Usage of non-renewable energy in Bitcoin mining increased by 13% in 2021

The Cambridge Centre for Alternative Finance (CCAF), which tracks the energy depletion of Bitcoin (BTC) mining, added the sources of vigor successful a large update connected Sept. 27. According to the data, the sustainable energy premix successful bitcoin mining declined by 13% successful 2021, compared to 2020.

Electricity from earthy state and atomic vigor saw the highest summation past year. Usage of energy from earthy state astir doubled from 12.83% successful 2020 to 22.92% past year. On the different hand, the stock of atomic vigor successful the Bitcoin mining energy premix much than doubled from 4.02% successful 2020 to 8.85% successful 2021.

Electricity produced from lipid accrued marginally to 1.47% from 1.21% the twelvemonth before. Coal remained the largest root of Bitcoin mining electricity, contempt its stock falling to 38.23% from 40.37% successful 2020.

As a effect of the expanding usage of fossil fuels, non-renewable vigor sources accounted for 71.47% of the energy consumed by Bitcoin mining successful 2021, the information indicates.

The usage of hydroelectricity saw the sharpest decline, dropping from 33.67% successful 2020 to 18.5% past year. However, hydropower remained the largest root of renewable vigor for Bitcoin mining.

Solar and upwind vigor usage accrued marginally from 1.83% and 5.19% successful 2020 to 2.73% and 6.02% successful 2021, respectively. The information shows that the stock of different non-renewable vigor sources grew to 1.23% from 0.46% successful 2020.

Overall, the stock of renewable vigor sources successful the Bitcoin mining energy premix declined from 41.15% successful 2020 to 28.48% successful 2021, according to the CCAF data.

The alteration successful renewable vigor usage, successful turn, pushed greenhouse state emissions from Bitcoin mining to an all-time precocious of 56.29 cardinal tonnes of c dioxide equivalent (MtCO₂e) successful 2021. It indicated an summation of implicit 63% from the 34.37 MtCO₂e emitted successful 2020.

Why the sustainability premix of bitcoin mining powerfulness deteriorated

According to Cambridge analysts, China’s prohibition connected Bitcoin mining imposed successful June 2021 played a relation successful the sustainability premix of BTC mining power. In a report, the analysts noted that earlier the mining ban, miners successful China seasonally migrated wrong the country.

During the rainy season, erstwhile h2o levels rose, miners moved to regions with abundant inexpensive hydropower. During the adust seasons, miners moved to thermal powerfulness plants erstwhile the h2o levels fell. The study noted:

“…the Chinese government’s prohibition connected cryptocurrency mining and the resulting displacement successful Bitcoin mining enactment to different countries negatively impacted Bitcoin’s biology footprint.”

But the interaction of China’s mining prohibition was constricted since China’s stock of mining powerfulness fell to zero, irrespective of the little spike successful September 2021.

However, arsenic the miners relocated to different countries aft the Chinese mining ban, the relocation portion impacted the sustainability premix of Bitcoin mining electricity.

For instance, successful countries similar Kazakhstan, wherever respective Chinese miners relocated, energy is chiefly produced from fossil fuels. Sustainable vigor sources lone relationship for 11% of the energy premix successful the country.

But successful Sweden, which lone accounts for a minuscule stock of Bitcoin mining, 98% of energy is generated from renewable resources. Therefore, the biology footprint of Bitcoin mining depends connected the mining hashrate successful each country.
