You underestimate how making something illegal can stop the thing in that country. Look at a place like Germany, blocking fracking and nuclear power and now reliant on Russian gas.

Germany needs north of 10TWh of batteries to sunset _gas_ generation.

If you're looking for a renewables success story, Germany ain't it.

> Germany needs north of 10TWh of batteries to sunset _gas_ generation.

Citation? Because the EU intends to phase out Russian gas entirely by 2027. I'm not too concerned about Germany consuming non Russian LNG at this time as they continue to deploy renewables and batteries (GP said "and now reliant on Russian gas." in their comment above). Germany is now getting almost two-thirds of its power from renewables; if that isn't a success story, I don't know what is.

(edit: Supermancho wrote in a deleted comment about energy demand destruction due to German de-industrialization, but I'm unsure if that energy demand should be forecasted in the future without good data about potential re-industrialization in the future creating said energy demand)

Yes, by replacing it with natgas from Azerbaijan, Qatar, and other wonderful countries.

I'm kinda jaded about this whole topic because it exposes the utter hypocrisy of Germany's Greens.

But long story short, Germany can get Dunkelflaute. Long periods of time in winter when renewable generation falls to about 10% of the _normal_ generation for that time period. A once-in-100-years event is a full month of sustained Dunkelflaute. And this is not a hand-wavy theory. For example, in 2019 there was a 10-day sustained Dunkelflaute: https://energy-charts.info/charts/price_spot_market/chart.ht... - look at the period from 17 to 26 Jan. And as you see, they also coincide with heightened energy consumption, which will become even _worse_ as Germany switches to heat pumps for heating.

The current plan for these is to build more natgas powerplants (German government had to _subsidize_ them directly). With noises about magic "hydrogen".

What do you suggest? Spending 10x as much on nuclear power subsidies and hopefully getting some plants finished in the 2040s?
> Spending 10x as much on nuclear power subsidies and hopefully getting some plants finished in the 2040s?

Here's the thing. If Germany had spent on nuclear the same amount of money it has spent (so far) on renewables, then it could have had 100% carbon-free electricity and heating. With lower energy prices than now.

So yes. Nuclear all the way.

Instead, we now face the reality where Germany will have to rely on imported natural gas as far as the eye can see. And certainly past 2040. While having one of the highest electricity rates in Europe, so high that they're now depressing the industry. And the plan to fix it is to keep repeating the word "hydrogen" until something happens.

Meanwhile:

> The coalition agreement between the CDU/CSU alliance and the SPD mentions the construction of up to 20 GW of gas-fired power plant capacity by 2030. In June, Reiche announced a first step with a tender volume of between five and ten gigawatts.

Where are you getting that number? Germany produced 488 twh of electricity from all sources over the entire course of 2024. That's a bit over 1 twh per day.
Yep. And Germany needs around 20-30 days of storage. Closer to 20, if some demand response is factored-in.

The study was from 2005. I can find it, if you want.

> A few years ago ”even an hour” of storage was the impossible marker. Then it quickly became ”a day!!!” and now we are at a month without any solar or wind power.

No. The problem has been known for decades, but governments simply ignored it. That's why there's so much noise about hydrogen in Geramny. It's used to whitewash the natural gas.

Who's making anything illegal here
