Energy Sector Water Use Implications of a 2C Climate Policy

Environmental Research Letters (2016, v11; 11 p034011; doi:10.1088/1748-9326/11/3/034011

[R&D Mag] Climate mitigation efforts in the energy system could lead to increasing pressure on water resources, according to a new study published in the journalEnvironmental Research Letters.Yet increased energy efficiency and a focus on wind and solar power, which require less water, or the switch to more water-efficient cooling technologies could help avoid this problem, the study shows.

The new study aimed to systematically pinpoint the drivers of water demand in the energy system, examining 41 scenarios for the future energy system that are compatible with limiting future climate change to below the 2°C target, which were identified by the IIASA-led 2012 Global Energy Assessment
