Minecraft rf generator?

I need a Minecraft Mod that has generators that can generate RF energy. It shouldn't be too big because we only need the generators for the refined storage system

The big reactor mod is good. The mod's smallest reactor is 3x3 blocks. It hardly uses anything

I forgot to say that it must be for 1.14.4

I recommend thermal expansion

P Revier immersive engineering. The wind generators run continuously and you therefore no longer have to worry about them

There are only until 1.12.2
