The future of the global energy system is highly uncertain and depends on factors such as technological innovations and breakthroughs, socio-economic developments, resource availability and societal choices. Exploring different scenarios for developments around the use and supply of energy provides information for decision-makers to base strategic policy decisions. | The future of the global energy system is highly uncertain and depends on factors such as technological innovations and breakthroughs, socio-economic developments, resource availability and societal choices.

The energy model TIMER focuses on long-term trends in energy supply and demand. It was mainly developed for analysing climate mitigation strategies and has also been used to explore other sustainability issues. These characteristics impose some limitations on the model. Firstly, the model cannot be used to examine macroeconomic consequences of mitigation strategies, such as GDP losses, because other aspects of the economy are not included. Secondly, the strategies depicted by the model are not necessarily optimal from an inter-temporal perspective because as a simulation model, there is no information on future development in a scenario (myopic). Instead, decisions are made on the basis of available model information at that time in the scenario. Finally, although the model has been used to analyse sustainability issues other than climate change, still much less options have been included to explore such policies (see [[Air pollution and energy policies]]). | The energy model TIMER focuses on long-term trends in energy supply and demand.
