The Dangerous Impact of Cryptocurrency Mining on the Environment

More and more people are getting into cryptocurrency mining, but how does this process affect the environment?

The University of New Mexico researchers Andrew Goodkind (asst. professor, Economics), Benjamin Jones (asst. professor, Economics) and Robert Berrens (professor, Economics) are using existing data on the energy used by cryptocurrency and a set of economic valuation techniques to determine just how much cryptocurrency mining costs. “Our expertise is in estimating the monetary damages, due to health and environmental impacts, of different economics activities and sectors,” Berrens clarified. “For example, it is common for economists to study the impacts from energy use connected to production and consumption patterns in agriculture, or with automobile production and use.

According to researchers from The University of New Mexico who are looking into the environmental impact of crypto mining, there are several areas which are greatly affected by this operation:

“What is most striking about this research is that it shows that the health and environmental costs of cryptocurrency mining are substantial; larger perhaps than most people realized,” said Benjamin Jones, UNM researcher.

Their climate damage estimates are based on carbon dioxide emissions resulting from electricity production.

In China, climate change is about 89% because of cryptodamages, while the rest of 11% is because of human health effects. In the United States, nearly 60% of cryptodamages impact the climate, while 40% affect health.

This is because emissions resulting from electricity production are higher in China than in the United States. Cryptocurrency mining in China greatly influences the rates of premature mortality. According to the researchers, every 50,000 Bitcoins mined in China result in 12 additional deaths from exposure to particulate matter.

A New Scientist research shows that Bitcoin mining generates carbon emissions as the entire country of Estonia, with Chinese miners having a contribution of 47%. The Cambridge Bitcoin Electricity Consumption Index (CBECI) found out this year that Bitcoin’s power consumption surpassed that of Switzerland.

The mining hardware also requires cool systems in order to prevent overheating while computing such complex algorithms. This consumes additional energy, which was not included in this study, meaning that even more energy and thus more damages are being produced.

Cryptocurrency Mining and Carbon Emissions

The study revealed that in 2018, the entire network had an electric consumption of 31.3 terawatt hours, which generated 17.3 megatons of carbon dioxide.

China is the largest producer and consumer of coal energy in the world, having mines in the Xinjiang and Inner Mongolian regions. Coal energy sources have 30% cheaper energy than those using renewable energy. When comparing mined cryptos with renewable energy sources in Canada, the same mined crypto in China would have a quadruple amount of CO2 emissions.

A CoinShares research report calculated that 77.6% of crypto-mining operations use electricity from renewable resources, while the rest of the 22.4% rely on fossil and nuclear producers.

Many extensive cryptocurrency mining facilities are located in regions such as the Pacific Northwest, Upstate New York, Northern Scandinavia, Iceland, and Georgia, where mostly renewable energy sources are used.

Conclusion

As we can notice, renewable energy production models have less of an impact on the environment. We can only hope that miners and mining farms will try to shift towards using more renewable energy than those based on fossil fuels to lessen the negative effects of carbon emissions. Also, if cryptos change from their PoW protocol to PoS, which is less memory intensive than the former, this could drastically reduce energy consumption.
