According to data sourced from Woocharts, as of December 29th, the share of clean energy integration in Bitcoin mining has reached an impressive 56.76%. This advancement in sustainable energy usage has shown a consistent upward trend since April 2021. The statistics reflect metrics established by the Cambridge Center for Alternative Finance, which carefully defines sustainability by examining the energy sources—such as wind, solar, hydro, and even nuclear energy—used in mining operations. A number of leading mining enterprises, including Riot Platforms and MARA Holdings, have bolstered their investments in renewable energy solutions, aligning with industry trends. Nevertheless, amid the ongoing global energy crisis, mining expenses have seen a noticeable increase. In light of these challenges, many companies are opting to utilize their remaining assets for Bitcoin acquisitions.
