Last year, Costa Rica powered itself using only renewable energy for 75 days. It has topped that feat this year. Vox reports: Costa Rica is pulling off a feat most countries just daydream about: For two straight months, the Central American country hasn't burned any fossil fuels to generate electricity. That's right: 100 percent renewable power. This isn't a blip, either. For 300 total days last year and 150 days so far this year, Costa Rica's electricity has come entirely from renewable sources, mostly hydropower and geothermal. Heavy rains have helped four big hydroelectric dams run above their usual capacity, letting the country turn off its diesel generators. Now, there's a huge, huge caveat here: Costa Rica hasn't eschewed all fossil fuels entirely. The country still has more than 1 million cars running on old-fashioned gasoline, which is why imported oil still supplies over half its total energy needs. The country also has cement plants that burn coal.
