You can store electricity pretty well either with Pumped-storage hydroelectric plants or with batteries (that recently got way cheaper and more efficient. If you start adding batteries to buildings with solar panels, the buildings can provide electricity for themselves for longer periods of times which will lower energy costs for households.

If you build more Nuclear Power Plants, it is big corporations that profit and not the regular people. I prefer to help regular people.

Far as I know current battery technology just isn't up to it because it relies on rare earth materials that are extracted with processes that are absolutely terrible for the environment.

That's true for batteries that have to be lightweight. There are salt water batteries that do not require any (or a lot) rare earth materials. They are about twice as heavy if I remember correctly, but for a house that doesn't matter a lot. And the good thing is that the more batteries are used in houses, the better and more efficient they get.

Salt batteries?! Huh, that's neat, I learnded a thing today thanks to you.

Dug up some info on them. Apparently their problem is that they don't have high discharge or charge currents and they need some energy to keep their temperature, but in cases where those are OK they definitely seem promising.

I just figured out that they are called "Aqueous Hybrid Ion Battery" in English, so they are not the molten ones.

I didn't find a lot about them, but this website seems to have an overview about them (although they are the main manufacturer of the batteries, so they are probably biased): https://www.aquionenergy.com/technology/aqueous-hybrid-ion-ahi/#What_Are_Saltwater_Batteries_and_How_Are_They_Different
