Decentralized power is the future.

The problem with your scenario is that gasoline/diesel stations cannot be economically decentralized, and electrical power can be.

Your final example will of course hold true, but for an ever-decreasing number of people. Many with a dedicated parking spot will eventually charge their cars via induction (like our phones now) so we (almost) can't forget to "fill up."

In my condo garage, I'm the only flat with a wall shared by the garage. I already have 400v wiring from my flat to a cellar across the garage. I can easily meter that line and sell electricity to the other seven people who park there. This would of course not be possible with fossil fuels. Multiply that example by 1000 or 10000 for the other garages in just my city of nearly 2 million.

Eventually, solar systems and capacitors will be cheap and efficient enough that I can charge my car and my neighbors' "for free" during sunny months (which there are ever more of). Again, this would of course not be possible with fossil fuels. And again, multiply that example by 1000 or 10000 just for my city.

I live in a city with winter and not a huge amount of sun. I can't imagine that in 50 years there will be much of a power utility in Arizona.
