World energy consumption is the total energy used by the entire human civilization. Typically measured per year, it involves all energy harnessed from every energy source applied towards humanity's endeavours across every single industrial and technological sector, across every country. It does not include energy from food, and the extent to which direct biomass burning has been accounted for is poorly documented. Being the power source metric of civilization, World Energy Consumption has deep implications for humanity's socio-economic-political sphere.
Institutions such as the International Energy Agency (IEA), the U.S. Energy Information Administration (EIA), and the European Environment Agency (EEA) record and publish energy data periodically. Improved data and understanding of World Energy Consumption may reveal systemic trends and patterns, which could help frame current energy issues and encourage movement towards collectively useful solutions.
Closely related to energy consumption is the concept of total primary energy supply (TPES), which - on a global level - is the sum of energy production minus storage changes. Since changes of energy storage over the year are minor, TPES values can be used as an estimator for energy consumption. However, TPES ignores conversion efficiency, overstating forms of energy with poor conversion efficiency (e.g. coal, gas and nuclear) and understating forms already accounted for in converted forms (e.g. photovoltaic or hydroelectricity). The IEA estimates that, in 2013, total primary energy supply (TPES) was 1.575 × 1017 Wh (= 157.5 PWh, 157,500 TWh, 5.67 × 1020 joules, or 13,541 Mtoe) or about 18 TW-year.
