In the initial months of 2024, United States-based Bitcoin miners have encountered significant electricity expenses amounting to $2.7 billion. According to analyst Paul Hoffman from Best Brokers, Bitcoin mining operations in the US have consumed 20,822.62 gigawatt-hours (GWh) of electricity since the beginning of the year. Considering an average commercial electricity rate of $0.1281 per kilowatt-hour (kWh), this has resulted in an expenditure of $2,667,378,196.47 as of February.

Energy Consumption and Comparisons

Hoffman further explained that the energy utilized in Bitcoin mining could power every electric vehicle in the US 87.52 times or sustain 1,983,107 households for a year, equivalent to 1.51% of all US households. On a global scale, 116,550 Bitcoins, valued at $8.2 billion, have been successfully mined so far, with US miners contributing 44,102 Bitcoins or 37.84% of the total global output. Prior to the April halving event, the electricity required to mine one Bitcoin stood at 407,059.01 kWh, amounting to a cost of approximately $52,144.26. Following the halving, this figure rose to 862,635.55 kWh, significantly increasing the cost to around $110,503.61.

Evolution in the Mining Industry

Despite the substantial energy consumption, Bitcoin mining stands out as one of the few major global industries primarily backed by sustainable energy sources. Data from the Bitcoin ESG Forecast in January showcased that sustainable energy adoption in Bitcoin mining has reached a record 54.5%, marking a 3.6% increase from 2023. Following the imposition of mining bans in countries like China and Kazakhstan, miners have pivoted towards greener energy grids in North America and sustainable off-grid locations. As of now, out of the total supply of 21 million Bitcoins, 19.5 million have already been mined.

Key Observations for Stakeholders

• Bitcoin mining in the US emerges as a substantial electricity consumer, with costs surpassing $2.7 billion in the early months of 2024.
• The electricity utilized in Bitcoin mining could alternatively support almost 2 million US households on an annual basis.
• Following the April 2024 halving event, the electricity needed to mine one Bitcoin has doubled, resulting in a significant rise in mining expenses.
• Sustainable energy utilization in Bitcoin mining has achieved a peak, indicating a shift towards eco-friendly practices.
• Mining restrictions in various nations have prompted miners to embrace more sustainable energy sources, particularly in North America.

Given these developments, environmental considerations remain a key focus, with experts engaging in discussions concerning the environmental impact of Bitcoin mining. The growing adoption of renewable energy in mining operations and the retirement of numerous mining devices post the Bitcoin halving event remain pivotal points of ongoing conversations.
