Here we use a global hydrological-electricity modelling framework to quantify the impacts of recent drought and warm years on hydropower and thermoelectric power usable capacity worldwide. Our coupled modelling framework consists of a hydrological model, stream temperature model, hydropower and thermoelectric power models, and was applied with data of a large selection of hydropower and thermoelectric power plants worldwide. Our results show that hydropower utilisation rates were on average reduced by 5.2% and thermoelectric power by 3.8% during the drought years compared to the long-term average for 1981-2010. Statistically significant (p < 0.01) impacts on both hydropower and thermoelectric power usable capacity were found during major drought years, e.g. 2003 in Europe (-6.6% in hydropower and -4.7% in thermoelectric power) and 2007 in Eastern North America (-6.1% in hydropower and -9.0% in thermoelectric power). Our hydrological-electricity modelling framework has potential for studying the linkages between water and electricity supply under climate variability and change, contributing to the quantification of the 'water-energy nexus'. date: 2016-12-12 date_type: published publisher: Institute of Physics Publishing (IOP) id_number: doi:10.1088/1748-9326/11/12/124021 creators_browse_id: 350 creators_browse_id: 329 full_text_status: public publication: Environmental Research Letters volume: 11 number: 12 pagerange: e124021 refereed: TRUE issn: 1748-9326 projects: Water futures and solutions initiative (WFaS) coversheets_dirty: FALSE fp7_project: no fp7_type: info:eu-repo/semantics/article citation: van Vliet, M. , Sheffield, J., Wiberg, D. , & Wood, E.F.
