Bitcoin: Bad for Environment

Some could be interested in the promise of decentralization, open access, very little control, and anonymity, plus the opportunity to make money from transactions by ‘gambling’ with market rules. Others, though, can’t help but look away from the Bitcoin algorithm and its demand for computer resources for transaction validation. But just how toxic is Bitcoin? How harmful to the environment are Bitcoins? Here’s a short introduction to Bitcoin from the standpoint of sustainability. Perfect for shedding some light on how Bitcoin works for the first time.

Why Mining Energy Requires?

The competitive nature of proof-of-work blockchains is responsible for these exorbitant energy expenditures. Instead of maintaining account balances in a single database, a distributed network of mines, driven by block rewards, records bitcoin transactions. These specialized computers run a computer race to record new blocks, which may resolve only cryptographic riddles. Advocates of cryptocurrency argue that this system has several benefits over centralized currencies since it does not rely on a trusted intermediary or a single failure point. However, numerous energy-intensive calculations are for mining riddles.

The BBC reported in 2021 that Bitcoin, the most well-recognized cryptocurrency network, requires 121 Terawatt-hours of power per year, more than the whole country of Argentina. The Ethereum network uses as much electricity as the entire nation of Qatar, according to Digiconomist, a cryptocurrency analysis website. One of the environmentalists’ key concerns is that mining tends to grow less efficiently as cryptocurrency prices rise. Using Bitcoin, mathematical problems to produce blocks become more challenging as the price increases, but transaction performance remains constant. It means that the network uses more power and energy over time to perform duplicate transactions.

Environmental Effect and Bitcoin

In short, Bitcoin is the digital currency developed in 2009 following the ideas of the pseudonym Satoshi Nakamoto in a white paper. It has its website – which is secure for visitors to access – where you may start Bitcoin by purchasing a crypto-currency wallet. It promises cheaper transaction charges than standard online payment systems – like MoneyGram, Transferwise, and Western Union – and, unlike government-issued currencies, operates through the use of blockchain technology by a decentralized authority.

Although its value has grown over the years, Bitcoin has steadily identified practical issues and inefficiencies. From lack of consumer protection to promoting crimes such as money laundering, tax fraud, drug and weapons purchases, or child pornography. Instead, we want to understand why Bitcoin is harmful to the environment. To do so, we have to start by looking at Bitcoin’s underlying technology – blockchain – which does energy-intensive cryptocurrency.

Digital Currencies and Fossil Fuels

All this combined to link cryptocurrency with fossil fuels in a manner that many investors still struggle to recognize. Researchers at the University of Cambridge say that about 65 percent of bitcoin mining is in China, a country that uses carbon to burn most of its power. 2

Coal and other fossil fuels are presently the world’s primary energy source for bitcoin mining and other sectors. Burning coal, however, contributes significantly to climate change through the carbon dioxide produced by the process. According to a CNBC study, roughly 35.95 million tonnes of carbon dioxide emissions are generated a year by bitcoin mining—nearly the same amount as New Zealand.

Consumption of Energy

The Bitcoin public directory is decentralized, which implies that no one authority controls it. Instead, Bitcoin is updating routinely by a network of computers run by so-called ‘miners’ worldwide. These miners utilize proprietary computers to solve complicated arithmetic problems to allow transactions – the only method to mint new bitcoins – to take over, in exchange for a tiny portion of the transactions made by Bitcoins. During recent years, with the price of Bitcoin hitting new heights (and lows, as happened lately with Elon Musk’s Bitcoin Tweet), the attraction of Bitcoin mining has led to an enormous increase in overall power usage in the Bitcoin network.

As mining may generate a substantial stream of money, every Bitcoin transaction they assist in ending up with has increased the number of people – dubbed miners – ready to operate power-hungry devices. The Bitcoin Network is, therefore, currently more energy-consuming than many countries. Bitcoin has a similar environmental effect (118,9TWh/ year) on the Digiconomist Bitcoin energy consumption index compared to the energy consumption of countries like the Netherlands (117,1 TWh/year) or Pakistan (125,9TWh/year).

Defend Mining Cryptocurrency Advocates

Supporters have played down the energy usage of cryptocurrencies, saying that mining companies tend to focus on locations where excess renewable energy is available. A 2019 analysis by CoinShares, a research company based in pro-crypto-currency, estimates that 74.1% of the electricity supplies to the Bitcoin network come from renewable sources, making Bitcoin mining “more renewable than most other major business around the globe.” Those assertions are that bitcoin miners are not in one place to hunt for extra energy. According to CoinDesk, some oil firms explore ways to supply gas flares to mining plants, which would otherwise be energy squandered. Some Chinese mining companies shift from one province to the next for the lowest point, encouraging low-cost renewable suppliers.

Bitcoin’s renewable energy use calculations are contentious and often controversial. For example, the Cambridge Center for Alternative Funding research revealed that renewable energy accounts for just 39 percent of bitcoin mining. Although renewable energy usage is hopeful, the network makes a net contributor to carbon emissions.

Other Cryptocurrency Mining Environmental Impact

Besides energy usage, bitcoin mining also creates a substantial quantity of electronic trash when outdated technology. It applies in particular to application-specific integrated circuits, which specialize in mining the most popular cryptocurrencies. Unlike other computer hardware, they cannot re-use these circuits for any other purpose, and they rapidly become outdated. The Bitcoin network creates between 8 and 12 thousand tonnes of electronic trash each year, according to Digiconomist.
