1914 Views Hi,
I’ve finished chapter 1.3.2. During the process, there are 3 problems puzzled me:
First, I’ve built the tree by using“add” button, however, I can’t add “environmental loading factor”, such as “sulfur dioxide” and so on to the tree. Is it necessary in Exercise 1? How can I do it?
Second, I filled “ Final Energy Intensity” in the “Expression” after the finished tree. When I chose the “Fuel”, the “Branch” and the fuel in the tree were also changed. Therefore, I need to fill it again. What a waste of time!
Third, the conent of “cooking” in the “Electrified” and the “Non Electrified” of Rural of Freedonia are the same. Is it right? I think they should belong to the “Non Electrified”.
Waiting for your help and Thank you very much!

1908 Views Hi Wang,
Thank you for your questions. Let me respond to each one and see if we can help you continue on with the exercises.
1. The "Environmental Loading" factor is a variable (not a branch) where you add emission factors and other environmental loadings. This variable will only be visible if you are at a technology branch (within a demand sector) or fuel branch (within a transformation sector).
Under the demand branch, the technology branches are typically represented by grey gear icons (this represents an activity level analysis, which is what we use in Freedonia). If you select a technology branch on the tree, the "Environmental Loading" branch should appear within the list of variables to the right. If not, you should check your Basic Parameters (to get here use the top toolbar or go to the General: Basic Parameters menu option) and ensure that on the "Scope" tab the "Energy Sector Environmental Loadings" option is checked ON.
2. I'm not sure I understand you here. When you create a technology demand branch you select a name and a fuel. Then you may edit the expression associated with that branch in the right part of the screen on the Final Energy Intensity variable tab. There you have the option to change the fuel at the associated branch, but it will do just that - change the fuel. You should not edit the Fuel column unless you want to change the fuel at that level, you do not need to change it there otherwise.
3. You should have cooking for both electrified and non-electrified for rural areas. You want to indicate that there is the same distribution of cooking stoves among rural households, regardless of whether they are connected to the electric grid or not. This means that even electrified rural households do not use electric stoves.
Best,
Tory

1875 Views Hi, thank you for your reply and question 1 and 3 have been solved.
However, question 2 is still here. Here is an example:
Urban--Electrified--Refrigeration--Existing, "fuel" column is "Electric" at first, if I change it to "Electricity", the "Branch" column also changes to "Electricity" automatically.
Can you understand me now? I've tried a lot and failed.

1874 Views Hi Wang,
You should not be able to choose "Electric" as a fuel in LEAP - only "Electricity" in the standard English version of LEAP. Have you created new fuel in LEAP or are you using LEAP in a different language?
In short, you do not need to change the type of fuel in the Fuel column. Simply create technology branches and select the appropriate fuel and then you do not need to edit the Fuel column.
Best,
Tory
