Denmark is a state-sized grid by US terms. They have the EU to draw on for the same reason US states draw from the two national-scale grids; wind is unlikely to be out across the entire EU. (Night also means lower demand.)

To be clear, Norway has no nuclear. 99% of generation there is hydro. Low wind in Denmark likely means they release more water for a bit; system works as intended.

See my addendum comment about Germany for example. They had to burn coal to keep up with the demand while their 200% overprovisioned renewables could only generate 20% of required electricity.

Today the only countries were renewables worked at close to 50% installed capacity were UK (wind) and Greece (solar). Everywhere else at best wind and solar were at 30% production. The entire Europe was busy burning gas, coal, or hoping that neighbours have enough nuclear and hydro installed.

Yes, this was my mistake. I should've said: propped up by stable energy sources: nuclear (Sweden) and hydro (Norway and Sweden)

Which is up from pretty close to 0% just a few decades ago (example: https://en.wikipedia.org/wiki/Wind_power_in_Germany#/media/F...). We're just getting started; this is a multi-generational megaproject.

You seem to think people are declaring the shift to renewables to be finished. I'm not sure where you obtained that misunderstanding.

People claim there's no need for nuclear, and that all the needs are covered by renewables, we "just" need to maybe overprovision them.

Germany already overprovisioned. 200% of electricity requirements. And yet...

When I point out that even overprovisioning doesn't seem to work, people deflect, deny, stop responding, or reply in non-sequiturs.

So. Given that yesterday renewables in only two countries (Greece) managed to reach 50% of their installed capacity (not all renewables, but different types of renewables), how many renewables need to built to make sure that all of EU needs are met?

You keep saying this, and then you keep saying they don't have enough. These both cannot be true, and Germany's continuing to expand their wind/solar efforts indicate they don't believe they've "overprovisioned" yet.

Germany's plan goes out to the 2050s. Your complaint that they haven't provisioned enough yet is not in good faith.
