Bonjour cher communauté, je suis nouveau dans julia et j’aimerais avoir un code gams sur la modélisation du secteur de l’énergie afin de faciliter la compréhension du code julia.  
Merci

Hi @omar_diouf,  
Welcome to the Julia forum! We usually post in English here.  
I’m not sure I understand why you are asking here for a GAMS code? Do you already have a Julia code to compare with?

Merci pour votre réponse, oui j’ai téléchargé sur Github le code Julia. Vu que je travaillais sur GAMS et c’est la première fois que j’ouvre Julia. Il se serait intéressant de comparer les deux bien vrai j’arrive à comprendre les équations dans Julia. Merci

I think JuMP.jl is the closest to GAMS modelling but not sure, I also see [GitHub - GAMS-dev/gams.jl: A MathOptInterface Optimizer to solve JuMP models using GAMS](https://github.com/GAMS-dev/gams.jl) but its based on JuMP.jl and I didn’t have a look. Note that this won’t help you learn julia that much since those library use really high level symbolic utilities but its a good start.  
Also, yes, post in english if possible even though they are french people (like me) here, if someone else one day comes from GAMS and wants to follow this thread it’s always best to have it in english

If you want the Julia port of the latest Nordhaus’ DICE 2023 model (the official is in GAMS):

> **[GitHub - sylvaticus/DICEModel.jl: Julia/JuMP port of the Nordhaus' DICE (Dynamic...](https://github.com/sylvaticus/DICEModel.jl)**
>
> Julia/JuMP port of the Nordhaus' DICE (Dynamic Integrated Climate-Economy model) model.

This can be used to either compute the optimal carbon tax or to estimate the effect of various carbon policies.
