2 Likes Total Energy Demand is given in GJ, but almost all activities and fuel types do not have GJ as their unit.
1 Like You can input data and view results in any unit. In LEAP's Results view, just click on the unit button on the Y axis to select other units. You can even define your own units using the General: Units screen. All calculations use double precision floating point values, and conversion factors are specified with a lot of precision (TBH I am not sure exactly how many significant digits) so the results you see will be very precise and (if you build a good model) accurate.
The underlying principle is the application of energy conversion factors to express different forms of energy in a common unit (Gigajoules), enabling consistent accounting and comparison within the energy system.
