Detecting insufficient power

[PFQNiet]

Given an electric energy interface that consumes energy, is it sufficient to check entity.status == defines.entity_status.low_power?

Answering my own question here: no.

"low_power" is only triggered when power production falls below 75% of demand, so is insufficient for detecting a lack of power.

Instead, compare `energy` with `electric_buffer_size`. This ratio shows how much demand is being met.
