Water for electricity: resource scarcity, climate change and business in a finite world
This report examines the potential impact of low carbon electricity generation technologies on water resources and how these water considerations might shape renewable generation choices. The report notes that some low carbon energy sources require considerable amounts of water and given competing demands, resource depletion and projected climate impacts, sufficient water may not always be available. The report explores the ways in which a changing climate and associated hydrologic changes may affect electricity generation strategies; in particular, where future climate change may significantly decrease water availability. It examines the water use implications of different electricity generation pathways, as well as potential ways to reduce the water use of electricity generation technologies.
