Venezuela (Bolivarian Republic of) is being the top country by heat content in the world. As of 2012, heat content in Venezuela (Bolivarian Republic of) was 27,592 thousand btu per short ton. The top 5 countries also includes Peru, Chile, Ireland, and Norway.
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 ton of coal, a barrel of oil, a kilowatt-hour of electricity, a cubic foot of natural gas, or a pound of steam). The amount of heat energy is commonly expressed in British thermal units (Btu). Note: heat content of combustible energy forms can be expressed in terms of either gross heat content (higher or upper heating value) or net heat content (lower heating value), depending upon whether or not the available heat energy includes or excludes the energy used to vaporize water (contained in the original energy form or created during the combustion process). The Energy Information Administration typically uses gross heat content values.
