> I don't see how wind and solar don't make sense. Wind and solar make total sense. All we need to do is overbuild wind/solar generation + invest in energy storage capacity. This can be done relatively quickly, certainly much more quickly than building new nuclear plants.

What kind of grid scale storage can be built quickly?

hydro, but thats also something we do not built because it's not environment friendly (takes a lot of space and kills species living there and might need to move people). keep in mind we are not china they basically do everything lately to grow their energy, hydro, nuclear, wind, solar the full mix, something which would not be possible in germany, because people would go full madness, heck even wind already is something that some people do not like.

6. Wholesale electricity rates have increased from 50 Euros/mwh to 250 Euros/mwh over the course of the last year. This isn't about averages. It's about meeting demand, which is especially important during the winter heating season.

Electric heating is extremely uncommon in Germany (like 1-2 % of households use it).

Paying 41c/kWh for ökostrom / 100% renewable energy here, and doing some mining with two 150W Radeon 6000 GPUs to keep this computer room warm goes a long way to making it cost effective.

The sentiment on HN on this topic has traditionally been negative, and comments that support the move get downvoted. The fear of nuclear energy is deeply rooted in Germany and cannot be simply ignored. The "Anti AKW" (anti nuclear power) movement was huge since the 80s, it predates the fear of global warming, and it was at the core of what became the Green party. And Merkel, who has a doctorate quantum chemistry, cam…

Merkel... Did not come to the conclusion that nuclear power is too risky. She wanted to do more nuclear, well aware of CO2, but Fukushima happened (killing zero victims, but hey) and she saw her policy would get her voted out office, and no potential replacement was going to do better, so she folded, in the hope that large investment in renewables would help. It didn't, because a renewable world is a 18th century wor…

> She wanted to do more nuclear

This is a lie.

Before Fukushima she only moved the nuclear exit a few years back.

You can't decide when the wind blow and when the sun shines. And you can't either decide when people turn on their washing machine. So it is obvious there is a problem

So the thing about the earth is that it's big. If you have a big enough grid, it will be sunny and windy over a fairly consistent portion of that area.

We don't have a planetary grid (yet, at least). If there's a high pressure system across Europe, the whole continent can have low wind. This usually comes with either very high temperatures (in summer) or very low temperatures (in winter) which further stresses the system.

Spot markets be spotting, we can play this game all day long.

This is insane to me. Nuclear is the best long-term option for ecologically-friendly energy generation. This is absolutely a bad move, and the coal industry has done a great job of demonizing nuclear power.

Well, Germany's wind was done without a thought about how to implement storage; it did not have to; it was a perfect egotistic game-theoretic play: The EU energy market mandates that wind and solar production must be bought before everything else. What happens at the moment is France's nuclear reduces production when Germany's wind is over-producing; there is no energy storage at all. So right now, on top of wind use…

The EU is our battery.

With the current technology, you can't transport electricity more than ~1000 km with acceptable losses.

Atmospheric depressions are bigger than than, and the distance for solar are much bigger as well (other than cloudy, there's day and night).

Germany has the same electricity mix as Germany and it has extremely good SAIDI index compared to all other countries ( https://www.cleanenergywire.org/factsheets/germanys-electric... ). I guess those Germans are just insanely competent, then.

Check precision energy import charts, especially at night in winter. Germany uses other countries as a battery.

Winter nights in Germany are the domain of coastal wind turbines. Off to build more wind farms, then!

Compared to building reactors, anything is quick.
