Almost every article seems to come around to saying "and nuclear power would be great", even when it starts with some solar power invention.
Earlier quoted context omitted.
The German grid does not rely on nuclear power from France. Germany is a net exporter. Of course, with an European electricity network, there is a lot of electricity moved around every day, often reversing directions in a few hours, depending on local needs and production.
It is overall a net exporter but in winter when there is no wind, Germany rely more on its neighborhood. Average are misleading.
Solar (photovoltaic) has its maximum around noon, when there is high demand.
The irony is that in summer, it has happened in several warm years now that nuclear power plants in France had to shut down - they are cooled by rivers and when the water level becomes too low, they need to shut off to maintain safety and avoid ecological damage. These are the times when Germany exports most electricity to France.

France has one of the lowest number of coal plants compared to other European countries. The links on the left of the page let you filter the map into different data sets.
It's weird of the article gives plenty of direct citations from nuclear operators, while at the same time acting like French 40+ year old fission tech doesn't have any issues [0] or sustainability problems, and how the French could dare to shut down one of their first reactors. Particularly in the context that most discussions surrounding nuclear fission power generation lead with "modern designs and reactors being s…
> Afaik originally the life-span for most reactors of that kind was 40 years It is not. That number was made so that EDF would get a proper return of investment. Some plants based on the same design have been granted lifespan to 60 years in the US. > how far past that are we willing to go? As long as its safe. Why throw away something that works, is safe and reliable on the counts that some folks put out a number?
Nor, for that matter, should the most lenient regulation always dictate other countries'. That could just result in endless ping-pong of extensions, and it make lobbying so much easier if you only needed to convince one country and then shame all others into following.

These stories are always very nice and the plants cost effective, but are they true? Pakistan had a 100MW solar powerplant built for them. It actually ended up producing 18MW and required extensive amounts of water to clean the dust off of the panels.[0] I'm sure they were also told that renewables are cheap and will be great, but somehow everyone missed this.

There will be failures on the way to a fully renewable powered grid. India just turned up a 750MW facility successfully [1]. 70% of Texas coal plants are at risk of decommissioning as early as 2022 due to the amount of solar generation in the pipeline [2]. Spain is years ahead of schedule in coal decommissioning due to low cost renewables and pumped hydro storage capabilities being developed [3]. The UK is rapidly de…
That struck me as odd, because Denmark is flat as a pancake - it's basically an overgrown sandbank laid down by Norway's fjords. But the article explains that the cable will carry power from Norwegian hydro plants, which for some reason comes via Denmark. There is a direct cable from Norway to the UK, but i suppose this adds some redundancy, which is good. And, as the article notes, allows the UK to export surplus power (from wind?) to Denmark.
On Denmark being flat, here is its highest point - note that in the photo, the highest point isn't visible, because it's behind a barn:
Then it has not been reversed by the current ruling party.

Correct. Quite a bit of offshore wind potential Great Britain.

1) It's not one of the first French reactors by a long shot. It's actually a licensed American design.
2) More modern designs being better does not mean that previous ones are unusable, particularly when they've been built and are just sitting there. Stupid car analogy: a better car being sold with better crash test ratings does not mean you're going to die if you drive last year's model.
3) Life-span is a licensing issue. Lifetime extensions are common for reactors and designs without issues, which Fessenheim did not have. The fact that it's not automatic means that there is an in-depth study of the state of the reactor before the extension being approved. Reactors with the exact same design in the US have been extended to 80 years.
4) Your source is rubbish (and for reasons that stray far away from the topic so I'll leave it at that).

German winters are quite windy, especially near the coast. Solar (photovoltaic) has its maximum around noon, when there is high demand.

We have a independent national authority (ASN ~ Nuclear Safety Authority) which is tasked to assess the security of all nuclear power plants and certifies them for periods of 10y. The plant that is being closed was certified by the ASN. The 40y lifespan was the MINIMUM certified lifespan of the power plant. It could very well run for another 40y. These kinds of equipment are modernised every 10 years during the shudo…
You have a very focused elite building system in which the big universities creating the future members of the elite are heavily financed and influenced by pro-nuclear organizations. That goes especially for politicans, but includes engineers. The pro-nuclear propaganda repeated by the people that go through this is frightening, many of them are completely brainwashed. In no way can the ASN be really independent, as…
But that's not what happened. The anti-nuclear team won and we collectively made the responsible decision to fill our atmosphere with CO2 instead. Yay?
