> How do you pump fuel if the grid is down?
Gravity. Siphons. Manual pumps. Etc. Real complicated stuff known since figuratively Roman times.
I can power a couple of radios with far less than a full generator.
When sitting in a truck bay, there’s a shore line providing mains power to keep everything charged — we’re generally talking a 10-16A draw.
That’s easily met with a small generator, as opposed to the insane power draw a full EV battery would require.
Okay, work out the size of a generator needed to power one truck vs the dispatch offices. Now tell us how many generators you need.
You can have both at once. This is what happens with some trains, frequently happens in mining, and happens in some large industries. It is what occurs with hybrid electric vehicles.
The latest round of electric vehicles are getting 80km (50 miles) off the battery. That sort of thing is find for most of the service vehicle types you listed, and meets the requirements for greening a fleet and having alternative power options.
This is one of those statements that sounds reasonable when its you with your consumer-grade whatever, and has absolutely no relevance to large scale logistics and planning.
Fuel in ground tanks when the black out starts is...fuel in the ground tanks which is going to stay there because no amount of human labor is getting enough of it out to keep multiple trucks going.
