We live "off-grid" in rural NZ, apart from our internet, which I needed for my work. So we're not fully off-grid, I guess.
We run PV panels for our power, have rainwater collection and a worm tank septic system. We run two fridge/freezers, computers, TV, musical equipment, tools from the solar no worries. We raise lambs for meat and are getting our gardens started in the next year or two. There are a lot of power cuts where we are (just had a 45 hour power cut - we had all our lights on while our neighbours' houses were pitch black!) and it is wonderful to have the security of managing our own power. I wouldn't trade it for anything. The only crap thing is the amount of money / gas we use getting to and from our jobs in the city, but with FIRE that will change, too.
