  As renewable sources of fuel, such as wood become scarce it is important for any society to make the transition to mass-produced fuels such as coal or paraffin, and then later shift to electricity or gas.

  He also made regular trips to Kilbeg Creamery for paraffin for his heater.
2. 1.2Chemistry

  Because kerosene belongs to the family of hydrocarbons called alkanes or paraffins, it is sometimes referred to as paraffin oil, in addition to the nicknames coal oil, lamp oil, and illuminating oil.

Origin

Mid 19th century: from German, from Latin parum 'little' + affinis 'related' (from its low reactivity).

This word first appeared in 1830 in German, coined by the chemist Karl Reichenbach from the Latin parum ‘little’ and affinis ‘related’ (also the source of affinity (Middle English)) because of its low chemical reactivity. It was in use in English within five years.
