> if we start digging into the core and allowing energy to escape faster, we would effectively speed it up, right? I don't think we're even digging through the crust - there'd still be the mantle (~100x thicker) before we got to the core. In numbers, I believe the deepest borehole is ~12km deep... and the Earth has a radius of >6000km. We're barely scratching the surface.
My concern is fundamentally whether or not we are siphoning energy out of the core faster than it would otherwise escape. Since the layers are directly connected, it doesn't sound like to me that you'd have to dig into the very core for that to happen. Of course at the current state of affairs the effects are miniscule, but it doesn't sound like a very good investment as something to potentially scale up in the futur…

Granted, the cost for solar and wind fail to account for the cost of storage to accommodate their intermittency. If your country has hydroelectric dams, then that works. But for the rest that don't have the right geography for hydro, they burn fossil fuels. Nuclear provides a path for decarbonization. Solar and wind do not, until a massive breakthrough in energy storage is invented. And nobody knows when that will ha…
We don't need massive breakthroughs in energy storage. And the goal is overall carbon-neutral, not carbon-zero. And other than wind and solar, we also have hydro and geo-thermal. The latter might become a very important part of the mix, as it would be relatively easy to securely and relatively cheaply deploy a lot of small scale heat pump power plants, requiring fewer massive power line installations, with the added…
Decarbonization is maaaybe 1/4 of the way there, but folks seem to like to spin it as 90%.

What exactly am I making up? Timberland owners (at least in my experience owning a lot of timberland) need to time market conditions quite a bit to make a profit. If someone is lucky, an offer for the land CAN coincide with good market conditions for the specific timber they have at the state they have it, but that is far from guaranteed. All the species I happen to have a good stock of went crazy high earlier last y…
And it is pointless to talk about when there is no need to build there.
Which is not a very gracious spelling of "Sorry, my comment you replied to was stupid; I retract it and apologize", which I'm sure was what you were trying to convey.

All these arguments are moot, see the research: https://whatisnuclear.com/economics.html https://whatisnuclear.com/fukushima.html ...etc.
See this nuclear positive website that doesn't have an imprint (I can find on mobile). I wouldn't bcall it research either. Summary would probably be fair.
You mean an "Impressum"? That's just some weird thing that AFAIK (almost?) only German Web sites have, because they're required to by German law. The vast majority of sites on the World Wide Web get by just fine without it; it's not like that's some kind of minimum requirement for a reputable site.

There's no reason to assume that building the same nuclear reactor design multiple time will maintain the same cost or decrease. Even with the supposedly successful French nuclear program, costs increased over time, there was negative learning: https://www.sciencedirect.com/science/article/abs/pii/S03014... There's huge huge risk in choosing a particular design and building even one of it, because we don't know if it…
The negative learning rate is a strong signal of interference by the regulators. More than anything else it shows how excessive safety regulations are strangled the industry. 1970s nuclear safety standards, despite it all, were still better than the energy strategy the world adopted from 1970-2020. Killing off nuclear in search of a perfect power system was a stupid strategy, and failed. The only unfortunate point of…
Maybe you have some actual knowledge, but I have never found somebody who says that regulations are the problem but has any concrete suggestions for changing regulations. It's just a vague gut feeling. And in the case of France I doubt it applies at all.
Construction is not like manufacturing, it does not see continual productivity improvements like manufacturing does:
https://www.nist.gov/publications/measuring-and-improving-us...
As an energy source whose costs are primarily construction related, we would not expect to see it falling in cost over time. We would expect that energy sources whose costs are dominated by manufacturing to outcompete nuclear as time passes.

No, it's not sarcasm — I would appreciate it if you would be a little more generous when interpreting my remark. The proliferation problem is exacerbated incrementally by every additional plant in every additional country — including this one. The issue is not Finland in particular developing nuclear weapons, but any country developing nuclear weapons — especially a country governed by an autocracy. Or a country that…
The countries which are least trustworthy wrt nuclear weapons are the ones that aren't going to ask the public's permission. An autocracy doesn't need to power itself by nuclear plants in order to have nuclear weapons. On the other hand having a sustainable, clean source of power not tied to autocratic regimes lowers the leverage those regimes hold over democratic countries. In my particular country, a major chunk of…
But yet [your country] is not lost?
Re: Finland starts much-delayed nuclear plant, brings respite to power market

Is this also sarcasm? So you're saying that building this plant has increase the chance Finland will try to acquire Nuclear weapons? And Russia has nukes purely due to political and military reasons, they'd still have more than enough of them if they mostly started closing/stopped building new plants after Chernobyl.
I don't think it's sarcasm. Maybe North Korea is a better example. It would probably just be "Korea" if they didn't have nukes, but you can't exactly go in and overthrow the government when they can just wipe out all human life on the peninsula in an instant. (People get upset at the implication that one country would take over another country, but the people of North Korea would probably not be worse off if that hap…
If anyone is upset that the people of the German "Democratic" Republic got to join the rest of "We, the people" in a free Federal Republic, they're cordially invited to go fuck themselves.
The same would go ten times over for anyone feeling that way about the much more oppressed North Koreans.

> It would probably just be "Korea" if they didn't have nukes Their first nuclear test was in 2006. Even their production of refined uranium and plutonium only began in the 80s, decades after the war came to a standstill.
Kind of a case of ignoring geopolitical debt, I guess. Anybody who wants to fix the problem today has an impossible task that was once possible.

The possibility seems remote right now and I dislike the inflammatory framing, but I think this touches on one of fundamental drawbacks of nuclear power: it is hard to engineer plants to guard against catastrophe because there's a lot of energy stored in an inherently dangerous form. Hydroelectric power is often similarly vulnerable: you can engineer the dam to hold, but when something outside of tolerances appears,…

Wind turbines work on average at 18-30% efficiency in Finland. The nadir efficiency is roughly at 6%. You'd need to build 1300+ 3MW wind turbines to match the average production of Olkiluoto 3, or 7000+ turbines to guarantee the same level of constant output that this plant puts out reliably. We had this "too slow to build" -argument 15 years ago, but no other renewables have delivered. We built 67 new windmills in 2…
Err..... Not exactly! https://ourworldindata.org/grapher/nuclear-renewables-electr...
You can see that the total share of renewables has climbed significantly, but production is heavily weighted on summer months when there is no shortage of electricity. https://ourworldindata.org/grapher/nuclear-renewables-electr...
These numbers are all insignificant, tho. Finland needs to build roughly 22-35GW of renewable/nuclear power to get rid of carbon based energy, and we're nowhere near.
The clear answer is that we need both wind and nuclear – a LOT of both, but I doubt we'll do neither in sufficient quantity.
