Costa Rica, with a population of 4.8 million, generated 100 percent of its electricity from renewable resources the first quarter of 2015 primarily from hydroelectric and geothermal sources. Ample rainfall at four of the country’s main hydroelectric plants enabled this milestone. In 2014, hydropower accounted for about 80 percent of the country’s electricity, with geothermal from volcanoes contributing 10 percent. With goals to become carbon-neutral by 2021, Costa Rica plans to add three large geothermal plants that are expected to provide 150 MW of clean power. For more information and LAHT
