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 -
OK, I'll bite. I'm not anti-nuclear, but hardly pro either. 20 years ago I was enthusiastic, but overall now I think that nuclear has only a modest role to play.
Nuclear never has never been particularly economically attractive -- successful programs have needed to be subsidized by states for national security reasons. The predictable costs are huge and mostly occurred before the plants even come online. The unpredictable costs of accidents, attacks, and proliferation are really hard to value, and require large states or as yet imperfect international control systems. The technologies needed for nuclear to be perform at its best (small safe thorium reactors and the associated reprocessing networks) aren't yet developed. Overall nuclear wins only if you want a to build a power source 15 years from now, to deliver stably priced energy in a stable environment for the next 70 years.
But that's not what we want. We want power sources that can be built in 1 year, that and are priced for a lifetime of 20. We need technologies that can be deployed at a local scale and are immune to political disruption.
I'm sorry, but unicorns do not exist.
Many renewables, and some fossil fuels if you ignore fuel supply, satisfy those requirements. Pretty much everything meets them better than nuclear.
None of those are immune to political disruption, you can't ignore fuel supply, and very little grid scale anything can be built in 1 year.
Solar photovoltaic, for example, doesn't need international, state, or even regional stability to function, which nuclear does. Solar installations are trivial to build -- even the largest installation, Noor Abu Dhabi only took 23 months. Onshore wind is similar. Natural gas, AFAIK, has become very quick to construct, though the political coordination required extends across to the extraction area, as you say. The point isn't the precise details -- nothing's perfect -- but rather the huge difference in time and risk profiles with nuclear.
Solar PV also has that irritating issue of only working in the daytime; "working all the time" is one of those criteria left off your list. And they're not hard to build engineering-wise but permitting/environmental requirements mean they're still politically hard to build unless you're an Arab prince in your own country.
Wind and natural gas have worse political problems than solar.
Certainly they fit the particular criteria you mentioned better than nuclear. But I don't see why those should be the overriding criteria, especially if your preferred sources don't meet them either.
