CAMAGUEY, CUBA - DECEMBER 01: A horse and buggy walk past a sugar cane harvester as the tractor is being refueled on December 1, 2016 in Camaguey, Cuba. With the death of former Cuban President Fidel Castro, an opponent to the use of farmland for the production of biofuels, Cuba may now be able to build bioelectricity plants that could generate as many as 750 megawatts with sugarcane biomass and other forestry products.
