Gigawatts of solar could be built in the open land around U.S. interstate highways

Sure, there are challenges to developing solar PV in federal highway rights of way. But in the past year, some of the biggest roadblocks have been cleared away. Most notably, the Federal Highway Administration in April instructed state agencies to put those rights of way to use for ?“clean energy and connectivity” projects like high-voltage transmission, broadband internet, EV charging and solar and wind power…

Figuring out just how big solar could get along the U.S. interstate highway network has been one of The Ray’s missions since its 2014 founding as a test bed for technology along an 18-mile-long stretch of Interstate 85 in western Georgia. The group’s first project was a 1-megawatt solar array and an EV charging station at a rest stop near the Alabama border.
