Bitcoin miners are increasingly adopting renewable energy sources as profitability declines, with hash prices falling below $40 per PH/s/day. This shift comes as the global hashrate reaches 1,000 PH/s, driven by post-halving reward reductions and escalating energy costs. Major players like Sangha Renewables and Phoenix Group are leading the charge with large-scale green mining operations, while Canaan is developing adaptive ASICs to enhance energy efficiency. As energy prices become a critical factor for survival, miners are focusing on cost control and sustainability.
