New York became the first state to enact a temporary ban on new cryptocurrency mining permits at fossil fuel plants in a move aimed at addressing the environmental concerns over the energy-intensive activity. The legislation, signed by Gov. Kathy Hochul, will impose a two-year moratorium on crypto-mining companies seeking new permits to retrofit some of the state’s oldest fossil fuel plants into digital mining operations.

Since the inception of cryptocurrency mining over a decade ago, the state of New York has become a hotspot for the digital coins, encompassing 19.9 percent of the total U.S. hashrate, or the collective computing power of miners. However, concerns over the environmental impacts of, and high electricity demands for, these mining operations have been increasingly thrust into the spotlight.
