Construction starts on world’s largest solar array

A groundbreaking will take place Monday at Nellis Air Force Base, just north of Las Vegas, Nevada, in the desolate, arid, windswept Mojave Desert. The ceremony will initiate construction on what will be the largest solar photovoltaic (PV) array in the United States, capable of producing 15-18 megawatts of power. The project highlights both the promise and the pitfalls of PV.
