Some of the posts I’ve seen elsewhere suggest:
People running generators had limited fuel and with the extensive road damage, may be unable to acquire more. One guy posted on Reddit asking for help repairing the carburetor on this generator because it had clogged and he had no way to acquire a replacement.
One guy who had rooftop solar and a whole home battery appeared to be in the best position to ride out the extended outage until service could be restored. He also had an EV, so he could charge his EV from his home solar system.
This has certainly given me food for thought.  I live in SE Michigan and our area is notorious for storm related power outages that last 1-3 days. I have a portable generator. These storm related outages are usually fairly isolated and acquiring gasoline is relatively easy. I do not have a hookup (yet) that allows me to tie my generator into my breaker panel so that I can power my AC unit, etc. I run a series of extension cords to critical appliances (the refrigerator, the cable modem and laptop, fans, lights, etc).
Hearing about the situation in Western NC has me thinking I’m probably more prepared than some, but still not as prepared as I could be. Maybe I should get a Ham Technician’s license and a couple handheld HAM radios. Perhaps I should get some portable Solar panels and a larger battery based power station (Jackery, Anker SOLIX, etc)
My heart goes out to all the people affected by Helene. I’ve been rock climbing in Pisgah Forest just south of Asheville with a local guiding company (Fox Mountain Guides) on two separate occasions, and camped at the Davidson River campground in the National Forest while there.
