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 don't know natural disasters and war causing it to screw up also tends to worry people. Last time I checked wind and solar don't create massive damage to the environment when destroyed.
Except wind and solar don't have anywhere near the density we need. Nuclear plants are about 1kW/m^2. Wind is 2-3W/m^2, solar is 100W/m^2. Siting wind and solar projects can be just as damaging.
I didn't even mention tidal or geothermal. But how are any of those just as damaging? Nuclear waste is still a issue and again if it were attacked or destroyed would cause a massive ecological issue. Again last I checked destroying a wind, solar, tidal, or geothermal generator would not release radiation. Also the time to build one of those compared to a nuclear plant is a lot less last I checked.
Tidal is not a proven technology. The ocean environment is incredibly harsh on equipment. High-temp geothermal power generation is extremely site-specific, though ground-loop technology for heating and cooling is a proven technology that is woefully underutilized (though there are big challenges there as well, since ground loops take up space and done incorrectly overheat the ground temp/water table, etc.).
How would you define tidal as proven? Also correct there is no one solution for all areas. Unless you built a massive solar panel array around the planet I guess.
Which would solve global warming on its own
Producing wafers for solar panels is indeed one of the most ecologically damaging activities we can engage in. Have you ever been to a semiconductor fab?
Solar does not mean just solar panels. There are methods of using solar without them. Also what about wind, geothermal, or tidal?
What else does it mean, CSP? I'd love to see more CSP projects, but it's not where most of the investment is. Wind, as I've pointed out, is even less space-efficient than solar. And geothermal also isn't seeing the same investment dollars. It should. Tidal power is interesting, but good luck with the fishing lobby. My state has the first commerical offshore wind farm in the US, and it continues to receive significant backlash from the fishing industry. This isn't nearly as invasive as tidal might be.
And this is to ignore the elephant in the room, that without nuclear, we will not get away from fossil fuels soon enough. We don't have the technology to solve the base load problem with renewables yet. Making plans based on some assumed cadence of progress is a recipe for disaster. Storage is a hard problem, and batteries are such a dirty, shitty technology.
It's a lot easier and cheaper to build a solar plant of ten times the seize compared to one nuclear plant though.
How did you get those numbers though? A standard on-shore wind turbine has a maximum power output of 2MW. Let's say on average, it's half, so 1 million Watt. You're counting 500k m² per turbine?
What kind of area did you use for the nuclear plant?
Also, solar has the added benefit that it can be installed on basically wasted space (e.g., people's roof) unlike the others.
