Bitcoin production relies on extensive computational power and significant electricity consumption, making hydropower stations key beneficiaries. Miners strategically choose locations based on operational costs—primarily electricity.
The Energy-Intensive Nature of Bitcoin Mining
Bitcoin mining requires solving complex mathematical puzzles through high-performance computers, consuming vast amounts of electricity. Regions with abundant renewable energy, like Sichuan’s hydropower stations, attract miners due to lower costs. During rainy seasons, surplus electricity powers mining farms, while dry seasons force relocation to areas like Xinjiang or Inner Mongolia.
Key Stats:
- Global Bitcoin mining consumes ~60,000 kW, equivalent to a midsize hydropower station in China.
- Sichuan alone contributes ~5% of worldwide Bitcoin production, leveraging cheap hydropower.
The Mining Process: A Technical Breakdown
- Transaction Verification: Miners validate transactions by solving cryptographic hashes.
- Block Creation: Successfully solved blocks (1MB every 10 minutes) are added to the blockchain.
- Reward System: Miners earn 12.5 BTC per block (halved every 4 years) plus transaction fees.

Challenges and Economic Impact
- Rising Competition: Increased mining difficulty reduces individual rewards.
- Regulatory Uncertainty: Policies vary by region, affecting operational stability.
Case Study: In Sichuan’s Kangding city, mining spurred local economies—even delivery personnel recognize mining hardware models.
