Costs and consequences of wind turbine wake effects arising from uncoordinated wind energy development | Nature Energy, Nov 2018
Via Nature podcast
"Optimal wind farm locations require a strong and reliable wind resource and access to transmission lines. As onshore and offshore wind energy grows, preferred locations become saturated with numerous wind farms. An upwind wind farm generates ‘wake effects’ (decreases in downwind wind speeds) that undermine a downwind wind farm’s power generation and revenues. Here we use a diverse set of analysis tools from the atmospheric science, economic and legal communities to assess costs and consequences of these wake effects, focusing on a West Texas case study. We show that although wake effects vary with atmospheric conditions, they are discernible in monthly power production. In stably stratified atmospheric conditions, wakes can extend 50+ km downwind, resulting in economic losses of several million dollars over six years for our case study. However, our investigation of the legal literature shows no legal guidance for protecting existing wind farms from such significant impacts."

Windmap; an animated map of global wind - YouTube - Cameron Beccario
Via John Helm: the guy that wrote the nullschool wind map gives a conference talk about how he developed it "Cameron Beccario (@cambecc) talks about designing http://earth.nullschool.net/ which is an animated map of global wind and weather. Cameron spoke at The Graphical Web 2014 conference (http://www.graphicalweb.org/2014/) at The University of Winchester as organised by The Office for National Statistics."
