Mark Jacobson leads a team that says California and other states can get to 100-percent renewable power by 2050. Celebrity activists Mark Ruffalo and Leonardo DiCaprio are backing him.

But critics say the theoretical plan doesn’t consider the hard realities of the power grid and that renewables are sometimes oversold. California recently passed a law requiring half of the state’s power be renewable by 2030.

Should the state be more ambitious to battle climate disruption? What does PG&E think about going all-in on renewable power?
