The overall objective of this project is to understand the nexus between water demand and greenhouse gas (GHG) emissions for different energy pathways. There is a trade-off between GHG mitigation and water consumption for energy scenarios. This project is aimed investigating this trade-off. This will be done through integration of Long-range Energy Alternative Planning systems model (LEAP) which is focused on estimation of GHG emissions and Water Evaluation And Planning system (WEAP) which is focussed on estimation of water demand for energy scenarios. Both these models are bottom-up technology driven models and include detail characteristics of energy demand and supply sectors. The LEAP model for Canada and the WEAP model for Alberta. The focus of the research would be on large Canadian industrial sectors.
