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.

However, in the past data were about statistical energy use. For the future, trends were extrapolated and denoted as energy demand, which in the model is assumed to be fully supplied and thus equal to use.</ref>. The model simulates long-term trends in energy use, issues related to depletion, energy-related greenhouse gas and other air polluting emissions, together with land-use demand for energy crops. The focus is on dynamic relationships in the energy system, such as inertia and learning-by-doing in capital stocks, depletion of the resource base and trade between regions.

===Overview of TIMER===
The energy model has three components: energy demand; energy conversion; and energy supply (see Figure Flowchart). The energy demand component describes how energy demand is determined for five economic sectors -industry, transport, residential, services and other sectors. The energy conversion components describes how carriers such as electricity and hydrogen are produced. Finally, the energy supply modules describe the production of primary energy carriers, and calculate prices endogenously for both primary and secondary energy carriers that drive investment in the technologies associated with these carriers. The energy flows in all three main components allow calculation of greenhouse gas and air pollutant emissions.
