Absent government intervention, the study estimated that the annual energy consumption of the bitcoin blockchain in China would peak in 2024 at 296.59 Twh (terawatt hour) – more than the total energy consumption of Italy or Saudi Arabia. That staggering demand for electricity would accordingly generate 130.50 million metric tons of carbon emission per year. That emission output would then account for approximately 5.41% of the emissions from all electricity generation in China.
According to CNBC, Beijing is aiming to reach peak carbon dioxide emissions by 2030 and carbon neutrality by 2060. Needless to say, the chances of that happening is bleak if this study is to believed. This is far from the first time that bitcoin mining’s adverse impact on the environment has been highlighted. But it puts the spotlight on bitcoin enthusiasts like Elon Musk, who’s also a champion of environmental causes. (Source: Nature Communications, CNBC.)
