Agreed! Already the Washington Post is whining about how California has more solar power than they know what to do with - sometimes. But it's not a "problem": it's an opportunity.
Since I'm a worrier, I note that only 20% of world energy production is used for electricity, and a lot of the other uses are harder to decarbonize! For example about 25% is used for transportation. We can convert cars and trains to electric, trucks are harder but doable, ships are still harder, and airplanes are still harder: we could use biofuels for those to make them carbon-neutral, theoretically. And so on... we need to do everything.
And all this decarbonization is just part of grappling with the Anthropocene: how we're now in control of all the biogeochemical cycles on Earth, whether we like it or not.
