How do you think those windmill parts and solar panels get from the manufacturers to the end users?

I personally don’t see solar and wind able to provide enough energy to electrify an entire nation’s fleet of freight haulers. Nuclear, maybe — assuming they build a bunch of little plants so a truck can “refuel” in the middle Wyoming away from large populations.

Maybe Wyoming isn’t the best example as it’s always windy there but the point stands.
