Renewables make up ~20% of US production.

In the summer months peak usage is near peak solar generation, and usage is as much as 60% higher than minimum daily usage. With the rise of electric cars, a whole lot of usage will be able to be scheduled for times of excess.

There is a lot of current room for renewables to displace carbon. There will probably always be some fossil fuel capacity for peaking plants and battery systems are already being deployed in places.

The point at which we have too many renewables and a gap in generation is a long time off, and possibly with battery systems and demand shifting will never happen. It seems like the time to solve that problem will be measured in decades, there's no need to say renewables aren't a solution now when they can solve a huge portion of the problem starting immediately.
