About your edit: That is the plot of the excellent early access game "Dyson Sphere Project".
In the game backstory humanity became entirely digital, but found out AFTER that, the energy requeriments are staggering, so they send the player in a robot body to fix the energy issue. (you start building solar panels and thermoelectric powerplants and whatnot until you can build a dyson swarm and finally a dyson sphere).
