This is pointless: Scotland is already self-sufficient on renewables. What we need is a new grid interconnect between Scotland and England so we can export our surplus energy to the south!
It's all about the lobbyists, of course:
"Its ambitions for up to a quarter of all electricity to come from nuclear power by 2050 are being led by government-backed body Great British Nuclear." (Who?)
@cstross Nobody is self-sufficient on »renewables« (if by that you mean solar+wind). When the peak of solar+wind generation hits the demand line, the downs and ups mean that they meet only about 40% of live demand. Everything else must come from storage or other »backup«.
And nuclear energy is one of the best backup solutions there is. (So much so that it begs the question why only backup, but that's the fear of the renewables-only lobby.)
That point of just-met-demand is not an ideal or proposal, but a plausibilization case. It is the point up to which solar+wind scale roughly linear.
Yes, after that point comes overbuild plus storage. Every MW of that overbuild must be matched by storage with the same power output and hours or days of energy capacity. And every MW of that overbuild is diminished by storage and transmission losses. So, this point is like a sound barrier for ROI.
@cstross@Bern Not really. The build cost of each model fall build-by-build, even if the FOAKs seem always more expensive (which has reasons).
The biggest hurdle now is restarting the building industry, but that is actually happening. And it's already politically feasible in many european countries.
And these hurdles are all not fate-given, intrinsic, unchangeable. They are challenges to overcome, not /if/ but /how/.
And in the end, it's all just cherry-picking of details that might look bad, when the overall positive outcome is so blatantly obvious and demonstrates that the difficulties could already be overcome 40 years ago.
@bjn@cstross@Bern It is known how much the Messmer plan cost overall. It is less than half of what the german »Energiewende« cost /so far/, and the difference is that the Messmer plan actually had an effect. That is the main point.
The side show of individual cost points: I distinctly remember a graph showing how each series was more expensive than the one before, but each reactor within the series got progressively cheaper, but I'll have to re-find it. Either way no argument for/against.
@bjn@cstross@Bern You can't extrapolate what solar and wind cost now, at low grid penetration, to what it costs to build a complete grid on it. And no one has ever done that.
China builds nuclear in 5 years and 5 G$ per large reactor on time, on budget. I refuse to believe that we are worse at engineering. The question is how to create the political and financial environment that makes it possible, not how to find excuses not to do it.
Do it on top of solar+wind, no reason to stop that.
Worst downsizing I ever went through (short of "company is bankrupt, go home") was 10%, and that fucked our operational efficiency for a quarter. Spotify laid off 17% and are suffering. The C-suite were fools to assume there was 17% slack in the system, much less that middle management would choose the right 17% to fire (or that competent workers wouldn't see this coming and jump ship to better jobs, leaving time-servers behind). https://toot.cafe/@baldur/112325661237678117
@frameworkcomputer By the way, I always wanted to ask: it seems to me that a standard extension thingie has place enough for two USB-C on the outside. Could that be done?
Die schnellsten 10 Jahre Kernkraftausbau haben etwa soviel Leistung wie die schnellsten 10 Jahre Sonne+Wind-Ausbau hinzugefügt, nur 30 Jahre früher.
Das ist nur die Nennkapazität.
Es besteht keine Konkurrenz zwischen dem, was Sonne+Wind leisten können und Kernkraft, sondern zwischen Kernkraft und dem, was Sonne+Wind /nicht/ leisten können (also dem, was angeblich irgendwann mal Batterien und Gaskraft erledigen können sollen).
@burger@sixtus Der Betrieb von Kernkraftwerken ist pro produzierter Energie das billigste, was wir haben. Einfach die Kernkraftwerke weiterzubetreiben statt Geld für Kohle und Gas ausgeben zu müssen hätte Milliarden gespart, die man für alles mögliche sinnvolle hätte einsetzen können.
Das einzig teure an Kernkraft ist der Bau, und auch das relativiert sich.
Und was an Geld so alles vorhanden ist, wenn man will… man wundert sich. Doppelwumms!
@wonka@sixtus Nochmal: der Erhalt der Kernkraftwerke hätte /Geld gespart/, weil Kohle und Gas viel mehr kosten als der Betrieb von Kernkraftwerken, inklusive Wartung, Brennstäben, Getriebeöl, Putzlappen, und dem Hundefutter für den Chihuahua vom Wachdienst.
Das sind alles nur vorgeschobene Ausreden, weil man nicht WOLLTE.
Das ist so, als ob dir jemand, der zum Einkaufen lieber mit dem Auto statt Fahrrad fahren will, anfängt, den Kettenverschleiß, Ölverbrauch, Bremsabrieb und generelle Gefährlichkeit des Fahrrads vorzurechnen.
@wonka@burger@sixtus Nein, die PSÜ ist eine Untersuchung alle 10 Jahre, was man noch besser machen könnte, das hat nichts mit „Bestehen“ zu tun. Die tatsächlichen Sicherheitsüberprüfungen (analog zu sowas wie einer HU) liefen immer parallel jährlich mit und gaben keinen Grund zur Beanstandung.
Das ist nur ein Beispiel von den ersponnenen Ausreden.
@wonka@burger@sixtus Lies bitte erstmal den ersten Absatz nochmal ganz genau, inklusive Verstehen.
Das ist keine Überprüfung der Anlagen, sondern eine Überprüfung des Designs und der SOPs, ob man sie /noch verbessern kann/. Das passiert ohne daß man irgendwas an der Anlage selber technisch „überprüfen“ muß, das ist quasi „Papierkrieg“ (nur halt eine sinnvolle Art davon).
Sich davon gehindert fühlen zu lassen, ist hanebüchen.
Wer solche fadenscheinigen Ausreden braucht, hat keine Argumente.
Hybrid Air Vehicles announced it has agreed terms with Doncaster Council, based in north central England, for a production center at Carcroft Common outside the city to build the 92 meter (302 ft) long Airlander 10 aircraft:
Damon Texas solar farm turned into scrap metal by a on 23 March 2024. The cause was a mere… hailstorm.
Depending on which of the projects this is, this means local grid had just lost 2-5 MW installed power overnight and most panels will need to be replaced.
I assume this is one of the Damon TX SolarCollab projects. Can’t find any details on what kind of specific PV technology they’re using but if it’s CdTe they could also have cadmium leaching problem at this stage.
@CelloMomOnCars No, the state involvement is reducing the cost of finance, through better models and state-side guarantees. Around 60% of the costs of a large installation are costs of finance (i. e. interest), and most of the financial risk is just political. Paving the way through legislation and financial engineering doesn't cost the proverbial (mythical?) tax-payer anything.
