Wouldn't change much if any at all. Nuclear power was only less than 6% of total energy production in 2022 already. https://de.statista.com/statistik/daten/studie/29295/umfrage...

Coal produce 10% of the energy of Germany right now, it's 60% of the emissions. 5% of nuclear would reduce by a third the Germany emissions by reducing coal usage. > Wouldn't change much if any at all.

Amazing how right you can be and still wrong.

5% of German production is about twice the projected capacity of Hinkley Point C, the only current nuclear plant I remember the name of, so that might cost maybe €60B. The same amount of PV would cost maybe €2B. If you overbuild PV by 300% you still have >€50B cost difference.

You can reach any conclusion if you're willing to disregard price differences of more than 10×. Ditto if you're willing to assume near-zero cost by assuming inexpensive restauration of hardware that's past the end of its design life.

Right now when it is sunny PV panels produce at their peak. May is optimal time for solar energy for the northern hemisphere. Summer reduces efficiency due to heat.

Summer temepratures reduces efficiency of all thermal power plants, including nuclear and coal, since heat engines are more efficient when their cold bath side is held at a lower temperature.

What you wrote is propaganda and not true, are you aware about that?

https://www.reuters.com/business/energy/high-river-temperatu... but you're right, half of them were down for other reasons, too: https://www.nytimes.com/2022/11/15/business/nuclear-power-fr...

Do you agree with the content in the article you sent ?

It says it's for "water too hot" not "lack of water", a nuclear plant can be retrofitted with cooling tower to not heat up the river. This is not done for cost reasons, we are already overproducing when theses nuclear plant need to shut down due to temperature.

> Kpler analyst Emeric de Vigan said the restrictions were likely to have little effect on output in practice

The article you cite, mention an expert that says it will have "little effect on output", you make it as a big problem.

And as the article says, France is still a net exporter at this climate, we export to countries that need a lot of electricity in the night, like Germany, exports have been massive theses days https://www.rte-france.com/en/eco2mix/cross-border-electrici... , despite germany attempt to sabotage our industry.

This is the installed capacity. The capacity factor in winter for solar is below 10%. Nuclear is typically at more than 90% in winter. The target we are speaking is CO2 emitted, it already reached the "target" in france, with less than 60gCO2/kwh to provide electricity the whole year, to the whole grid. > but that doesn't mean that it is the right technology for other nations to go with now you propose something that…

This is the energy generated. Every euro spend on nuclear is a euro not spend on something that's giving you 2-3x as much energy generated. Rewewables have been called "infeasible" at 5%, at 25% at 50%, now we're at 60%. I'm prette sure you'll yell "infeasible" even if we're running at 100%...

The numbers are too low. We have seen a surge in solar panels on balconies (~10% in this higher income neighborhood), which isn't taken into account. Also several people in my family have their roof full for their own consumtion + EV, this also not taken into account. We recently went on the Autobahn for a 1000km journey, and you can see some solar farms, but very few. There is still a huge potential. Solar will also…

This doesn't take into account the cost associated with storing the energy, or having alternate energy source to fill in the gaps.

You say that the cost of renevables and energy storage combined don't include the cost associated with storing the energy? Wild take.

The graph you linked doesn't take it into account.

Of course I'm wrong, I think differently than your beliefs, Atheist were wrong too.

Still better than being a nuclear reactor operator.

Why? I would expect it to be comparatively chill, as it should be running mostly constant and reliable?

It's currently 13:20 and sunny, Germany is at 183g/gCO2eq, not good.

But on the right track. We're building the solar equivalent of the total cumulative nuclear capacity germany has ever build every 3 years. If we manage to hold off regressive forces that are trying to derail the current trajectory with whataboutism of nuclear and fusion, we might actually make it to CO2 neutrality in a reasonable timeframe.

“On the right track” would be “we know we’re going to make it without mass extinction of humans”. Currently I’m not so sure and I doubt anyone knows.

We’re making changes, but the course correction haven’t been sufficient so far and it remains to be seen if we will be able to do enough fast enough to avoid said cataclysm.

Here what I think about it again: You didn't read the article I sent, it show you don't care about what it says but you try to attack the article because you dislike what it say. The article state it's source is cicero, a... german magazine. https://www.cicero.de/innenpolitik/robert-habeck-akten-atomk...

Cicero is a well-known, "conservative" (at best) to political rather right-wing magazine. It's not any better in terms of neutrality than the Telegraph. Find a reputable source and we can talk about it. And please don't come up with the Merkur or some other yellow-press who covered that nonsense for clicks.

So… did you read the article? Or are you going to dismiss it because you disagree with the magazines overall politics?
