Subject: questions, Posted: 7/18/2005 Viewed: 1559 times | Dear Prof Heaps, Firstly, thank you for your help to change my mail address. I inform you that finally I could to inscribe to leap site web and could to install the software. Secondly, I inform you that finally I could inscribe in the “LEAP SITE” and I have successfully install the software. When, I was trying to use this very interesting software but I met many difficulties. Now , I have just obtained my M.A. and am applying for a PhD. I am particularly interested in the energy and environment research area . I expect to develop during my thesis work a statistical model to compare the energy variables with the environment variables. Specially, I am interesting to “ Economic impact of reduction gazes emissions by energy sector ” . But in first step, I need to estimate previous CO2 emissions of transport sector, oil and gas production sector, oil refining sector. Unfortunately, I didn’t find how I must proceed. I have red the help but without any succes. I summarize my main idea of my study in the following questions : - Did the LEAP allow previous emissions estimation by sector mentioned above ? - if it allows, what are the determinants variables and is it necessary to have the historical data of these variables or the value of one period (example : year ..) is sufficient for each variable (basis year). - Did the LEAP allow to estimate costs of emissions reductions. Many thanks for your help Mr Heaps. Best regards. Nassima HAMIDOUCHE |

Subject: RE: questions, Posted: 7/19/2005 Viewed: 1555 times | Dear Nassima, Sorry it has taken me a while to reply, and sorry about the difficulties. Question>>> Did the LEAP allow previous emissions estimation by sector mentioned above ? Yes, LEAP is normally used to specify one "base year" of data (in Current Accounts) plus various alternative scenarios that project a system forward after the base year. However, you can also specify an earlier base year and then use the various time series functions (e.g. interp) to enter historical data in Current Accounts. For example, assume you have historical data from 1980..2000, you could enter: Interp(1980, x, 1985, y, 2000, z) The trick then is to have the various forward-looking scenarios start diverging from the historical data only after the last historical year. In a scenario, you can use a function like this to have a growth rate applied only after some specified year: GrowthFrom(2000, 3%) In any year before 2000, the scenario will use the historic values you entered in Current Accounts Question>>> if it allows, what are the determinants variables and is it necessary to have the historical data of these variables or the value of one period (example : year ..) is sufficient for each variable (basis year). Sorry I don't understand this question. Could you try and rephrase it? Question>>> Did the LEAP allow to estimate costs of emissions reductions? Yes - LEAP allows you to calculate an overall cost-benefit analysis of one scenario versus another. You can include capital, operating and maintenance, fuel, externality and administration costs. At the request of other users, I am going to improve the documentation of costs in the help file. I am also going to update the training exercises to better cover costing. Regards, Charlie P.S. Unfortunately, I am not a professor :( |

Subject: RE: questions, Posted: 8/2/2005 Viewed: 1549 times | hello charlie, thank you very much for your answer. I start to see more clearly about the leap. As I am going on vacation for few weeks, begening next september,I will use it more often, if I will met some problems I hope you will be helpful to me. Regards.
