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.
- Blogsites are treated in the same manner as social media sites. Medium, Blogger, Substack, etc. are not valid news links regardless of who is posting them. Yes, legitimate news sites use Blogging platforms, they also use Twitter, Facebook, and YouTube and we don't allow those links either.
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 OCTOBER 19 2025
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.

Technology without energy is a sculpture.

Long term, 50 years, we are looking at a terminal decline in what humanity will be able to do as a species. Going from kites to Apollo 11 in 50 years, for example, will never, ever happen again. And it wasn't the guidance computer that got you to the Moon, it was 1000 tons of kerosene in a tube that did it.

You, like many, simply look at electrical power and think everything's solved.

We certainly can run our affairs on renewable (sun, wind, water, maybe geothermal, tidal) sources, but that society will look nothing at all like ours. Think wooden windmills, not skyscrapers.

Probably for the best too, but the assumptions built-in to the necessary changes simply mean endless strife and pain in the meantime.

What do you mean I can't have a car? What do you mean I can only travel on a jet 4 times in my entire lifetime? What do you mean we have far fewer citrus fruits in the grocery store in winter? Doesn't food, like, grow all the time, like in the dirt? What do you mean we need fossil fertilizers and synthetic pesticides and endless machinery and irrigation to get me my smokehouse almonds? What do you mean I have to repair and keep my 10 year old washing machine for 20 more years? What do you mean I have to wear the same clothes? What do you mean I have to live in a box when my parents had a home with a front and backyard?

It's going to get ugly, and the fact that the richest few, and I don't mean Elon, I mean you and me chatting on a workday afternoon, have shiny toys means all that much.

Electricity runs the appliances that fossil fuels allow us to build.

Electrical power + water = rocket fuel. You don't have to use kerosene to launch to space - not that it's the highest priority anyway.

Why do you equate renewables with primitivism? What exactly stops you from building a skyscraper in a renewable-powered world? We do have green steel, concrete and glass. Besides, most use cases do not require skyscrapers in the first place, and they are seen as undesirable by many urbanists.

Now, yes, switching to sustainable lifestyles is not without compromise here and there, especially on the first stages of green transition. We have to put our effort into this, and there's no way around this. But with rational organizing, we can end up making something so much better!

Properly developed public transportation minimizes time and comfort losses associated with this mode of commuting, while making streets and air cleaner, freeing up plenty of space for pedestrians and buildings.
Comfortable high-speed rail minimizes the need for planes, enabling high-speed travel without all the airport controls and inconveniences and with plenty of amazing vistas.
Locally sourced seasonal varieties bring back the sense of excitement and allow you to explore so much more than just apples and oranges - there's a trove of underdeveloped cultivars waiting for their time to shine!
Plenty of said cultivars are not particularly demanding; also, green fertilizers (for example, microbiological ones, alongside good old manure and compost) are available and can be produced at any scale you need without the need for fossils.
Easily repairable (user-repairable wherever possible) tech removes financial and organizational anxieties about breaking your devices. Something broke? Just...take spare parts and an hour, and it's good as new.
Clothing can always be torn and reassembled in new creative ways! This opens up endless possibilities for creativity, and if you personally don't like it, I'm pretty sure a local atelier will be happy to help you.
Community is key to urban living! With more interaction between you and your neighbors and the culture of common responsibility over shared resources, you can turn any "box" into a sprawling place people love to live in. We need to combat the individualist culture to make it work, though.

In this age of sustainability, there's no issue in having a smartphone, or laptop, or whatever you write this on. In fact, right now there are tech brands oriented at sustainability, long-term support, user repairability and more. Fairphone, Framework, you name it!

We can build our tools, appliances and toys in a post-fossil fuel world. And we can make use of the materials we've already extracted to make it even greener.
