You are still burning vapour not liquid with a propane appliance. When you draw off the vapour and burn it, the liquid in the tank boils to create more vapour.
Propane is a cleaner burning fuel emitting fewer greenhouse gasses. Propane is not a greenhouse gas in its natural state. Propane has higher octane rating reducing the tendency of knocking, evident in some petroleum/diesel engines. Propane is much cheaper to purchase than gasoline or diesel. Propane is nontoxic and not detrimental to soil or water if accidentally spilled.
