Carving out the narrowed girth of southern Mexico, the Isthmus of Tehu-antepec is home to a anemometric quality that is nearly unmatched. Wind is valuable here, its steady pulse an ideal quotient of kinetic force to turn the blades of turbines that, in turn, make electricity. With this wind develop-ment might follow; with this wind new wealth might follow. And these are two of the reasons why the Oaxacan isthmus now represents the densest concentration of wind parks on land anywhere in the world. But in this wind other things are also gathered and captured: birds and turtles, trucks and barricades, dirt and money.
