The problem with batteries (portable stores of electricity) is that electricity is not portable? Really?
Batteries as a portable fuel for large-scale use like charging a vehicle are totally impractical.
In the real world, you can move electricity using a battery, or a power line.
Power lines aren't portable. Extension cords are, but are impractical over somewhere between 150 and 300 feet depending on the size of the wire in them.
Almost anything you would put at the end of a road would require electricity, so you will find that almost all roads have electrical lines near them. Not to mention, I see obvious sources of solar power in the picture, but gasoline has to be trucked in from thousands of miles away.
If something like a billboard was in the middle of nowhere, then solar is a great choice for that niche use. If you build a house in the middle of nowhere, you can get power without running a line to the house, including trucking in a fuel like natural gas.
A fuel cell is a form of battery.
It is a chemical reaction sort of like a battery, but doesn't result in discharge over time. Fuel cells are practical. Batteries are a dead end.
