Future energy demand will be affected by changes in prices and income, but also by other factors, like temperature levels. This paper draws upon an econometric study, disentangling the contribution of temperature in the determination of the annual regional demand for energy goods. Combining estimates of temperature elasticities with scenarios of future climate change, it is possible to assess variations in energy demand induced (directly) by the global warming. We use this information to simulate a change in the demand structure of households in a CGE model of the world economy, in a set of assessment exercises. The changing demand structure triggers a structural adjustment process, influencing trade flows, regional competitiveness of industries and regions, and welfare. We also consider the possible existence of imperfect competition in the energy markets, analyzing the impact of changes in energy demand with an alternative model version, in which energy industries are modeled as Cournot oligopolies.
