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.

Everything you said tracks except 5. Renewables are already cheaper than fossil fuels, and that's with the subsidies for fossil fuels.
From a purely economic perspective fossil fuels don't make sense anymore, they're being kept around because fossil fuel companies are using immense amounts of money to fight against renewables.
People seem to forget renewable energy is essentially free. Sure there's maintenance and upfront cost but that's true for all energy generation. Fossil fuels simply can't compete and it's only going to get worse as we get better at collecting renewable energy.
No.
We're going to be paying 2-3 times more because we need to create enormous amounts of extra energy to clean the atmosphere.
That, and renewable energy isn't free either. Solar panels require regular replacement as they (still) degrade quite a bit (too much) over time. If I'm not mistaken, they still require replacement every 10 or so years.
Windmills require regular maintenance. The power grid requires maintenance.
Wind and solar requires enormous batteries that degree and require regukar replacements.
Renewables are only so so renewable, don't expect to pay anything less for the same amount of energy. Then now we will have to generate these enormous amounts of extra energy to take the CO2 out, who is going to pay for that? We all are.
So yeah, do expect to pay 2-3 times more for energy when this all starts, ideally tomorrow but likely 20 years from now as we're still not done partying.
I already mentioned maintenance.
You people act like coal plants don't have teams of maintenance engineers onsite 24/7.
I'm not acting like anything. I am fully aware of the requirements of fossil fuels. I'm mentioning all the requirements for "renewables" because there people typically act as if there are zero costs (and pollution and maintenance) related with it.
I'm not pro fossil fuels, not at all. Don't get me wrong. I'm simply saying that were Ina SERIOUSLY fucked situation that simply won't be solved within our generation, if ever at all. We're at a cliff and a small group just keeps partying while shuffling closer and the rest of the world gleefully shuffles right after them. A few renewables are not going to fix this
Price doesn't matter if it's cloudy like most winters with barely any sun and the wind is not blowing. Solar also won't work at night and energy storage is crap, batteries are very much not renewable. Of course there is reversible hydro plants but these can't be used everywhere and are a disaster for local ecosystems.
Everyone is acting like renewables will fix everything.. They won't. The only thing that can replace fossil fuels right now is nuclear, which is also not renewable, but at least we have plenty of fuel for it.
if we were to replace current fossil plants with nuclear, the fuel runs out in 70-100. years and will get much more expensive. Think about paying ten times your electricity bill in 20 years.
It is possible to run a 100% renewable grid, using technology like hydrogen or other chemical storage system.
Solar wont have the output in winter. Nuclear plants will have to shut down in summer, because the water supply will get unstable. France nuclear heavy energy production could collapse within the next two decades if the current trend of lower river water continues. And there is no reason to believe otherwise.
But the biggest issue is that the grid is thought the wrong way around. Currently the supply is adjusted to the demand. But for many applications the demand can be adjusted to the supply. On the household level that means your fridge and washing machine to run, when there is a lot of energy available. On the industrial level that means to automate productions and adjust their intensity to available energy.
Not all nuclear plants are the same. Some can use nuclear waste as fuel. Others are small and modular which allows them be turned on and off as needed and also be deployed easier and cheaper. We need solutions sooner, rather than later. Nuclear tech is here now, storage for renewables still needs more time to refine and streamline.
nuclear plants take decades to project and build. And the modular and reusing waste plants are still in the concept stage
Modular reactors have been equiped to submarines for decades, they passed the concept stage long ago.
There are many kinds of nuclear reactors, but not much was invested into them to bring the cost down.
I am not saying that nuclear is perfect. Unless we figure out fusion it won't be a long term solution. It's just what we need right now to get rid of fossil fuels while we figure out the large scale renewable grids with good storage tech.
Hydrogen is a good option, if only EV manufacturers focused more on that... Charging the EV would be a matter of minutes not hours and there wouldn't be issues with colder climates like the current batteries have.
If nuclear is so easy now, why is nobody doing it?
@fatalError @tryptaminev
Hydrogen doesn't work and nuclear is too expensive CCS also doesn't work.
Renewables work and are cheap and easy to install. Combine them with battery in a SunWindBattery system and maybe a bit of hydro and we have enough energy.
There are so many solutions.
But instead we are using gas and burning oil. Politicians and fossil fuel companies obstruct renewables and other climate mitigation
Because profit is more important than human survival.
Thermal hydro has pretty much solved the storage problem and solar works fine during the winter.
There are many solutions to storage, not many being used. If someone is talking about storage, in 90% of cases they mean batteries and until that changes the problem isn't solved.
As for solar during winter, it might work, barely, but at much lower output just because you have a lot less sunlight during a day. So you have to cover 16-17 hours of no light with just 7-8 hours of sun. This varies wildly depending on location of course.
