Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in !yurop@lemm.ee. (They're cool, you should subscribe there too!)
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media. Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to any of the mods: @federalreverse@feddit.org, @poVoq@slrpnk.net, or @anzo@programming.dev.

The entire peninsula has no power at all? How on earth does that happen?

I hope everyone's safe.

We are. But thank you for the concern.

Electricity network requires that production and consumption are always equal. If there is too little production, the frequency (Hz) goes down and if too little consumption, the frequency goes up. If frequency goes too far every electric device pretty much breaks.

This is why there is automation in the network that tries to balance the network (reserve production and consumption). BUT if shit hits the fan, and frequency goes too bad, it automatically takes load off or production off the network. This often causes domino effect, you take load off, which causes over production, and again you take production off and loop is ready. In minutes the whole network falls like domino blocks, one by one.

There was lots of luck (and probably skill and preparation) that they were able to stop it. Main land Europe from Portugal to Turkey is one big network.

Cold starting whole Europe would have taken week. You need to start small islands, and connect them together slowly. Balancing load and production.

Europe has a highly interconnected grid. Usually that works in everyone's favor by providing much better stability than smaller grids. It appears there are ways to take down the entire grid too though.

Extreme weather phenomenon. Something about a wave reveberation.
