Batteries are great when you need a relatively compact and lightweight source without moving parts and noise. That is, cars, helicopter drones, phones, etc. Batteries still lack the high energy density of fuels like kerosene; you cannot fly a jet plane or rocket on batteries.

Electric power can probably be used to synthesize traditional fuels from carbon dioxide and water, to stay carbon-neutral. Plants can do that but in a quite inefficient manner. A (bio)chemistry breakthrough is badly wanted on this front.
