In 2021, when China banned bitcoin and other cryptocurrencies, crypto miners flocked to the United States in search of cheap electricity and looser regulations. In a few short years, the U.S.’s share of global crypto mining operations grew from 3.5 percent to 38 percent, forming the world’s largest crypto mining industry.
The impacts of this shift have not gone unnoticed. From New York to Kentucky to Texas, crypto mining warehouses have vastly increased local electricity demand to power their 24/7 computing operations. Their power use has stressed local grids, raised electricity bills for nearby residents, and kept once-defunct fossil fuel plants running. Yet to date, no one knows exactly how much electricity the U.S. crypto mining industry uses.
That’s about to change as federal officials launch the first comprehensive effort to collect data on cryptocurrency mining’s energy use. This week, the U.S. Energy Information Administration, an energy statistics arm of the federal Department of Energy, is requiring 82 commercial crypto miners to report how much energy they’re consuming. It’s the first survey in a new program aiming to shed light on an opaque industry by leveraging the agency’s unique authority to mandate energy use disclosure from large companies.
“This is nonpartisan data that’s collected from the miners themselves that no one else has,” said Mandy DeRoche, deputy managing attorney in the clean energy program at the environmental law nonprofit Earthjustice. “Understanding this data is the first step to understanding what we can do next.”
