Barrel of Oil Equivalent (boe)


boe (“barrels of oil equivalent”) is a unit of energy; a representation of how much there is in one barrel (=42 US gallons or ~159 litres) of crude oil. It’s equivalent to ~1700 kWh, even though in reality oil comes in different grades, so a barrel volume of different grades will contain different energy amounts. It’s a unit that’s most likely to be seen in charts or data presenting country-scale energy mix information, where a variety of energy sources and types are converted to this one common unit.
