World News
A community for discussing events around the World
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.

Funnily enough, projects for green steel and the construction of new massive factories in Northern Sweden mean that the power surplus is expected to be gone by 2030. We need more electricity production, from all carbon neutral sources being built everywhere, ASAP.
Exactly. We need it quickly.
Renewables are here now and can be deployed quickly. Nuclear takes time and is often heavily delayed and over budget.
We need nuclear as well, but we need renewables first, to build capacity as quickly as possible. We need a huge excess of renewable capacity, to account for times when the full capacity isn't available. We shouldn't expect to be using the full capacity at any time.
Once we've phased out fossil fuels, then nuclear will be important. But right now nuclear only serves to sustain our dependency on fossil fuels.
Care to elaborate on this?
The two largest economies with the low reliance on fossil fuels for energy (Sweden & France) get significant portions of their energy production from nuclear power. Iceland relies on geothermal, and the others (Tajikistan, Switzerland, Costa Rica, Norway) have lots of hydro capacity, which are all excellent, but also largely dependent on geography.
I don't have figures to hand, but I'd gladly dig into them with you, if you have suggestions.
Sweden does have some amount of fossil fuel generation. The article claims 3 nuclear plants provide 30% of the country's needs right now, and says the target being set is for 10 new nuclear plants over the next 20 years. In 2045 (~20 years), demand is predicted to be double that of today.
If we assume all current nuclear plants will close and all new plants will be 20% larger, that means these 10 new nuclear plants will fulfill 60% of predicted demand in ~2045. Again, I'm happy to review actual numbers - I imagine most if not all of these 10 plants are at least in early design proposal stages, so there are some actual MW numbers to be crunched.
I think keeping Sweden's nuclear at about 30-40%, while investing more into a large excess of renewables, would allow fossil fuels to be switched off more quickly. This would still mean investment and growth in nuclear, with maybe 5 or 6 plants (if the 3 existing plants have to close), but would get rid of fossil fuels more quickly.
In maybe 10 years' time, with fossil fuels well and truly on their way out, that would be a better time to expand nuclear.
Our world in data has excellent stats on the topic, and I am quite familiar with the electricity production of Sweden (my home country). Excepting 2003 and 2010 (both quite cold winters) the share of electricity from fossil fuel sources has been sub 5% since 1997. Thus, for my own country I tend to look more at the share of all energy that comes from fossil fuels (currently 26%) rather than just electricity, but below is a chart detailing the shares of electricity produced by each category.
As you can see, investments in wind have been massive, adding 30 TWh of production (~15%) since 2010. However, in the meantime, nuclear energy has not only been neglected, but actively dismantled. Since 2010, some 15 TWh of production has been removed from the grid. Whilst this isn't an issue in isolation, import demands for electricity from continental Europe have increased noticeably during the same time period. In 2010, we had net 0 power flow, whilst 2021 saw a net export of ~16TWh (mainly to a country that completely dismantled their fleet of nuclear reactors instead of their coal power plants and shall not be named)
What this means is that in a decade, with a population increase of 10% and a GDP increase of 20%, electricity availability has actually declined, which is becoming a serious problem now that some of the most energy intensive areas of society are starting to electrify in earnest (transports and heavy industries).
Green steel is the perfect dispatchable load. The steps up until sponge iron require very little capex, with the input costs being driven by energy price it is a far better match for renewables.
Same goes for high temperature electrolysis.
The resulting iron stores 2-8kWh/kg with nothing more than a box as infrastructure (and maybe some oil or nitrogen to stop rust).
Both are so ideal as dispatchable loads that iron js seriously being considered as a fuel/energy carrier instead of hydrogen.
Then run the arc furnaces which are higher capex and labour cost but a fifth of the energy at a constant rate.
The idea of buildkng nuclear to run green steel is utterly deranged.
