I heard automation is an upcoming focus, so just incase the idea hasn't been suggested yet -
Have some sensors or switches that can be set up to turn off downstream power depending on various factors.
The two that i think make the most sense early game are power generation, let the sensor choose a threshold (ie +3.0/s) and if ti drops below that then it shuts off the downstream connection.
Secondly time of day - so you can shut machines down when the sun is down if you only want stuff to try and run on solar (things like drills will keep running till your batteries are drained for example)
Later on you might be able to have other things like water levels and o2 levels and such, but im not far enough in the game yet to know what all the things are.
It would also be nice to just have a switch that can turn off downstream power, so you can manually shut down machines and turn them back on quickly without needing to rewire them each time.
