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.

Power being priced negative is awesome. We need more of it imo, make energy so abundant that it makes processes that were previously too energy-intensive viable, and enables a massive increase in both residential and grid storage capacity.
My opinion is that Na-ion batteries are the way for bulk grid storage and apartment/home storage nya.
They use hyper abundant materials and are now reaching the point of decent endurance, and if you arent bothered by them being heavy (as is the case for grid and residential storage), they're fairly comparable to Li-Ion without the usage of relatively rare Lithium.
Yeah, negative prices finally incentivize storage technologies such as battery storage.
How does it incentivize it?
The problem with energy storage isn't a lack of incentives, it's a lack of solutions. There are currently no proven, grid scale, economical, and robust energy storage solutions.
There are lots of storage solutions that work within limited geographical areas (ie. Pumped hydro). But past that it's a crap shoot.
Batteries are absolutely nowhere near the capacity or longevity needed for grid scale storage.
The largest battery storage system in the world is primarily used for grid leveling and emergency power. And would be depleted in minutes under its maximum load.
It is also an incentive to shift demand when there is plenty of renewable power: charge your car , do the laundry and so on
Looks like it is possible to do in California already today, for hours, not minutes: https://reneweconomy.com.au/deeper-longer-cleaner-big-batteries-extend-domination-of-californias-evening-demand-peaks/
The battery solutions on grid scale are available now. They need to be built and paid for. Negative prices might help motivate investors.
TIL, thanks for the link!
That's pretty awesome ngl :p
The bigger the incentive the more money gets spent on funding the necessary R&D.
If you can actually get them. According to the article, it appears that an end user with his own battery system cannot actually get paid to store energy.
