Is there a possibility of double counting in Energy Demand (Final Units)? When I conduct the calibration of the model results, which one, Energy Demand (Final Units) or Energy Demand (Primary Units), can be used for comparison with local statistical data? Thanks in advance for the kindly reply.

Energy demand (final units) shows levels of final energy consumption: the energy consumption you have modeled in the demand branches in your LEAP model. The values should be comparable to the section of an energy balance showing final energy consumption. If your model has sectors listed under your high-level demand branch then these will appear as rows in your Energy Balance report and they should be directly comparable to published energy statistics (assuming your model is working OK!)

As an example, look at the two screenshots below. One shows energy demand in final units in 2020 in a baseline scenario by sector and by fuel category. The other screenshot shows an energy balance for 2020. Notice how the bottom demand section of the energy balance matches the energy demand (final units) report.

Energy Demand (Primary Units) is a much more specialized report. It attempts to take the secondary energy consumption consumed under your Transformation branches and allocate it back to demand branches (adding it to the final energy consumption values). In that way it gives you a sense of the primary energy implications of activities listed under your demand branches. Please note that this report uses heuristic methods to make that allocation. These work well in most models but in models with highly complex Transformation sectors (e.g. those with coproducts, or feedback flows or those that use auxiliary fuels) these calculations can sometimes misallocate values. For this reason, I would use this particular result variable with great care.

I hope this helps,

Thank you for your response and providing an answer to my question. I think scenario comparison is good way to understand the issue, thank you again for your assistance.
