U.S. Senator Elizabeth Warren is pressing a Bitcoin miner about the impact of its operations on climate change, the local environment and power prices as part of her campaign to crack down on wasteful cryptocurrency mining.

Warren sent the letter to Greenidge Generation Holdings Chief Executive Officer Jeff Kirt on Thursday afternoon. Greenidge, which says it’s the first carbon-neutral Bitcoin miner in the U.S., has one mine in upstate New York and is planning another in South Carolina.
