Not if John Goodenough battery, solid state, can really work, even than not so fantastic as he said for energy density, since they managed to create a solid state battery using sodium and workable at fine temperatures and lasting dozen times more charge cycles.
I imagine in 20 years a lot of solar cars, using such batteries, and many homes with solar panels, all connected in grid.
Battery don't need to have the same energy densit of gasoline. Anyway the gasoline have 1/3 of the energy reported, since the reported value it's for the bunring it with oxigen, and the gasoline itself only have 1/3 of the energy of this combination of gasoline and oxigen.
Second the electric motor it's much more efficiente (up to 98%) than combustion engine of cars (about 25%).

But to go totally off the big grid you need batteries, but the cost of the batteries and their replacement makes it cost prohibitive.
