One very famous exploit being around for machine Empires for a Long time is the 0 Energy exploit. An Energy deficit only reduces the Mineral Output. Especially machine empire Players can heavily abuse that. They put all their machines on science and alloys, while ignoring the deficite. If they then Need to go to war they have some empty Energy districts Ready, to where they with a few mouseclicks can assign their Pops to solve the Energy issue. Especially with ring World start this strategy is extremely effective.
But all of this can easily be prevented, if Energy is in the future handled like Food for machines/robots. So a negative income of Energy would give an Penalty to robot and machine Pop creation. Maybe even causing a Pop decline, because of robots shutting down due to the lack of Energy. I mean - it works with organic Pops (u really dont want a Food shortage for them).
Additionally it could reduce the stability on ur planets, as Major infrastructure just shuts down without enough Energy (a Food shortage causes a reduced happiness, for machines this would not have any effect, so stability makes more sense).
If Energy deficites would get such penalties for all empire types in General, even organic empire Players would probably start to avoid the 0 Energy exploit, as they probably also have a large robo workforce in their empire. And they would try to avoid that small stability Penalty on top.
Summary:
These two penalties for low Energy, a machine/robo Pop decline and a small stability Penalty, would in my opinion be enough to annihilate the famous 0 Energy exploit and cause the game to be played in a more intended way.
