Energy Modeling and Pathways
Researchers at the International Energy Analysis Department have developed and continually refined detailed, bottom-up national energy end-use models to evaluate potential future pathways and road maps for two key countries with fast-growing energy demand: China and India. Begun in 2005 in response to a growing policy focus in the Chinese government on energy efficiency, we developed the China 2050 DREAM model. This was followed by the development of the India 2050 DREAM model, and work is currently underway to develop similar national models for Mexico, Indonesia and South Africa. These models build on detailed stock turnover modeling for end-uses developed in BUENAS. 
Our national models have been used to:
- Perform detailed energy and emissions analyses at national, sectoral and technology levels
- Conduct retrospective and prospective sectoral and cross-cutting policy impact evaluation
- Evaluate energy demand and supply options
- Develop medium- and long-term outlooks for low-emissions pathways for greenhouse gases and air pollutants
Modeling Capabilities and Applications
Local impacts in cities are another focus. To this end, we've developed GREAT, a regional modeling tool applicable for subnational regions or cities. GREAT helps local governments explore potential energy and emission reduction opportunities and create action plans for low carbon development. Users such as energy policy analysts and researchers can customize the model to a given city or region by entering detailed data to develop scenario pathways.
Policymakers and city planners in the Chinese cities of Shenzhen, Guangzhou and Jinan have used GREAT to inform the development of their city energy and environmental plans.
