A solar farm under construction in Punta Gorda, Florida, on April 22, 2016 where enough energy will be produced to power 21,000 homes. With deep pockets and an environmentalist's zeal, retired American football player Syd Kitson dreamed up a plan to build the United States' first solar-powered town on a vast swath of rural land in southwest Florida. Nearly a decade after he first purchased the 91,000 acres (37,000 hectares) known as Babcock Ranch, construction is bustling at what developers say will be the nation's first eco-friendly city, built from the ground up, with enough room for some 50,000 people. / AFP PHOTO / Kerry SHERIDAN / TO GO WITH AFP STORY BY KERRY SHERIDAN-"Construction is bustling at Florida's first 'sustainable town" (Photo credit should read KERRY SHERIDAN/AFP/Getty Images)
