However, substantial variability among current wind resource and power simulations used for wind farm deployment limits the reliability of siting and system integration decisions. Therefore, we present a transparent, open source, validated and evaluated, global wind power simulation workflow for the renewable energy simulation tool ETHOS.RESKit. As the first wind simulation workflow using the new Global Wind Atlas 4 and the fifth iteration of the European Center for Medium-Range Weather Forecasts Reanalysis, it is capable of simulating time-resolved energy output of wind turbines with high spatial resolution and customizable designs for both onshore and offshore wind turbines. The tool has undergone an exNature communicationsTowards high resolution, validated and open global wind power assessments.PMC12804690Energy System Design101006632491111487Gruber KKlutz TMaier RStolten DHeinrichs HWinkler CPrinz FPena-Sanchez EULinßen JDunkel PDickler SChen SWeinand JMfalseTowards high resolution, validated and open global wind power assessments.Wind power is widely recognized as a key component of future net-zero energy systems.
