Its already been proven for yrs with the tiny house examples
Once the solar panel is put in place, u may pay for propane once a month, some type of insignificant camper lot fee, rain water sustainability, etc
Ur left paying for basic maintenance of any standard living qtrs
Per month
rent zero or 50$
Water maybe 10$
Propane 10-20$
Electricity virtually zero maybe 50$ per month savings for maintenance
This isnt even considering electic cars which would eliminate fuel cost and focus on battery efficiency
U can already take a couple heavy duty car batteries and a converter to supply massive energy
