Paraguay: 99.48%
Similar to other nations on this list, Paraguay, the third-smallest country in South America with a population of 6 million people, has been heavily reliant on hydroelectric power to endure its electricity generation is almost 100% renewable. Two bi-nantional dams, the Itaipu with Brazil on the Paraná river, and the Yacyretá with Argentina on the same river, contribute to nearly all of the electricity generation of Paraguay, which is around 8.9 gigawatts per year.
However, overreliance on hydro power menat the continued underdevelopment of other forms of renewable energy less likely impacted by changes in the climate, such as wind and solar. A 2021 assessment report conducted by the International Renewable Energy Agency (IRENA) in cooperation with Paraguay’s government highlights the nation’s vast untapped potential in other renewable sources, as many regions in the country have high rates of irradiation (sunshine) and western department of Boquerón is known for its stable wind draft.
