The cryptocurrency mining industry has undergone a significant shift in recent years, with the United States emerging as the new global hub for bitcoin mining operations. This transition began in 2021 when China, previously home to nearly 70% of global crypto mining, implemented a ban on such activities. The move was driven by concerns over illegal financial activities and risks to China’s financial system, according to Zongyuan Zoe Liu of the Council on Foreign Relations.
Following China’s crackdown, mining companies initially relocated to Kazakhstan, attracted by its abundant coal power. However, the sudden influx of miners led to a surge in energy consumption, causing widespread power outages and public outcry. This prompted many operations to seek a new home, with the United States becoming their primary destination.
Today, the U.S. accounts for approximately 40% of the global hashrate, a measure of the computational power used in bitcoin mining. This marks a substantial increase from its 17% share during China’s peak in 2021. The country now hosts 52 cryptocurrency mining operations, collectively consuming about 2% of America’s total energy output – equivalent to powering entire states like Utah or West Virginia.
While this migration has not resulted in a crisis similar to Kazakhstan’s, it has sparked local opposition and raised concerns about the involvement of Chinese-owned operations. The
energy-intensive nature of crypto mining, which requires solving increasingly complex mathematical problems, has put a strain on local power grids and resources.
In Rockdale, Texas, a single Riot Platforms mining facility uses 450 megawatts of energy, enough to power approximately 300,000 homes. This level of consumption has alarmed environmental advocates like Jeremy Fisher of the Sierra Club, who warns that the industry’s growth contradicts efforts to increase renewable energy generation and reduce reliance on fossil fuels.
Local communities across the U.S. have begun to push back against these operations. Residents in towns like Murphy, North Carolina, and Massillon, Ohio, have organized petitions, coalitions, and awareness campaigns to voice their concerns. Issues range from excessive noise pollution to fears of rising electricity costs and environmental impact.
The crypto industry has responded by ramping up its lobbying efforts. In California, the industry spent over $400,000 on lobbying, successfully influencing Governor Gavin Newsom to veto a bill that would have established regulatory frameworks for digital financial assets. At the federal level, bitcoin lobbyists have invested more than $20 million to prevent SEC oversight of cryptocurrencies.
The concentration of mining power in the hands of a few large companies has also raised questions about the decentralized nature of cryptocurrencies, a key selling point for many enthusiasts. A 2021 study by the National Bureau of Economic Research found that just 10% of miners controlled 90% of bitcoin mining capacity.
As the industry grows, concerns about foreign ownership, particularly from China, have emerged. In Arkansas, public backlash led to new regulations addressing noise reduction, proximity to residential areas, and foreign ownership of mining operations. The Biden administration has also taken action, ordering a Chinese-owned mining company to divest from its facilities near a nuclear missile base in Wyoming, citing national security concerns.
The future of cryptocurrency mining in the U.S. remains uncertain. While some local governments see potential economic benefits, others are considering moratoriums on new facilities. As the debate continues, policymakers and communities alike are grappling with the challenge of balancing technological innovation with environmental sustainability and community well-being.
