I don't get why people here are so hyped. Why is it a good thing to completely dump renewables?

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.
-
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.
Nuclear can only perform as baseload
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.
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
Dosent sweden already have a fairly high and fairly stable energy production through their hydroelectiric power plants . Wouldnt it be better to just build more of those.
We do, but enviromental regulations pushed through during the past two decades is essentially preventing any new or expanded hydro projects. In fact, a lot of smaller hydro plants are instead being demolished due to being incompatible with these laws.
What? They are demolishing hydro plants? Do you have a source for that?
