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.

My guess is that in a climate like Germany's, solar isn't consistent enough to provide the steady baseline power that coal plants can.
One of the complexities of power infrastructure is that demand must be met instantaneously and exactly. Coal and solar typically occupy different roles in a grid's power sources. Coal plants are slow to start, but very consistent, so they provide baseline power. Solar is virtually instantaneous, but inconsistent, so it's better suited to handle the daily fluctuations.
So, in a place like Germany, even in abundance, solar can't realistically replace coal until we have a good way of storing power to act as a buffer. Of course, nuclear is a fantastic replacement for coal, but we all know how Germany's politicians feel about it...
We also know building nuclear takes 20 years and costs more than building thrice the capacity in renewables + Germany has no long-term nuclear storage, only temporary one's a la Simpsons.
Germany had 17 active nuclear plants in 2011 and decommissioned them all by 2023.
They were already past their expiry date. Germany would face the same shit France is facing with their old reactors.
You are correct that when you build one new plant every 25 years it takes a long time to spool the industry, the skills, the testing and the manufacturing capability up to build new nuclear.
In countries that regularly build new nuclear it takes 5 years, comparable to any other power source. When France when through their mass-conversion to nuclear in the 70s (following the oil crisis), they put 2-3 new nuclear plants into operation every year.
All new western nuclear is in “production hell”. We don’t build them often enough to retain the skill set or for industry to dare invest. So they become massive state-run enterprises.
If we were serious on solving our climate crisis we would build nuclear power plans en masse.
Coulnd't we use solar to pump water into reservoirs, and then let the water flow through hydroelectrical dams when we need the electricity?
[yes](> https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity)
Oh wow, I had no idea this existed. Awesome!
Wait Are these not common where you are?
We have a lot of dams, but I haven't heard that we were pumping water into the reservoirs.
We also don't have, like, fields of solar panels, as far as I know. I think it's too cloudy here. But we have wind turbines, especially in coastal areas.
I guess I meant not all of them and especially not at the same time but that wasn't clear in my first post. I understand that a baseline is needed but if during daytime they're generating excess constantly then shutting down a few wouldn't hurt. Especially since Germany is one of the biggest offenders in the world when it comes to coal. Storage is definitely a concern but in case of surges there's other power from neighboring countries that can help with the demand. Sodium ion batteries are looking like a good possibility.
