When the sun goes down, the wind picks up in central New Mexico, whipping through arid canyons with a ghostly howl that for centuries, locals have likened to the wails of the folkloric ghost La Llorona.

A few hours east of Albuquerque, this June, those gusts began powering the largest wind farm this continent has ever seen, twirling over 900 colossal steel turbines. Each is as tall as the Statue of Liberty, scattered across a patch of desert roughly the size of Chicago. They plug into a 550-mile transmission line stitched across the Southwest and are now powering over 1 million homes — as far away as California.

The SunZia Wind and Transmission project is a rare 21st-century triumph of American infrastructure, an engineering marvel that generates more electricity than the Hoover Dam. When the turbines came online this spring, they immediately broke records for wind-generated power in California’s energy supply, where solar power may rule the day, but the winds of New Mexico increasingly fuel the night.

After years of stagnant power growth, the U.S. is absolutely starving for more electricity, with demand projected to rise by 25 percent by the end of this decade, and a staggering 78 percent by 2050. Enormous as this challenge might seem, it may ultimately be the catalyst the country needs to dramatically dial up its renewable energy infrastructure, so that the years to come are powered not by gas or coal, but by clean energy sources like the sun and the wind. By next summer, the project will have prevented about 9 million metric tons of carbon dioxide from entering the atmosphere, according to Pattern Energy, the project’s developer.
