WHY DON'T WE HAVE AUTO GAS AT GAS STATIONS HERE LIKE THEY DO IN AUSTRALIA???

[Pete Masterson]

Yes, I was confused by the "autogas" thing. I thought it was CNG. However most of the points still apply, although LPG is slightly heavier per gallon. 

Natural gas is primarily methane (CH4) (with small amounts of a panoply of more complex gases -- butane, propane, etc.) while LPG is a mixture of various gases with the major component being either (or both) butane (C4H10) or/and propane (C3H8). Natural gas, being primarily methane, is considered a very clean fossil fuel due to the small carbon content (1 atom for every 4 hydrogen) as it produces the least CO2 per unit of weight of any in this class of fossil fuel.

(evidently called Autogas in

Australia and butane/propane  in the US) are not really the same thing.
