EU Ruling Slackens Poland’s Coal Power Expansion Ambitions
Poland, a country that currently depends on coal power for nearly 85% of its electricity and plans to build another 11,300 MW of new coal-fired capacity by 2020, suffered a critical planning setback in mid-July as the European Union (EU) effectively blocked the country from using free carbon emission permits to build new coal-fired power plants.
