The US Department of Energy is conducting an emergency survey of crypto miners in response to the recent surge in Bitcoin prices. The survey, authorized by the Office of Management and Budget, will require mining firms to provide detailed documentation on their energy consumption. The Energy Information Administration aims to better understand the energy demands of cryptocurrency mining, identify areas of high growth, and quantify the sources of electricity used. Lawmakers have raised concerns about the industry's energy appetite and climate impacts, prompting government efforts to quantify electricity usage in the growing crypto-mining industry.
