How disappointing.
Renewables and storage are far superior, in almost every conceivable metric it’s not funny.
Yet we let conservatives hype up nuclear garbage and carbon recapture as the solution to climate change.
I just don’t see it in terms of fundamentals. We’ve heard this for years, yet countries that have denuclearized have not been able to go full renewables, they have become more dependent on fossil fuels. Storage has just not been able to keep up with demand, baseload is still necessary, and we don’t have other options.
We should absolutely keep investing in renewables and pushing forward, they help. There is no reason at the same time to prevent investment in nuclear and other non-carbon emitting solutions, and if tech companies are willing to foot the bill we shouldn’t complain. Every gigawatt counts at this point.
Storage has just not been able to keep up with demand
The thing is that things are evolving incredibly fast in this space. Renewables have gone from being more expensive than the alternatives to being the cheapest option by a large margin in the span of a decade, and prices are still plummeting. This trend can be observed for both renewables (solar/wind) and different storage technologies. The reason we’re not seeing them online at a large scale yet is that they’ve quite simply just recently become economical to do so. Nuclear does very much not have this property - it trends towards being more expensive over time. Given how long these projects take to build, it’s not out of the question that they will have to shut down on account of being just way too expensive in comparison once the projects are finished.

I generally agree with this - any private actor that wants to build nuclear completely on their own dime and at their own risk should be able to do so. The problem is that this is not what’s happening - these companies often get government funding for these initiatives, which displace investments that could otherwise be going to other more viable solutions.
Take Sweden for example, where the right wing government campaigned on renewables being too woke and that nuclear is the only option. The way they are making nuclear happen is by guaranteeing financing at favourable terms, plus offering guaranteed pricing of the output electricity for these plants. This is going to be massively expensive for tax payers, and is actively making it so that other renewables are not getting built.
Since nuclear takes so much time to build out and is so unviable from a financial perspective, it’s also used as an excuse by fossil fuel interests, that get to stay in business comparatively longer in a scenario where the world tries to pursue nuclear vs where the world pursues renewables.
This is why nuclear support should generally be met with skepsis.
I don’t think we have the time to wait on and expect breakthroughs anymore. A decade ago, sure, but if we end up having major issues with storage and don’t make those breakthroughs 10 years from now, and we start building nuclear plants then, we’re in for an even worse timeline.
Re: government support, sure. If this is a zero sum game and we have to choose one or the other, I’ll probably go renewable. From what I’ve seen, the zero sum mentality itself is the conservative trap. They keep us fighting against each other when we could just say “do both”.
When the IRA passed in the states, there was some amount of funding for nukes. Not a ton, but some. Yet there was skepticism of that, there were calls on the left to defund that among circles I frequented. Why? The support for nukes was much less than renewables and storage, and like an order of magnitude less. It was a hedge - keep investing in alternatives to renewables in case they don’t work out, because we don’t have a crystal ball. So why be divided on this?
The trap isn’t nuclear. It’s division and scarcity thinking. It’s zero-sum politics.
We aren’t waiting for storage breakthroughs though. The current technology is good enough, cheap enough, and faster to build. And meeting the reaction times needed to use renewables correctly.
My understanding is that this is not the case for providing baseload to entire cities, and it’s unlikely to be the case as we increase energy usage (which has been spiking again, thanks to crypto and AI among other things). With current battery tech it would require massive amounts of lithium that would have far greater environmental impact, and still not really cover all needs. And other mechanisms, like stored energy (pumping water, spinning disks)are more theoretical.
I think I would be much more open to the argument once we have a full modern city converted at least partially to 80-90% renewables, with emergency services and other core infrastructure running off of storage instead of existing power plants. If we get there, then I’d probably stop saying we should invest in nuclear in parallel.
And to be clear, we should get there, if possible. We should push forward full throttle, because all of that innovation would be incredible, and I don’t want us to rely solely on one power source at all, be that renewables, nuclear, or whatever else. A smart strategy is have backups, which is why I think we should do both.
I agree with the end statement. We should be doing anything we can to reduce fossil fuels.
We need to think beyond lithium for grid storage. Lithium is great where space is limited as in a house or something similar. There will be multiple technologies that will provide storage on the grid.
I think the bigger problem for nuclear is reaction time. You need plants that can react quickly to compliment renewables. Storage is handling a lot of this but I don’t know if nuclear could. It is my understanding that base load isn’t really a thing.
Nuclear is cool. Has its pros and cons. I don’t know if we should be pushing it so hard. It’s too expensive, takes too long to build, and the decommissioning of a plant takes decades. I just don’t see the future for it.
Hmm, I think of baseload as the following:
- Hospitals and emergency services
- Data centers and communications
- 24 hour transit needs
- 24 hour lighting in cities
- Ventilation, heating/cooling for certain climates
Some of these can be mitigated significantly, but some of these are just things that really can never be down and have to have like 99.999% reliability. As we electrify, I’m going to be looking at storage solutions for these things and seeing if we really feel confident in that up time and having extra reserves. Engineers usually over design, so if we expect to need like 0.1 gigawatts for a week for emergency services during an abnormal weather event, I would want to plan for 1 gigawatt for two weeks for instance.
If that can be done with storage, then that’s awesome, and once we start seeing that roll out widely I will stop advocating for the “do both” strategy.
We’ve heard this for years, yet countries that have denuclearized have not been able to go full renewables, they have become more dependent on fossil fuels.
Which countries are you referring to? Germany for example denuclearized and replaced them with renewables, they didn’t become more dependent on fossil fuels (even if people like to say that).
https://en.m.wikipedia.org/wiki/Energy_in_Germany#/media/File%3AGermany_electricity_production.svg
Fyi Germany has reintroduced coal plants because of the storage issues.
They also relied on Russian gas until Gazprom was ordered to cut over half of the gas flow because of Germany aiding Ukraine.
I don’t think that “reintroduced” is fair wording here. Even if we hadn’t denuclearized, new coal plants would still have been opened. The proportion of coal power to other power also didn’t increase, even in spite of the challenges posed due to Russias war.
Yeah, because it’ll tie budgets up for ten years building it, and in the meantime all the fossil fuel people can tap those final nails into our coffin while they line their pockets.
Ten years? More like twenty. Hinkley point C was started in 2013, supposed to be finished 2023. This year the estimation was corrected to 2029-2031.
Counterpoint: UAE went from zero nuclear energy to producing as much as Denmark or Portugal produce renewables in ten years. From a base of zero nuclear expertise in the country.
It was 13 years and not 10. From your source the bid was won in 2009 and the third reactor started in 2022, with the fourth not ready for that article (middle 2023). Still not 20 years, but 30% above the claimed decade.
The graphic and comparison however are just clickbait. For one it compares a filthy rich oil-state without democracy and Denmark/Portugal where the government can’t just push something like that through. Apart from that it’s made to look like a sudden extreme increase from UAE that might continue that strongly, which it won’t. Starting an NPP of course makes a sudden huge spike, while renewables are more incremental.
This comes as no surprise to me when the source seems to be highly subjective with a huge bias towards UAE:
Those who are critical of these high-energy nations ought to consider that they are not the countries to blame for climate change. Indeed, these countries ought to be applauded for taking measures to wean themselves off of fossil fuels
Of course one of the major oil-states that pushes against measures to slow down the climate change at every chance it gets is not to blame for anything… Sure…
