I challenge you to read this article by Rob Rhinehart and not have your mind spinning with new ideas and possibilities.
Living off the grid (in more ways than one) doesn't have to be about strange men re-locating to the wilds in preparation for a global disaster that isn't coming. In this case it can be a considered and planned way of reducing your environmental footprint, improving your lifestyle and benefiting your health.
Here in New Zealand the volume of 'green' power available on the grid makes some of the arguments spurious. However the rest is mostly good. Well apart from the Soylent diet, that sounds a bit challenging to me. And custom-made clothing in China, surely that runs counter to everything else espoused here?
Well worth a read though.
