Sounds like de-centralized power generation, maximizing remote work, and delivery vehicles powered by electricity and hydrogen is the way forward.

Why de-centralized power generation? I was under the impression that the electrical distribution system is very efficient in the US and economies of scale make large scale renewables much cheaper.

In the US at least, transmission loss seems to be on order of 5% of total energy distributed. Source: https://www.eia.gov/tools/faqs/faq.php?id=105&t=3#:~:text=Th....

The economies of scale seem to be much larger. For example, utility scale solar seems to be about half the unit cost compared to residential and commercial solar: https://www.nrel.gov/analysis/solar-installed-system-cost.ht...
