average price throughout the whole day

Oh, right, that’s the important bit. Solar glut can’t increase the instantaneous price but its effects on average (mean?) price are less clear

3Samuel Hapák
No. Average price must go down. The evening price might go up—it might go up even to the level where the average price doesn’t change at all, but it can’t go up to the level where average price would rise. Think about it. You run a nuclear plant. Suddenly, due to solar competition, the day price went to 10%. You can’t turn nuclear off just during the day, so you keep it running and lower your day price to 10% as well. Your costs didn’t change, so to keep the same level of profitability, you need to rise the night price to 190%. This way your revenue doesn’t change. There is no reason why you would be able to rise the price above that level.

What's the point of building a solar farm when the grid is already flooded when the sun is shining?


Batteries, yes, but also, the sun is non-binary! Additional solar/wind capacity won’t generate power in still conditions at night, but slower winds and overcast weather and low evening sun all will, and depending on the relative price of solar (increasingly cheap) it may be optimal to oversize solar such that you have absurd overcapacity at summer noon, but require less (relatively expensive) storage (paraphrasing Tony Seba)

2AnthonyC
Yes, at conferences I've been to the discussion is increasingly not "How will we afford all the long term energy storage?" so much as "how much of a role will there be for long term energy storage?"  Personally I'm fairly confident that we'll eventually need at least 4-16 hrs energy storage in most places, and more in some grids, but I suspect that many places will be able to muddle and kludge their way through most multi-day storage needs with a bunch of other partial solutions that generate power or shift demand.
greylag20

solar actually makes power more expensive because you still need all the non-solar generation after the sun goes down but you leave it idle during the day


How can you possibly make something more expensive by producing a glut of it? Making prices more variable, yes; making plant that has been optimised for baseload less well optimised for its new job, sure.

5transhumanist_atom_understander
I seen the argument made by Robert Bryce and Alex Epstein, who don't suggest economic models, but the reason it's at least not obvious to me is that we need to consider supply, demand, price as functions of time. Solar produces a glut of electricity during the day. It makes sense to me that it would increase the price of electricity in the early evening, when solar isn't generating but demand is still high. It would do so by reducing the profitability of building natural gas plants to supply those hours, which results in either fewer natural gas plants (if demand is elastic) or the prices rising until they're profitable (if demand is inelastic). How this affects the average price throughout the whole day I don't know.

Priming, since debunked

The more dramatic “talk about getting old to people and they’ll walk slower” examples were debunked. The more pedestrian examples, as with word-association, “appear to be well-established” (https://www.science.org/doi/10.1126/science.345.6196.523-b), judging by a few minutes’ examination of Wikipedia (which common-sense supports: trying to NON-word-associate, as with certain panel & improv comedy games, is strikingly difficult)

What happens when macroeconomists mass-produce epicycles? You get DGSE models which would take thousands of years of data to train (https://arxiv.org/pdf/2210.16224.pdf).

Didn't Shalizi's paper you cite trying to school the economists turn out to be wrong and irreproducible due to source code bugs? He hasn't updated his post appendix on the matter despite saying 2 years ago that the fixes would be quick and he was sure the numerical results would still prove the point.

How does knowing about Ukraine’s draft affect an NYT reader’s opinion of the war? I mean it’s not going to be like

  • Reader: “Ukraine’s justified in defending itself from Russia!”
  • NYT-whistleblower: ”But Ukraine drafted soldiers to do it, and the NYT didn’t tell you!”
  • Reader: ”Oh, well, screw those guys, Ukraine should lose!”

… so what is it like?

Some ways a reader could respond include:

  • More instinctive patriotic fervour (Glory to Ukraine’s presumably-voluntary heroes!) (… and this seems like the likely propaganda angle in question)
  • Increased salience of hellishn

Steelman: If you mistakenly assume that all Ukrainian soldiers in this war are volunteers, it would mean that X people oppose the Russian invasion so much that they are literally willing to risk their lives to stop it. When you learn that actually most Ukrainian soldiers are drafted, you should decrease your estimate of X. (Yes, some of those soldiers really want to defend their homeland; and some of them kinda want their homeland to remain independent, but would prefer to increase the chances of their own survival; and finally some of them actually want to become a part of Russia, but are forced against their will to fight against.) Ukraine being a "hybrid regime" and Zelensky being not very popular right before the war is indirect evidence that many people might oppose the official policy of resisting Russia, and that Ukraine might be the kind of country that would send them to die by thousands regardless. For an American reader, assuming that all Ukrainian soldiers are either professionals or volunteers would be an easy mistake to make. NYT is lying by omission by not mentioning this fact (frequently enough). The expected reaction of a reader is probably something like: "I assumed, based on the number of soldiers, that opposing Russia is very popular among the Ukrainians... but now I realize that those soldiers were literally forced at gunpoint to go fighting, so this is actually not evidence of a popular support... now I have no strong evidence either way, and maybe the fact that NYT was manipulating me in a certain direction should make me update in the opposite direction... so the conclusion is somewhere between 'Russia is right' and 'we actually don't know who is right', and in either case we should stop interfering." . This of course works better if the reader has no other information about Russia and Ukraine. Then again, that might actually be the case for a typical NYT reader.

You know the rules, and so do I

I am confused. None of these are particularly social-status-improving, or, for that matter, social-status-worsening, because none of them are conspicuous. If you buy a tailored suit or an expensive car or an expensive house, people can see that you own it, and the extravagance signals wealth (or can be interpreted as materialism or lack of prudence); none of the things on the list seem to qualify. What am I missing?

2Adam Zerner
Yeah, more visible things like suits and cars are more status-signaling than something like hiring a house cleaner. The latter could be status-signaling if it comes up in conversation, but I that's a little limited, and so I don't think they were great examples for me to focus on in the post. They're just what came to my mind.

Hm. Now I thought I’d heard of gender dysphoria/transgender/etc showing up in brain imaging (eg. https://pubmed.ncbi.nlm.nih.gov/26766406/) and while “develop like female brains” would be bounding happily ahead of the evidence, that seems at least like sporadic snorting noises from the garage in the night time

3ChristianKl
The fact that someone finds a brain pattern that describes gender dysphoria but thinks that brain pattern does not warrant the description of looking like female brain patterns, to me does not look like evidence pointing in the direction that gender dysphoria is associated with female brain patterns. Vul et al's voodoo neuroscience paper is also worth reading, to have some perspective on these kinds of findings. 
7tailcalled
I can't confidently make claims about all brain imaging studies as I haven't read enough of them, but as a general rule studies that claim to find links between neurology and psychological traits are fake (same problem as candidate gene studies, plus maybe also the problem of "it's not clear we're looking at the right variables") unless the trait in question is g (IQ). This applies not just to the trans brain studies, but also to the studies claiming to find the sex differences in brain structure (while large sex differences in brain structure do exist, the ones that have been found so far appear to be completely uncorrelated with psychological traits that have sex differences once you control for sex, so they do not mediate the relationship between sex and those psychological traits).

Answer by greylag30

If Epstein’s thesis is, broadly, “cheap energy from fossil fuels is awesome and climate change isn’t that bad”, weaknesses would be likely to fall somewhere under these, classified in increasing controversy:

  • Climate change might be worse than he’s positing. Particularly, climate is a global system we only partly understand, and our error bars for the effects of inadvertently perturbing it may be quite large
  • Cheap energy may be obtainable from non-fossil sources. Epstein is keen on nuclear energy (why?), but, as AnthonyC points out, solar & wind are getti

… climate change is not an existential risk… Earth isn't going to become Venus, or anything like that

 

Last I heard, the big question was what positive-feedback “tipping points” exist, and at what CO2-level they become triggered. This would give quite wide error bars on what average heating is caused by a given quantity of cumulative emissions. If we can burn all the fossil fuels, turn the rainforests to desert, and vaporise all the methane clathrates, and still not end up like Venus, that’s… reassuring, I guess

3AnthonyC
Doing all that would be very bad. Not Venus, but enough to greatly decrease Earth's carrying capacity for humans and everything else, for a long time. We really should want that not to happen. But methane clathrate release turns out not to be as rapidly self-reinforcing as once feared, and at this point there's no longer an economic or technological reason to think we'll need to keep using fossil fuels and cutting down rainforests long enough to get to that point. We're already seeing slowdowns in net deforestation, in part because in some countries there is net reforestation, though rainforests in particular are being lost faster in part because these exist mostly in less developed countries, but even then it's (2020 aside) slowing down.

I’m not too clear about what you just spoke. Is that a parable, or a very subtle joke?

aphyer142

If you're making false claims of your incomprehension, it's clear that you've missed the moral dimension. When you truly can't get what someone is saying, remember today and the games you were playing. It takes people effort to give added proof...and they won't put that in for the boy who cries wolf.

Or to take a stronger example, someone you deeply care about must be alive because you deeply love them, and at the same time you also know for certain that they are dead.

 

Isn’t this the “denial” psychological defense mechanism, famous for its role in Kübler-Ross’s five stages of grief? In the reality the unfortunate thing is true; the impossibility is in the mind of the observer tripping circuit breakers.

Second-Order selection against My Immortal

If you think we‘ve got too much Culture War, vote for people/policies/things that in your opinion will diminish the Culture War (give or take other values, obviously).

(This is a consequentialist argument)

5CraigMichael
That’s not possible. Imagine watching people a game play a game of tug-of-war between teams representing the left and the right, it’s like regular tug-of-war except the ropes can become infinitely long and at any point the members of the audience can jump in and join their favorite team if their side is losing (or can go at punch someone on the winning side if they’d prefer). When you say “pick the side of the tug-of-war that will stop the tug-of-war” it tells me that you don’t understand the game that’s being played. No one involved wants to stop it, and there’s a nearly inexhaustible set of audience members on either side. You need to stop people from participating in the intrinsically harmful game and get them to play a pro-social one. The only way you can do that is to say “I’m not playing in the tug-of-war” and if you get enough people to do that, you deprive the game of the resources it needs to continue and can change the game.

No-one will have the endurance to claim on his insurance / Lloyd’s of London will be loaded when they go! - Tom Lehrer, “We will all go together when we go”

I’ve yet to delve into it, but RethinkX - a think tank, doubtless with an axe to grind - take similar ingredients and produce a result pointing in the opposite direction: RE is cheap, storage is relatively expensive, so the optimal solution is RE overcapacity with storage filling the gap that remains, and volatile energy prices, often very low, sometimes quite high. A large gas- or coal-fired power plant is not at all optimised for this market, and they don’t advise you to own one. See, for example: https://www.rethinkx.com/energy-lcoe.

The need for backup dispatchable power means that even if RE were free, it would still not be cheaper, because you still have to have the backup dispatchable power stations

 

This is somewhat true for the capital cost of the backup/dispatchable plant, but not the operating cost, which includes fuel, and any notion of the cost of the emissions (whether via carbon tax, cap and trade, or notional non–financial cost) (and, as far as AGW is concerned, the emissions are the important factor here).

Upvoting for this insight.

5jmh
I do agree that the distinction should be made and should be known, and that the confusion around the interpretation be reduced. At the same time calling it an "insight" appears to be due to either that very confusion or ignorance of the actual subject matter. https://thesolutionsjournal.com/2016/02/22/a-short-history-of-gdp-moving-towards-better-measures-of-human-well-being/   (Note -- I take the meaning of "value" above to refer to the more subjective utility-type meaning and not simply the price value for accounting at some aggregate level.) Perhaps a more interesting question here might be why so many people, and specifically non-lay people who really should know better (professional economists, professional financial journalist, governmental staff and representatives), keep slipping into the error in framing/rhetoric if not flat out error in thought.

I like the warren & plaza description of bi-level communities for productive discussion. 'Garden and stream' seems to overemphasize wikis as a mechanism, when it's really about persistence & specialization for filtering (eg Usenet discussion groups feeding into FAQs).
3matto
That's a good point. Another way to look at the difference between Facebook and X would be that Facebook/Twitter/etc. lean heavily on self-expression. Very little of the content on those sites actually aim to contribute to something, like a dialogue or body of knowledge. I think this is why communities focused around specific goals, say, writers, weight lifters, or rationalists do not do their work over Facebook/Twitter/etc. Some might use those to stay in touch, but the serious work gets done on yee old phpbb forums and the like, where self-expression is not the main point.

The way echo chambers work seems to be popularly mis-explained.

How’s it’s explained: everyone you encounter agrees with you

How it actually works: everyone you encounter who you disagree with appears to be insane or evil. Next time you encounter someone who disagrees with you, you expect them to be insane or evil, causing you to act in a way that seems to them to be insane or evil. Iterate.

Informed consent is important. I don't recall being informed about accumulation in bone marrow or ovaries, or the risk of myocarditis or the risk of brain fog at the time I got my shots. Maybe some of these side-effects weren't known at the time. But that the vaccine didn't stay in the muscle and therefore might have systemic effects was news to me, and they're asserting that this was known at the time. I've been experiencing persistent palpitations recently. It had not occurred to me that this could be due to the vaccine until I watched this video. I believed the mainstream line that the vaccines are safe and effective. I still think they're effective. The evidence for that is very strong. I'm less confident that they're safe now. Confirmation bias is a serious concern when reactions are this delayed though. People develop health issues all the time for all sorts of reasons. If they're primed to think the vaccine could have long-term side effects, they'd probably attribute all sorts of things to the vaccine that are mere coincidence. So individual anecdotes are pretty weak evidence, but this noisy data is still worth collecting to see if any patterns emerge. On the other hand, if we've all been primed to think the vaccines are safe (and we have been), then we won't make the connection at all and don't even report the data, and this is one of the main concerns from the video. The issue has become too politicized for society to be objective about it. Legitimate concerns get you labeled as an antivaxxer.

Part of it is that high-performance solar cells require single-crystal silicon or gallium arsenide.  The purification process for semiconductors is extremely energy intensive.  The device fabrication processes are resource and energy intensive as well.  But yes, storage is also a huge problem (especially for winter heating, etc.)
