Propane and natural gas — allowed in most communities. Why? Autonomous. Tank on farm. Not grid-connected.
What Runs on Gas
Refrigerator (gas, absorption type — no compressor, quiet). Stove (like regular, just gas from tank). Washing machine (gas motor — yes, exists). Lighting (gas lamps — brighter than kerosene, but debated: 'too much like electricity').
Cost
Gas fridge: $1,500-3,000 (electric: $800). More expensive? Yes. But: no electricity bill. Over 10 years — cheaper.
