What Percentage of PoW Mining Currently Uses Renewable Energy?

Estimates on the percentage of Proof-of-Work (PoW) mining powered by renewable energy vary widely and are a subject of ongoing debate. Some reports suggest the figure could be over 50%, citing miners' attraction to cheap sources of power like hydropower.

However, other studies provide lower estimates, and precise data is difficult to obtain due to the decentralized and often private nature of mining operations. The Cambridge Bitcoin Electricity Consumption Index is a key resource, but even it highlights the challenges in getting definitive figures.
