The hash power of Bitcoin (BTC) network has jumped roughly 30% over the past 24 hours and up 42% in two days, suggesting a return of the cheap hydroelectric power miners in the (unofficial) Chinese mining capital of Sichuan. The sudden spike in mining activity could also mean the Bitcoin network is likely to produce another significant difficulty adjustment. The province of Sichuan is immersed in natural beauty and very tall mountains, and the vast terrain is perfect for mining and finding spices for Chinese cuisines. Sichuan is well known for being one of the largest concentrations of bitcoin miners because electrical costs are extremely cheap in the region. Data shows that miners using hydropower in Sichuan are paying between 0.065-0.075 yuan or $0.01 per kilowatt-hour. Sichuan captures roughly 30 billion kilowatts a year. Sichuan government’s is starting to soften their regulation of the "illegal mining operations", aiming instead "to bolster local economic development via the compliant use of hydropower.” According to Joule, the environmental impact of crypto mining accounts for 0.2% of global electricity consumption, and roughly the same CO2 as Las Vegas.
