Hydro emits less carbon per unit of electricity than solar [1]. And drastically less than the renewables + natural gas mix that's used in practice to accommodate renewables' intermittency.

Rooftop solar is not what would be used to power a renewable-powered society; it's more of a con to game current utility rate structures. Hydro will always have a problem with methane emissions.
