While the unstoppable growth of solar power seems to have gained a foothold in Brazil, countries with a temperate climate and much smaller territory, such as Germany and Spain, produce much more solar energy. Brazil, which has the largest territorial area in the tropics, meaning a huge amount of sun, is simply not taking advantage of its situation.
