It seems that there is no config option to change the amount of energy drained passively by several blocks and items. I wanted to adjust the amout used by the 64k storage to be 64 times the amout of the 1k and so on.

Your observation appears to be correct. And no it will not change as it is already somewhat hidden and most likely not obvious to most players.
