Off-grid isn’t a state of mind. It isn’t about someone being out of touch, about a place that is hard to get to, or about a weekend spent offline. Off-grid is the property of a building (generally a home but sometimes even a whole town) that is disconnected from the electricity and the natural gas grid . Off-grid buildings are therefore self-sufficient for light, power, and heat. But as it goes, people who live in off-grid homes also tend to be independent for procuring other vital resources, such as water and food.
