As a country without fossil fuel resources, Uruguay has undergone a fundamental change, transforming itself from a fossil fuel importer into a renewable energy exporter. The country already generates almost all of its power from renewable energy sources, with wind turbines contributing almost a third. Other relevant renewable power sources include hydro, bioenergy and solar. José Cataldo, a professor with focus on wind power at the Universidad de la República de Uruguay, played an instrumental role in developing the country's wind power programme. In this episode, he describes how the country has reached important milestones, the main drivers and the barriers that have had to be overcome. The main lesson is that it is important to make use of one's own resources, which offer room for future growth.
