The GEO-TIMES model is a global energy system model developed under the CIMERA project with 31 regions and 20 time slices. It models the energy system from primary extraction through transformation and delivery to end use sectors. Key accomplishments include 16 journal publications, innovative national and global energy models, and contributions to scientific communities. The model is calibrated to 2018 UN energy statistics and includes CO2, CH4, N2O and other greenhouse gas emissions. Future improvements may include better linking with economic and demographic drivers, expanding technology details, and developing energy transition indicators.
