This nation is scorching in a heat wave and wildfires, yet it's returning to planet-baking coal

Just a year ago, Greece was confident it could close all existing coal-burning plants by 2023. But an energy crunch that has turned into a full-blown crisis since Russia invaded Ukraine has sent that whole timeline up in smoke.

It's funny to Mitsaris because just until December last year, the 40-year-old had spent 17 years of his life working the coal mines for the state-run Public Power Corporation (PPC) to keep the lights on in people's homes. He finally gave up coal for wine, understanding that the fossil fuel was on its way out.

Mitsaris, whose father also worked in coal mining, bought 44 acres of vineyard. But he's now wondering if he made the right choice -- coal here is refusing to quit.
