We had this discussion the last time &quot;off-grid&quot; came up.<p>Some take it&#x27;s meaning more literally, with grid meaning pipes or wires delivering services to your home.<p>So gas being piped into your generator would be on-grid, if it gets trucked in then that&#x27;s off-grid. Electricity via wires is on-grid, electricity via a factory built solar cell or windmill is off-grid.<p>Others have a more poetic definition of &quot;off-grid&quot; as &quot;self-sufficency&quot; though it&#x27;s hard to see where that ends, as there&#x27;s no clear dividing line, even a child born in a remote rainforest tribe with no contact with the world will end up using tools and techniques passed on by local culture.
