there are places that don't inspect residential homes. i know a bunch of folks who aren't connected to the grid. don't know for sure if they were inspected, or if it's req'd. i don't care. one guy has solar and gas. (propane) and solar with storage batteries. runs his home quite well, in upstate ny. when the sun don't shine, the gas geny runs. yeah, you have to plan for "wash days" etc, but gas fridge, running water, it's all possible. they use electric and gas lights. wood heat and gas heat. anything is possible if one is willing to think "outside the box" we've all been so darned conditioned to. when i was growing up the only electric we used was for lights and outlets. my dad gutted a gas fired water heater and we built a brick fire box under it, and it worked fine. we heated and cooked on wood. all year. i'd do it again in minute. it kept the electric copmpany out of his pocket, gave me good times with him in the woods learning how to work and be independant of "the system" to an extent. solar will work, you don't need the grid. gas will work, wood will work, diesel engines were originally designed to run on vegetable oil. it only after the fuel companies got hold of the designs , and rudolf diesel killed, were people sold a "bill of goods" that had then believe otherwise. if you want to be real creative you can generate fuel from chicken poop. water power, all electric beagn with a simple water wheel of some sort, and generator.
