demiare I don't understand how I made a mistake, I chose from the techs given to me. Its turn 42 and I have no solar and no power
Are you saying that after researching like hospitals and sealed roads(giving me 2 of the 3) I should never research anything again until I discover power plant or solar panels?
Yes.
For min-max gameplay you should ignored hospitals and sealed roads (useless until mid-game), taking only automatic rifles and padded envirosuits until you will get power.
This game is VERY complex. You should either fully read manual (for example it's describe how research work) or carefully study whole UI and tooltips everywhere (as I already'd mentioned - in research tree overview tooltip will told about how research is working and "rule 3". Or you will fail. Don't be mad about it.
This game is more like Dwarf Fortress or Aurora 4X then simply game like Stellaris. You will learn by failing (or studying a lot before playing).
