== Energy services demand == | |||
The transportation sector is characterized by 14 energy-services plus one non-energy use demand segment (Table 3.3.1). Six of the energy-services are considered as generic demands: international and domestic aviation, freight and passenger rail transportation, domestic and international navigation (TWD, TWI). All other energy-services are for road transport. Demand for road transport energy-services is expressed in b-vkm and others are in PJ. The model projects energy-services demands for each region. | |||

Energy services demand
The transportation sector is characterized by 14 energy-services plus one non-energy use demand segment (Table 3.3.1). Six of the energy-services are considered as generic demands: international and domestic aviation, freight and passenger rail transportation, domestic and international navigation (TWD, TWI). All other energy-services are for road transport. Demand for road transport energy-services is expressed in b-vkm and others are in PJ. The model projects energy-services demands for each region.

Table 3.3.2 presents the list of transport fuels available to meet the base-year energy-service demand in each transport subsector.

No new investments are allowed for existing technologies. For each end-use, a number of existing technologies are in competition to satisfy the energy-services demand for future years. Efficiency and cost of these technologies improve over the period with vintages. These technologies progressively replace the existing ones and they are characterized by the same type of parameters such as efficiency, and investment cost. There are many new technologies available for the road transport sector whereas technological detail is very limited in rail, shipping and aviation modes. Investment and O&M costs shown are US dollar reference prices. They are multiplied by regionally specific factors for each region. Technology and regional specific hurdle rate, which are used to annualise the investment cost, are also applied.
Residential and commercial sectors
Commercial Sector
Commercial sector base-year final energy consumption is calibrated in the residential sector Base-Year template, which has separate sheets for commercial sector IEA data, sector fuel data, end-use technology data and emissions data. There are separate sheets available for technology data for each energy-service demand.
Energy services demand
The commercial sector includes eight energy service demands for each region as presented in Table 3.4.1. Some segments of the commercial sector energy-services are identified using more than one code, which means that the demand can be disaggregated in four or less sub-regions.When no sub-regions have been defined, the codes for sub-region 1 are used by default. Currently, USA and CAN have four and three geographic regions, respectively, while AFR, CHI, IND, MEA and MEX each have two ?sub-regions?, corresponding to rural and urban areas. The energy-service demands for the future period (2005-2100) are projected using appropriate drivers and elasticity.
