10 years (8 hours/day)
You want: W
* 57.039776
/ 0.017531626
That's at least in the ballpark.I think that from a moral point of view it's accurate to say that we ended slavery in general, or at least mostly ended it. Energy slaves made of barrels of oil or solar panels don't involve the same suffering and cruelty that human slavery does. | | |
| ▲ | _heimdall 5 hours ago | parent [-] | | Energy slaves made of barrels of oil come with a lot of external costs that do impact living things though. I lived on the gulf coast when during and after the BP oil spill, countless animals suffered due to that oil spill. | | |

| ▲ | perihelions 21 hours ago | parent | next [-] | | Ironically for the parent's thesis (cheap energy replacing human slave labor), one of the major objects of modern slavery is... the manufacturing of solar panels, https://www.nytimes.com/2023/08/01/business/economy/solar-xi... ("Solar Supply Chain Grows More Opaque Amid Human Rights Concerns / The global industry is cutting some ties to China, but its exposure to forced labor remains high and companies are less transparent, a new report found") https://www.csis.org/analysis/dark-spot-solar-energy-industr... ("A Dark Spot for the Solar Energy Industry: Forced Labor in Xinjiang") (Maybe there's some kind of evil Jevons Paradox for slavery, where the automation of human labor counterintuitively increases total slavery; i.e. the technologically-augmented effectiveness of slave labor increases the value of slaves). | |
| ▲ | _heimdall 6 hours ago | parent | prev [-] | | The source of 27 million slaves today is outdated. More importantly, the source paper referenced by the BBC here doesn't show any source for such a number, the closest it comes is to reference two specific examples of slavery, Sudanese slaves captured by paramilitary or government forces and sex slaves in Mumbai. Both examples are listed with estimates topping 90,000 enslaved. In no way am I saying slavery is no longer a problem, one slave is too many. I chose not to go after the parent comment's claim that slavery has ended because that wasn't the important to the point I was raising. |

| ▲ | ctoth 14 hours ago | parent | prev [-] | | Wait, are you saying we ... enslaved oil?
Type Error!
I'm reading that wrong, right? | | |
| ▲ | _heimdall 5 hours ago | parent [-] | | Well that would depend heavily on how you define slavery. Most people probably consider slavery something that can only be imposed on another human. I'd be in the minority considering animals raised in industrial farms and meat operations to be enslaved. I'd be in an even smaller minority to consider that plants raised in commercial fields may be enslaved, there is at least the possibility that plants may experience the world around them and their existence in it more than we give them credit for. I don't know that I'd say we enslaved oil, I'd say we enslaved nature more broadly. |
