|Description=In the baseline scenario, energy demand is projection to grow significantly during the 21st century. Most of the demand growth is driven by a growth in energy use in developing countries. In fact, per capita use in developed countries is project to remain more-or-less constant (consistent with historical trends). The increase in energy demand, is mostly met by electricity (in the first half of the century), fossil fuels and in the long-run also hydrogen (in transport).

|Description=Under the baseline scenario, energy demand is projected to grow significantly during the 21st century. Most growth will be driven by an increase in energy use in low-income countries. In high-income countries, per-capita use is projected to remain more or less constant, consistent with recent historical trends. The increased demand for energy mostly will be met by electricity (in the first half of the century), fossil fuels, and in the long run also by hydrogen (that enters the transport as a result of increasing oil prices and the assumed progress in hydrogen technologies).  
|Example=An example of several of these interventions forms the study “Resource Efficiency”. Here, the TIMER model was used to explore the impact of radically improving energy efficiency. This, for instance, included the information of best-available technologies in iron and steel production and other industries, the implementation of the most efficient cars and aircraft is assumed, a moderate shift is assumed from aircraft to high speed trains,and building of highly efficient housing (mostly insulation measures). It was also assumed that new power plants would be based on best-available technologies. New plants in all regions are assumed to be built on the basis of efficient technologies. The measures assumed in this global energy efficiency scenario are able to considerably reduce energy use. Primary energy consumption is reduced from X to Y EJ/yr (primary energy) in 2050, which corresponds to a reduction by about 30% as compared to the baseline. The results show that the RE scenario is able to more-or-less half the gap between baseline CO2 emissions and the emission reductions required to restrict temperature increase - with a high degree of probability - to a maximum of 2°C.
 
|Example=The PBL study ‘Resource Efficiency’ ([[Van den Berg et al., 2011]]) provides an example of how the TIMER model can be used to explore the impact of radically improving energy efficiency. That study includes, amongst other things, an accelerated trend towards best-available technologies in iron and steel production and other industries, the implementation of the most efficient passenger vehicles and aircraft, a moderate shift from aircraft to high-speed trains, and building highly efficient housing (mostly insulation measures). The study also assumes that newly installed power plants will be based on the best available technologies. The measures in this global energy efficiency scenario will lead to a considerably lower energy use than under the baseline scenario. Primary energy consumption will be reduced by about 30% by 2050.
