In places such as Kazakhstan, the growing crypto mining industry relies primarily on fossil fuels, which generated close to 90% of the country’s electricity last year
Nur-Sultan, July 19 - Neftegaz.RU.
Chinese bitcoin mining has almost entirely ceased since the government restricted cryptocurrency use in May, meaning much of this activity has moved elsewhere – including to Kazakhstan, where fossil fuels
, including coal, produce more than 90% of the nation’s electricity supply, New Scientistanalysed.
Bitcoin relies on a network of computers known as miners that solve mathematical problems to secure the currency, consuming vast amounts of electricity in the process.
Data from the Cambridge Centre for Alternative Finance (CCAF) shows that the previously rapid investment in new bitcoin mining
plants stopped in China from September 2019 to April 2021 in anticipation of the ban.
China’s share of global bitcoin mining power declined from 75.5% to 46% over the period, while the existing miners remained static in size and waited for news.
During the same period the global mining share of Kazakhstan rose from just 1.4% to 8.2%, catapulting it to third place after the US.
Bitcoin has faced growing criticism for its impact on climate change
and a rise in Kazakhstan mining is likely to further that narrative as the country is heavily reliant on fossil fuels.
was the world’s 9th
largest producer of coal
in 2018, according to IEA
In that same year, 70% of its electricity was derived from coal power, and 20% from natural gas
made up only 1.4% of the country’s energy supply.
The Chinese ban has shaken up the entire sector, with CCAF data showing that more than half of miners worldwide have stopped operating.
The entire network was estimated to be using 132 terawatt-hours of energy in mid May but this plummeted to 59 TWh in early July.
