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.

Cost-plus contracts are a Hell of a drug.
The whole project has been a huge unjust wealth transfer directly from ratepayers to shareholders, and the regulatory-captured Georgia Public Service Commission just let it happen.
(If I sound bitter, it's because I'm one of the ratepayers getting screwed.)
Shitty as that is, at least you're getting a reactor out of it all. I still support renewables over nuclear, primarily for cost-benefit reasons, but it's always good to have some diversity in the generation mix.
The big demand right now is a replacement for the capabilities of fossil fuels. There's a lot going on with energy storage tech right now.
We already had nuclear. This project was building reactors #3 and #4 on a site that already had two, and between that and Plant Hatch, nuclear was apparently already 23% of GA Power's energy mix even before these new ones came online.
Frankly, renewables would've been superior for energy mix diversity reasons, too. The fact that it would've also just been flat-out cheaper for Georgia Power to pay to install solar on my (and everybody else's) house just adds insult to injury.
(Okay, that last bit might be hyperbole -- I haven't done the math. But still...!)
Solar + battery would work for people who have houses but not industry or mid-high rises. The transmission grid doesn't just function as a means to get energy places but it connects everything in to one system as a means to stabilize everything. So when that electric arc furnace is turned on there isn't a brownout because the huge demand has been scheduled and generation can be dispatched accordingly. At the distribution grid which is the lower voltage lines connecting homes you can be a lot more creative with microgrid and feed-in-tariffs, in a lot of places these distribution lines are managed by local distribution companies/LDCs which operate separate from the Independent System Operator/ISO which operates the transmission grid and an energy market if there is one.
10 million people. $15k per solar installation. Eh, not too far off.
More than one person lives in a building generally. It's more like $15,000 to install 1kW of solar, so like $15B to install 1000MW, so you literally could have just about installed the solar capacity with just the cost overrun.
There's some hidden assumptions in there that aren't quite warrented.
First, when quoting output, solar tend to state their peak output at full sunlight. How much they actually put out depends on the area, but reducing the number to 20% is a good rule of thumb.
Second, you seem to be thinking of rooftop residential installs. Those are the most expensive way to do solar. In fact, levelized cost of energy studies show it's almost as bad as nuclear. Home installs have trouble taking advantage of the economics of mass production. Making a dedicated solar field is far more cost efficient. So much so that nuclear looks pathetic on those same levelized cost studies.
Gee, really? I never would have guessed /s
More seriously: It's very quick to search "population of GA", so that's what I did. If you have a different figure you'd prefer to use, feel free to post it.
Uh, what? $15,000 = $15k which is what I wrote. I'm not sure what point you're trying to make here.
Ok, $15k x 10M is just an order of magnitude too high of an estimate is all. I was just adding more context.
No, order of magnitude is 10x off. You can't massage the numbers enough to get there with any reasonable assumptions.
Obviously the average household size is not 10 people, but let's be generous and say that it's 5 people, so you're looking at 2 million houses. Rooftop solar installation costs between $10k and $30k per building. Frankly, in this context, $15k is generously low as a cost estimate.
Also, go back and re-read my original comment in this thread. The context was the idea of spending $30 billion on installing solar panels everywhere instead of building the nuclear plant. Flippant, sure, but -- actually, the numbers aren't far off even with these sandpaper-rough estimates.
The project started 10 years ago. Renewables were about to burst open and hit some incredible cost reductions.
This project looked good at the time.
