Culture War Roundup for the week of April 10, 2023

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.

I caught this exchange after the previous thread had mostly closed, and I'd like to push back on the claim a little.

BinaryHobo:

I remember talk about just using the excess power to pump water up hill during the day and running it through turbines coming down at night.

Did anything ever come of that?

The_Nybbler:

The physical conditions necessary to make hydro storage practical aren't common.

(How do we do the fancy quotes with user, timestamp, and maybe a link? It'd be useful here.)

It's true that hydroelectric power sources, as in dams, have saturated the supply of naturally-occurring American sites. You need a river in a rocky valley, and there are only so many of those to go around, and once they're used up, it's very hard to create more of them.

What haven't been exhausted, and in fact what can be readily found or exploited, are height differentials in general. Hills, mountains, exhausted mines, deep valleys with no water supply, all offer significant height differentials, are naturally occurring, and can be readily built out into large-scale closed-loop pumped-hydro storage, with a closed reservoir at one extreme and a closed reservoir at the other, and a reversible turbine to generate potential energy in times of excess and power in times of deficit. Should those be exhausted, off-shore dropoffs are an enormous resource of the same, at the cost of more difficult installation and operation in every regard. And if we exhaust THOSE, water towers at sea or underground reservoirs on land can be constructed as well.

All of this, of course, is dumb and America should just take the leash off nuclear, as argued here. (I've not read it yet, but I expect it to make the points I would inline here.) That we haven't yet is a shame and a testament to our collective idiocy and Puritan hangover.

To back up you're pro-nuclear blurb, I would be way more worried (though still not particularly worried) about living underneath a pumped storage facility than next to a nuclear power plant. There have been multiple dam failures with death tolls in the thousands, much worse than any nuclear power disasters.

In terms of tail-risk, hydro is probably the most dangerous form of power around. There are dams around the world that could kill hundreds of thousands of people if they failed.

Another rarely discussed downside of hydropower is that it is extremely environmentally and socially destructive. Damming a river basically destroys its ecosystem. Dams also often flood very large areas, requiring people to evacuate and destroying anything that was there, natural or manmade.

For example, the Itaipu Dam:

When construction of the dam began, approximately 10,000 families living beside the Paraná River were displaced because of construction. (...) The world's largest waterfall by volume, the Guaíra Falls, was inundated by the newly formed Itaipu reservoir. The Brazilian government later liquidated the Guaíra Falls National Park. (...) The Guaíra Falls was an effective barrier that separated freshwater species in the upper Paraná basin (with its many endemics) from species found below it, and the two are recognized as different ecoregions.[18] After the falls disappeared, many species formerly restricted to one of these areas have been able to invade the other, causing problems typically associated with introduced species. For example, more than 30 fish species that formerly were restricted to the region below the falls have been able to invade the region above.

The construction of the Aswan Dam in Egypt flooded 5,250 km^2 and resulted in the relocation of 100,000 to 120,000 people and 22 Ancient Egyptian monuments.

For comparison, the Chernobyl Exclusion Zone has an area of 2,600 km^2. That is to say, the Aswan Dam rendered uninhabitable twice as much land as the Chernobyl disaster.

That's just one of many reservoirs all over the world. Looking at this list, if we exclude the reservoirs that resulted from the enlargement of pre-existing lakes and consider only the ones that are completely artificial, there are 15 reservoirs which individually rendered uninhabitable more land than the Chernobyl disaster. The total amount of land flooded by dams is many times greater than the Chernobyl Exclusion Zone. I don't have the exact figures, but the number of people displaced by dams is certainly also much larger than the number of people who were evacuated from the Chernobyl area.

Don't forget that this is a normal and accepted part of building hydropower, whereas the Chernobyl disaster was a one-time event that resulted from a combination of poor Soviet design and human error. If we considered the failures of dams, we'd get a death toll much larger than any estimate for Chernobyl.
