Thanks for the suggestion. I will think about it. That said, the power consumption is actually twice of what you see as "miniloader" in the energy consumption screen; there is the second (invisible) inserter that draws the same amount of power.
In my goto game, I have ~ 10,000 miniloaders that draw a total of 70MW (5s stats), 6,000 bulk inserters that draw about 27 MW and 3,000 fast inserters that draw about 13MW . So each miniloader draws about 7kW and each bulk or fast inserter about 4.5kW. Technically, the miniloader is two fast inserters so the power draw is a bit less than twice a fast inserter.
