think of natural gas as a secondary "electrical grid"
Discussion
Can you explain this more?
here is a comparison table

for every BTU/lb of NatGas you get equivalents of energy output. that is often heat but could be electricity and the output flowing in a pipe is essentially an electrical grid independent of the wires in your neighborhood
Not every neighborhood has natural gas infrastructure though.
I think I'm catching the thought though. Natural gas infrastructure is a means of distributing energy independent of the electrical grid.
It's mostly used for heat, but could in theory be converted to electricity.
