That remains to be seen. We would need to see what their progress is 5, 10, and then 15 years from now. I think the 2035 target would take a miracle to actually accomplish without Nuclear Power.

> Lux expects the global annual Li-ion manufacturing capacity to more than triple by 2024.
That 2TWh or 45 minutes of storage for the whole world added annually.
With this manufacturing capacity it will be possible to have 2h of storage before 2030, which greatly increases the amount of renewable energy which could be utilized.
I'd say if not 100%, then 80% is realistic. Wind and solar combined make up around 30% already, so it's a question of doubling that number and adding appropriate storage.
Germany is doing better at decarbonization than most countries, in fact, but still attracts a disproportionate amount of flak for "not doing enough".
My cynical side says that this is precisely because they're slowly proving that nuclear isnt a necessary component of decarbonization. They are setting an example that threatens the industry's survival.
