Bitcoin mining, a process notoriously known for its high energy consumption, is increasingly turning towards renewable energy sources. This shift is driven by the pressing global concern over Bitcoin mining's significant issue of consuming an estimated 348 terawatt hours of electricity annually. Power industry professionals are actively seeking solutions and engaging in resource exchange on platforms such as Energy Central Power Industry Network®, with the aim of shaping the industry's response to this substantial challenge.
The Bitcoin network's computational power is largely hosted by the U.S., China, and Kazakhstan, accounting for about 75% of its total. These countries derive 22.5%, 30.2%, and 11.3%, respectively, of their electricity from renewables. Despite this, coal remains a key energy source in Kazakhstan and China, although China also heavily invests in wind and solar power.
Following China's crackdown on cryptocurrency mining in 2021, many miners relocated to Kazakhstan due to its affordable electricity, lax regulations, and political stability. Other significant contributions come from Ireland, Singapore, Thailand, and Germany, which collectively host a substantial portion of the network.
Miners often operate from mobile units known as 'Bitcoin mining shipping containers', choosing their locations based on regulatory regimes, electricity costs, and average temperatures. Interestingly, Canada has seen a rise in its network share to 6.5% due to its abundant hydroelectric resources.
However, countries rich in renewable energy like Iceland, Paraguay, and Norway have a minimal presence in the global Bitcoin network. This highlights the complexity of the transition to renewable energy within the Bitcoin mining industry and underscores the need for further efforts to address climate change concerns.
