One piece of good news for Bitcoin investors this week is the release of a new study claiming that the total carbon footprint from the extremely energy intensive activity of Bitcoin mining might be less than one third of previous estimates. Bitcoin miners assemble large arrays of energy hungry computer processors and memory banks that work through complex algorithms to ‘mine’ new Bitcoins. Danish researchers, Susanne Köhler and Massimo Pizzol estimated total carbon emissions from all Bitcoin mining at 17.29 megatonnes per year. Previous estimates have been as high as 63 megatonnes per year. The researchers also identified the world’s Bitcoin mining hotspots. Top 5 Bitcoin mining regions 1 Inner Mongolia (China) 2 Xinjiang (China) 3 Alberta (Canada) 4 Russia 5 Washington state (USA) How much energy does Bitcoin mining consume? The computing power required to solve a Bitcoin algorithm and create a new Bitcoin has increased four times over since 2018, according to research released in June 2019. The total carbon emissions from bitcoin mining globally exceed those of a small country or medium sized US state such as Kansas said the researchers, led by Christian Stoll from the University of Munich and Massachusetts Institute of Technology. With annual emissions of around 22 – 23 megatons of CO2, Bitcoin produces around the same amount of carbon as Jordan and Sri Lanka. The researchers said adding in all the other cyptocurrencies would double the total carbon footprint of global crypto activity. Christian Stoll said more attention needs to be given to the costs of Bitcoin and cryptocurrency mining.
