Odaily Planet Daily News: The Bitcoin mining ecosystem is rapidly developing, and its utilization of clean energy has made significant progress. According to data from Woocharts, the proportion of clean or sustainable energy used in mining currently stands at 56.76%. Since April 2021, the usage of clean energy for BTC has been steadily increasing. The platform measures its clean energy usage based on the definition of sustainability from the Cambridge Centre for Alternative Finance, with relevant indicators depending on the share of cryptocurrency mining operations powered by wind, solar, hydro, and even nuclear energy. In recent years, Bitcoin mining companies such as Riot Platforms and MARA Holdings have increased their investments in clean energy. However, against the backdrop of the current global energy crisis, mining costs continue to rise. To cope with this situation, most mining companies are using their remaining capital to purchase Bitcoin.
