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.

The only issue is they have not enough storage capacity for the excess.
That's a global problem unfortunately.
We do not yet have effective and economical means of storing energy in grid scale quantities that are readily deployable near where that power is consumed.
It's a huge problem actually, the biggest one facing renewables like solar.
This is a problem I'd very much like governments to sink a bit of money into. Sure, we don't have 100% efficient energy storage, but we certainly have technology that does the job. Liquid air energy storage, fly wheels, thermal sand batteries etc, can be installed anywhere and are available right now. Not to mention pumped hydro if you have suitable terrain.
There's a lot of stuff that we could build, and honestly, we just need to build it, now, even if it's not profitable, or super efficient. There's a bunch of solar and wind around the world not being built, or curtailed because prices go negative when there's no one to store it.
The free market sucks. We need government intervention to do the things the profit motive won't.
We only need about 40% overall efficiency to beat the theoretical limit of fossil fuel counterparts.
( <40% car engine, ≈40% power station )
Absolutely not if we're talking about nation-wide energy storage. The world's largest STEP, Hongrin-Leman, Switzerland, which occupies a considerable amount of space, has only a capacity of 100 GWh, which represents less than 1h15 of the winter night consumption of a country like France which consumes 70 GW at that time.
It would take 10 to sustain one night without wind, as you can have several each year. Then we would have to fill them entirely in one day for the next night which is impossible.
And that's just for the problem of capacity, such a STEP generates less than 500MW of power, so it would actually take 140 STEPs of that size to provide enough power.
And we're talking about today, where most cars and heating are still fossil-fueled and need to be replaced by electric.
Unless you find a technology that is now a miracle, running a country on solar and wind without hydro-electricity or nuclear is science fiction.
