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.
-
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 mean let's be honest here, there's no way they did this because of an underlying police change.
I suspect they rather looked at other western countries trying to build large-scale projects and noticed how absurd the idea of building one nuclear reactor without a 15y++ delay was, nevermind 10 of them. Quietly drop it before someone checks whether it's even doable. 😅
Source: Am German, we are experts on letting our complicated building projects run completely overbudget and take multiple times as long as projected.
Sweden realized they couldn't join NATO if they invited Chinese expertise to help build a nuclear power plant.
The right choice. Nuclear would be a great solution if we went all in 40 years ago. But we didnt and now we need a solution as soon as possible, not in 15 years to build a plant or in 25 years when it breaks even, now.
It takes just 6 months to build a 50 MW wind farm https://www.edfenergy.com/energywise/all-you-need-to-know-about-wind-power#:~:text=Wind%20farms%20can%20be%20built,last%20between%2020%E2%80%9325%20years.
Sweden uses 130 TW/h per year (130000000000 KW/h) as of 2020 https://www.iea.org/countries/sweden
and about 25% of that is fossil fuels. as of 2017 https://www.macrotrends.net/countries/SWE/sweden/fossil-fuel-consumption
So they would need to replace 32500000000 KW/h per year to get off fossil fuels
But KW/h/y is dumb so lets just make it KW/h
3710045
Then make it MW (yes I know I converted from TW to KW to MW.) so
3710 MW needed to replace fossil fuels.
So they would need 74 50MW wind farms to match that.
If they wanted to do that in 10 years to be faster than building a single nuclear plant, they would only need to be building 4 farms concurrently.
and about 25% of that is fossil fuels.
Sweden uses essentially no fossil fuels in the grid - it's basically hydro, nuclear and wind for all of it. The small amount of fossil fuels used is stuff like burning plastics, and one oil plant that is turned on once in a blue moon when there's an energy crisis. It's national news when they turn that one on, and it's considered a huge failure every time it happens.
The real figure for fossil versus non-fossil energy in Sweden is 2% fossil versus 98% non-fossil, with hydro being the primary energy source (35-45%), followed by nuclear (30%) and then wind (20%). Source, in Swedish: https://www.energiforetagen.se/energifakta/elsystemet/produktion/
A few errors
- 130TWh is the final electricity consumption, not the generation. Since Sweden is a big net exporter of electricity, there is a big difference
- I'm not sure what macrotrends refers to by "Fossil fuel consumption", but it's pobably referring to raw energy rather than electricity (which doesnt consider conversion efficiency)
- In reality, sweden uses almost no fossil fuels in its electricity mix, and that is in large part due to nuclear
- KWh and KW, not KW and KW/h
- In your calculations you failed to account for capacity factors. Wind plants have average capacity factors of about 42% in sweden, so the capacity would need to be over double the consumption, even ignoring the variability of consumption and production
Nevertheless, I do agree that Sweden doesn't need more nuclear. It already generates some of the cleanest electricity in the world and I'd imagine fossil fuels are really only used for peak load.
Thank you for the corrections!
But KW/h/y is dumb so lets just make it KW/h
It's kW, not KW/h.
explain?
32500000000 KW/h per year
That's 32500000000 kWh/y
= 32500000000 * k * W * h / y
= 32500000000 * k * W * h / (365 * 24 * h)
= 32500000000 * k * W * h / 8760 / h
= 32500000000 / 8760 * k * W * h / h
= 3710046 * k * W * 1
= 3710046 kW
(You actually corrected yourself when converting to mW.)
Since watt is joule per second, kwh per year is one kilojoule per second per hour per year.
Electricians have played us like fools
kWh is kilojoule per second times 3600 seconds or 3600 kilojoule. kWh/y is 3600 joule per year or 3600 kilojoule / (24*3600*365) ~0.1W
A kW/h would imply that the power changes by that amount every hour, while a kWh is the amount of energy spent in an hour
Good. This entire thing was beyond stupidity.
BOOOOO
