I don’t have any personal experience, but that sounds like a plan to me. I do really like propane, and I recently got a small generator that runs either gas or propane. Just need to change out the spark plug so it burns hotter or something (for propane). In fact, some people just use propane in their generators because it runs cleaner.
Idk, frankly I think all fuel is a non-issue, because in an emergency all these things run on money, money, lots of money. Fuel today, gone tomorrow. 20# propane tank? Gone. 8-gal gas? Gone. Hopefully it’s enough to run your appliances & get you by until utilities are restored.
In an extended power outage or grid down type situation, generators are great to have but you’ll be limited by your ability to obtain fuel. And the money to run it. A generator will be loud & could attract unwanted attention from beggars, looters/thieves. The best investments you can make right now is increasing your efficiency ((insulation)), reducing your energy needs, & investing in things that can help you in a grid-down situation.
Frezik is right, there are plenty of small wind turbines. As I alluded to, the tech naturally involves moving parts & has been prone to breakdowns. They’re getting better all the time, but the small ones don’t produce heaps of power. The big ones do; there is a bigger residential one in my community & it outperforms the solar panels 8:1. It also broke down in the first year of operation, and a crane had to come in & take the turbine down, to be shipped to TX for (thankfully under warranty) repairs.
I like to see everything getting better, I think I feel more comfortable with solar panels & reducing needs, increasing insulation.
I can’t Google what I remember seeing, but they’re working on very efficient & tough ones that just spin in place. Mounted to the roof of your house. It’s kind of like that vid posted below, but not, the fins looked like 2 ribbons.
