I did some numbers on the F150 Lightning
So based on my local Electricity price you can do about 12 miles for a dollar. The gas equivalent is maybe 5, one of the advantages is you lose no power with altitude and there is a lot of up and downs and you can regenerate on the down.
I think a game changer and it is coming is to tie everything in with the house system.
Now if you use a supercharger the numbers change and it is sort of similar to gas. Well it can be the local one here is 45c a KW, now no wonder it is not used.
I did not look at diesel because they are in a different price bracket.
Now I know someone in Construction who has a Rivian and you do not need to worry about power at a site, you can run all your tools off the truck.
I also know a lot of people with off grid systems, add a few panels and charge your vehicle, so free ish.
Places like CA with blackouts and variable charging makes even more sense, fill up the vehicle when it is cheap and draw back down when it is expensive.
