Bitcoin mining has transformed significantly:

Sustainability Trends:

• Over 55% renewable energy usage globally
• Stranded energy and flare gas capture growing
• Heat recycling (mining rigs heating buildings/pools)

Profitability Factors:

• Electricity cost is still #1 factor
• ASIC efficiency improvements (J/TH keeps dropping)
• Post-halving economics favor efficient operators
• Mining pools consolidation continues

For home miners: Unless you have very cheap electricity (< $0.05/kWh), solo mining is rarely profitable. Consider joining a mining pool or looking into cloud mining alternatives.
