Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Hell yeah, tell me the best future isn't nuclear power and electric rail like an old space Lego set.
Nuclear's probably not a great long term choice since it's a lot more expensive than renewables.
But that's just the generated per kwh cost, not taking into account when the energy is generated. To compare a full renewables grid to a renewables nuclear mixed grid you need to take into account massive energy storage systems and their inefficiencies and possible material shortages. We can't just compare the currently favorable cost per kwh without taking into account problems as we scale into less reliable energy sources.
You will need long term storage in both cases. Nuclear can't act as a peaker because you can't quickly ramp up or down the generation. Nuclear can only perform as baseload which, in theory, could be provided by a renewable energy mix if the install base is high enough.
I don't disagree with your point that it isn't a simple direct comparison but any sensible energy mix will still require storage. I find it difficult to see the economic case for nuclear if renewables can be installed in sufficient quantities, given that nuclear is roughly 4 times as expensive as solar and wind.
That's only true for NPPs built decades ago. Modern designs can also do load-following power. For peaks you have renewables, of course, they complement each other. Diversity makes a healthy grid.
The plants that can allegedly do this almost never do, and most of them have had maintenance issues which cost more to fix than replacing them with renewables.
Niclear has high investment cost and very low production cost which incentivises runnig at max output for as long as possible. This might block out renewables from the grid if their production cost is higher and make it less profitable to build them. So its really not a Symbiosis between nuclear and regenerative
I think this is a maybe in terms of what the grid needs. Will be great if nuclear is built that genuinely supports system demands.
Couldn't agree more.
It's good that they can do it. Even better if they don't need to.
With 100% renewables you would need almost 100% storage and potentially for multiple days, with a nuclear baseload you'd only need storage for the peaks, you could even use excess renewables to charge up the storage for these peaks.
What do you mean with 100% Storage? And why would you need it for multiple days if you have a grid that transports energy all around the continent and in future possible worldwide?
I guess we can talk about transmission then, yes if you can get enough renewable energy across a continent then in theory you can transmit it to where it is needed, however you would need a LOT of transmission capability that is not currently available. The current interconnects can handle an impressive amount of load but you're not going to transmit enough power for all of sweeden from spain. There are some massive transmission projects underway that should help address this but they're still not going to be enough to cover a 100% outage for most places. So a cost analysis would have to be done to determine if massive transmission projects are better than building nuclear plants. Keep in mind, these same transmission lines can transmit nuclear power as well so they should be built regardless of what energy source you use.
can be build faster and cheaper than nuclear, doesn't need fuel and needs to be build anyway. We get the cheapest, strongest and least dangerous grid if we invest in more renewables, storage and better transmission. And that's something we can get done fast and start harvesting the profits in a few years.
I mostly agree except transmission is not cheap, and further I'm not convinced transmission across a continent is even possible even with crazy high voltage DC lines which currently don't exist. The current massive projects are going to take several years for just a few lines, it would take an insane ramp up in production to do the entire continent. While we're working on that nuclear can be built reasonably fast without political hurdles blocking every step of the way. That's not to downplay the need for recycling the waste which will need to be invented regardless because the waste already exists. I'm also not convinced renewables can ramp up production on a scale that would be able to replace in excess of 100% of the demand within a few years, but I guess I'll have to look that up. Your concerns about nuclear are valid, but rebewables won't magically solve all the problems of reliability and scale, we're going to need a baseload and nuclear has proven for decades that it can do the job.
High voltage dc transmission lines already exist and are already in use .
This is build faster and with fewer risks than nuclear.
Not sure about the 100% point but you will certainly need long term storage which is an unsolved problem. A point I wanted to make was that with enough renewables installed you have the baseload. You would also have an excess of production at peak times that would be useful to store long term.
My personnal view is that a sensible energy mix should have some nuclear but I don't think it is the key to solving our future energy requirements and should be minimal as it isn't good value.
Entirely unsubstantiated. Renewables require storage only for the peak demands, otherwise, they function as a baseload, provided that there is a sensitive balance of wind and solar power generation installations.
If you want 99.9999% uptime with no backup then the nuclear fleet will need months or years of storage due to the prevalence of correlated unplamned outages.
Back in reality, a good enough renewable system with >95-99% uptime has less than 10% of the storage that will be found in the accompanying country's EV fleet. Even if you are too allergic to nuance to understand the real solution for the remainder, simply planning a renewable rollout and assuming existing fossil fuel peakers for down periods over 12 hours will take 20-100 years to release as much carbon as delaying one of the years waiting for late, over budget nuclear reactors.
And thus you have shown that your mind is made up and no amount of evidence will sway your decisions. Good day.
I'm plenty open to evidence, it's just every time I look at some it shows a new lie that nukebros tell. Every single talking point isnutter bullshit to the pooint where if you look it up you find that nukes are significantly worse by whatever hair-splitting metric is being used ti try and distract from their main downsides.
There is a fully renewable solution for the 2-5 >100 hour events a year where battery storage is unsuitable, but it requires holding more than one thought in your head at a time (thermal storage, dispatchable load and w2e is one combo).
That's not very open minded. I'm all for vetting your sources and skepticism, but going in with your mind made up is close minded.
Look my dude, you're clearly here to fight not discuss, and that's fine we absolutely need to fight against the establishment, activisim is important. Fighting against your allies is a pro gamer move though.
That last bit is the rub though. I'm fighting to decarbonize and reduce exploitation kf resource rich countries and you're fighting to stop it.
The constant tirade of insane lies is tolerable. Pretending you're not on the side of fossil fuels is the incredibly insulting bit.
No, the insulting bit is youd constant tirade of insane lies, buttercup.
France, with all it's maintainance disasters with their nuclear reactors shows us yet another problem: how to properly cool the water for the generator? With sinking fresh-water levels in rivers and fastly rising water temperatures nuclear reactors become less reliable. Wind and solar output on the other side will in an ironical way get a little more reliable, as there will be more of both.
