Thank you, Madam Chair. Energy efficiency, as I said, it is a priority when renovating and also administering our units. I can look at that, the wood-pellet boiler system, but then I need to keep in mind that, if we are able to provide this service, then which region would be able to be adequately providing the material. I would like to look at that and justify which regions this would probably work more adequately in. Thank you, Madam Chair.
