Where have all the "what do you do when the wind doesn't blow and the sun doesn't shine" commenters gone?

Where are the comments about „molten-salt reactors dont need any of that”. And a closed water loop. China builds them on a desert and we cannot build them anywere in Europe due to plain stupidity.

It's not matter of "can", it's a matter of "how much does it cost?" and "who pays for that?".

Precisely why the Netherlands does not have nuclear power plants. Cheap coal. Cheap oil. Cheap gas. And now cheap wind and solar. They just absolutely cannot math the math which leaves ideology and this ain't France.

That math leaves out externalities when pricing gas, oil and coal. You may have heard of a few fires going on in Europe in addition to nuclear plants shutting down?

Beyond that, those resources are also the lifeline for a dictatorship in the east causing increase defense spending.

There definitely is no such thing as cheap gas, oil or coal for Europeans, all things considered

Don't solar panels have the same problem with heat?

Solar panels decrease in efficiency when hot, but it's not like a complete shutdown.

When your solar panels are hot is noon in the summertime which is when you have way more solar power than you need anyway. Most grids that have substantial solar power are getting saturated with solar power at that time and running everything else at minimum capacity.

>we cannot build them anywere in Europe due to plain stupidity. Economics I think. Nuclear power has gone bankrupt in France already (arguably more than once) and gotten bailed out. Now they produce electricity at a price that's often above market price, with losses covered by the taxpayers. This despite relying on cheap cooling from rivers. Adding more expensive cooling won't help. We've quite recently reached mass…

Solar panels keep getting better and cheaper every year. Can't say the same for nuclear.

I believe this is why the USA recently declared that it's no longer going to follow the "linear no-threshold model" and "as low as reasonable achievable" principle of radiation exposure. In other words they're declaring that a small amount of radiation is good for you. Building a reactor without shielding and with a single open-cycle water loop should reduce costs, right?

(Do you know what else reduces costs? Apparently, putting a foot of graphite at the bottom of your control rods and not paying close attention to a dangerously unstable reactor during an unusual experiment. These aren't official American policy yet.)

Also, the USA's recent ban on solar electricity equipment should help make other forms more competitive.

> Now they produce electricity at a price that's often above market price Do you have any source? I'm not french and all I can hear from the news is that France's nuclear electricity is cheap, for example: https://thenextweb.com/news/france-energy-advantage-ai-data-... Now I'm curious what the truth is. Are these articles just fake-news trying to ride the AI wave? (not suggesting, just asking)

At this point in time it can be assumed that 90% of everything on the internet is a lie.

French nuclear electricity is cheap because the government subsidizes it to keep it afloat. And because continental European electricity is generally expensive. It probably wouldn't survive in a free market.

Hungary is flat as hell, there's nowhere to build enough hydro storage. But yeah batteries would be nice.

You can do low(er) head pumped hydro storage [0] [0] https://en.wikipedia.org/wiki/Ludington_Pumped_Storage_Power...

Can't speak for Hungary specifically, but the problem with flat terrain wrt hydro storage isn't just elevation difference - which can be offset with flowrate - it's the large surface area to storage and to depth ratios.

Large lake means more losses, mainly due to evaporation, but seepage is also to be expected. Now put this fact in the thread's context: water shortage/stress...

So nuclear isn't the solution after all.

Nuclear without greed is fine. Its only where shortcuts have been taken with cooling that there will be issues.

That seems like a huge disadvantage for nuclear power if you need to guarantee strict ideological commitment to ignore cost-competitiveness not just now but into the future. Renewables and batteries are not only cheaper now but have far less scope for major failures based on some MBA cutting corners in a decade.

> sometimes fossil fuels are a good fit There is simply NO safe level of fossil fuel use.

There’s applications that we still have no alternative for though - e.g. aviation - so we’ll have to accept the burning of hydrocarbons there. Not fossil hydrocarbons forever, of course, but synthetic kerosene might be a thing soon enough.

Yes: the way we should think about that is that we do things like switch to trains and BEVs so we can afford to continue running airplanes while synthetic fuels are being put into production.

i thought it was pretty clear, personally.

It's unsafe so it's never a good fit? That kind of reasoning is just noise. Unsafe for what? Compared to what? What alternatives, given the constraints, exist?

Finding something ideologically inconvenient doesn’t make it noise. There is simply no level of new carbon emissions which isn’t guaranteed to cause expensive problems around the world. That doesn’t mean we can’t switch everything instantly but that means we shouldn’t be building anything new which has a safe alternative — and in the case of electric power generation or cars, that’s especially clear because burning fossil fuels for that is more expensive so you’re paying extra to pollute more.

But doesn't adding a large reservoir mitigate both? You're not pumping the entire reservoir up and down hill every day.
