Power plants powered by coal represent an important contributor to climate change. Thus, over time, the network will consume more computing power and energy to handle the same number of transactions.Īround 65% of bitcoin mining takes place in China, a country that generates most of its electricity by burning coal.Ĭoal and other fossil fuels represent a main source of electricity worldwide, both for cryptocurrency mining operations and other industries. In the case of bitcoin, the mathematical puzzles to create blocks get more difficult as its price goes up, but transaction throughput remains constant. One main concern among environmentalists is that mining tends to become less efficient as the price of cryptocurrencies continues to increase. Nonetheless, the puzzles for mining require many energy-intensive computations.īitcoin has the most popular cryptocurrency network, and it uses 121 Terawatt-hours of electricity every year. Notably, it doesn’t rely on any trusted intermediary or single point of failure. The only option to create a new block is to solve cryptographic puzzles.Ĭryptocurrency advocates think that the system offers numerous benefits over centralized currencies. These specialized computers take part in a computational race to record new blocks. Instead of storing account balances in a central database, cryptocurrency transactions are recorded by a distributed network of miners, boosted by block rewards. These huge energy costs are due to the competitive nature of proof-of-work blockchains.

Many environmentalists have raised concerns about the energy consumption of cryptocurrency mining, which may cause increased carbon emissions as well as climate change. Bitcoin and most cryptocurrencies, in general, consume a lot of electricity.

His tweet triggered a debate on bitcoin’s environmental impact. The price of bitcoin declined after Tesla CEO Elon Musk announced his company would no longer be accepting it as a form of payment due to its ties to fossil fuels.
