It's not that easy to make your own power and have it maintained to a sufficient degree.

And regarding the offgrid...i think you hit the nail on the head: they can't bring themselves to cut ties with the grid. In actual fact the grid is built into the city and so they can't actually cut your utilities; they just capitalise on the fact they can put their meters into your home which they charge you for...but not the thing they propose to supply (which they don't supply, as it's all part of the grid).

Going off grid is not easy man, i know of one individual here by the name of Cahlen the Wizard, who upvoted on my video here. Check his channel out.
