Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. 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. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

You could make the same argument for renewables though, and they're much, much more inexpensive.
Depends on many factors. Solar would be useful if the area had extensive terrain that could serve the city, however, in northern latitudes winter would be challenging with short days and low angle sunlight. If the situation allows, wind power could be useful, when the wind is blowing. The fantastic thing about these units is that they'll crank out the KW day, night, no matter the season or location. They are not restricted to large generator farms with the scale of upkeep and maintenance they require. A city could be isolated in challenging remote areas and be self sustaining for their energy needs. These aren't meant to be a "fix-all" solution for every situation, but they make tremendous sense in many applications where current methods are not ideal.
I get what you're saying but we really should move away from needing power to be generated locally. High voltage DC can move power across huge distances with minimal loss - https://en.wikipedia.org/wiki/High-voltage_direct_current
We don't need new nuclear in the US, we need the government to get off its ass and mandate an upgraded national grid so we can send power to wherever it's needed. We already have the perfect conditions in the south for solar and the midwest prairies for wind, as well as offshore. Couple those with storage and there really is no case for SMRs outside of them being a way for fossil fuel companies to justify continuing to kill the planet while we wait for "the next big thing in nuclear power".
Except long distance power transmission losses are not minimal. Depending on many factors, losses can easily be in the 5% - 10% range. With the amount of energy going through those wires, that's HUGE. The additional complexity and inefficienies of relay stations, all add up. Having worked in the power sector for nearly a decade, I knew engineers who were celebrated in being able to squeeze an improvement of tiny fractions of % efficiency, as that resulted in millions of dollars saved throughout the year.
Are you referring to AC or HVDC?
