I have just started researching this topic now.
If the grid goes down temporarily, NG or propane is awesome.
If the GRID goes down, NG is gone and propane will eventually run out.
I'm going solar.
Don't care about central AC or heat, but local intermittent heat and well pump are priorities.
8kw solar systems can run my well pump and cost around $5k.
I have a few smaller systems and like the technology.
Even in total grid failure solar should be OK.
