10 things to know about CryptoPunks, the original NFTs

Bitcoin and similar blockchain-based currencies require huge amounts of power, predominantly generated from fossil fuels. The incoming mayor of New York City thinks cryptocurrency and blockchain technology are the future. Eric Adams has advocated to reshape the city into a crypto hotspot, with crypto being taught in schools.

He also plans to take his first three paychecks in bitcoin payment. The mayor of Miami announced in February that the city plans to accept tax payments in bitcoin and let employees draw their salary in the cryptocurrency. Crypto conferences like Bitcoin — billed as the biggest bitcoin event in history — have chosen Miami as their host city because the area has rolled out the red carpet for this industry.

Mining cryptocurrency is notoriously environmentally unfriendly, and in an era of rapid climate crisis, increasing the use of the technology could be hazardous. According to Digiconomist, a single bitcoin transaction uses the same amount of power that the average American household consumes in a month — which equals roughly a million times more in carbon emissions than a single credit card transaction. Such currencies require miners to compete to validate transactions on their blockchains, and that takes enormous, power-hungry servers.

Bitcoin mining uses energy predominantly generated from fossil fuels, which creates air pollution and carbon emissions, said Jones. Since mining crypto requires so much power, it is often situated near the cheapest, least-regulated sources of energy. The damages Jones and his colleagues pinpointed arise from increased pollutants generated from the burning of fossil fuels used to produce energy. Exposure to pollutants such as fine particulate matter has been linked to increased risk of premature death.

Last month, a group of 70 climate, economic and racial justice groups wrote a letter to Congress urging leaders to address the climate implications of cryptocurrency. The letter cites the extreme levels of carbon emissions, energy consumption and electronic waste generated by cryptocurrency usage, production and mining, especially the deeply energy-intensive proof of work process used by the two largest cryptocurrencies, bitcoin and ethereum.

Crypto-related mining already has an impact on local communities such as Seneca Lake, New York, and Limestone and Jonesborough in Tennessee, through environmental destruction, noise pollution and plummeting property value, the letter says.

Residents say that Seneca Lake has heated up so much due to the increased power demand that the lake feels like a hot tub. The power plant there is already increasing its carbon emissions, up almost tenfold in Texas has a problem too. Other places around the country are restarting coal-fired plants to power bitcoin mining.

In doing so, cryptocurrency is exacerbating decades of environmental racism and fueling climate chaos. This article is more than 2 months old. A banner with the logo of bitcoin is seen during the crypto-currency conference Bitcoin Convention in Miami, Florida, in June.
