Propane is still very commonly used here in US. Mostly for backyard grills, but many use them for camping. They can power all sorts of appliances. Some people who live in rural areas use them as their main source of heating and sometimes electrical power for their homes. They have exterior tanks of propane 500-1000 gallons. Also not uncommon in rural Canada, Mexico. Not a cornerstone industry for most places, though but still very active.
