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.

Although I agree with this comment, this is exactly what the covidiots said. "Just google it". If you want us to believe your controversial opinion, you're going to want to take the time to add the most credible sources you can find to back you up.

...Nuclear power is a huge waste of money....

...this is the scientific consensus on the issue.

A battery of tests were performed on the economics of mitigating the impending climate disater. These tests indicated that nuclear is a huge waste of money (p<0.05) (Blake, 2023)

Hahaha :)

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!! :)”

And the argument vanishes into thin air...

How do we deal with balancing the uneven load renewables produce in places where pumped hydro isn't an option for power storage? I.e. lowland areas. Here in the southeastern US, night almost always means no wind as well as the obvious no sun. Chemical batteries, afaik, aren't a sustainable solution ATM.

[–] [email protected] 0 points 10 months ago (1 children)

Thanks for the question. Firstly, most places have a power grid which is far larger than their locality. For example, the southeastern United States is connected to a single big grid which connects every smaller sub-grid east of the Rocky Mountains. This means that a home in Florida can be powered all the way from the Bath County pumped-storage facility in Virginia, the second largest such facility in the US.

Hydroelectricity can also be generated by rivers, which are commonly used in lowland areas, and geothermal is also viable at any time of the day. Biomass is also an option, though it’s the last resort really, although as long as it’s responsibly managed, it can be nearly carbon neutral.

There are also alternatives to pumped storage, lots of them. Compressed air, thermal storage, and hydrogen are a few examples just off the top of my head, though I’m sure there are many more. Pumped storage is just very efficient and cheap, so if we can plausibly do it, it should be the first choice. And if it can’t be done somewhere, then we should connect that place to somewhere which can!

Hydroelectricity

Destroys aquaculture. TVA has absolutely killed those rivers, and there is no way to sugar coat that.

Geothermal can't be used in most places (but should absolutely be used where it can be)

Biomass is just burning shit all over again (thought that was the point of not burning coal).

I'm also skeptical of the pivot from using renewables as a decentralized solution and then touting a massive grid which requires lots of infrastructure. Unless your problem with centralization is targetability by bombing.

I've not heard much about compressed air as an energy storage medium, or thermal storage besides from using solar arrays to reflect light and melt a metal core (like Gemasolar which is another centralized solution), but I've heard nothing good about hydrogen except from breathless techbro types.

Meanwhile Nuclear is a mature technology now, absolutely a less dangerous solution than coal (even without looking a climate change knock-on effects, just looking at the effects coal dust has on populations near coal-fired plants), and can be used to meet the base-load of a local grid with various renewable solutions used to meet peak load demands.

I hate when people say “stop importing it from Reddit” like half of us didn’t migrate from there.

What the fuck did you expect to happen? Reddit didn’t believe that. The users that participated in the site did.

[–] [email protected] 1 points 10 months ago

Also worth noting are the centralization and security risk aspects of nuclear

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.

[–] [email protected] 1 points 10 months ago (1 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.

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.

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.

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).

I wrote a larger comment addressing this, but honestly, you’d be better just googling it. It’s eminently plausible, it’s the industry consensus. Here’s a Wikipedia link for you: https://en.m.wikipedia.org/wiki/100%25_renewable_energy

Some argue that transitioning to 100% renewable energy would be too slow to limit climate change, and that closing down nuclear power stations is a mistake.[122][123]

"Nuclear power must be well regulated, not ditched". The Economist. 6 March 2021. ISSN 0013-0613. Retrieved 31 January 2022. McDonnell, Tim (3 January 2022).

"Germany's exit from nuclear energy will make its power dirtier and more expensive". Quartz. Retrieved 31 January 2022.

In November 2014 the Intergovernmental Panel on Climate Change came out with their fifth report, saying that in the absence of any one technology (such as bioenergy, carbon dioxide capture and storage, nuclear, wind and solar), climate change mitigation costs can increase substantially depending on which technology is absent.

Thanks for your sources which support my claims.

Some argue that transitioning to 100% renewable energy would be too slow to limit climate change, and that closing down nuclear power stations is a mistake.

So, what we have here, is two opinion pieces from business-focused news websites, vs the scientific consensus of domain experts in the field of energy production, the IEC, IEEE and countless others. Very cool, very good proof of your claims.

Germany’s exit from nuclear energy will make its power dirtier and more expensive

“Germany has committed to source 80% of its electricity from renewables by 2030”

This article contains no arguments whatsoever that nuclear is better than renewables.

Nuclear power must be well regulated, not ditched

“Nuclear power has a lot of drawbacks. Its large, slowly built plants are expensive both in absolute terms and in terms of the electricity they produce. Its very small but real risk of catastrophic failure requires a high level of regulation, and it has a disturbing history of regulatory capture, amply demonstrated in Japan. It produces extremely long-lived and toxic waste. And it is associated with the proliferation of nuclear weapons. Most of the countries outside Europe that use nuclear power have some history of attempting to develop a bomb. All these factors contribute to an unease with the technology felt, to greater or lesser extent, by people all around the world.”

This isn’t even all of the drawbacks. The advantages of nuclear power, according to that article? It’s safe (but still not as safe as renewables”, and “hey, at least it’s better than fossil fuels”. That’s not the argument. The argument has to be how nuclear is better than renewables.

We’re done here.

If you are worried about the cost of nuclear energy, you don't give a shit about the environment.
