Solar now being the cheapest energy source made its rounds on Lemmy some weeks ago, if I remember correctly. I just found this graphic and felt it was worth sharing independently....
No it doesn’t. Cheap solar is great but even if it was $0, you’d still need some other tech to provide electricity when the sun is down. So it’s either gas, batteries, nuclear, etc. but you can’t just use solar alone.
And until batteries get good enough, nuclear is the cleanest option we have.
You do realise solar and wind gets pricier and pricier to integrate as the level of steerable capacity decreases?
What you are looking at here is “cost to install ‘rated capacity * load factor’”. A big part of the reason renewables are still cheaper is that we have a lot of backup steerable capacity, mainly in the form of gas plants in the west and coal plants everywhere else.
Renewables dump electricity onto the grid and then say “here, buy this!”. And the only reason the grid can respond and say “sure” is that it can tell the steerable gas and coal plants “turn off for a bit, these other plants are dumping a crap tonne of capacity onto the grid”.
Given the insane challenge in building enough storage and/or enough transmission capacity, you are going to need some steerable capacity beyond 70-80% renewable to continue to have cheap integration of intermittent renewables. Do you want that to be based on fossil fuel?
If we wanted to treat renewable capacity in the same way as we have treated other generators, we should say “I want steerable capacity between 0-1200 MW” from this field of wind turbines!”. That would force the currently externalised cost of guaranteeing generation onto the builders of renewables.
Right now, a lot of the real cost is hidden elsewhere in the grid - so it’s no wonder it looks so cheap.
Please don’t misread my comment as being against renewables, which we need a lot more of. I’m against crappy accounting.
However, your point also goes ageinst nuclear as this technology is not really steerable either. It produces a base supply. The lack of quick control of nuclear plant output even led to highways beeing lit in the night in Belgium (way back) to burn off the over supply.
The only technologies that can be quickly adjusted up and down are, to my knowledge, gas, hydro an battery storage. In a strictly renewable scenario (0 fossil, 0 nuclear fisson) it is imperative to have a lot of controllable reserves. Currently the plan is to use a mix of (pump) hydro, h2 and biomass powered gas plants and batteries in all shapes and forms (li-Ion, reflow, heat…) to be able to compensate peaks. This all is way more costly than just using wind and solar and hope supply will always be higher than demand.
For those interested I always recommend the yt channel “just have a think”. It has really awesome content about green technologies and the current state of affairs concerning the long and hard journey to 0 carbon.
This is a very interesting rabit hole you sent me into. Thanks for that!
Btw. I don’t get why you’re beeing downvoted. This is a civilised discussion and your comments are fair and well presented!
I started searching a bit about steering nuclear.
So as usual it doesn’t seem to be quite so simple. I found a paper from 2017 (in German publikationen.bibliothek.kit.edu/…/121070976 ). interesting parts translated through deepl/chatGPT:
“The operating manuals of the NPPs show that they [nuclear power plants] exhibit considerable flexibility:
In the range close to full load (above 80/90% of the nominal Power), the output can be increased or decreased by up to 10% of the nominal output per minute. In the upper load range (above 50/60 % PNenn), the power plants can be regulated at 3.8-5.2 %/min (for some reactor types, this is reduced to around 1 %/min if individual fuel rods are defective).
For comparison: In lignite-fired power plants, this value is around 3 %/min, 4 %/min for hard coal-fired power plants and 6 %/min for natural gas steam or combined power plants 6 %/min. Only gas turbines, at 12 %/min, are significantly faster.
The lower load range (between 20 and 60%) is also possible, but in discussions with power plant operators it became clear that this has not yet been used in regular operation (apart from start-up and shutdown operations) and is not used in regular operation.”
Also it seems that changing output puts stress on the whole systen. As well cited from the paper:
“Another factor is the number of cycles that the plants can undergo. Each load cycle stresses the material and, with frequent repetition, leads to signs of material fatigue. Nuclear power plants were designed for a specific maximum number of cycles during their construction. In the upper load range – for example, a reduction in power from 100% rated power to 80% and back (100-80-100) – coolant temperature and pressure hardly change. Therefore, the power plants are designed for up to 100,000 cycles of such nature. However, in the lower load range, the alternating stress on the components increases, and the maximum cycle count decreases significantly. The cycle 100-40-100, for instance, is allowed only 12,000 repetitions. For the cycle rated load-zero load-hot-rated load (100-0-100), a maximum of 400 cycles is specified. Assuming a plant lifespan of 40 years, this would correspond to 10 of these events per year.”
So there seems to be considerable flexibility but you don’t want to shut it off completely or run below say 50% of nominal power. Also start-up times from 0 seem to be very long (1-2 days). This might not be the perfect match for running together with renewables, but there are definitively possibilities. Even when it’s windy and the sun shines, renewables would need to be shut down and the more expensive nuclear plant would run and burn fuel.
Therefore, my opinion still stands: the ultimate goal should still be 0 burning stuff, 0 nuclear.

by not voting for Biden the reality is you’re voting for Trump
The same ol tired played out "I am a delusional moron" argument.
1 + 0 does not = 2, dipshit.
The REALITY of the situation is that both parties are the same. Both parties are genocidal. Both parties are stripping away our rights one by one. Both parties are making the rich richer. Both parties are making the poor poorer. They are working together to do this and then turning to the American people and saying "we cant work together, UwU!"
By not voting for Biden or Trump, I am not voting for Biden or Trump. Period.
I suggest others follow suit until we have vote worthy candidates, but I understand, morons like you are too addicted to the flavor of your parties boots.
I am voting disenfranchised. I am refusing to give Biden or Trump my voter turnout to advance their agenda.
I am making the only move that can force the end of the 2 party system.
I refuse to be a whiny little defeatist piss boy who votes for genocide and turns around and says "but they made me do it! There is nothing I can do about it!"
De-legitimize the 2 party system. Don't become a fascist to fight fascism.

As someone with 0 investment in this whole ecosystem, I saw and perused this article like a week ago, and my immediate impression was “Why is this guy constantly saying ‘Wayland breaks XXXXX’? Wayland isn’t breaking anything, it’s new tech. Wayland has certain features, or it doesn’t or doesn’t yet. The only folks breaking anything are those swapping use of X with Wayland, within various apps or tech stacks, potentially prematurely, where Wayland doesn’t yet have the full set of features needed.”
Whoever this is seems to have a really poor understanding of long-term software development, despite being way more invested in it than I am.
That step they don’t have to go makes me think with Windows 12, the whole process will likely start from 0. They will try to implement everything again, waiting for courts or politics to take some decisions after years.

I’m so confused on how rollout happens. Is it random? I’m in a first world country (not the USA), using Firefox and Ublock Origin and have never experienced the popups. I use YouTube daily, often watching 10+ videos a day, and have never seen an ad or the popup. I have also never done anything to update my extensions or purge the cache as you mentioned. I’ve just had 0 issues. On mobile, I use Newpipe (BraveNewPipe, a fork with sponsorblock) and once again, 0 issues.

0 chance. The SPD agrees, the CDU agrees, most of the AfD except the very nazi ones agree, the FDP and the Greens agree enthusiastically and likely even the Left Party is likely to have a sizeable amount of people voting for. Probably only the BSW (the left wing conservative splitter party of Sahra Wagenknecht) will vote against.
nun, von der Fantasie müssen wir uns wohl genauso verabschieden, wie von dem Traum, dass mit den letzten großen Migrationswellen eine große Zahl gut ausgebildeter Fachkräfte ins Land gekommen sei. Für den Ukraine-Krieg mag das noch eher zutreffend sein, aber insbesondere 2015/16 war das im Wesentlichen ein Beruhigungsbonbon, von dem am Ende des Tages nicht viel übrig geblieben ist.
Auch hier ist es wieder ein strukturelles Problem. Es werden Abschlüsse pauschal nicht anerkannt, oder die Anerkennung erfordert sehr viel Bürokratie, wenn denn die Unterlagen noch da sind.
Es mag auch sein, dass jemand der als Elektriker in Syrien gearbeitet hat, nicht direkt als Elektriker in Deutschland arbeiten kann. Aber dann muss man doch nicht die Ausbildung von 0 beginnen, sondern kann z.B. einen Schnellkurs für rechtliche Themen, DINs u.ä. machen und mit einer Abschlussprüfung die Gleichwertigkeit der Ausbildung bescheinigen. Dann gibts statt 3 Jahre Leerlauf nur ein halbes Jahr.
Was heißt rechtspopulistischer Beißreflex?
Als eine Modernisierung des Einbürgerungsgesetz vorgeschlagen wurde, hieß es sofort, man dürfe die deutsche Staatsbürgerschaft nicht “verschenken”. Ging zwar darum, dass die Leute immer noch nachweisen müssen, dass sie in Deutschland ihren Lebensmittelpunkt haben und integriert sind, aber wenn man dann 5, statt 8 Jahre warten muss, ist das ja wirklich fast schon verschenkit…
Genauso wurde gelogen, es gäbe hundertausende, die abgeschoben werden müssten. Jetzt stellt sich raus, es geht nur um 20.000 und selbst mit dem großen Tamtam, wird man die nicht schaffen. Darfür will man aber das Recht, nachts Wohnungen zu stürmen, was eine massive Einschränkung des Rechts auf geschützte Lebensbereiche ist. Hier geht es also wieder nicht darum, das erklärte Ziel wirksam zu erreichen. Denn das tut man damit einfach nicht. Es geht aber darum, Menschen zu entrexchten und zu entwürdigen, ohne dass es dafür einen realen Vorteil gibt. Das ist rassistisch motiviert.
Wenn allerdings die Gefängnisse hier immer noch besser sind, als das Leben in Freiheit in der verlassenen Heimat, dann fällt der präventive Strafzweck weg, sodass es in der Hinsicht keinen ausreichenden Anreiz mehr für ein rechtskonformes Verhalten mehr gibt.
Sorry, aber das ist Blödsinn. Niemand flieht nach Deutschland und nimmt lebensgefährliche Reisen auf sich, um dann hier im Gefängniss zu leben. Gute Haftbedingungen sind keine Motivation Verbrechen zu begehen, weil man immer auch unter guten Haftbedingungen immer noch unfrei ist. Da kann dir auch jeder Häftling sagen, dass das Scheiße ist.
Und dieser Betrachtung fehlt der Zusammenhang zu den Ursachen von Kriminalität. Wenn man nicht legal arbeiten darf, aber z.B. seine Schulden für die Flucht abbezahlen muss, dann wird man vor die Wahl gestellt Drogen im Park zu dealen, oder getötet zu werden. Da ist natürlich auch wieder richtig intelligent, dass man die Leistungen für Leute kürzen will. Damit wird bewusst und gezielt Kriminalität gefördert, auf der man dann die Abschiebung begründen kann.
Das ist alles rassistisch motiviert und wieder von vornherein erwartbar, weil die sozialen Effekte und zusammenhänge längst bekannt sind.
Das hat mE aber nichts mit Populismus zu tun, dass ist eine reine Betrachtung der Faktenlage und daraus resultierenden Konsequenzen.
Eine sehr selektive Betrachtung, von sehr stark interpretierten “Fakten”, wobei die Auswahl vom gewünschten Ergebnis abhängt. Also ist es bestenfalls dummer Populismus. Leider sind Lindner, Söder, Aiwanger, Weidel & co. aber viel zu intelligent, um nicht genau zu wissen, was sie tun.

Well, I grant you that it’s indeed complex if you look at the Westbank. But with Gaza and the Hamas? Hell no. Hamas main objective is wiping out the Jewish people. If Israel were comparable to them, then they’d not waste any time with carefully taking over the city, they’d just dump napalm on it and reduce the population to 0.
Ich geh nach Deutschland pruefungen in verschiedene Staedten zu schreiben. Das Essen von Restauranten sind teuer, und darum moechte ich fragen, ob es moeglich ist, von Mensa als nicht studenten zu essen.
Bei uns war (vor ein paar Jahren) 2,20€ das günstigste, ist dann aber auch meistens Pommes mit diversen Arten von Fleisch und als Nachtisch einen Pudding oder so. Heutzutage koche ich nur noch selbst und habe da je nach Gericht einen Fleischanteil von 0-20% und eine sehr viel breitere Auswahl an Gemüse als Kartoffeln. Ich bin jetzt aber auch knapp über 30 und vertrage Essen wie in der Mensa nicht mehr so gut, das liegt mir immer so schwer im Magen. Aber mit Anfang 20 konnte ich mir sowas gut jeden Tag reinziehen und war froh günstig warmes Essen zu bekommen.

Sure, systemd does what it is supposed to do. It is NOT bad design from the admins perspective, but from a os-architecture perspective. It is a huge single binary with a huge number of 0-day exploits (you can check those). The scale of the projects causes many possible exploits. A set of small programs, which do only one thing, is easier to maintain (^= decentralization of os-design)
