Dear Taylor,
I have completed my demand analysis by constructing reference and mitigation scenarios for a study to analyze the energy and emissions savings (by the introduction of efficient appliances in slum households in Asia and Africa) and cost of achieving mitigation scenario. So far, I have calculated the energy savings as a difference between the two scenarios. I am still trying to figure out how to calculate CO2 emission by incorporating emission factor into the energy demands in these two scenarios. I think my precise problem is that I do not know how to assign emission factor values to the end-use demands. In this regards my questions are: a) Do I need to complete transformation and resource module in order to be able to calculate emission savings? Or Can I calculate emission reduction for only demand module? and Where can I get the lead for this, any training material…? Actually, I only intend to do demand analysis; the rest I can’t due to data unavailability (well, as mentioned earlier my problem is that I do not know how to assign emission factor values to the end-use demands) b)Can I also complete cost calculation for only demand module?
Thanks for your patience in answering my questions.
Regards, Rajesh

Hi Rajesh,

I'll start by pointing you to some of our help materials, which will help you to understand how emissions are attached to fuel consumption in LEAP. First have a look at our basic training materials, specifically Section 1.5:

http://www.energycommunity.org/default.asp?action=42

There is also a good help page on the topic, which you can find here:

http://www.energycommunity.org/WebHelpPro/Demand/Environmental_Analysis.htm

To answer your specific questions, you do not need to have a completed Transformation branch before you can add emissions: you can add Environmental Loadings at any step of the way, by switching on 'Energy Sector Environmental Loadings' under Basic Parameters:Scope. But be advised that unless you add emissions to your transformation processes as well, your total calculated emissions savings will of course not reflect any supply-side emissions reductions (this is an obvious point, but I want to make it clear!).

To add emissions, navigate to the Environmental Loading tab of your Demand technologies and select either the green plus sign (add a single emission factor) or the TED button (link to LEAP's Technology and Environmental database).

You can add Demand Costs to your model, by ensuring that Costs are enabled in Basic Parameters:Scope. The following help page will guide you through the different demand cost methodologies available in LEAP:

http://www.energycommunity.org/WebHelpPro/Demand/Demand_Cost_Analysis.htm

How you define your demand costs is up to you - you may choose to add a demand cost that already incorporates the cost of producing each fuel (for example, you could add the cost of electricity to each technology that consumes electricity), in which case you can do a complete cost analysis using only the Demand branches.

Hope this helps!

Dear Taylor,
Thanks for answering my previous query. I have two questions and seek your kind help:

i) Can one account for variable fuel costs (resulting from changing fuel intensity) in Activity Cost method? Or is Cost of Saved Energy (CSE) method ONLY suitable for this purpose?
ii) In the lighting demand branch I have mixed Kerosene lighting with lighting sources that use electricity (CFLs and incandescent). Can I use Gigajoule unit to represent kerosene energy demand and kWh for CFLs and incandescent lamps? It seems LEAP only lets to represent demand in one unit (either gigajoule or kWh) for all the devices within a branch (I guess to make it easier to compare between them). In that case do I need to separate kerosene lighting with electric lighting? I have 50 countries to analyze hence I’m trying to simplify the analysis as much as possible.

Thanks for considering to answer these.
Best regards,
Rajesh

Hi Mukesh,

1) The Activity Cost method is not sensitive to the amount of fuel consumed by a demand technology - it depends only on the activity. Therefore it could not be used to represent costs savings brought about by reducing the energy intensity of a demand technology.

2) LEAP has no problem with different units of energy for adjacent branches in your demand tree. Therefore I'm not sure what you mean when you say that "LEAP only lets [you] represent demand in one unit", but if you do encounter an issue while trying to do this, please let me know what you're doing when the problem appears!

Best,

Taylor
