A group of Democratic lawmakers led by U.S. Senator Elizabeth Warren is demanding details from six of the world’s biggest Bitcoin miners about their electricity consumption and greenhouse-gas emissions, a warning shot that comes amid growing concern over the cryptocurrency industry’s environmental impact. 

The eight lawmakers sent letters Thursday asking miners including Marathon Digital Holdings Inc. and Riot Blockchain Inc., to provide their facilities’ annual electricity consumption, growth plans and impact on local power prices.
