You're a lawyer. Check out the legality of providing not just your own power (using solar or a backyard nuke), but on-selling capacity to your neighbours. I'd think the state will quite quickly claim that you're usurping its power (thanks, I'm here every Tuesday, when I'm sober). It will present you with a myriad licences and regulations and restrictions. In short, I reckon the barriers to doing this, if it's at all possible, would be very high.
