Don’t import Reddit’s extremely ignorant takes on nuclear power here, please. Nuclear power is a huge waste of money.

If you’re about to angrily downvote me (or you already did), or write an angry reply, please read the rest of my comment before you do. This is not my individual opinion, this is the scientific consensus on the issue.

When it comes to generating electricity, nuclear is hugely more expensive than renewables. Every 1000Wh of nuclear power could be 2000-3000 Wh solar or wind.

If you’re about to lecture about “it’s not possible to have all power from renewable sources”, save your keystrokes - the majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable. Again, this isn’t my opinion, you can look it up and find a dozen sources to back up what I am writing here.

This is all with current, modern day technology, not with some far-off dream of thorium fusion breeding or whatever other potential future tech someone will probably comment about without reading this paragraph.

Again, compared to nuclear, renewables are:

  • Cheaper
  • Lower emissions
  • Faster to provision
  • Less environmentally damaging
  • Not reliant on continuous consumption of fuel
  • Decentralised
  • Much, much safer
  • Much easier to maintain
  • More reliable
  • Much more responsive to changes in energy demands

Nuclear power has promise as a future technology. It is 100% worth researching for future breakthroughs. But at present it is a massive waste of money, resources, effort and political capital.

Nuclear energy should be funded only to conduct new research into potential future improvements and to construct experimental power stations. Any money that would be spent on nuclear power should be spent on renewables instead.

Wow I'm surprised to see people are actually downvoting you and arguing about this. It's common knowledge that the cost, impact, and build-time of new nuclear plants makes them a poor choice for energy. Not only is wind/ solar cheaper, it's faster to build.

[–] Blake@feddit.uk 37 points 2 years ago

Redditors are unbelievably brainwashed in this topic, and a lot of Redditors moved over to Lemmy. I have dragged this metaphor to water countless times before, and when I suggest that they could consider drinking, they just arrogantly declare that I don't understand the facts around liquids, that I don't have any basis for my claims that they should drink it, and that by arguing that people should drink more water, I somehow supporting Coca-Cola.

[–] regul@lemm.ee 12 points 2 years ago (2 children)

It's also common knowledge that the more often you build something, the lower its price tends to go as that knowledge spreads. It's part of the reason it's so expensive to build trains in the US and so cheap in South Korea and Spain.

[–] burningmatches@feddit.uk 32 points 2 years ago

This famously isn’t true for nuclear power. It just keeps getting more expensive.

The French nuclear case illustrates the perils of the assumption of robust learning effects resulting in lowered costs over time in the scale-up of large-scale, complex new energy supply technologies. The uncertainties in anticipated learning effects of new technologies might be much larger that often assumed, including also cases of “negative learning” in which specific costs increase rather than decrease with accumulated experience.

https://www.sciencedirect.com/science/article/abs/pii/S0301421510003526

And this research was done before Fukushima, which increased costs even further.

[–] Blake@feddit.uk 26 points 2 years ago (2 children)

This is just more reasons to prioritise the already cheaper renewables, isn't it?

You can have this copy/paste from like 5 minutes of googling. You can also run your own study yourself by just googling "average kwh price nuclear" and "average kwh price wind" and see how it looks. You can also google "average co2 eq emissions total lifetime nuclear" and likewise for wind/solar PV. This is extremely simple stuff, guys. I am basically saying, "lentils are cheaper than steak" and you're asking for citations.

Wow look isn't it crazy how nuclear is the most expensive one?

Mycle Schneider, author of the World Nuclear Industry Status Report: "Nuclear power plants are about four times as expensive as wind or solar, and take five times as long to build. When you factor it all in, you're looking at 15-to-20 years of lead time for a new nuclear plant."

Differences in carbon emissions reduction between countries pursuing renewable electricity versus nuclear power, published in nature energy: "We find that larger-scale national nuclear attachments do not tend to associate with significantly lower carbon emissions while renewables do. "

[–] Ertebolle@kbin.social 18 points 2 years ago (3 children)

This chart is from the "Fraunhofer Institute for Solar Energy Systems," I wonder whether they might be a wee bit biased. It also puts the "consequential cost to health, environment and climate" of nuclear as higher than coal, which is bananas, and their data on lifecycle carbon emissions from nuclear comes from a noted anti-nuclear group (and the article even admits as much).

"When you factor it all in, you’re looking at 15-to-20 years of lead time for a new nuclear plant." Cool, let's start building a whole bunch of them right now and then worst-case in 20 years we'll have too much electricity.

"In the next 10 years, nuclear power won't be able to make a significant contribution" I appreciate your optimism but we are deeeeeefinitely not going to come anywhere close to phasing out fossil fuels in power generation in 10 years; we're not even going to be done with fossil fuels on days that are particularly sunny in the solar cell areas and particularly windy in the wind power areas.

[–] denial 21 points 2 years ago

The Fraunhofer ISE is a reaseach institut with a focus on solar. It is very well respected and I would be very suprised if they where biased here.

[–] Blake@feddit.uk 18 points 2 years ago (1 children)

Why would we waste money on nuclear when we could build renewables instead? It makes NO sense. Renewables are cheaper and cleaner.

[–] Ertebolle@kbin.social 11 points 2 years ago (1 children)

Well now you're back to arguing about new construction instead of keeping existing plants running.

Also, we can build both. Surely you appreciate that there are other factors slowing the speed of the energy transition besides the availability of capital, and that while nuclear has its own roadblocks, many of them are different from + don't overlap or compete with those standing in the way of renewables.

[–] Blake@feddit.uk 9 points 2 years ago (1 children)

Capital (money) and capital (political) are the only roadblocks between us and a 100% renewable future. So no, there's no value to wasting either of those on nuclear when they could be more wisely proportioned to renewables. Pretty much the only resource that nuclear consumes that isn't consumed by most renewables would be uranium. I'm willing to just go ahead and say we can leave that one in the ground.

[–] Ertebolle@kbin.social 9 points 2 years ago (1 children)

They’re really not, and if you think that then you need to read more. And “political capital” isn’t some big fungible pool of quatloos, it’s a lot of little tiny stupid slow fights.

[–] Blake@feddit.uk 10 points 2 years ago (1 children)

Okay, go ahead and list the resources used for building nuclear reactors that isn't used for building other renewables.

Not my optimism, that's a quote from an industry expert, actually. But sure, whatever you say.

[–] Iceblade02@lemdit.com 8 points 2 years ago* (last edited 2 years ago)

and this is a short intro to why a (60%/40%) split between renewables and nuclear may be the most accessible fossil free solution, and why the value of adding more variable renewables to a grid falls sharply the closer you get to 100%.

Also, the last article you posted is paywalled.

Thorium reactors were made those in the 60s, they weren't pursued because thorium can't make nuclear bombs.

I’m on my phone, dude, I’m not gonna juggle a dozen sources on this tiny screen and crappy keyboard just to prove you wrong, you’re more than capable of using Google to find the facts yourself. I challenge you to prove me wrong. You can even cite some hilariously biased source like World Forum of Nuclear Investor Funds or something, those ones are always fun because they’re like “oh with our super cool advanced new nuclear reactor that doesn’t exist, it’s as good as solar or wind for almost 150% of the cost!! :)”

I mean IDK if Rueters meets your rigorous standards for journalistic excellence (or why you can't just google something so simple) but here you go new nuclear is more expensive and and worse for the environment than renewables.

[–] Maldreamer@lemmy.ml 10 points 2 years ago* (last edited 2 years ago) (9 children)

I agree with you on nuclear being more expensive as all facts point that way and future nuclear technology, but i dont understand how we could transition to a 100% renewable energy sector, It would be good if you could give a citation or explanation for that. Diverse and distributed source is how we get an energy secure grid, renewables could help with the distributed source part, but when it comes to diversity the popular renewable technologies wind and solar are very limited, both of these source cant power a base load without batteries (this applies mostly to solar, but wind too has low output at night). Also there is this issue witj managing generation and demand (Nuclear too have issue with this as its not possible to quickly adjust nuclear power generation like other conventional spurce). A full renewable energy grid would depend on batteries, currently we have much limitation with batteries. Mature technologists of acid based batteries require huge areas, and lithium based ones would require rare lithium which its mining alone would cause alot of pollution, and relying on other alt battery technology itself would be a long stretch as its development and commercialisation to usable form would take years to achieve as the same case afforable future nuclear technology.

Other alt renewable energy like geothermal could help with base load (not sure, someone could correct me if this is not the case), but itsnt possible everywhere. The same goes for tidal plant as it depends on geography and specific time of day. With this scenarios if we were to move to a 100% renewable grid then, the price for energy will increase at night time in a way that i think could reach nuclear energy rate.

A 100% renewable grid would need a lot of batteries and that too could drive the price up and possibly contribute to climate change. Also solar panel manufacturing is a very intense process with a lot of carbon impact, i read this on a text during my academics (havent checked the source for this other than that).

[–] Ooops@kbin.social 7 points 2 years ago* (last edited 2 years ago) (1 children)

Also solar panel manufacturing is a very intense process with a lot of carbon impact

The carbon impact mostly is energy used in production. So it's high when you produce solar panels powered by shitty coal plants and basically non-existent when you have build them once and are constructing replacements with solar energy. (The same is true for nuclear btw and also often completely misrepresented in discussion. Nuclear plants in a country full of nuclear plants have a much lower carbon footprint. That's not some technological or scaling effect as often claimed but the simple fact of building the reactor and enriching the fuel with energy already green)

A 100% renewable grid would need a lot of batteries and that too could drive the price up

Actually no. The grid would need batteries (but also alternatives like capacitors or fly-wheels) for short-term stabilisation, but the amount is limited. The grid also need long-term storage but here batteries are completely inadequate. Also the requirements for batteries are usually misrepresented. No, we don't neen some bullshit Lithium-ion batteries or similar stuff requiring rare earths and other rare ressources. Those are used in handhelds where energy density is the main concern. I can perfectly build a stationary grid battery cheaply and without rare ressources as nobody cares if that building-sized installation is 5% bigger and 30% heavier than a build with lithium-ion batteries and also gets 20° hotter in operation... because it's not a handheld.

Case in point: One of the very first things that happened in Germany the moment the new government was sworn in and long before they could actually do anything: energy companies started installing the first battery-based storage units as they now were no longer intentionally sabotaged in creating storage infrastructure for renewables. What did they use? Car battereis. Used ones that were already deposed. Dirt cheap for costs barely above the recycling value. Because the requirements in grid stabilisation and short-term storage are indeed completely different that in cars (again: energy densitiy vs. low price and car batteries with only 60% of their capacity left were completely okay for that job).

Germany literally just shut down their existing nuclear plants and replaced them with fossil fuels.

So even if what you're saying were true (and I'd happily sit here and punch holes in it if I thought you were actually open to an argument - anti-nuclear people somehow seem to think that you can build all the solar/wind farms and transmission lines you want without running into the same endless messy regulatory battles you get with nuclear), none of it would be relevant here because the plants were already built and already working and responsible for like 1/8 of Germany's electrical production - it wasn't a cost decision, it was a bullshit anti-nuclear one.

Also: the graph at the top shows the growth in Germany's installed wind capacity in Germany leveling off - do you think that's happening because they just don't feel like building any more wind power, or is it possible they're running into some limits on how much they can generate efficiently that way?

[–] Blake@feddit.uk 26 points 2 years ago

This claim is patently false.

[–] Rayleigh@feddit.de 16 points 2 years ago

That's completely false.

responsible for like 1/8 of Germany's electrical production

More like 2-3%

it wasn't a cost decision

Not exclusively, but the high price of nuclear is one of the main points in the decision

the graph at the top shows the growth in Germany's installed wind capacity in Germany leveling off

Because the graph stops in 2022. The growth now is accelerating and even more so for solar power which OP conveniently does not show us

Given this thread is about new nuclear, I'm not sure why you are making up beliefs about what someone else in the thread believes. Personally a fan of old nuclear plants since their biggest expense (financial and likely ecological) is making them, so keeping them running is good as long as we are relying on fossil fuels.

is it possible they're running into some limits on how much they can generate efficiently that way?

Why just speculate on it while insinuation someone is wrong about something when you could look it up? From what I can gather, it looks like administration/licensing delays, court cases, and rules limiting how close they can be to residential buildings (apparently 10 times the height of the turbine) are the main contributors to the slowdown.

Also, solar is still growing more quickly and 2023 is having quicker growth in wind than last year (which was itself an increase from the previous year), so the trend being shown may already be outdated. Granted, inflation apparently are an issue now (not when the slowdown happened, but now as the rate of wind installation is increasing). And the rate of increase isn't enough imo, but building new nuclear instead of using the same resources to build solar or wind at this point means relying more on fossil fuels.

If you had just said this and stopped writing then you'd have saved yourself time and embarrassment. I can dunk anytime, anywhere on whatever arguments you dream up, because definitionally if you're arguing with me about this then you have no idea what you're talking about. It's a fool-in-a-barrel type of situation, really.

Anyways, enough merry-making, to the meat of your comment:

Germany literally just shut down their existing nuclear plants... it wasn’t a cost decision, it was a bullshit anti-nuclear one

Nuclear power has huge cost implications, economically and politically, which make it less viable. If Germany had built renewables instead of nuclear, would they have turned off the renewables that were producing the cheapest, cleanest energy ever known, with zero fuel costs and minimal maintenance costs? You make my argument for me.

The decommissioning of the german nuclear power plants was planned in 2011 because nuclear is a waste of resources. German scientists know this as well as I do. You're the one arguing with them.

"Nuclear energy is also often more expensive than wind and solar power, there are no longer any real advantages with nuclear energy.” - Volker Quaschning, a professor of renewable energy at the Hochschule für Technik und Wirtschaft Berlin. “Nuclear power plants are a hindrance to the energy transition. They are not able to run in stop-and-go mode and cannot really compensate for power fluctuations that arise when using solar and wind energy. With Germany looking to expand solar and wind power very rapidly over the next few years, now is a good time to shut down nuclear reactors to make way for renewable energy,” he said.

“In the German context, the phase-out of nuclear energy is good for the climate in the long term. It provides investment certainty for renewable energy; renewables will be much faster, cheaper and safer than expansion of nuclear energy,” - Niklas Höhne, a professor the mitigation of greenhouse gases at Wageningen University in the Netherlands.

...and replaced them with fossil fuels

I think you're referring to the emergency recommissioning of German coal power plants in response to Russian gas being held hostage over the Ukraine war? It's not like they went "meh fuck the climate lol lets just turn off nuclear and put on the old coal burner for old time's sake".
