Brazilis best known for its lush rainforests and rich biodiversity. And now the government is hoping to make its energy infrastructure greener too. This week on Global Ideas, reporter Joachim Eggers takes us to the city of Florianópolis in southern Brazil, where the country’s largest solar power plant is being built. It has yet to supply large amounts of energy, but it is considered an important green model for investors as well as Brazilians. The latter are also embracing another green initiative - the bicycle. And that’s despite the fact that around 40 percent of all households in Brazil own at least one car. Not just children but adults too are increasingly learning to push the pedals. In our background article, Greta Hamann interviews a Brazilian professor who shares her experiences re-learning how to ride a bike, and the challenges facing cyclists in her city every day.
