We are pretty much off grid here. I supply my own water from well water and generate electricity as well as having a whole house generator, internet is satellite internet. Food we grow during the growing season which we blanche, dry off and freeze. Meat, I raise cattle and the missus has her chickens. I butcher one of the cows every year, half of which I trade for pork and lamb, on top of that we have plentiful game and fish around these parts.
I have two huge underground fuel tanks, one for oil and one for propane, electricity is supplied by two windmills. We also have a hand pump for water should the brown smelly stuff hit the fan.
It's a lot of work but I wouldn't have it any other way as I love living this life.
