In global energy model, the assessment of the industrial sector is often simplified, because of the difficulty in assessing several industries, in detail, for many countries and regions of the world, where the detailed information needed are not easily available. Then a simplified approach for all 18 regions was used for the current model, considering only one industrial sector.
To estimate the energy demand for every region and the energy sources that provide this demand, the International Energy Agency (IEA) main energy datasets were used. Besides it is important to assess the energy services that are consuming energy. In industrial facilities the most common energy services are related to heating (direct or indirect) and drive of machineries, such as engines and turbines. The energy services modelled are: Heat, meaning direct heating; Steam, either for indirect heating or steam-driven engines; HVAC, or Heating, Ventilation and Air Conditioning of internal areas; Light; Motor, or the drive for electric motors; and other services.
Besides energy consumption, the industrial sector also presents a consumption of typically energy sources as non-energy inputs. This includes naphtha, from refineries, natural gas and even coal. Typically, these products are used as feedstock in industry processes, such as ammonia and petrochemical production. The non-energy consumption does not result in energy-related emissions, but it is an important part of the total consumption of energy products and they are also considered in this model.
