Newer mining rigs (e.g., Bitmain S21) improve energy efficiency by 20%-30% over S19 models. Renewable energy adoption is rising, with ~30% of Bitcoin mining using renewables in 2023, reducing reliance on costly grids. Trend Analysis: By 2025-2026, more efficient ASICs and relocation to energy-rich regions (e.g., Middle East, Nordics) could lower costs. ROI Outlook: Moderately positive in the medium term, but high upfront costs for new hardware may extend payback periods to 18-24 months.
