Every morning in the Tumakuru District of Karnataka, a state in southern India, the sun tips over the horizon and lights up the green-and-brown hills of the Eastern Ghats. Its rays fall across the grasslands that surround them and the occasional sleepy village; the sky changes color from sherbet-orange to powdery blue. Eventually, the sunlight reaches a sea of glass and silicon known as Pavagada Ultra Mega Solar Park. Here, within millions of photovoltaic panels, lined up in rows and columns like an army at attention, electrons vibrate with energy. The panels cover thirteen thousand acres, or about twenty square miles—only slightly smaller than the area of Manhattan.
