Annual carbon footprint of PoW coins measured in terawatt-hours (TWh) of electricity consumption: 1. Bitcoin (BTC): 114 TWh With a market cap just shy of $1 trillion, Bitcoin’s carbon footprint of 54 million metric tonnes of carbon dioxide is comparable to that of Singapore. The footprint of a single mined Bitcoin is estimated at 150 tonnes of carbon, which is around six times the pollution from the equivalent amount of mined gold, according to Digiconomist. Some sources, including the Cambridge Bitcoin Electricity Consumption Index, say that the world’s largest cryptocurrency uses almost 150 TWh per year — more than the whole of Malaysia. Put another way, a single Bitcoin transaction needs more power than the average United States household consumes in a month. 2. Ethereum (ETH): 44 TWh Ethereum has been giving Bitcoin a run for its money, and its energy addiction has risen just as fast. Its carbon footprint is about 22 million metric tonnes, comparable to that of Lebanon. And its electricity use rivals that of Hong Kong. The Ethereum network plans to switch over from PoW to a more efficient proof-of-stake system later in 2021. As of now though, Bitcoin and Ethereum together make up almost 90 percent of the annual electricity usage of all proof-of-work coins, so the rest comprise a small share. 3. Dogecoin (DOGE): 7.8 TWh Elon Musk’s favourite meme crypto has surged in value since the beginning of the year. Its market cap rose above $75bn recently before giving back some gains, catapulting energy usage from the cute coin into third place, from tenth place in March 2020. With the electricity usage of Zimbabwe, Dogecoin was originally designed as a joke. 4. Bitcoin Cash (CSH): 3.4 TWh This cryptocurrency forked off of Bitcoin, spinning off as its own token in 2017. It still uses the same secure hash algorithm (SHA-256) as its parent. With a market cap currently hovering around $23bn, its electricity usage is about the same as Nicaragua — a country that powers an economy producing $11bn of goods and services per year. This means BITCOIN CASH uses just under 3% of electricity than Bitcoin. https://www.google.com/amp/s/www.aljazeera.com/amp/economy/2021/5/13/after-musk-bitcoin-u-turn-which-coins-are-more-climate-friendly
