If it comes to Mad Max we're all stuffed. I'm looking at it like a phase that has to pass. Or until the big guy upstairs relieves me and has me quit my post.
Look into a windmill. They are expensive but you will no longer have to be on the grid and have to pay or depend on others for electricity.
You can probably get set up in a used trailer pretty cheap.
Admire your spirit. Be sure to check into cost of getting electric, water, and septic in. You might think about getting a house trailer on your property and not plan on a tent for more than a week. Being out in the woods you need to think of bears and such. You would be safer in a trailer until you can get your home built. :)
