Since releasing my oil video I've had so many people claiming that renewables will never work and we need nuclear power instead.

What's odd is that almost all of the messages mention that nuclear power is the only solution for the "base load".

I have a degree in Electrical Engineering and I took several nuclear science electives. I like nuclear energy. But I received so much "base load" gaslighting that I started to doubt my own understanding of the situation.

@notjustbikes I used to be very pro-nuclear. While.I still think removing power plants today for ecological reasons is highly counter productive, I have significantly changed my position overall. So many countries don't have the ability to deploy nuclear. They don't have any already, building the expertise takes decades, and can be the cause of geopolitical tensions (see Iran...).
@notjustbikes Since all these countries will have to make do with just renewables, we will have to solve the base load issue without nuclear, so even for countries with existing nuclear infrastructure, it's essentially going to be obsolete. And economically it seems much better to develop a local renewable industry that we can export globally, rather than a nuclear one that is going to be obsolete by the end of he century (and if it isn't we're doomed anyways)

@sgued @notjustbikes it was an excellent option we should have deployed more of in the 90's.

But it isn't the 90's any more.

@LovesTha Yeah, that's the thing.

When I was studying nuclear energy in University (because I was a huge proponent of it) it was the 90s, and we should've built a shitload of nuclear reactors then. It made sense.

But now? Nuclear rectors take ages to construct and they will not be as cheap as renewables.

Nuclear reactors may still make sense for powering heavy industrial applications though.

@notjustbikes @LovesTha a critical part of nuclear power viability is the ancillary uses (having the capacity to build nuclear weapons or support nuclear powered infrastructure eg submarines or aircraft carriers).
Ukraine has illustrated that the massive and expensive single target infrastructure counter acts a lots of these consideration (with asymmetric cost, vulnerability and localised contamination risk)
Renewables with storage already win on cost, decentralized / defuse vulnerability, and load response capacity, and we are not yet at the bottom of the cost curve.
I suspect the nuclear age is already historic.

@notjustbikes @LovesTha

There was and interesting conversation between Robert Scheer and Thomas Bass (who wrote a book on Fukshima)

I have not fully investigated the assertions from Thomas, but he posits that nuclear was never viable, it was only ever a subsidy to enable weapons, there are obviously other positive and negative outcomes from nuclear, but this seems credible from my cursory understanding.

@houba @notjustbikes I haven't listened, but i would expect nuclear to be much more competitive if all externalities are included. Yes nuclear waste is bad, but a too hot planet is pretty bad too.

@LovesTha @notjustbikes

If I remember the figures from Thomas, it was a while since I listened to it, the cost of nuclear excluding build, disposal, and decommissioning is about $170 /MWh where solar is about $40 /MWh inclusive. *I will probably listen to it again today and correct later.*

He describes it as "the most expensive way to boil water."

*I edited from what Thomas said in the recording, I had guessed too low on nuclear and too high on solar.*

@houba @notjustbikes I can't believe the price for solar in the 90s was anywhere near that cheap.

@LovesTha @notjustbikes

I don't think he is talking about the 90s

I feel this may be 2023-5 estimates.

This paper estimates solar at $45/MWh for large scale solar. I don't know where Thomas gets the nuclear figure from.

@sgued @notjustbikes I agree, new reactors just don't make financial sense any more.
And it will take so long to build them that renewables will be even more cheap.

@sgued @notjustbikes

I used to be very pro-nuclear, but I am now very pro-fusion.

I have a number of remote nuclear fusion receivers on the roof of my house, and they are netting me around 7 MWh/year at zero running cost.

@isotopp

The remote fusion collection contraptions don't have any moving part either. I think this is important, maintenance-wise.
@sgued @notjustbikes

@datenhalde @isotopp @sgued @notjustbikes I never heard of this and tried to find anything on remote nuclear reception. Could you please share a link or more info? Thanks!

@spiegelmix @datenhalde @isotopp @sgued @notjustbikes

It's a fancy way of saying "solar".

The sun generates energy via nuclear fusion. And photovoltaic modules and such collect the energy.

@sgued

Have you considered geopolitical tensions in an industry where 85% of the whole supply chain (!) is controlled by a single authoritarian country?

That’s the PV market today and includes not only the panels but also backdoored inverters…

Plenty of other countries and companies can produce panels. LG, who are Korean, make a lot of PV.

Also, once purchased, they keep running without requiring approval and new shipments from an authoritarian country, so your fears are somewhat overblown.

@kravietz @sgued

@futuresprog

1) ā€œCan produceā€ != ā€œdo produceā€
2) 85% supply chain control means even if you intend start your own production, you still depend on China for resources… which they can cut at any time, as they occasionally do with rare earth metals etc
3) moving production back to EU means cost increase because you no longer leverage Chinese forced labour, poor environmental standards, subsidies and low CO2 tax

Which are the reasons why China built that supply chain dependency in the first place 🤷

@kravietz @futuresprog

So you want more fossil or what?

There is no basis for any geopolitical tension between the EU and China. Most of it was concocted by the US, starting with Trump, then with Biden turbocharging it.

The EU has little to lose and everything to gain by leaning more into solar weaning itself off of both Russian and US machinations.

Besides, the EU (Germany) had a world leading solar industry before either through gross mismanagement or malice it tanked its own industry.

@largo

So you want more fossil or what?

No, precisely that’s why I want more nuclear power combined with renewables in EU so we can actually finish decarbonisation rather than wholesale importing PV from China and pretend their CO2 doesn’t count.

@futuresprog

@kravietz @futuresprog If you think the supply chain of renewables is problematic, you should check the supply chain for nuclear energy.

@MyLittleMetroid @futuresprog

Well, I did! And it looks much better.

One reason is that typical volume of nuclear fuel is counted in tens of tons, while typical volume of resources for PV industry is counted in millions of tons due to its significantly lower energy density. It’s therefore easy to secure fuel for a nuclear power plan - you just send one cargo aircraft or ship. For the other you need to secure the whole logistics for continuous delivery of millions of tons of the resource.

Oh you muppet.

You’re telling me because I have Korean-made solar panels installed on my house and gathering renewable energy that I currently rely on China and forced labour? Get out of here.

What are you proposing? That I get rid of my solar installation and import some diesel from Saudi Arabia and support Mohammed Bone Saw?

Goddamn stupidest thing I’ve read today. You should be ashamed.

@kravietz

I see you’re a supporter of nuclear energy. You might have missed the first post in this thread about how building new nuclear plants is not something that happens anymore realistically.

Also, I’m in nuclear-free Aotearoa, so that will never happen.

New power capacity for the home owner either comes from solar panels, which can be imported from Korea, or it comes from diesel generation on the other side of the globe, supporting the worst repressive regime you can imagine.

@kravietz

@futuresprog

I’m supporter of decarbonisation.

Nuclear power is the only low-carbon electricity generation that is dispatchable and does not depend on geography.

Unlike the PV & wind fans, I’m not going to tell you what you should be using in Aotearoa. You should use whatever works in your geographic landscape and lattitude and delivers decarbonisation.

I’m also a supporter of decarbonisation, and despite your assurances you most definitely are telling other people what to do.

Nuclear power doesn’t work regardless of geography. Nuclear power isn’t viable here due to culture, geology, and … geography.

@kravietz

@futuresprog

IF you want decarbonisation, THEN you look at IPCC & UNECE data and choose technology that works in your geography.

The part where I step in is when people deny IPCC & UNECE data, be it in causes of the climate change or the role of nuclear in decarbonisation. Funny thing the former are rare here, but frequent on Twitter, but vice versa for the latter šŸ˜„ But one can’t say ā€œI follow scienceā€ but then cherry-pick from IPCC ā€œbecause I feel soā€.

@kravietz @sgued Even Chinese paid-up politburo member inverters don't need a network connection... if you want to monitor them you can use RS485 typically and do it locally.
@kravietz @sgued I very honestly thought you were talking about uranium. 😬
