“…There are also non-physical barriers to siting wind farms, ranging from investment and maintenance costs [ 53 , 54 ], to setback distances and other regulations [ [55] , [56] , [57] ], to public opinions about wind energy [ [58] , [59] , [60] ]. Improper wind farm siting decisions can have real-world consequences, such as high bird mortality rates in California's Altamont Pass [ 61 ] and Northern Portugal [ 62 ], as well as public opposition leading to project cancelations in Greece [ 63 ], Canada [ 64 ], and, famously, the United States' Cape Wind project [ 65 , 66 ]. As the wind energy sector grows in the coming decades, competition to construct commercial wind farms in profitable, low-impact locations will increase, thereby also increasing the salience of careful wind farm site selection.…”
