Bitcoin mining to be banned in coal-heavy region of China

A Chinese province is cracking down on bitcoin mining operations in a bid to reduce energy consumption and emissions.

Bitcoin have been attracted to China for its cheap electricity, however its reliance on coal and other fossil fuels has raised questions about the network’s environmental impact. Current estimates put bitcoin’s energy requirements at around 130 terawatt-hours (TWh) annually, which would rank it in the top 30 electricity consumers worldwide if it were a country.

The Inner Mongolia Development and Reform Commission will force all new and existing cryptocurrency mines to close by April in order to meet its energy-saving targets.

A draft plan on the department’s website states a goal of cutting emissions and cutting energy consumption growth to about 5 million tons of standard coal. It is part of a broader pledge put forward by China to achieve carbon neutrality by 2060, and to begin reducing emissions in 2030. Bitcoin are increasingly looking to environmentally-friendly alternatives, with recent projections from the International Renewable Energy Agency finding that renewable energy sources are becoming more cost-efficient than fossil fuels.

The University of Cambridge’s 2020 Global Cryptoasset Benchmarking Study found that 76 per cent of cryptocurrency use electricity from renewable sources – up from 60 per cent in 2018.
