U.S. heat content of liquefied petroleum gases 1960-2016
The statistic represents the U.S. heat content of liquefied petroleum gases (LPG) between 1960 and 2016. According to the source, heat content is defined as the amount of heat energy available to be released by the transformation or use of a specified physical unit of an energy form (e.g. a barrel of oil or a cubic foot of natural gas). The heat content of LPG was approximately 3.17 quadrillion British thermal units in 2014.
