Integrated energy and environment modeling system and application for India

Integrated modeling system offers advantages over a huge monolith model in addressing diverse issues in energy and environment modeling for a vast country like India. It utilizes the inherent stengths of strong individual top-down and bottom-up models that are best suited to address specific energy and environment issues. The integrated modeling system soft links these models through consistent and similar assumptions for all the models, a shared database and talking between the models as against hard linking them through model codes and runs. Multiple feedback is required among the models to ensure consistency of results and policy analysis. The paper discusses an integrated modeling system for India that uses ten models and presents some results to highlight their in-depth coverage and capability to address energy and environmental concerns.
