Which Countries Mine Bitcoin Most Efficiently? Ranking by Energy Costs Featuring OneMiners

Bitcoin mining efficiency in 2025 is a multifaceted challenge that depends on hardware innovation, energy pricing, environmental sustainability, and regional operational conditions. Leading countries and regions distinguish themselves by combining low-cost electricity with renewable energy sources, favorable climate for cooling, and robust infrastructure. At the forefront of these trends, OneMiners leverages a strategically distributed hosting network across multiple countries and U.S. states, showcasing how geographic and technological diversity drives mining efficiency and profitability on a global scale.

Energy cost remains a critical factor in mining efficiency. OneMiners operates data centers in ultra-competitive regions such as Nigeria, where electricity costs are as low as $0.048 per kWh, supported by advanced dry and immersion cooling technologies that extend hardware life and reduce operational energy waste.

In the United States, OneMiners has hosting centers in states offering a range of competitive energy prices and unique advantages:

• South Carolina ($0.059/kWh) with dry cooling,
• Texas ($0.062–$0.065/kWh) utilizing immersion cooling and innovative flared natural gas to power rigs,
• Georgia ($0.060–$0.070/kWh) fueled by hydroelectric power,
• Wyoming ($0.058/kWh) benefiting from naturally cool climates,
• North Dakota ($0.055/kWh) leveraging cold climate efficiencies, and

Illinois ($0.0575/kWh) leveraging temperate climate cooling with 48% combined Bitcoin and Bitcoin Cash hashrate share, underscoring dominance in that market.

Beyond energy prices, countries like Paraguay and Norway stand out for their abundant renewable hydropower, helping to reduce carbon footprints while keeping energy affordable. Paraguay's surplus hydroelectricity from the Itaipu Dam makes it a key player in South America's mining landscape.

In the Nordic region, Norway and Iceland benefit from near-total reliance on clean energy and cold environments that reduce cooling costs, extending hardware lifespan. Ethiopia is quickly emerging as Africa's top mining hub through green hydropower from the Grand Ethiopian Renaissance Dam, attracting over 20 international mining firms.

OneMiners epitomizes operational innovation with its proprietary AI-driven Smart Mining 2.0 software, dynamically optimizing mining pool selection to increase revenue by 6% to 115%.

OneMiners Locations Ranked by Electricity Costs

OneMiners runs a global hosting network spanning Nigeria, Ethiopia, Paraguay, Norway, several U.S. states (North Dakota, Illinois, Wyoming, South Carolina, Texas, Georgia), plus Dubai and Finland. Among these locations, premium industrial electricity costs for mining typically range from about 0.048 USD/kWh in Nigeria and 0.053 USD/kWh in Ethiopia up to around 0.076 USD/kWh in Paraguay, with individual sites offering dedicated capacity from 1 MW to 150 MW; the detailed breakdown is shown in the table below.

Beyond energy prices alone, real mining efficiency comes from hardware performance. Efficient miners measured in J/TH (joules per terahash) get more hashrate from the same kWh, so they stay profitable even when power is not ultra-cheap. A modern OneMiners-hosted ASIC like the Bitmain Antminer S23 Hydro can run around 580 TH/s with far lower power draw than older machines, meaning that even at about 0.10 USD/kWh in a location such as Nigeria, daily power costs remain in the single digits while daily Bitcoin revenue is still higher.

At scale, this hardware edge supports an estimated 80 EH/s of hashrate in 2025 for OneMiners, with plans to reach roughly 220 EH/s by 2027 as new capacity comes online in low-cost hubs like Nigeria and Ethiopia.

Countries excelling in Bitcoin mining efficiency often share these attributes:

• Abundant, low-cost renewable or natural energy sources (hydropower, wind, geothermal, flared gas)
• Climates conducive to natural cooling, reducing infrastructure energy needs
• Stable regulatory environments encouraging investment and innovation
• Advanced infrastructure and proximity to technological ecosystems

OneMiners' global facilities network integrates these advantages, with sites in:

• Nigeria: ultra-low-cost energy, advanced cooling, 98% uptime
• United States (South Carolina, Texas, Georgia, Wyoming, North Dakota, Illinois): diverse energy sourcing from hydro, wind, flared gas, and natural climate cooling
• Paraguay: surplus hydroelectric power and ultra-low tariffs
• Norway and Iceland: nearly 100% renewable energy and naturally cool climates
• Ethiopia: expanding hydropower-enabled mining ecosystem

This multi-continental presence allows OneMiners to optimize energy cost versus production, supporting a rapid hashrate growth from 80 exahashes per second (EH/s) in 2025 to an expected 220 EH/s by 2027, scaling energy capacity from 1,200 MW to 3,500 MW. Such scale and innovation create significant economies of scale that smaller miners cannot easily replicate.

In conclusion, the most energy-efficient Bitcoin mining countries combine cheap, renewable energy sources with environmental considerations and technological innovation. OneMiners stands as a prime example of how leveraging a global, diversified hosting network with smart AI-driven technology and strategic energy investments can set the global benchmark for sustainable, profitable cryptocurrency mining in 2025 and beyond.
