TechFlow reports on December 29 that, according to data from Woocharts, the share of clean or sustainable energy used in mining currently stands at 56.76%. Since April 2021, BTC's use of clean energy has been steadily increasing. The platform uses the Cambridge Centre for Alternative Finance's definition of sustainability to measure clean energy usage, with relevant metrics based on the proportion of crypto-mining operations powered by wind, solar, hydro, and even nuclear energy.
In recent years, Bitcoin mining firms such as Riot Platforms and MARA Holdings have increased their investments in clean energy. However, amid the ongoing global energy crisis, mining costs continue to rise. To cope with this situation, most mining companies are using their surplus capital to purchase Bitcoin.
