Saying pete is renewable is like saying aquifers are renewable. You're not wrong, but how much can you extract renewably? Any amount extracted above that is like burning coal for CO2 purposes.
Also, pete is incredibly dirty in terms of air quality.
"FM is no more complicated than AM to transmit and receive."
FM is simple compared to WiFi6, but its an order more complicated than AM. An AM receiver only needs a diode and a coil of wire. The diode can be a rusty blade.
I dont think you can make an FM receiver without a transistor (which for me, as a former solid state guy is an order of magnitude more complicated than a diode)
