Blockchain’s energy footprint is a hot debate. Proof‑of‑Work still consumes vast amounts of electricity, driving CO₂ emissions. Yet the industry is pivoting: Proof‑of‑Stake, layer‑2 roll‑ups, and renewable‑energy mining farms slash power use by 80‑90 %. Smart contracts can also track carbon credits, turning crypto into a tool for climate action. The question: how fast will the shift happen?
