In our area, when a storm hit, the roads washed out, so the generators ran out of propane. Then the local propane companies ran out of delivery truck capacity because of the demand surge. Finally, the regional distributors ran out of propane.
Our solar panels kept the fridge running, but we were heating the house with a wood stove (it was very cloudy, so we were getting maybe an hour of sun a day). If we had bidirectional house charging, we could have had warm showers + used the heat pump: We would have been able to fast-charge the car at 100-200kw in town. The house can limp through 20-30 hours on ~ 25kwh, so the charger would charge the house at a few days per hour, including losses from driving to and from town + round tripping through the battery, and also running the house heat pump.
None of the other people around here stayed online. Some propane-dependent people had no electricity for > 2 weeks (with rationing, they managed to keep their generators online for about a week, and PG&E took three weeks to fix their lines).
This was in the outskirts of Silicon Valley, so better-than-puerto-rico infrastructure, but only just.
This is a total failure/incompetence of multiple utility institutions that we all pay for and depend on. An electric company that does not have the capacity to respond quickly to natural disasters and propane delivery infrastructure that doesn't have the reserves to weather such an event. Even a day without electricity should be unacceptable in a modern, functional society. How do we tolerate 2 weeks? I bet the CEOs of these companies are not going without electricity for 2 weeks.
We are far away from, but slowly approaching, Mad Max levels of institutional failure, and everyone seems to treat it as normal and unavoidable.
