100% renewable energy cheapest for South America  

RNE has an article on how to transition South America to 100% renewable energy - 100% renewable energy system cheapest for South America.

Transitioning to a fully renewable energy system, with over 50% coming from solar PV, would be the cheapest option for South America and it is possible in the next 15 years, according to research conducted by the Lappeenranta University of Technology.

As an ever-present accomplice to South America’s dramatic scenery, heavy sunlight could also be the dominant source of energy for the region by 2030, according to a new study from Finnish Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland. But this is not the only clean energy source that the region should adopt, as the study finds that a 100% renewable energy system, including numerous renewable technologies, would be the cheapest energy system option for the region, due to its rich solar, wind and hydro resources.
