Environmental concerns regarding the energy-intensive, proof-of-work (PoW) mechanism that Bitcoin (BTC) uses to produce new coins and verify transactions have been front and center lately. Debates regarding Bitcoin’s energy use particularly surged following a tweet sent out by Tesla CEO Elon Musk in May saying that his company would no longer accept Bitcoin payments due to the network’s “increasingly rapid use of fossil fuels.”Since then, a number of ways Bitcoin mining companies could go green have been discussed, many of which include using 100% renewable energy sources. For example, El Salvador president Nayib Bukele recently disclosed plans for a geothermal power company, letting Bitcoin miners use its facilities to ensure clean mining.
