As the earth warms due to greenhouse gas emissions, mankind may face a climate crisis by the end of the century. Coal and natural gas-based dirty energy has become humanity's biggest nemesis, with governments and corporations vowing to eliminate it forever. However, the decentralized cryptocurrency business was able to avoid making obligations, causing widespread concern. An unseen army of digital coin creators consumes more power than whole countries, and skeptics fear that miners will destroy the earth. In actuality, the bitcoin business is considerably more concerned about the environment than foreign banks and companies.
Dirty Money
Humanity is becoming increasingly concerned about the challenge of lowering harmful emissions into the environment in order to counteract global warming. The global average yearly temperature is rising, and many countries are already suffering from the consequences of climate change. In the world, a true fight has erupted against the planet's polluters - oil firms, coal industries, and airlines. The focus of public criticism in recent years has shifted to bitcoin producers, or miners.
Mining digital money is a tremendously energy-intensive operation. Thousands of powerful computers compete against one another to solve a cryptographic puzzle for each transaction. Computing devices compete to be the first to decode the code and confirm the transaction, which results in the creation of a new coin in the network and a reward for the miner. Because a request to confirm a transaction might arrive at any moment, computers (also known as mining farms) are linked to the network 24 hours a day.
To date, the Bitcoin network consumes about 0.5 percent of all energy used on the planet. Many countries' energy systems are still reliant on "dirty" fuels like gas and coal, both of which emit carbon dioxide when used. For those who would rather not go into the specifics of mining power usage, excessive energy consumption entails huge environmental impact by default.
"Bitcoin mining needs so much computer power that it consumes more energy than whole countries." "Suppressing the creation of ecologically hazardous cryptocurrencies is one of the easiest and least destructive things we can do to fight the climate catastrophe," stated renowned US Senator Elizabeth Warren in June 2021. The world's largest bitcoin network has overtaken numerous nations in terms of energy use, including Malaysia, Sweden, Norway, and Belarus.

Furthermore, as the crypto market rises, so does the amount of global processing power utilized in the process of mining digital currency. Miners who want to make money are increasingly showing up on the network. As a result, more power is consumed on mining currencies every year. Furthermore, the more miners there are, the more difficult it is to obtain a coin; for this reason, the network has introduced a particular "difficulty" parameter. It illustrates how much computational power a miner needs to generate money. Participants in the cryptocurrency market are seeking for ever more powerful (and voracious) hardware. Because there were fewer miners ten years ago, it was feasible to mine bitcoins on a fixed computer, but it will currently take nearly 13 years to mine them on a PC.
The United States is not the only country worried about the environmental impact of mining. In China, kritovalyut production was recently deemed illegal, and the authorities described the ban on mining as a result of the country's "inconsistency green goals" to cut carbon emissions. The Green Agenda has become a global movement, and support for it has a significant impact on not only governments' but also businessmen's and businesses' public image. Elon Musk, the creator of the auto company Tesla and a well-known proponent of cryptocurrencies, allowed consumers to buy electric automobiles using bitcoins in March 2021. However, in May, the billionaire dropped out of the project, citing the negative impact of bitcoin on the environment.
Greenpeace, a global environmental group, ceased taking bitcoin payments in the same month of 2021 owing to their carbon impact. Even before that, the media had begun to cover the subject. The media referenced research that projected global catastrophes as a result of cryptocurrency. For example, in 2017, the creator of a ZeroHedge economic blog predicted that mining will absorb all of the world's energy by 2020. (the article has already been removed from the site). In 2018, Hawaiian scientists released a study in the journal Nature claiming that the Bitcoin network can "heat the Earth by two degrees Celsius" on its own.
Pure Statistics
The global need for mining electricity is steadily increasing. According to University of Cambridge experts, the bitcoin network would require 119.65 terawatt-hours of power in 2021, despite the fact that this amount was just 29 terawatt-hours in 2018. If Bitcoin were a nation, it would rank 32nd in yearly power usage, trailing only Argentina (121.8 terawatt-hours) and the Netherlands (111 terawatt-hours).
According to Forex Suggest, the Bitcoin network produced 59.9 million tonnes of carbon dioxide emissions in 2020, accounting for 0.16 percent of world emissions. Right present, there isn't much new information on the carbon impact of cryptocurrencies. This is owing to China, the world's top cryptocurrency producer, imposing a mining ban in May. The act sparked a large "exodus" of miners who, fearful of losing their source of income, fled to neighboring nations in pursuit of cheap power and more flexible regulatory norms.
The worldwide share of Chinese miners was 46 percent in April 2021, but it sank to zero the following month. The country gets 85 percent of its energy from "dirty" fossil resources, mostly coal. As a result, when China possessed nearly half of the world's computing power, mining's carbon footprint was far greater than it is now.
According to experts, the migration of hundreds of thousands of Chinese miners also implies that they would discard antiquated equipment that has long since expired. According to Alex Brammer, a member of the Luxor Mining pool, mining's energy efficiency will improve globally after they modernize their machinery. Modern mining equipment (ASIC devices) have far more processing capability than older models (video cards) while using far less energy.
Mining, on the other hand, isn't the only technique to create bitcoins. Mining is the process of extracting currencies using the Proof-of-Work (PoW) method in the crypto world. Stacking, which employs the Proof-of-Stake (PoS) algorithm, is another popular mining method. It does not need a lot of CPU resources and is basically eco-friendly. The health of the blockchain is assured by digital token holders, who are compensated for doing so. The Cardano cryptocurrency network, for example, is based on staking and is sixth in the world in terms of capitalization.
In 2020, Ethereum (or ether), the second most costly cryptocurrency, announced the switch to the PoS algorithm. The major purpose of the reform, according to the corporation, is to restore the environment; the designers guaranteed that following the blockchain ether shift, it will consume 99.95 percent less power.
Ethereum, which is powered by conventional mining, consumes roughly 45 gigawatt hours per year and emits 16.8 tons of CO2. Vitalik Buterin, the company's founder, stated in August that the network renovation should be finished by the end of 2021.
Quality is more important than quantity
When it comes to the environmental impact of conventional mining, it's important to focus on the sources of energy rather than the amount of energy utilized. The crypto business has an edge over other industries in that digital currency may be mined from anywhere. Energy must be produced in close proximity to conventional industries in order for them to function. Cryptocurrency mining, on the other hand, has no such limitations, and miners may employ energy sources that aren't available to most other sectors. Many nations create coins with zero carbon emissions utilizing renewable resources like as nuclear, sun, wind, water, and heat from subsurface sources (geothermal energy).
Renewable energy is also becoming more appealing to miners due to the fact that it is becoming more affordable. The development of the most popular "clean" energy sources is currently either equivalent to or less expensive than coal and gas, according to investment firm Lazard's 2020 annual report. Users' spending on solar PV systems, for example, plummeted by 85 percent between 2010 and 2020, while onshore wind farm power declined by 56 percent.
Iceland, for example, is one of the world's greatest mining hubs, yet its electricity is virtually entirely produced in an ecologically responsible manner, using hydropower and geothermal plants. A similar situation exists in Norway, where net energy provides 98 percent of the energy. Because of their developed green energy, the Scandinavian countries have become attractive locations for miners migrating in recent years.
El Salvador, which has recognized bitcoin as a national currency, has opted to take use of the country's unique geography and mine using the volcano's energy. Engineers developed a new well with a capacity of 95 megawatts and began construction on a mining center near the volcano for this reason. President Nayib Bukele described the energy generated in this method as "affordable, clean, and renewable." The device was put to the test in October 2021, and the authorities were able to generate 0.00599179 bitcoin worth $269.
According to a global survey conducted by the non-profit Bitcoin Mining Council in the third quarter of 2021, Bitcoin utilised 57.7% renewable energy by September. This percentage is fast increasing due to the influx of Chinese miners and the low cost of clean energy; at the end of March, it was just 36.8%. Katie Wood, the founder of the ARK Invest investing firm (which according to American Forbes is one of the fastest growing and most efficient in the world), believes that the digital currency will benefit the globe more than any government subsidy or initiative to build sustainable energy sources.
Eco-revolution
The bitcoin world has been transformed by China's mining ban. The topography of mining has shifted dramatically in the last six months, according to a research released in July by the University of Cambridge. By the conclusion of the summer, a new trio of currency mining leaders had emerged: The United States had 35.4 percent of world computer power, Kazakhstan had 18.1 percent, and Russia had 11.2 percent.
The relocation of miners, according to experts, has helped the bitcoin network become greener. To save money, miners flocked to areas with the cheapest energy sources, which were mostly renewable at the time.
Whit Gibbs, the founder of the American crypto startup Compass, stated in July that owing to Chinese miners, retail sales of equipment and hosting at his company nearly quadrupled in a month. In the same business, Fred Thiel of Marathon Digital believes that by the end of 2022, the worldwide share of US computer power will have risen to 40%.
Texas has become the most popular state in the United States among currency miners. Wind energy production is strongly sponsored by local governments, and power is cheaper there than in other regions of the country. The state has 150 wind turbines with a total capacity of about 30 thousand megawatts. Governor Greg Abbott is a strong supporter of cryptocurrencies and hopes to turn Texas into a global mining hub. Texas has became the second state, after Wyoming, to recognize digital money as a legitimate financial instrument.
In addition, the bitcoin business has made South Florida a hotbed of activity. Miami Mayor Francis Suarez is enthusiastic about digital currency and is working to make the city a viable destination for miners, cryptocurrency exchanges, and crypto investment organizations. Suarez, on the other hand, is a proponent of long-term coin mining; he recently pushed mining businesses to purchase property near Miami nuclear power stations in order to manufacture bitcoin using nuclear power.
Kazakhstan and Russia, on the other hand, cannot boast of significant renewable energy investments. In Kazakhstan, 85 percent of power is generated using fossil fuels, whereas in Russia, 88 percent is generated using fossil fuels. Experts think, however, that Kazakhstan, which borders China, is simply a stopover for miners on their way to the West. In addition, extra taxes will be imposed on cryptocurrency miners in the nation in a few months, commencing in January 2022. Then Kazakhstan will lose both of the features that drew miners in the first place: the promise of low-cost currency creation and the lack of official supervision.
According to Igor Pavlov, the leader of the Waves Node development group, Russia's domestic mining pool is concentrated in Siberia, where output and population density are low. As a result, the use of power for the extraction of digital money has no more environmental impact than other businesses. The Russian Association of Cryptoindustry and Blockchain (RACIB) is another organization in the nation that actively promotes the growth of sustainable energy.
Russia's hydroelectric resources account for 20% of the country's total.
"The hydroelectricity potential of southern Siberia and the Far East can attract miners not only from Russia but also from neighboring countries," according to the RACIB. According to the International Hydropower Association, Russia has the world's second-largest unexplored hydropower resources, with just 20% of them being exploited now.
Many miners are attempting to make amends for the planet's harm. For every million Canadian dollars ($ 788.2 thousand) invested in their Bitcoin ETF, for example, the Canadian financial firm Accelerate has vowed to plant 3,450 trees (an investment fund, each share of which is tied to a certain part of its assets). Each investment, according to the corporation, will cut global carbon dioxide emissions by a thousand tons.
Aside from that, mining may be used to help reduce carbon emissions. Great American Mining, a bitcoin startup based in the United States, employs an unusual form of energy to power its computers: associated petroleum gas. This material is released during the extraction and processing of fuel in the fields, and oil producers simply burn it if there is no other purpose for it. Associated petroleum gas has long prohibited enterprises from meeting their climate targets, which is why Great American Mining has recommended that instead of wasting this energy by polluting the environment, it be used to create digital money.
"Great American Mining is monetizing the oil and gas industry's worthless, inefficient, and devalued gas by using it as a source of energy for mining bitcoins," according to the company's website. The startup has already formed a partnership with Fortress Technologies, a big crypto corporation. Furthermore, oil companies such as Equinor in Norway, Enerplus in Canada, and Kraken Oil & Gas in the United States began to adopt the technique. Only the United States and Canada produce enough associated petroleum gas to serve the whole Bitcoin network, thus the endeavor has a lot of potential.
Mining farms throughout the world are "spitting forth random numbers around the clock in a competition to solve a pointless riddle," as Senator Elizabeth Warren phrased it. Even if cryptocurrency opponents feel that the energy used to run computers is "wasted," the industry has a counter-argument: miners have learnt to reuse power. Mint Green, a Canadian business, has patented "digital boilers" that recover more than 96% of the power required to generate Bitcoin.
This energy is converted into heat via technology, which may then be utilized to heat residential areas and run industrial activities. In North Vancouver, Canada, the firm has already secured a deal with an energy supplier to begin heating over 100 residential and commercial buildings with revolutionary low-carbon energy in 2022. MintGreen technology will assist prevent the emission of 20 thousand tons of greenhouse gases into the environment that would otherwise be created by natural gas.
Single miners have known for a long time how to get two benefits from their computers: mining earnings and free electricity. Miners create electric boilers with ASICs (application-specific integrated circuits) as the heating element. Miners use immersion liquid to cool automobiles and extract heat, which is then used to heat homes, water, and underfloor heating, among other things.
At a 1:1 ratio, all power consumed in mining may be turned to heat. Six Bitmain Antminer S17 ASICs functioning at maximum capacity consume around 18 kilowatt hours, according to BiXBiT's website. It is feasible to heat a living space of 150-180 square meters by transforming this energy into heat.
The caravan goes
The true size of the crypto market's harmful impact on the environment, according to analysts at the popular scientific publication Harvard Business Review, is significantly less serious than widely assumed. Vitaly Borshchenko, the creator of BitCluster, agrees, saying that the situation is "definitely not serious" on a worldwide scale and in relation to other businesses. Furthermore, with the large exodus of miners from China's "coal power," the environmental damage caused by the sector might be greatly decreased. It's also vital to note that the type of energy utilized, not the amount, determines the amount of hazardous pollutants. When compared to coal-fired electricity, one unit of hydropower has a far smaller environmental effect.
Traditional banking, in fact, is proving to be considerably more harmful to the environment than the nascent Bitcoin business. Bitcoin mining, according to mining specialist Hass McCook, amounts for less than 5% of the global financial sector's carbon emissions. According to ARK Invest experts, traditional banking systems emit 1.37 million megatons of carbon per year, gold mining 144 megatons, and the bitcoin network 61 megatons. Bitcoin emissions are under 5% of the total amount of pollution produced by the financial industry, and the damage caused by its network on a worldwide scale is negligible.
In terms of public disapproval, many politicians' views on the issue of cryptocurrencies are populist, according to Evgeny Shatov, partner at Capital Lab. Mining criticism, he believes, is an attempt to get votes by speaking out on a contentious issue. Elon Musk, the billionaire, also speculates on the appeal of digital currency. Some analysts believe that his restriction on selling Tesla for bitcoins is more of a game of the cryptocurrency market than a genuine fight for the planet's future, because his announcement caused the currency rate to plummet by 17%.
Tesla purchased bitcoins for $ 1.5 billion in December 2020, profitably sold the coins, and earned roughly $ 100 million. Furthermore, three days before the sale of electric automobiles for bitcoins was suspended, the space firm Mask SpaceX said that it would take Dogecoin as payment for launching a satellite to the moon.
Get out of your comfort zone
Miners, in actuality, are quite conscious of their carbon footprint. Cryptocurrency miners have even signed their own climate deal, akin to the UN Paris Agreement, called the Crypto Climate Accord. All signatories to the agreement are cryptocurrency market players who publicly pledge to emit zero harmful emissions from the use of power to manufacture coins and operate the network by 2030. Over 200 firms and individuals from all over the world have already signed the pact.
Mining, like any other volatile business, has a negative impact on the environment. However, the business has only been around for a little over a decade, and its advantages to the financial world are not well known; it has yet to prove its right to exist. Because many detractors wonder if digital money is worthy using such a big quantity of expensive power, the crypto community must not only acknowledge, but also properly tackle its "climate concerns."
"If kriptorynka officials work in good faith to reduce their carbon footprint, they will be able to demonstrate that the social benefit of digital money is worth the resources necessary to maintain it," the Harvard Business Review journalists write. Many digital money companies have already displayed a mindful commitment to climate change, but the sector need radical new ideas to survive in the face of imminent tragedy.
