Well, I am not in Florida, but in Maryland where we get a drastic change of seasons, sometimes in the same day, here is what I have found out regarding living off the grid. First, I wouldn't want to.
I have a house that is paid in full on 3 acres. I have access to a natural clean spring and a creek with small fish in it. I have done extremely minor "prepping" since I was about 8 and we had to run, duck and cover in case of a nuclear blast. Yeah, that will work really well...not.
Anyway, since I do not like the idea of being "trapped" in the house in one of those winters where we have a 30" snow, yeah, that happens every decade or so, or an ice storm that's bad, which is more frequent, or tornadic winds, yeah, that's every year within a few miles or here or such, I have been negligent this year in getting ANYTHING ready except a flashlight and batteries.
Now that I'm an old toad I finally did some upgrades. I first went from a minivan to AWD Chevy Equinox. It likes the snow. It just happened to be one of the more reasonable vehicles out there when I went to look for a car 5 years ago this week!
So this year I watched way too many youtube videos and made some adjustments. Got some dried and canned food, I don't keep a lot here anyway so this was a big deal. Got a cot and sleeping bag in case the power went out for a week or more, that way I can sleep closer to my emergency heat source. It has done that in recent memory, fortunately it was in the month of September.
I have a whole house generator but it's only good for so long as you have fuel to run it. So I got a Mr. Heater portable heater (under $100) and some propane for it. I have enough to keep from freezing for at least a week. I have a kerosene heater but the fumes bother me these days. The propane heater is 100% clean. I tested it for the first time yesterday and it's a winner!
So...water, food, heat for a few weeks.
Add in a 100 watt solar panel system to recharge a humongous deep cycle battery and I have 10 years of light or fan or even computer or 12 volt refrigerator.
So, if it hits the fan? Living off the grid is not very workable. There are several things that will take a prepping plans to ruin almost immediately.
A fire. A big storm throwing a tree into your house. Crazies coming to take what you have, and as one guy pointed out, they have relatives who will come after they are gone. An illness. An injury. Any preexisting medical condition.
Chickens are very tasty, don't tell my elderly hens that. Plus you have to breed them as they don't lay eggs indefinitely. Which means a rooster who will let the entire world know where he and you are.
So...forget it long term. Best thing to plan for is a few week emergency situation. Like a hurricane in Florida. Or an ice storm in Maryland.



A couple toys I got for the 2 week emergency. They come every 20 years or so. The one week emergency about once in 10 years. The one day no power, at least twice a year, not including the times the power goes out for 4-8 hours, which is about 10 times a year, at a minimum.
