Glossary:Tonnes of oil equivalent (toe)
Tonne(s) of oil equivalent, abbreviated as toe, is a normalized unit of energy. By convention it is equivalent to the approximate amount of energy that can be extracted from one tonne of crude oil. It is a standardized unit, assigned a net calorific value of 41 868 kilojoules/kg and may be used to compare the energy from different sources.
Other energy carriers can be converted into tonnes of oil equivalent (toe) using the following conversion factors:
- 1 t diesel = 1,01 toe
- 1 m3 diesel = 0,98 toe
- 1 t petrol = 1,05 toe
- 1 m3 petrol = 0,86 toe
- 1 t biodiesel = 0,86 toe
- 1 m3 biodiesel = 0,78 toe
- 1 t bioethanol = 0,64 toe
- 1 m3 bioethanol = 0,51 toe
