The vast amount of energy consumed by Bitcoin mining has increased in the past year. Although the value is low Cryptocurrency After surpassing $ 50,000, the energy used to create it has continued to rise during its epic ascent.
Energy use has risen to the equivalent of Argentina’s annual carbon footprint, according to an index Cambridge Bitcoin For electricity consumption, a tool from Cambridge University researchers that measures the currency’s energy use.
It is possible that recent interest from the major Wall Street institutions culminated in the appreciation of the currency and endorsement by Elon Musk helped push it to its highest levels.
While the recent decline has affected Musk’s fortune, Bitcoin is also a threat to the company’s mission towards a zero-emissions future and poses serious questions for governments looking to reduce their carbon footprints.
Bitcoin mining is an energy-intensive process, and mining involves solving complex mathematical problems in order to create new Bitcoins, and the miners are rewarded with Bitcoin.
Earlier in the relatively short history of Bitcoin, one could mine the currency with a regular computer.
But the way the Bitcoin mining process was established means that there is a limited number of Bitcoins that can be mined, up to 21 million.
The more mining, the more difficult the algorithms must be solved to obtain Bitcoin. The regular computer can no longer mine the coin after it has been mined More than 18.5 million Bitcoins.
And theInstead, the mining process requires special computing equipment that can handle the intense processing power required to obtain Bitcoin, andThese special devices require a lot of electricity to operate.
Historically, the amount of electricity used to mine the currency has been more than the electricity used by entire countries, such as Ireland, meaning that there are huge amounts of electricity used only for Bitcoin.
Proponents of the currency say: Mining is increasingly done using electricity from renewable sources as this type of energy becomes cheaper, and the energy used is much less than other energy uses that are more wasteful.
Energy wasted by connected but inactive home appliances in the US alone could occupy Bitcoin mining for 1.8 years, according to an index. Cambridge Bitcoin To consume electricity.
According to the index, China has the largest number of Bitcoin mining operations of any country so far, and while the country has been slowly moving toward renewable energy, about two-thirds of its electricity comes from coal.
Given that there is no government agency or organization that officially tracks where mining is located and what type of electricity miners use, there is no way to know if miners use electricity fueled by renewable energy or fossil fuels.
And mining rigs can move from one place to another depending on where the energy is cheaper, which makes mining difficult to track.
The Cambridge Center estimates that Bitcoin’s annual electricity consumption is estimated at 115 TWhAccording to the site, one Bitcoin transaction has the same carbon footprint as 680,000 Visa transactions or 5,110 hours of watching YouTube.
And a 2018 paper from the Oak Ridge Institute in Ohio found that mining one dollar of Bitcoin consumes 4.7 kilowatts of energy, more than twice the amount of energy needed to mine copper, gold and platinum worth one dollar.
Another study from the United Kingdom published last year stated that computer power required for mining quadrupled in 2019 compared to the previous year, and that mining had an impact on prices in some energy and utility markets.
As Bitcoin continues to dominate as the largest cryptocurrency, and with support from established companies and investment banks, the environmental impact of the currency is likely to grow.
