Various Proposals for “Green” BTC Miners; Solana, Cardano, and KangaMoon Keep Carbon Emissions Low"
however There are growing concerns around environmentally friendly energy in Bitcoin mining, according to certain reports. These concerns stem from the large carbon emissions associated with Bitcoin's proof-of-work (PoW) architecture which is estimated to produce around 85 million carbon dioxide annually. To address this, a partnership between PayPal's blockchain research group, Energy Web, and DMG Blockchain Solutions has been established. They plan to incentivize miners to use low-carbon energy sources through cryptoeconomic rewards. On the other hand, there are top altcoins that naturally maintain low carbon emissions. They include Solana (SOL), Cardano (ADA) and KangaMoon (KANG).
