|Description=The supply of different energy resources obviously forms a key component of the energy system. On the one hand, supply is constrained on an annual (for renewables) or cumulative (for fossil and nuclear) basis. In addition, resources are unevenly spread across world regions and often poorly matched with regional energy requirements. It relates directly to the notion of energy security, but also determines to a large extent the many environmental impacts of the energy system. The IMAGE energy model [[TIMER model|TIMER]] concentrates on long-term dynamics, not on short term market conditions. For all primary energy carriers, costs are based in the long run on the interplay between resource depletion (upward pressure on prices) and technology development (downward pressure on prices). In the model, technology development is introduced for most fuels and renewable options as learning curves: costs decrease endogenously as a function of cumulative capacity in place in some cases exogenous technology change assumptions are made. Depletion is a function of either cumulative production, as for fossil fuel resources and nuclear feedstocks, or of annual production as for renewables. | |Description=The supply of different energy resources obviously forms a key component of the energy system.

Key policy issues
- How can energy resources be exploited to meet future primary energy demand?
- How can energy supply and demand be balanced between world regions, and how will this effect security of supply?
- How rapidly can the transition to more sustainable energy supply be made?
