This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
Is there any evidence the EROEI is negative? I've looked at a few sources and the numbers vary wildly, but they've all been positive for nuclear.
https://www.scientificamerican.com/article/how-to-measure-true-cost-fossil-fuels/ - this one has Nuclear as one of the lowest.
https://festkoerper-kernphysik.de/Weissbach_EROI_preprint.pdf - this study shows the opposite with Nuclear as one of the highest.
Regardless, both have a positive number for nuclear.
In general, my surface-level research has shown wildly varying levels of claims.
Wikipedia claims there was a 2019 study by the economic thinktank DIW Berlin showing no nuclear plants were profitable, but the source is some guy's blog, and his blog doesn't have a source to the article he claimed he saw it in. There then is a source to a counterclaim study that goes nowhere...
This source here says only 1/3 of US power plants are unprofitable
But on the other hand, there is this report from 2021 and 2022 indicating that at least in the northeastern part of the united states Nuclear energy was making profit in recent years.
I've even seen articles claiming renewable energy like solar and wind is cheaper and more profitable than nuclear energy, but I don't know if the profit/cost values used in the comparisons were calculated using the same methodology. Like if they're factoring in subsidies for nuclear but not for solar for example.
It's pretty clear each source is calculating costs and profits differently. All I've been able to gather from my short research is that like most hot topics, there are different groups with different biases in calculating and claiming things to support their agenda, and that it is extremely difficult for a person to be able to discern the truth without investing a lot of effort into looking into the actual methodologies and processes behind the calculation and sources of data. Perhaps I'll take a deeper look at another time.
On a somewhat related note, one thing to keep in mind about nuclear energy is that it is incredibly space efficient compared to other renewable energy sources such as wind/solar/hydro energy. There is only so much land use we can dedicate to wind/solar so as long humans continue to demand energy usage I think there is no choice but to eventually go to more nuclear energy, unless new more efficient forms of energy generation are discovered.
