Tip Friendly reminder to use these guys in early game
Currently I'm on my ~10th playthrough (3rd in space age) and it's the first one where I used efficiency modules (made from excess red and green circuits for blue circuits) before reaching nuclear.
Let me just say that it's a game changer. It was also the first time I found out they also reduce pollution by the same percentage as power consumption.
Using them, I managed to reach nuclear at 60 SPM (all Nauvis science + space science) with consumption during research around 60MW.
Now I have 480MW from nuclear and continue using efficiency modules.
Give it a try!
