Chasing profit is how we got here. This shouldn't be the basis of the decision. If it's the only thing we can use to drag conservatives along though, I guess it'll have to do.

It's not about chasing profit though, it's about getting to net zero as quickly as possible using finite resources. Any money that goes to nuclear could be going to renewables, which would get us there more quickly.

[–] echo64 46 points 1 year ago (14 children)

This article is about profitability, not cost to net zero. They are very different things. It also ignores the cost of scale, go all in on say solar today and that doesn't make more panels available, the increased demand would raise prices and suddenly its not so profitable.

Nothing is as simple and easy as people want it to be.

However, the researchers show that in terms of cost and speed, renewable energy sources have already beaten nuclear and that each investment in new nuclear plants delays decarbonization compared to investments in renewable energies. “In a decarbonizing world, delays increase CO2 emissions,” the researchers pointed out.

They talk about profit to get the attention of money people, but the ultimate goal is decarbonization. Hell, the title of the source article is "Why investing in new nuclear plants is bad for the climate".

Yeah no shit. We already knew nuclear was not profitable, but it’s clean & makes tons of power, so it’s a good deal for everyone that isn’t a business & wants cheap & clean energy.

The question has always been what does one do when the renewables aren't providing enough power (ex: nights, etc). The current solution is natural gas. It would be a big improvement if we would use a carbon-free source like nuclear instead.

Pumped-storage hydroelectricity is an old and proven method for load balancing intermittent power sources. Would like to see more of that as geography permits.

[–] complacent_jerboa 41 points 1 year ago (3 children)

The "as geography permits" part is a big obstacle, unfortunately.

[–] [email protected] 8 points 1 year ago (3 children)

Actually it isn't if you stop only looking at places that are also suitable as power plant, that is, have a big river flowing through them.

You can do pumped hydro in an old mineshaft.

According to the article, the researchers concluded that nuclear reactors are not a good fit for that role.

[–] [email protected] 13 points 1 year ago (3 children)

The growing idea is to just have a shit load of renewables, everywhere. The wind is always blowing somewhere, and the sun shines through the clouds. If you have a ridiculous excess total capacity then even when you're running at limited capacity you could still cover the demand. Basically, most of our renewable infrastructure would actually be curtailed or offline a lot of the time.

Here's an example of what can be done with 5 hours of storage. 5 hours is a 25% participation rate of V2G where the participants offer a third of their battery capacity.

https://reneweconomy.com.au/a-near-100pct-renewable-grid-for-australia-is-feasible-and-affordable-with-just-a-few-hours-of-storage/

If going with the (false) assumption that nuclear can hit 100% grid penetration, it would take decades to offset the carbon released by causing a single year of delay.

The lowest carbon "let's pretend storage is impossible and go with 100% nuclear" would still start with exclusively funding VRE.

Profitability is so much not the point here and also, there's no reason for different energy production sources (especially ones that are base power vs incidental power) to be in conflict. Do both of them.

K, but this isn't about profits. This is about not destroying the environment, which nuclear can help with (you know if nobody bombs the plant)

[–] [email protected] 12 points 1 year ago (18 children)

But it's also about cost. Nuclear is far more expensive upfront, more expensive to maintain, and more expensive to decommission. Cheap, agile renewables will be an easier option for the vast majority of the planet

Everything is about profits. Otherwise we wouldn't even be in this mess.

That's not difficult. Nuclear is extremely expensive.

With renewables you just sell it to the grid for whatever gas generated electricity is going for. Which is currently still a fucking lot. Thanks Russia.

Nah, the power company likes the profits from nuclear way better.

The secret is that they can bill the ratepayers for all the cost overruns, while keeping the extra profits on the cost-plus construction contract for the shareholders.

(Source: I'm a Georgia Power ratepayer being absolutely reamed for Plant Vogtle 3 and 4, and the Georgia Public Service Commission isn't doing a single goddamned thing to hold Georgia Power to account or to help people like me.)

Stop all the hate for nuclear. It's just a way for the fossil fuel industry to cause infighting among those of us who care about the climate. If we can make energy free or close to it, we should. The closer everything comes to being free the better.

Nuclear is the future. Stop trying to deny it. We should all be running it by now this shit was made like 60 years ago. But no, we'll just eat smog I guess. Damn my feeds are kind of depressing today.

[–] [email protected] 12 points 1 year ago (1 children)

Fission is today. Fusion is the future.

[–] Sanctus 10 points 1 year ago (7 children)

It blows my mind we are avoiding this? You want jobs? Clean stable energy? Its fucken here dude. Just build some plants. They only need to be properly maintained to avoid disaster. If we truly are an intelligent species that should be easy as hell.

[–] [email protected] 16 points 1 year ago (1 children)

They only need to be properly maintained

And there is the issue.

More profitable AND safer. Humans are too stupid, lazy and bureaucratic to use nuclear.

Until we are able to sort out the cost/tech to make a green-sourced grid (such that the role of utilities is to capture surpluses from when the sun shines and the wind blows and sell it back when transient sources aren't producing) nuclear is going to be an important part of a non-carbon-producing energy portfolio.

Already it's cheaper to bring new solar and wind online than any other sort of electrical production; the fact that those are transient supply sources is the last major obstacle to phasing carbon fuels entirely out of the grid. If nuclear can be brought safely online it could mean pushing the use of fossil energy entirely into use cases where energy density is critical (like military aviation)

[–] [email protected] 8 points 1 year ago (6 children)

If we had an energy system owned by the people and not ran for profits, nuclear would be a viable, and probably even the preferred, option. We do not. We're probably going to have to fix that to get a practical and reliable clean energy grid.

If we measured the amount of destruction to our environment that fossil fuels cost long-term I bet they'd stop being profitable really quick.

Its a relatively recent development however since the panels and turbines got quite a bit cheaper. Nowadays solar/wind ends up fairly similar and Nuclear is about 3x the price (with gas being more and coal being nearly 7x more). That is only some of the story as you need some storage as well but it doesn't end up in favour of Nuclear. 15 years ago Nuclear was a clear win, its just not anymore the price of Solar come down fast.

Profit doesn't equal good. Renewables take a lot of materials and fabrication to upkeep. Im sure theres more money to be made in renewable than there is in nuclear, that doesn't imply one is better than the other.

This is such a weird thing to research because a government (or governments) can directly or almost directly control what is profitable in a society based upon what is needed.

What about when the grid is almost entirely renewables? Is nuclear cheaper than just storage? What about storage one it's already been implemented to the point of resource scarcity?

[–] zik 9 points 1 year ago* (last edited 1 year ago) (3 children)

No, nuclear is always more expensive in real world conditions. Places with mostly renewables plus in-fill from batteries and transient gas generation are a lot cheaper than nuclear. eg. South Australia.
