The power doesn’t go out at my house that often, and when it does, it’s typically not for very long (one notable exception being Thanksgiving 2014.) With propane-powered stoves for both cooking and heating, I’m perfectly capable of keeping myself fed and warm(ish). The one mild pain in the butt is the on-demand hot water. It’s propane-powered, but requires electricity to start up. And with no reservoir tank to hold heated water, my water is icy cold as soon as the power goes out. It’s also going to be nice to keep my groceries from spoiling.
This kind of stuff really does require a professional. Now that this is done, I need to shop for a portable generator.
