then how about putting the energy buffer into the buildings themselves? I.E. if a building is above their ideal energy input it gradually stores power to use in the event its power supply somehow gets cut off, and for the Miners they could stockpile energy when their metal/crystal storage is full, while defense buildings stockpile energy until they need to make use of it (I.E. the laser turrets store energy until they start shooting, the energy shields store energy until they need to repair or (again) their generator gets cut off and will repair more rapidly if they have energy to spare, etc.)
