When it became one of the largest cryptocurrency mines in the U.S., its greenhouse gas emissions increased almost ten-fold between 2019 and 2020. Greenidge plans to double its mining capacity by July, then double it again by 2022 and wants to convert more power plants to mining by 2025. While Greenidge pledged to become carbon neutral in June through purchasing carbon offsets, the fact remains that without bitcoin mining, the plant would probably not be running at all.
