Elon Musk, the CEO of Tesla, has suspended the purchase of their cars using bitcoin due to concerns about climate change. The news was announced in a tweet, after which the stocks of both Tesla and bitcoin immediately fell.
– We are concerned about the increasing use of fossil fuels for 'mining' bitcoin and transactions, especially coal, which has the worst emissions of all fuels – Musk said in the tweet.
Just two months earlier, in March, Tesla announced the acceptance of cryptocurrencies as a payment method for their vehicles, but that announcement faced backlash from numerous ecologists and investors.
Bitcoin’s Climate Controversies
Namely, bitcoin is created by so-called 'miners' who compete with each other using powerful computers to solve complex mathematical puzzles. In these processes, they 'produce' new monetary units. These energy-intensive processes rely on electricity generated from fossil fuels, particularly coal. The problem, therefore, is the lack of incentive to switch from cheap fossil fuels to more expensive renewable energy sources.
According to the BBC, more than 75 percent of bitcoin 'mining' in the world comes from China. The carbon footprint of cryptocurrencies is as large as one of the 10 largest Chinese cities, all due to the use of electricity produced from fossil fuels, primarily coal.
