Some parts of the world have no infrastructure for electricity or water. The people that live there need to be independent and create their own energy.
Here are some photos of what it is like of the grid:

These campers are having fun off grid.
A tiny house on wheels with self contained fresh water and solar.
Living in a rural area is a lifestyle choice.
If you spend 1 night in a camper van you will know what it is like. There is no cell service way out here, no water, no sewer, no power outlets.
In places like India, Scotland, and Papua New Guinea there are many people living off grid due to being only choice.
A large solar array can power small appliances and lights.
The sun provides plenty of clean power.
