I'm starting to wonder whether the conventional wisdom of reducing carbon emissions in favour of more electricalisation is really solving the actual problem. As is often pointed out on HN, electrical cars are substantially heavier than their fossil fueled alternatives, and generate other pollution along the way. Furthermore, we're digging our lithium brines from the environment, without really understanding what all this lithium will do once it's leached out into the environment or what impact the mines themselves will have.

With the recent advances of turning CO2 into other substances, such as propane, should we be focusing more on closing the carbon cycle and simply be producing fossil fuels from the waste products of yesteryear?

Naively, it feels like we understand C, O and H, better than we understand some of the rare metals we're now introducing in the name of climate change.

Well the real answer is to reduce consumption. It can and should be done without sacrificing comfort. This is a very uphill battle against systems that are interested in distracting you by turning your attention towards fads (recycling, electrification, carbon capture) when in reality we need degrowth and permaculture. (Please read this thread a bit more, including my replies, before you tell me what I think degrowth means. I'm only using it to mean "less [economic] growth")

In a bit more detail:

How about less cars? More effective public transit is good for people and the climate.

Let's do away with golf lawns and pools for every house... Perhaps architecture can be adapted to suit the specific location instead of stamping the same stock photo "American house with garage that can fit 4 cars." Look at passive cooling and stuff. [Again, I'm talking about redefining comfort. Is a personal pool and large car and trimmed lawn really, honestly, what makes you comfortable? Or is it more a product of culture and advertising? You're absolutely free to believe either way, and I don't want anyone to force you to do anything.]

And honestly, we need to consoom less. Devices should not have a lifecycle of one year. You and I don't really need all these gadgets and trinkets, either. Let's stop buying random things

If you think this is a distraction or that it won't work because we can't get everyone to agree: Degrowth and permaculture requires honestly no critical mass. You can choose to buy things that last longer, and use them a bit more. Learn to fix things, etc. These are all nothing but straight benefits to you (more money in your pocket, skills that can make you more valuable in the current system, more time available now that you aren't swiping short form videos all day).

You went straight from "we don't have to lose anything" to "except of course for cars, lawns, pools and technology in general" apparently without noticing the contradiction. This is a good example of why degrowth advocates have no credibility and always come across as anti-civilization Amish wannabees.

There is no such thing as degrowth outside of recessions and wars. If you want to reduce your own consumption, do so! The rest of us who believe in material progress will increase ours to make up for it.

I think the connection between technology/consumption with comfort is constructed by our system to manipulate you. The concepts are not synonyms. I honestly don't think having a lawn or a big car or pools or the newest devices bring me significant comfort.

In fact, I feel like if we did things less capitalist, we'd be more comfortable. How about devices that last longer and don't force fashion on you? (I'm looking at apple removing headphone jack, changing the notch, glued batteries, etc)

Further, how about shared pools that can be more comfortable and without requiring maintenance from you? (Or do you hire someone to take care of it for you?) Same with lawns and cars. Why not parks and transit systems?

Where we live the parks are always safe and almost always clean. The same for the transit network.

There are plenty of apparently weathy places where that appears not to be the case.

Good for you, then don't bother with them. But you're in a tiny minority. The rest of us do in fact very much enjoy chilling out in a nice private pool surrounded by a big lawn on a warm sunny day, relaxing on an inflatable whilst listening to awesome music streamed to our AirPods whilst we drink chilled beer and wait for friends/family to drive over and join us for an epic grilling session.

Normal people don't like these things because we've been "manipulated" by "our system", get a grip. We like these things because they're extremely enjoyable perks of living in the modern world.

Comfort != "stuff". Yes in some cases stuff brings additional comfort, and what stuff does that varies by person but there isn't anything inherently contradictory in what they said imo.

I moved from an area where I needed a car to an area where I don't and doing so increased my comfort. If areas like this were more accessible I think a lot of people would willingly degrowth and become more comfortable at the same time. Of course people shouldn't be forced to lose their car or move to a denser area if they don't want. And I like my gadgets but it is pretty ridiculous that their lifespans are artificially shortened to prop up profits. I have a computer from 1984 that still works, I would bet a huge amount of money none of the devices I buy today will work in 2062.

You say of course, but that's exactly what eco-warriors want. Notice how "picture" doesn't think of his fellow humans as fully real, thinking people with their own fully developed opinions. He thinks we're all manipulated into wanting things, and that only if "the system" wasn't "distracting" and "manipulating" us with gadgets and private pools we'd all realize the superiority of collective ownership.

This is a very dangerous attitude. If you don't respect other people's views, and if you think they're all a product of manipulation you definitely don't, then you won't have any compunction in overriding them by force. That's why the degrowth agenda is strongly associated with the road and runway glueing brigade: they don't care if an ambulance can't get past them and someone dies as a result, or if you can't get to work and lose your job. Your preference for petrol powered transport is merely a manipulation by the system and thus has no validity.

In practice, comfort is mostly a function of stuff. Yes there are aspects that aren't to do with stuff but they're things that are really hard to move the needle on: loving families, low corruption, stable government and so on. Once you've got those things it's much easier to raise standards of living with incrementally better stuff than incremental improvements in quality of government, for example.

I can't say I agree, this feels like a very uncharitable reading of his/her posts. Unless it was edited in after the fact they even said "You're absolutely free to believe either way, and I don't want anyone to force you to do anything."

While it would be insulting to call any individual person's preferences a result of brainwashing, I don't think it is a stretch to say that at a societal level preferences are shaped by mass-media and advertising. Improving access to and making people aware of less resource-intensive forms of comfort doesn't have to come from an authoritarian place. One of my major motivations for seeking out a more walkable area was urbanist YouTubers extolling the benefits. I suppose one could argue that things like bike lanes are hurting drivers but if a city's transit priorities stem from local politics and preferences I don't think it can be reasonably argued that making any particular transit method a priority is more authoritarian than another.

> In practice, comfort is mostly a function of stuff.

No question that it is a variable for most people but I'm not sure I buy that it is the most dominant one. All other variables being excluded, time to do what I want is at least as important for me as stuff (luckily I like my job so time/money aren't usually in conflict). And I think for many people "stuff" like cars and nice lawns aren't inherently drivers of comfort, but rather just possible reifications of goals like "pretty yard" or "fast/easy transit," both of which can be realized in less resource intensive ways. For the yard example, that might be a native garden or xeriscape (in some cases there are rules against these, which actually goes against freedom imo).

Yes, picture edited that into their post after I replied to it.

I don't personally believe people when they say that anyway, so I'd have taken the same stance even if the post had said that originally. Collectivists like that are never happy if people can make their own personal choices. That's why we now have government mandated phase-outs of liquid fuel vehicles on the horizon whether individuals like it or not. They campaign and bully until they get what they want, which as picture states very clearly is bans on anything convenient in favor of non-private property (n.b. they're fine with swimming pools as long as they're shared pools, and already admitted their actual motivation is dislike of capitalism not a belief that restricting golf will actually achieve anything).

If we don't degrow now, we are heading towards recessions and wars anyway. And not small ones: count billions of climate refugees... that's probably the end of democracy everywhere.

The big problem with degrowth advocates don't say what the new world looks like in detail. They say we should go rid of problems, and we should, but those are the low-hanging fruit. They will help but won't be enough.

How do you propose to use much less energy without starving everyone? Where does the energy come from if not fossil fuels without conscripting people to be peasants? Does it matter if mass death is caused famine or "degrowth"?

> How do you propose to use much less energy without starving everyone?

That's the whole point: degrowth is about re-organizing society such that we don't starve. There are big efforts of planning for that in many places. Look at the "shift project" in France. It seems to me that the US are very, very, very far behind on that matter. The US seems to still be stuck on the Silicon Valley mindset ("they will save us with new technology"). But that's not representative of the rest of the world.

> Where does the energy come from if not fossil fuels without conscripting people to be peasants? Does it matter if mass death is caused famine or "degrowth"?

The idea of degrowth is that in order to avoid famines, we have to drastically reduce other stuff and reorganize society. Planes are not even a question there: planes will go away, because everyone agrees that we'd rather eat that fly. There are many decisions that are harder to make, though.

Those who don't believe in degrowth and instead think that "there will be a miracle technology that will save us" are just naive. Degrowth advocates are the ones who are actually trying to play with the cards they were dealt.

The first problem is no details like how much needs to be cut. You suggested it is impossible to build enough solar. Do we have to shrink to 10% (renewable electricity) or 20% (plus nuclear)?

A good example or problem with degrowth is proclamation that things like planes won’t be possible. Aviation is 2% of emissions. There are lots of little things that they add up. Like concrete being 3%, but nobody says that have to give up concrete. The big ones are things like heating and cooling and transportation that are hard to give up.

The other problem is that we mostly know how to solve aviation. Hydrogen or liquid fuels should work, both produced from green energy. New technology but no miracles. We know how to do green electricity.

I agree with you that we need to change the world a lot. But it won’t work if impose suffering on people. Or do things that don’t work or don’t help.

Aviation came with oil, it will disappear with oil. It's not a problem of emissions per se, it's a problem of energy. Fossil fuels are not unlimited and we don't know how to completely replace them.

> The big ones are things like heating and cooling

We need to work hard on building isolation, obviously. And people need to live in smaller habitations.

> and transportation

We need more trains

> Hydrogen or liquid fuels should work, both produced from green energy.

Same thing: if you look at the numbers, we won't have enough green energy to produce enough hydrogen for aviation, even if technically we can make planes fly with hydrogen. We will have to choose where we use our hydrogen: for planes, or for steel and agriculture?

> But it won’t work if impose suffering on people.

Yep, we need to teach people and hope they accept to do what's needed to survive.

> Or do things that don’t work or don’t help.

Totally agreed here. Hoping for anything short of degrowth doesn't help. We need everything PLUS degrowth. And still, it will be hard because climate is already pretty messed up (with inertia) and biodiversity is looking bad.

And thinking that we will have inexhaustible amounts of green energy is not hyper-optimistic and hyper-arrogant?

We don't currently have inexhaustible amounts of green energy, and we don't have any viable solution right now. If you think that because we can make 1 solar panel, we will be able to replace fossil fuels, then you have obviously never done any kind of engineering in your life. Problems come with scale. It's not being hyper-pessimistic to know that.

It's immediately obvious from basic physics that the world is bathed in green energy. It's availability is thousands of times greater than fossil fuel energy: https://www.freeingenergy.com/the-earth-gets-more-solar-ener...

The problem with doomers and degrowthers is that they are pretty ignorant people. They just assume that there's no solution or that green energy is just too weak to solve problems. This is why they are arrogant and not just pessimistic. They believe they already know the answer despite never looking for possible answers in the first place.

And that's perfectly fine. I'm not forcing anybody to do anything. I just provide my opinion on what I believe is good info.

So it's a personal dig about how I'm communist? I'm not, I don't think either state organization or anarchy will fulfill the promise of socialism to achieve an egalitarian society. But I do recognize the benefit of "public goods" that the "socialists" bring to the table, like roads and hospitals. Communism has failed many times throughout history, but I certainly don't think laissez-faire capitalism is any good either.

If you are a die hard believer that capitalism will lead to the best outcome for people, then ignore anything I say. If you perhaps don't realize how strongly identifying with the name of an idea alone lead you to a narrow perspective of the world, I urge you to take some time to reflect on your own opinions.

Last I checked, solar power is very cheap. Your problem is the same as with many degrowthers, you are basically stuck in the past and refuse to change your mind despite new information. It is the arrogance of "knowing everything" while not having any desire to learn.

You completely miss my point. You are the arrogant want saying "don't worry, we can solve it, we know". I am the one with humility saying "guys, I have seen how engineering works, it's always harder than we think". Tell me: how do you make plastic with solar energy? Because last time I checked, plastic was made of oil. There are tons of engineering problems (from the fact that nobody has ever produced that much solar energy to the fact that you can't control solar energy - what do you do when there is no sun? Happens at least every night...).

Plus, if your only reference is the price of solar power today, then you are highly uninformed on the subject at hand. Of course solar power is cheap: in many places it is subsidized, and it is built with cheap, abundant fossil fuels. But make no mistake: solar today is absolutely marginal. So you are extrapolating from the current marginal energy production of solar to 100% of the world, with the only argument that "last you checked, solar today is very cheap" and "those who believe they know slightly more than me are arrogant, I won't listen to them".

> while not having any desire to learn.

Let me take you on that. I will share with you my favorite introduction book on the subject (it is cheap, from a really respected french engineer, and it took me 5h to read). If you do have any desire to learn, read it seriously. Now in all fairness, if you share with me the title of a serious book that explains why degrowth is "arrogant and stupid", I commit to reading it.

Do we have a deal?

My choice is "World without end" (in French: "Le monde sans fin"):

If you can make hydrogen and capture carbon, you have the ingredients for making plastics. It will likely be more expensive than today’s plastics, at least initially, but for critical needs like medical devices, this is totally acceptable.

You can build solar and wind power without fossil fuels, or at least not much. We are able to power large vehicles and industry with renewable energy now. Most notably, with the advent of green steel, infrastructure projects in general no longer require significant use of fossil fuels. Now to be fair, this was not known to the greenies, who thought that solar panels on the roof and an EV in the garage will magically solve everything. But this is known to those who actually study this problem. This problem is rapidly resolving itself in reality.

I cannot read a book in a short amount of time. But from the sample it is just repeating fairly simplistic arguments against green energy. It is mostly a repeat of what was being said on theoildrum.com from a while back. Even then, they were mostly wrong. These days, the few areas where they were right are also being proven wrong. It is akin to the “god of the gaps” argument, where the gaps where we didn’t know how to eliminate fossil fuel usage are constantly shrinking.
