Bitcoin miners are increasingly turning to renewable energy to offset costs as the hash rate has fallen below the critical $40 threshold for profitability.
According to Hashrate Index, a mining data provider, the Bitcoin hash rate is around $38,56 per petahash per second per day (PH/s/day), down from around $55 per PH/s/day in Q3 2025.
That’s why companies like Sangha Renewables are using more renewable energy in their operations. The miner recently launched a 20-megawatt (MW) solar power complex in Texas.
Thanks to a deregulated electricity market, abundant renewable resources, and flexible grid infrastructure, Texas has become one of the world’s leading regions for Bitcoin mining. Most mining companies in the state participate in demand response programs, which allow them to suspend operations during periods of peak power demand in exchange for grid credits or compensation.
Phoenix Group also announced in November that it had begun mining using a 30-megawatt hydroelectric power plant in Ethiopia, and in September, Canaan and Soluna partnered to create a wind-powered mining facility. Canaan is also implementing an innovative mining rig that dynamically adjusts energy consumption using artificial intelligence and balances electrical loads.
Overall, Bitcoin miners are going through tough times – the post-halving reward reduction has driven their profits to their lowest level ever.
However, the general hashrate Bitcoin’s mining surplus, which reflects the computing power that powers the protocol, is at an all-time high. This increase means miners must increase their computing power to remain competitive.
