And what if natural gas stops being delivered?
I know a guy whose grandfather dug a gas well on their land back in the early 1950’s for a couple hundred bucks. No enviro-impact statements, no EPA - just drilled the damn well. He is supplying gas to his own home and a few vacation cabins he owns on a nearby lake.
I told him I’m going to his place when SHTF. He joked and said - we’ll see if I let you in....
That is extremely unlikely. Natural gas lines are subject to decay through water intrusion if unpressurized, so it would have to be a very extreme and long-lasting situation for the gas to be turned off. Moreover, if you want a generator to be working 24/7 for more than a day or so, there is no way you can store enough gasoline, diesel, or propane on site. Nor do you want to be managing that headache. NG is the way to go.
Here in Houston our natural gas is delivered via underground pipeline. It never goes out even when we get hit by hurricanes.
