We just moved to a new hom with the intentions of getting off the grid, but we aren't there yet. I have city power, but it isn't neccesay, I have a battery back-up, inverter, and lots of windows. I don't really need power if it came down to it. The house would be bright during the day and dark at night. The Dryer runs off propane as well as the water heater and stove. I have a water well with an air pump running off a windmill. A big wood stove that heats the house quickly even in -35. There are about 5 lakes within walking distance.
I think living off the grid would mean never having to need anything from town. Maybe one day I will ge there, but it's expensive.I still have to go in to get groceries, although i could hunt more than I do, but I need some veggies that won't grow at my altitude and climate. I still need propane delivered once a year, and plan on putting in an oil furnace this year so I don't have to depend completely on wood. I would like to put in solar seeing as I have part of a system already with the batts and inverter, but that will have to come in time. All taht matters now is that I am better of in a power outage or loss of services then probably 95% of the people in North America.
