Why cryptocurrency is bad for the environment?

Is bitcoin a threat to the environment ? Yes. In fact, every economic activity has an influence on the environment as a whole. However, why and how is bitcoin inferior to traditional payment methods?

This article gives a general overview of the environmental impact of cryptocurrencies and analyses possible environmental changes, some of which are currently occurring in the market.

What is Cryptocurrency?

Cryptocurrency, of which Bitcoin is the first and most well-known, is currency that only exists in digitally. It lives as pieces of information held on blockchains, which are systems of computers with a copy of the whole currency’s transaction ledger that is accessible, making cheating and forgery nearly difficult.

Cryptocurrency’s issue on the Environment

The issue with cryptocurrencies is how much energy they use. Most of the usage comes from symmetric encryption, which involves using computers to decode 64-digit sequences of illogical letters and numbers.

The first “miner” to figure out this conundrum receives fresh Bitcoins or other commodities in exchange, which can be worth tens of millions of dollars to the miner. This has resulted in an almost Gold Rush-like race for quicker, more potent processors, which has increased energy consumption.

Bitcoin mining just required an anticipated 121.36 terawatt-hours (TWh) in 2021, which is more energy than Argentina or nearly what vampire energy in the US uses per year.

What Effect Does Cryptocurrency Have on the Environment?

Some people are positive about cryptocurrencies like Bitcoin, but critics bring out a significant drawback: cryptocurrency mining consumes a considerable amount of energy. While there are other ways to verify digital currencies and create new currencies, the two most popular cryptocurrencies, Bitcoin and Ethereum, employ mining as their primary mechanism.

Consumption of Energy by Cryptocurrencies

The hash rate of the system and the power consumption by available commercial mining equipment may be used to determine the amount of energy needed for Bitcoin and cryptocurrency mining.

According to the Cambridge Bitcoin Electricity Consumption Index, the most widespread cryptocurrency system used more power at the point of manufacture than Belgium and Finland and consumed more than 85 Terawatt-hours (TWh) of electricity (0.38 percent of the world’s total electricity consumption) and 218 TWh (0.13 percent of the world’s total energy production).

According to energy usage through July 9, 2022, Ethereum, the foremost cryptocurrency system, is projected to require 62.77 Terawatt-hours of power year, which is similar to Switzerland’s power consumption. A typical Ethereum operation used 163 kilowatt-hours of energy, which is comparable to the amount used by a typical American family in 5.51 days.

The proof-of-stake agreement method was implemented by Ethereum researchers as a remedy, but it is still in the testing stage. 

Considering that rates and user acceptance continue to fluctuate, the amount of electricity used by bitcoin mining will probably change over time.

The motivation to start mining also rises as the price of the block reward does, making cryptocurrency mining a competitive process. Additional energy is used by bitcoin networks as a result of higher cryptocurrency values.

Why Energy Is Needed for Cryptocurrency Mining

The energy requirements of cryptocurrency mining are a benefit, not a flaw. The iterative procedure of confirming Bitcoin transactions without the involvement of banks or other reputable third parties is known as “mine.”

The system is dependent on the processing power of thousands of mining equipment, therefore the way the process in place procedure is built requires a lot of energy. Proof-of-work consensus-based cryptocurrency cryptographic protocols are kept secure by this reliance.

Why is mining cryptocurrency bad for the environment?

It is more difficult to determine the carbon impact of cryptocurrencies. Although the majority of the nations where cryptocurrencies are mined use fossil fuels as their main energy source, miners must look for the most affordable energy sources in order to stay profitable. That frequently entails using fresh renewable power installations.

Additionally, according to Digiconomist, the Bitcoin system produces around 73 million tons of carbon dioxide a year, which is comparable to Turkmenistan’s emissions. Ethereum mining is predicted to emit 35.4 billion tons of carbon, the very same quantity as New Zealand, based on statistics through July 9, 2022.

Could Energy Be Saved by Cryptocurrency Mining?

Large-scale bitcoin miners are frequently found in areas with inexpensive, dependable, and abundant electricity. However, it is not necessary for the production of new coins and executing cryptocurrency to be power.

An option for cryptocurrency that uses less computing power is the proof-of-stake (PoS) technique of approving transactions and creating new currencies.

However, the ability to run the crypto system and verify payments is predicated on the amount of bitcoin that a validation has “staked,” or committed not to trade or sell in exchange for their power.

Additional validation techniques are also being explored, including evidence of history, evidence of time passing, evidence of burn, and evidence of capacity.

While the creators of Ethereum have expressed their intention to do away with the proof-of-work algorithm, the Financial world has no such intention. Since Bitcoin is the most widely used cryptocurrency, mining and its high energy costs are probably here to remain.

Do all cryptocurrencies have a negative environmental impact?

The most common type of verification is proof of work, and it will probably continue to be important for the foreseeable future. However, not all cryptocurrencies use proof of work to generate them, therefore they don’t need as much processing energy or computing power to mine them as coins.

Although verification of blockchains is still required, new validation techniques have evolved that offer equal degrees of security via alternative verification techniques.

Proof of stake

With this verification method, miners may get mining privileges according to the amount of bitcoin they currently own by using the coins they already possess. To construct a validating node that can validate a payment, they start locking up their currency.

The blockchain picks a random validator node whenever a block of fresh data has to be validated. The block can be added to the blockchain if the validates approves it. They lose some of the money they wager if they try to upload a block of incorrect facts.

This method has been attacked for structural imbalances since people with a lot of coins receive the highest rewards, despite the fact that it does not suffer from the power use problems that affect proof of work.

It’s important to remember that buying the computer power required to mine via proof of work is similarly pricey. There are now more than 200 currencies that use evidence of stake, with Solana having the greatest market cap at $28.39 billion.

Proof of burn

Proof of burn is a combination of evidence of stake and proof of work. A certain quantity of bitcoin is burned by validators as part of proof-of-burn procedures, effectively removing those coins from existence.

When auditors do this, they purchase digital mining equipment that operates according to the number of coins burned; the more burned, the quicker you mine. Then, you may mine cryptocurrencies without having to use a lot of electricity.

This approach, which is still quite young, was developed especially to solve environmental issues related to mining for evidence of work. The result is that it hasn’t really taken off. The only cryptocurrency so far that makes use of this method is Slimcoin.

Proof of capacity

Proof of capacity uses the available space for storage on a mining device’s hard drive as verification rather than computing power or stake. The evidence of the ability mining method stores potential solutions using any free space on a mining device; hence, the more storage capabilities you have, the more answers you may store, increasing the likelihood that you have the right algorithmic answer.

Evidence of passing time

Another consensual method is proof of elapsed time, although this method is mostly employed in blockchain networks, as compared to public blockchains, which need access to see. It’s very random because this employs a lottery-style system to choose who gets to upgrade the blockchain.

Proof of work mining is still going strong despite improvements made in alternate methods of producing cryptocurrencies. The predicted monthly energy use of Bitcoin was 6.07 TWh in January 2020 and increased to 8.92 TWh in January 2021. Usage was at 10.95 TWh as of January 2022.

Finding a sustainable method to provide the electricity needed for the computational power that these miners utilize becomes the challenge with proof of work mining.

This entails shifting mining activities away from the US and toward nations with more sustainable energy production options. Theomou claims that once mining was outlawed in China, individuals travelled all the way to the US. It is concentrated, then. We require Bitcoin mining.

Out of concern about the environment, certain segments of the bitcoin business are abandoning proof of work. The second-most actively traded cryptocurrency, Ethereum, is planning to switch from proof of work to proof of stake.

There have also been initiatives to lower carbon emissions on a personal level. 250 people and companies have signed the Crypto Climate Agreement. These participants pledge to reach net zero carbon emissions by 2030 and, ultimately, to decarbonize the whole cryptocurrency sector by 2040.

However, Theomou says that because it is extremely unlikely that Bitcoin will see any significant changes, the cryptocurrency sector will never totally turn its attention away from Bitcoin. “It has never altered, which is the only reason it is as secure as it is.

And that’s what makes it so appealing to people—just being aware that things are as they are and always will be “He claims.

Theomou claims that the key to developing viable cryptocurrencies is knowledge. People frequently start out with Bitcoin since it is the most well-known cryptocurrency.

The more information people have about cryptocurrencies, the more alternatives they are aware of, and the easier it is for them to choose another cryptocurrency that is less damaging to the environment and doesn’t require proof of work in its use. The possibilities are there, but in order to even notice and make use of the greater options, you must become informed.
