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.
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.

Those photos don’t seem great for the environment.
There's actually research that shows that farming under solar cover increases moisture retention and the crop yields of certain plants. You'll also note that a lot of these installations are on marginal land- steep hillsides, arid land, and even floating on reservoirs. The latter slows the rate of evaporation from the reservoir as well, so it has a net environmental benefit.
You're right though, not every installation is perfect. But we seldom ask these same questions when it's a new housing development or a Walmart with a moat of paved parking around it.
The impact of our incessant growth continuously erodes the environment, wiping out ecosystems for development and depleting our finite materials. Our growth mindset excuses ourselves of the "lesser evil" of renewable energy.
Indeed this isn't great for the environment and I'm again disappointed about this community's shortsightedness in refusing to see it that way.
This message was sponsored by big oil.
Nothing people do has zero impact. But pretty much everything else has a bigger one. Coal will utterly destroy the land, and the gases emitted after it burns will destroy far more.
Solar like this on a few percent of the land will supply all the electricity people need. So it looks huge, but is surprisingly low-impact compared with other options, or things like raising cattle
So... I considered trying to start an energy-sustainable data center...
The math doesn't check out. One square meter of earth gets about 1,000 watts from sunlight. Our current solar panels only run at 20% efficiency at best. Servers I looked at average 500 watts... and we usually put a bunch of servers stacked up in a single rack, which you can only fit one of in one square meter.
As AI grows, it's only gonna get worse. We need nuclear or geothermal or hell, fusion if we can make it not 50 years away.
But it explains why Amazon and such are looking into smaller scale nuclear. Let's see how that goes I guess...
Edit: I'm not saying solar is a bad idea. We just need more energy production of many sorts
The thing is we can gather that solar energy from other locations too. We can harvest wind and hydro, which are just solar power in a different form. We can gather solar energy that's deposited off of our site in this way.
You're assuming that the world is covered in server racks. I don't expect anything like that, even with significant increases in datacenter construction.
Let's assume 1kw per person. 10 billion people at peak population some time hence. So about 150 billion m^2^ to provide 1kw per person 24/7. The earth's surface area is 510.1 trillion m², of which about 1/3 is land. So we're probably just fine on renewables.
Your numbers are old. If you are building today with anyone ad much as mentioning AI, you might as well consider 100kW/rack as ”normal”. An off-the-shelf CPU today runs at 500W, and you usually have two of them per server, along with memory, storage and networking. With old school 1U pizza boxes, that’s basically 100kW/rack. If you start adding GPUs, just double or quadruple power density right off the bat. Of course, assume everything is direct liquid cooled.
I guess the lesser of two evils is better than doing nothing.
Maybe one day fusion will finally deliver and we might have cheap and clean energy with no consequences to the environment other than a few big reactors in a country. But until that day arrives and we work that out we have to transfer and Wind, Solar and batteries are winning because they are cheaper than gas, coal and nuclear.
Just casually advocating for mass murder. Great post, dude, I'm sure that you are a nice fellow to have around here. Not.
Tired of you people bitching about how the only large scale non-nuclear solution to our problem isn't "great for the environment" when it's the ONE thing that isn't actually destroying the planet. Can't have anything less than 100% magical perfection, nobody will ever please you.
I never said don’t do it, but covering miles of land with solar panels is obviously going to destroy that environment. I’m tired of people like you who can’t stop reading novels from sentences. Go reee to someone else.
Destroy it compared to what
Tbh it’s better than strip mining or coal power plants.
And in extremely hot areas, planting crops under solar arrays is a great idea, and can help more sensitive crops survive in areas where they’d otherwise get baked to death.
