Two main families of models have been developed over the decades. One is the energy system models, based on optimization of technology choices in production, distribution and consumption of energy. The other is economic computable general equilibrium models, based on optimizing economic agents whose interaction in markets (including energy markets) determines equilibrium prices and quantities. Over time, the two traditions have adopted features from each other and included more of the real-world complexities (such as behavioural and market barriers). The purpose of our analysis is to study the similarities and differences between the two modelling approaches in the context of energy efficiency policies. We have analysed the same policy-energy efficiency targets in households-using two models of different modelling traditions. The models generate fairly different results, particularly in the electricity market. Methods We study energy efficiency policies in households in an energy system model, TIMES-Norway (Lind and Rosenberg, 2013) and in a computable general equilibrium (CGE) model for Norwegian economy, SNOW-NO (Bye et al., 2015).
