Peru has been hit hard by climate change. It has seen natural disasters, damage to agriculture and water shortages. In the last 25 years glaciers in the Andes have shrunk by a quarter. And that is having a dramatic impact on water supplies. At the same time, the Andes hold huge potential for hydroelectric power. Peru already generates around 60 percent of its power from hydroelectric sources. But it could produce much more. Large parts of the country are not yet connected to the power grid. Over 5 million Peruvians have no normal power supply. But that could soon change thanks to an aid organization which is building micro hydroelectric power plants in remote parts of the Andes.
