Greta ThunbergJan 11, 2023

This Saturday 14/1 I will join activists in Lützerath to defend the village and stop the coalmine. Join us at 12.00 to protect life, and put people over profit!

The science is clear, the most affected people are clear: no more fossil fuels!

The worst is that is would have been entirely avoidable if Germany did not choose to stop its Nuclear powerplant and depend on russian gas #energiewende.

@adev @gretathunberg France has 75% nuclear power in normal years, but still generate about the same amount of power per capita as Germany from natural gas. They have to use natural gas (and hydro) for load following, since it is too expensive and slow to do that with nuclear. If the fuel rods become too unevenly spent from having the control rods half way up for too long, the reactor won't run for full capacity towards the end of the fuel cycle, and they won't have the effect they depend on.

Note: I am nowhere near a professional in this area and you should probably ask someone like @gregdt for more information.

But from my understanding:

- What you name there is called "dentelle" in French: They do use natural gas to follow the intra-day variation of consumption indeed because it's "easier"

@sturle @gretathunberg

- There is a scenario from @voixdunucleaire to manages "dentelle" entirely by pump hydro storage + Nuclear without any dependency on fossil. [1]

- Consumptiom of Germany of fossil fuel is far beyond "just" Gas. It includes Coal and Lignite. Where at the opposite, France is mainly Gas. [2]

- Fossil fuel raw capacity (GW available) is massively higher in case of full renewable scenario (like in Germany) than it is in a scenario that keeps nuclear (like in France, Spain, Sweden, UK, Finland). This is mainly due to the fact the intermittency of RN need to be compensated.

So yes. The best short/medium/(long) term solution if you want to stop coal is to stay nuclear

@adev @gretathunberg @voixdunucleaire Please take into consideration the fact that many tpes f renewable energy can be perfectly regulated to follow load.

25% of the gas consumed in Denmark is biomethane injected into the normal gas grid. It is produced from mainly pig manure, which become a better fertilizer during the process.

Hydro, geothermal, sustainable biomass, to name a few others.

And a lot of storage tech which hasn't been much researched, like carnot batteries.
