Crypto mining operations vary widely, from massive facilities under the Texas sun to compact setups in Italy’s snowy Alps. This photo essay explores diverse mining farms across Europe, Asia, and North America, shedding light on an often-misunderstood industry.
The Diversity of Crypto Mining Farms
The crypto mining industry is shrouded in secrecy due to security concerns and regulatory uncertainties. Many miners began as entrepreneurs tapping directly into hydropower plants in China, contributing to the sector’s controversial reputation. Public perception often focuses on large-scale operations fueled by fossil fuels or electricity theft, but the reality is far more nuanced.
🔍 Key Insight: Mining farms increasingly use renewable energy, innovating to improve efficiency and sustainability.
Kryptovault, Hønefoss, Norway
Located an hour outside Oslo, Kryptovault operates a 40-megawatt mining farm in Hønefoss. The cold climate reduces cooling costs, while excess heat is repurposed to dry wood for a local lumber company.
- Capacity: 18MW currently active (of 40MW total)
- Machines: Transitioning from Bitmain Antminer S9s to more efficient S19s
- Innovation: Noise-canceling panels installed after neighbor complaints

Southern Spain: Solar-Powered Mining
A solar farm in southern Spain powers a modular container mine consuming 500KW. The operation uses immersion cooling to prevent overheating in the hot climate.
- Energy Source: 10MW solar farm (500KW used for mining)
- Cooling Method: Immersion cooling with mineral oil
- Security: Unmarked containers to deter theft
HIVE Blockchain, Boden, Sweden
HIVE’s 30MW facility in a former military hangar houses 15,000+ mining rigs, primarily mining Ethereum. The site draws power from hydropower plants and constantly optimizes efficiency.
- Energy Source: Hydropower (Vattenfall)
- Machines: AMD RX580 GPUs dominate
- Innovation: Uses air twice for cooling
Italian Alps: Small-Scale Hydropower Mining
Alta Novella, a small hydropower plant in Borgo d’Anaunia, mines Bitcoin to diversify income. During low-energy periods, mining sustains operations.
- Capacity: 120–600KW (20% used for mining)
- Partnership: Alps Blockchain manages miners
- Impact: Helps cover maintenance costs
Bitfarms, Québec
Bitfarms operates six Canadian sites powered by hydropower (~$0.04/KWh). The Sherbrooke “Bunker” facility, a bomb-proof former distillery, aims for 3 EH/s by 2022.
- Advantage: Passive cooling in cold climates
- Hashrate Goal: 8 EH/s by year-end
- Sustainability: 99% green energy
BitCluster, Norilsk, Russia
Above the Arctic Circle, BitCluster’s 31MW mine repurposes a nickel plant. Extreme cold sometimes requires warming the machines.
- Location: Arctic industrial zone
- Challenge: -40°F temperatures
- Workforce: Locally trained technicians
FAQ
1. How does cold weather benefit crypto mining?
Cold climates reduce cooling costs, allowing passive air cooling and lower energy expenditures.
2. What renewable energy sources power mining farms?
Hydropower (Norway, Sweden), solar (Spain), and geothermal (Iceland) are common.
3. Why are miners secretive about their operations?
Security risks (theft) and regulatory uncertainty drive secrecy.
4. How do small mining farms stay profitable?
They leverage cheap local energy (e.g., hydropower) and innovative cooling methods.
5. What’s the future of sustainable crypto mining?
Expect more solar/hydro hybrids and heat-recycling projects like Kryptovault’s wood-drying initiative.
