If you're _really_ off-grid, it probably is. A hermit living off the land in a wooden shack they make with hand tools and solar panels on top, using a mountain bike to get around, probably doesn't have much of a carbon footprint.

The main issue is when you're still basically on-grid but a long ways away from everything, and depend on a car.

Though I am probably biased because I just bought a bit of land and hope to grow my own food on it. Pretty easy bike ride from the train station, though, and I work 100% remote.
