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.

I thank the oligarchs and their willing consumption enthusiasts. This apocalypse is brought to you by unchecked, insatiably greedy capitalists and capitalism.
That's a false dichotomy. There are more power sources than coal and nuclear.
Also electricity generation is not the only source of emissions. Car traffic, cruise ships, aiplanes, all need to be reduced and can't just be replaced by nuclear power.
In theory, yes. In practice, nuclear plants that are shut off are almost always replaced with fossils, with the specific fossil fuel of choice often being coal.
Energy is not something where you can just pick one solution and run with it (at least, non-fossils, anyway). Nuclear is slow to ramp, so it usually takes care of baseline load. Renewables like wind and solar are situational, they mostly work throughout the day (yes, wind too, differential heating of earth's surface by the sun is what causes surface-level winds) and depend greatly on weather. Hydro is quite reliable but it's rarely available in the quantities needed. The cleanest grids on the planet use all of these, and throw in some fossils for load balancing, phasing them out with energy storage solutions as they become available.
You can't just shoot one of the pillars of this system of clean energy and then say you never tried to topple the system, just wanted to prop up the other pillars. Discussing shutting off nuclear plants without considering the alternative is pure lunacy, driven by fearmongering, and propped up by no small amounts of oil money for a reason.
Replacing nuclear with renewables is simply not the reality of the situation. Nuclear and renewables work together to replace fossils, and fill different roles. It's not one or the other, it's both and even together they're not yet enough.
So when you do consider the alternatives, moving from nuclear to the inevitable replacement, fossils, is still lunacy, just for other reasons: even if you care about nothing more than atmospheric radiation, coal puts more of it out per kWh generated, solely because of C-14 isotopes. Nuclear is shockingly clean, mostly due to its energy density, but also because it's not producing barrels of green goo, just small pills of spicy ceramics. And if your point is accidents, just how many oil spills have we had to endure? How many times was the frickin ocean set on fire? How many bloody and brutal wars were motivated by oil? Is that really what a safer energy source sounds like to you, just because there are two nuclear accidents the world knows about, and a thousand fossil accidents, of which the world lost count already?
And deflecting to other industries is also quite disingenuous. Especially if your scapegoat is transportation, since that's an industry that's increasingly getting electrified in an effort to make it cleaner at the same logistical capacity, and therefore will depend more and more on the very same electrical grid which you're trying to detract from.
Being from Germany, I have often read such arguments and at least here that is simply not true.
The decrease in nuclear power was accompanied by a decrease in fossil fuel.
Could that decrease have been larger if nuclear had been kept around longer? Possibly.
But if we are talking about building new power plants, the money is typically better invested in renewables. They're faster to build and produce cheaper energy.

I'm not sure what the point is.
German Electricity is dirtier than France's therefor no other sources of electricity exist beyond coal and nuclear?
That would be a weird conclusion seeing as both countries also use other power sources.
Germany, specifically, was one of the worst offenders in this category. They do renewables at maximum capacity (like everyone else) but there's still a massive gap to fill, and with issues of strategic dependence around hydrocarbons, the obvious answer to fill in the missing capacity was coal. Most of the time you get a mix of coal and natural gas, whichever is easier, but in Germany's case that mix was almost entirely on the side of coal.
And without abundant hydro power, or an energy storage solution that could store a full night's worth of energy even if the current deployment of renewables was able to generate that (which it's pretty far from), there aren't a lot more options. Germany's strategy to shut off its nuclear plants out of fearmongering has been a heinous crime against the environment.
When oil companies love your green party you know you fucked up.
I'm assuming the 'gap' refers to the reduced nuclear capacity.
So you're saying that Germany replaced the power previously generated by nuclear power almost entirely with coal power?
Do you have ANY statistics to support that?
The only actual increase in coal energy I know of was an unplanned short time rise due to the war in Ukraine and the loss of gas imports.
Edit: Also the original argument was that coal and nuclear is a false dichotomy. Your own comment mentions a mix of coal and gas, mentions renewables, so clearly there are more than those two options, right?
There is massive work being done to improve large scale energy storage (big batteries) so the renewables become less and less situational. Large scale energy storage is significantly less constrained than car batteries, because weight is a one time cost. Even gravity based batteries could become viable.
Also, in response to the previous commenter, electricity generation is by far and large the main source of emissions accounting for more than half, with more than a quarter being agriculture. Transportation is 14%, and given the future transition to electric vehicles, one might argue that half of that can be tack'd on to electricity generation's share. (Half because electric cars are more than twice as efficient at energy conversion than petrol cars. Toss in some power line losses and that's a reasonable estimate)
All of that is great, and I'm all for it. Can't wait for the first grids with no fossils whatsoever, once energy storage improves enough that it can take all the balancing load. When we reach that, it will mark the start of the era where nuclear is actually being replaced by renewables rather than fossils.
My point here is that switching off nuclear is premature for now. It's a very clean source of energy once you look at the per kWh numbers and nuclear waste management solutions are actually extremely safe. (The videos where they test the containers by smashing actual trains into them are kinda fun -- and those tests are done with liquid water, which is far more susceptible to leaking than solid ceramics.) Of course, if we reach a point where wind, solar, and hydro can fully replace fossils and start eating into nuclear's share then that's gonna be a very different conversation, and I'm fully with renewables in that situation, but we should always keep the alternatives in mind when we shut something off.
That's why we're not just shutting down coal plants altogether, because there's just nothing to replace them. Although an energy policy where you just flat out ban ~~renewables~~ fossils and tell the market that that's the supply, now go figure it out would certainly be interesting. Very expensive and terrible for the economy, but interesting nonetheless. (Definitely the based kind of chaos if you ask me.)
edit: okay, that was a weird word to accidentally replace, lol
There are more problems with nuclear energy, though. The biggest being that we burden future generations for literally thousands of years with a growing amount of waste. I am not sure why this is always missing from the discussions of people who are pro nuclear power.
It is making the same mistake again as we did before: creating a problem for future generations to solve. And in this case the problem is dire and, because of the immensely long timespan, we have no way to reliably plan ahead for so long.
Just make nuclear powered cruise ships, easy.
/s
Many Navy ships are nuclear powered. Aircraft carriers have multiple nuclear reactors, submarines are nuclear powered, and many cruisers are nuclear. There's also a lot of nuclear powered icebreakers.
They made exactly one nuke-powered cruise ship. It never made money.
I'm all for getting rid of the cruise ships. Floating land-whale-buffet reef-destroying pollution devices is what they are. I've seen firsthand the effect they have on Caribbean islands they make their destination, and it's never good.
Thank the good old Green Party of Germany! Restarting all those coal plants and shutting down nuclear reactors!
Yeah, I'll take a source for this one. Coal power generation has not increased in Germany whereas the Green party's policies in 1998 led to the first large scale deployment of solar energy in the world.
@Regelfall @Widowmaker_Best_Girl
would removing wind turbine to expand the coal mine count as a source ?

God, that's so depressing. I genuinely don't understand how we - any of us, in any country - are supposed to be okay with these political mechanisms filled with incompetent, out-of-touch, self-interested codgers. I'm not willing to take action, but when our entire world is being picked apart by the public sector and sold for parts by the private sector, what are we to do?
Do you really think governments actually gave a shit about some deluded hippies? Nah, they were just the scapegoats the politicians used to pretend they weren't in bed with the fossil fuel lobbyists.
