Eccentricity generators were invented before mass oil or coal use (1830s by Faraday).
We’ve had windmills, hydro, and even animal/human powered devices that could result in turning cranks for the generator to produce electricity - all for centuries at even that point. I would have to look up about when we first used solar to boil water, but I’m guessing there about.

Biomass and windmills perhaps
