Costa Rica has generated 100 percent of its electricity from renewable energy 150 days so far this year, including all of the past two months, according to the Costa Rican Institute of Electricity, the nation’s main power provider. The country’s main source of renewable energy is hydropower, which accounted for 80 percent of Costa Rica’s electricity generation in August, according to Mashable. Another massive hydroelectric power plant, the ReventazÃ³n dam, is scheduled to come online in September, further boosting the nation’s hydroelectric production. Geothermal, powered by Costa Rica’s many volcanoes, generated another 12.6 percent of electricity. Wind and solar make up roughly 7 percent of generation. Experts say Costa Rica is on track to meet, if not beat, last year’s record 299 days of 100 percent renewable energy.
