A REVIEW OF LESSONS FROM COMBINED MODELLING APPROACHES IN ASSESSING ENERGY AND CLIMATE POLICIES.

The migration of the current energy system towards a system with a high penetration of renewable energy sources is necessary if the catastrophic impacts of climate change are to be prevented. The interdependencies of such energy system security to the human and ecosystem well-being calls for a more cross-disciplinary analysis of the policy space as recommended in the nexus approach. System modelling can play a significant role in addressing these complexities. However, this is best achieved if models expand their analysis horizon beyond the energy system and incorporate all nexus components. This paper developed a set of evaluation approaches to map the gaps in the adequacy of existing energy system models' capabilities and potentials in representing the nexus concept.
