In the hierarchy of moving things around, from difficult to easy:
- natural gas (building a pipeline)
- electricity (generation, transformers, high voltage lines, etc.)
- bits (copper, fiber, microwave, cellular, satellite all are viable for low bandwidth operation)
It's orders of magnitude in terms of cost difference.
The issue with superchargers is mostly that these places are in the middle of nowhere--nobody is going to be driving their Tesla across the Permian.
