Most global energy models are developed by institutes from developed countries, focusing primarily on issues that are important in industrialized countries. Evaluation of the results for Asia of the IPCC/SRES models shows that broad concepts of energy and development, the energy ladder and the environmental Kuznets curve, can be observed in the results of the models. However, improvements can be made in modeling the issues that underlie these concepts, like traditional fuels, electrification, economic structural change, income distribution, and informal economies. Given the rapidly growing importance of energy trajectories of developing countries for global sustainability, the challenge for the future is to develop energy models that include all these aspects of energy and development.
