'''Energy statistics''' refers to collecting, compiling, analyzing and disseminating data on commodities such as [[coal]], [[crude oil]], [[natural gas]], [[electricity]], or renewable energy sources ([[biomass]], [[geothermal power|geothermal]], [[wind power|wind]] or [[solar power|solar energy]]), when they are used for the energy they contain. [[Energy]] is the capability of some substances, resulting from their physico-chemical properties, to do [[Work (thermodynamics)|work]] or produce [[heat]]. Some energy commodities, called [[fuels]], release their [[energy content]] as heat when they [[combustion|burn]]. This heat could be used to run an [[Internal combustion engine|internal]] or [[external combustion engine]].

The need to have [[statistics]] on energy commodities became obvious during the [[1973 oil crisis]] that brought tenfold increase in [[petroleum prices]]. Before the crisis, to have accurate data on global energy supply and demand was not deemed critical. Another concern of energy statistics today is a huge gap in energy use between [[developed country|developed]] and [[developing country|developing]] countries. As the gap narrows (''see picture''), the pressure on energy supply increases tremendously.[[Image:Global energy consumption.jpg|thumb|right|525px|Global energy consumption per capita, 1950-2004]]

The data on energy and electricity come from three principal sources:
* [[Energy industry]]
* Other industries ("self-producers")
* Consumers
The flows of and trade in energy commodities are measured both in physical units (e.g., [[metric ton]]s), and, when [[Energy accounting|energy balances]] are calculated, in energy units (e.g., [[terajoule]]s or [[Ton of oil equivalent|tons of oil equivalent]]). What makes energy statistics specific and different from other fields of [[economic statistics]] is the fact that energy commodities undergo greater number of transformations (flows) than other commodities. In these transformations energy is conserved, as defined by and within the limitations of the [[First law of thermodynamics|first]] and [[second law of thermodynamics|second]] laws of thermodynamics.
