With climate change looming, it seems so completely backwards to go back to using it again.
Is it coal miners pushing to keep their jobs? Fear of nuclear power? Is purely politically motivated, or are there genuinely people who believe coal is clean?
Edit, I will admit I was ignorant to the usage of coal nowadays.
Now I’m more depressed than when I posted this
In my country, because of a decades long fearmongering and disinfomation campaing that destoyed the nuclear energy industry. So now we’re stucked with coal to keep the power running at night and during winter.
Let’s be honest though, rivers running low in summer so plants had to shut down, core material being bought from Russia and overwhelming costs for dismantling old plants together with no solution at all for final storage also did their part in it.
But we could have worked on these issues for years by now. Abandoning the entire industry also lead to slowdown in research and inovation in the field. Of course now we’re hopelessly behind.
Oor the ressources could be better spent in renewables, which are available as long as the sun exists, while nuclear will run out of fuel within the 22cnd century.
Also with nuclear Europe is entirely dependent on imports, primarily from Russia and russia-aligned countries. Being pro nuclear in Europe means being pro Putin.
Oor we can do both so that in the middle of winter when there’s only 6 hrs of sun (less when cloudy) we can still have electricity without ridiculously sized batteries.
Also uranium is so energy dense it can be mined and refined in Canada or Australia and shipped so, so very easily.
Nuclear won’t run out of fuel. But if renewable are so good, why are so many countries mining coal?
False information. There is enough fissionable material to last humans 10s of thousands of years.
Australia and Canada both have very large amounts of nuclear fuel that are currently unused because of short-sighted comments like this.
Uranium city is coming back baby!
And the feddit.de misinformation brigade has arrived.
I am quite sure i know a thing or two about politics that happened during my lifetime and i actively followed. Also i used to be a proponent for nuclear power when i was younger. But unlike the nuclear shills i am willing to accept when a technology is inferior and risky.
Funny, so do I.
Anyway, believe that “being pro nuclear in Europe means being pro Putin” or what ever absurd things you come up with.
I was here to give my response to OPs question. Discussing energy politics with the average German is as pointless as discussing biology with an anti-vaxxer and I have no interest in it.
Which is why you immediate derail the conversation by making ad himinen attacks, instead of interacting with the arguments… No suprise you cannot discuss things, because you don’t want a discussion in the first place.
It’s been discussed to death, check the most recent thread about Scholz’s comment on !worldnews@lemmy.ml if you want to read through all of the discussion AGAIN.
But you are right. I’m not willing to have a discussion about it with you. Just like I wouldn’t want to have a discussion about astronomy with a flat earther.
Your “nuclear = support russia” comment made it very clear where you stand on the issue and on what basis. So discussion is entirly pointless.
But it wasn’t really meant as a personal attack against you, if that comforts you. It’s a systematic problem, just like my other comparisons.
Why are you pro-coal?
i am pro renewables. It is the pro nuclear faction that tends to be pro coal too, just that they pretend they aren’t. But it is the same businesses, the same industries and the same lobbying against renewables that unit pro coal and pro nuclear.
If you are anti-nuclear you are pro-fossil fuels. 100% renewables is a pipedream that is pushed by the energy companies amongst sports ads with scenic pictures of windmills in the background, while you ignore the other 44% of energy generation.
Well, nuclear energy is expensive anyways and the amount of uranium on this world seems quite limited.
It’s just not the technology of the future. In the long term we should use regenerative energies that are way cheaper.
Right, but that’s why people are talking about nuclear as a bridge technology, not as a permanent solution. Whether or not we can make it pencil out before smashing through all of the critical tipping points in global temperature averages is not something I’m qualified to have an opinion on, but I’m credibly informed that we might at least want to give it a serious look.
At one point in the future I’m sure we can look back, do the calculations and see if that had been a good bridge or an expensive thing for the taxpayer to deal with the dismantling and long time storage.
As of now I think the time of that bridge technology has come to an end anyways. We now have efficient renewable energies available. And concepts for energy storage. I think we should invest in that instead of putting the money into a thing of the past.
Nuclear is no more expensive than renewable. The amount of uranium is limited, but it’s not the only fuel for nuclear.
Sure it is. The World nuclear status report 2021 for example says it’s five times more expensive than wind energy.
And sure there are other fuels for nuclear. But I think most of them are even more limited?!
The paper doesn’t account account for availability. Nuclear has over 90% availability, which means for 1MW of power installed, you get on average over 0.9MW of power to use. Renewable are far below that, between 40 and 60% iirc. Which means you need to double the cost for a defined output. And that doesn’t consider batteries.
Unless the document talks about that, please point me to the right chapter then.
Damn. I shouldn’t have linked auch a long PDF. What are you talking about? I’m referring to the diagram (and text) on page 293. The annual Levelized Cost Of Energy.
It’s not only calculated on sunny days. They take the annual energy output for the calculation. Availability and everything included or these numbers wouldn’t make any sense.
And yes, we need batteries. But the nuclear plants also need other (faster) plants alongside. And this match isn’t a close call. With a 5 fold increase in being economical, we have plenty of money to spare to afford some batteries and hydroelectric dams.
I was looking at the building cost. Looking more into the Wikipedia article, it seems to account for availability. But the numbers are very speculative still, there is a crazy variation both for the specific data points and for the studies. Another big factor is the interest rate for investment which can double the cost of nuclear energy depending on the assumption.
Another thing that bother me is the speculative nature of these things. No photovoltaic power plant ever went through its whole lifespan. No significant energy production was made with variable renewable. Whereas nuclear was used for 70 years now. Yet the speculation makes it like nuclear will be expensive and unreliable and renewable will be cheap and reliable when the actual history is the exact opposite. Technology advances obviously, but still. I don’t consider renewable to be a tried and tested technology that scales while nuclear is.
Idk. Solar cells have been around for a while, too. Wind turbines are kind of simple devices. I bet an engineer can predict their maintenance cost and lifespan fairly accurate. Hydroelectric power plants have been around for more than 100 years. Electric cars have been invented before the combustion engine took off. Nuclear power has been around for some time. But you can’t use that as an argument and simultaneously argue about using thorium which large scale deployments are still hypothetical.
And I don’t think those numbers are 500% off. You can double some cost and were only at 200%. And they’re not complete speculation. They took the actual numbers of the previous year. And the years before that. These numbers are the ‘actual history’.
Pardon? Norway? New Zealand? Switzerland? Iceland? Sweden? Countless others I probably forgot because I’m bad at geography? The USA and China, Philippines, Indonesia all have major ‘variable renewable’. Thousands and thousands of megawatts of energy are generated this way as of today. Then there is biomass if you’re geologically not that favored by nature, but I barely know anything about that. And who says we can’t use the sun and wind? Of course we can also use those.
What proportion of those countries’ energy is renewable? Because that’s the big problem: when renewable are less than 50% of your energy, you can balance the load with the rest ; when it’s 80%, it’s a whole different story. No country has the most of its energy from renewables, and thus we don’t know if it can even work over time, it’s not proven. The scale matters. Producing a prototype is not the same as the whole industrial thing. That’s exactly what’s happening with nuclear btw: after 30 years of abandon, the construction is hard and more expensive and time-consuming than expected because we need to relearn how to do it. But prototype is not industrialisation. And that’s a problem renewable will run into: industrialisation. Where do you all the silicium you need for the batteries and solar panels? How do you deal with balancing the load? And there will be unexpected problems. Nuclear already dealt with these problems. Will renewable actually be able to expand everywhere? Because there isn’t wind and sun everywhere. I severely doubt Switzerland can power itself this way for example.
And then, isthere any solar or wind farm of more than 30 years? I’m pretty sure there isn’t because their lifespan is less than that and the last models that are so efficient are less than 10 years old anyway.
The experience also shows that all countries that went for renewables ended up using more fossile energy btw. Spain and Germany most notably. How do you answer this problem? This is not theory, this is what happened when countries decided to use renewable energy.
Thorium is one of the most abundant material on earth. Unlike lithium for example.
Yeah. But the technology is - at this point - more sci-fi than anything else. Probably nothing we need to worry about in the next few years.
And you still need to mine some non-renewable resource. It’s still nuclear and produces waste. And it seems super expensive.
There are working thorium reactor for 50 years or something. Hardly sci-fy.
Renewables need batteries to work. Which needs lithium.
Sure. Just use molten salt energy storage, hydroelectric dams or whichever of the dozens of technologies makes most sense where you are.
Combine different kinds of renewables so you get power at night and when the wind isn’t blowing. Build more then enough and if you got excess energy, maybe make some hydrogen.
Have your devices and industry ‘smart’ so it draws less power when there’s less supply.
You really don’t need to do everything with ‘normal’ batteries like in a smartphone.
The ‘working’ thorium reactors are for research. They don’t generate energy. At least if we’re speaking about generating energy for a whole country. The planned thorium reactors of the next many years also don’t generate any significant amount of energy. With that argumentation we also (almost) have nuclear fusion power plants.
A thorium power plant that contributes to the power grid and shows up in the numbers is sci-fi. I mean, it’s not impossible. It’s just lots of very expensive work left to do.
Thorium reactor that contribute to the power grid is as much sci-fy as all the technologies you describe to have a working renewable energy grid.
Meanwhile there are whole countries powered from nuclear energy, and switching to thorium makes no difference for the grid itself.
Finally if ecofanatics didn’t shut down or sabotage research on thorium reactors we would be closer from a working tech.
