    Hi,


    I am conducting a study on final energy demand at an aggregate level and the associated emissions.I will need to specify the mathematical expressions of the these variables. If I find the equations of the final energy demand in the users guide, I couldn't find those of the energy consumption for transformations or for total emissions. Would it be possible that you have a look to the below equations and let me know if they look good? thanks and best.

    Hi Nadia,

    Sorry for the delayed response. Just to clarify - you are writing documentation for a particular model which you've developed in LEAP, is that correct? I ask because some of the statements you've made, while correct, are not very general (i.e. they exclude some of the methodologies available within LEAP), even they may be sufficient to explain the methods used in your model. Anyways, two comments:

    1. More simply, the energy output from a transformation process is equal to the energy contained in its feedstock (inputs) multiplied by the process efficiency. Equation (2) is unconventional, but correct if ET is taken to mean the net energy loss for a transformation process - i.e. energetic inputs minus outputs.
    2. I'm not sure what AL is in Equation (3). Is it defined earlier as TA? If so, then yes - total annual emissions of any pollutant can be calculated per unit of energy consumed, multiplying the energy consumption by the mass of pollutant emitted per unit of energy consumed.
    Otherwise, I don't see anything that's wrong. Good luck,

    Taylor
