Crypto mining ecology
Jeff Thomson , Seattle University Follow. The use of cryptocurrencies in daily life has continued to rise over the last decade and shows no signs of slowing down. Although cryptocurrencies, such as Bitcoin, provide numerous tangible benefits to society, the process of mining these cryptocurrencies is extremely energy intensive. Accordingly, a tragedy of the energy commons has resulted whereby the monetary incentive to mine cryptocurrencies has distorted our collective ability to care for our shared energy resources. The current system allows for industrious individuals to set up cryptocurrency mines in regions that have access to plentiful and cheap energy sources, utilize this energy to power their mining activities, and leave the region when the energy becomes more expensive than other regions.

Be skeptical. The cryptocurrency bitcoin has become notorious for its ravenous appetite for electricity — and its presumed massive carbon footprint. A June paper in the journal Joule estimated that annual carbon dioxide emissions from the bitcoin network are as high as It also accounts for 0. But another recent study by CoinShares , a cryptocurrency asset management and analysis firm, found that the majority of the electricity used by bitcoin actually comes from clean sources, like wind, solar, and hydropower.
CoinShares says bitcoin network gets Analysts also warn that the same factors that pushed miners to use clean energy could one day lead them to back to dirty fuels. The CoinShares study also points to a broader problem for how renewable energy is currently deployed around the world: Many renewable power generators are so poorly located and underused that mining bitcoin has become the only viable use for that electricity. Even though bitcoin solely exists in digital zeroes and ones, the computers that run the network are huge energy hogs.
According to the bitcoin energy consumption tracker at Digiconomist , bitcoin currently consumes Since there is no central bank or authority governing the currency, the bitcoin network regulates itself through a distributed accounting system known as blockchain. In blockchain, every bitcoin transaction is tracked in a public ledger spread across thousands of computers.
These transactions are grouped into blocks. The bitcoin network creates an incentive for people to contribute computing power to verify transactions by awarding bitcoins to a miner who verifies a block currently Blocks are added to the blockchain roughly every 10 minutes. But mining is competitive, with only one miner winning the award per block.
Over time, the calculations needed to verify a block get more difficult and the bitcoin award shrinks. The price is also unstable. These factors have created an arms race to develop better computer hardware to more rapidly verify transactions and a push to devote ever-increasing amounts of electricity to the task. Between 60 and 80 percent of bitcoin mining revenue goes straight back into paying for electricity.
So miners really, really want to save as much on their electricity bills as possible. The quest for the cheapest kilowatt has led miners to set up shop in remote regions of China and Mongolia.
Bitcoin mines have gone up in rural Washington state. The hunt for cheap power has even led to cases of electricity theft. Since the network is spread all over the world, bitcoin miners often want to remain anonymous and keep their operations opaque. Another factor is that the computing hardware miners use, known as an application-specific integrated circuit ASIC , has been getting more energy efficient over time.
But mining operations are continually deploying more of them. The power grids miners draw on are also changing over time and can change in their fuel sources between seasons. That means a local utility could be getting cleaner or dirtier over time, and if more fossil fuels are coming online to meet the demand, that would lead to more greenhouse gas emissions. In so doing, the CoinShares team found that bitcoin miners were using a disproportionate share of renewables.
This is why you see miners flock to regions where high-powered renewables are abundant. Regions with high levels of renewable energy and low demand are often areas that saw local industries leave in recent years and subsequently experienced a population exodus. So bitcoin miners, who care more about electricity costs than location, happily moved into renewable-powered rust belts around the world.
Governments have had mixed reactions to the rise of cryptocurrencies like bitcoin and their rapacious demand for electricity. In Quebec , the government is offering discounted electricity to lure in miners to boost the economy.
Meanwhile, China is weighing an outright ban on cryptocurrency mining because it sees miners as scofflaws that are wasting resources and damaging the environment. Bendiksen said bitcoin mining is making use of energy resources that would otherwise go to waste and that renewable power mitigates its environmental footprint. He noted that its estimate of renewable energy use in bitcoin mining is out of line with other calculations.
A report from the University of Cambridge , for example, found that while the majority of bitcoin mining facilities drew on renewables to some extent, the average share was just 28 percent. In a separate paper published in Joule in April, de Vries explained that even the renewables being used for bitcoin mining have their own consequences.
Hydropower in particular has huge regional environmental effects and sometimes has to be backed up by fossil fuels. Production of hydropower is high in the wet season during the summer months and low in the dry season during the winter months. And since miners are concerned about energy costs above all else, a glut in coal, oil, or natural gas could make burning them much more attractive.
Another emerging concern around bitcoin is the electronic waste. But mining bitcoins remains profitable, so the amount of hardware it uses and the quantity of electricity it inhales will continue to surge dramatically for years. Another price spike could push energy use even higher.

Electricity needed to mine bitcoin is more than used by 'entire countries'
When bitcoin BTC , the first pioneering cryptocurrency was released in , it was considered an apolitical currency. Besides, the possible effect of BTC and other cryptocurrencies on either financial markets or transactions has been widely discussed. However, the environmental effects of cryptocurrency demand have been ignored. Here, this study examines the nexus between cryptocurrencies and environmental degradation by employing standard and asymmetric causality methods. The Fourier-augmented Toda-Yamamoto test results show causal effects running from Bitcoin and Ripple to environmental degradation, whereas no causal effect runs from Ethereum to environmental degradation. The asymmetric causality shows causal effects from the positive shock of Bitcoin demand, negative shocks of Ripple and Ethereum demands to positive shocks of environmental degradation. Further discussions and policy implications are provided in the relevant sections of this study.
Tesla suspends Bitcoin use. Here's how mining cryptocurrency affects the climate
But concern over the energy-intensive process of bitcoin mining, which requires high-powered computers sometimes deployed on an industrial scale, has drawn scrutiny to the environmental impact of the world's largest cryptocurrency. In a new interview, Tom Steyer — a hedge fund billionaire and environmental advocate — described bitcoin as a "huge user of electricity," contending the cryptocurrency will remain an environmental threat as long as the energy grid depends on fossil fuels. Steyer sharply criticized bitcoin mining ventures that seek out cheap, dirty energy in order to maximize profits. This is a great money making opportunity. That is a disaster. That is a straight up disaster," he says. Bitcoin mining, the process that records transactions and brings new bitcoins into circulation, demands miners solve complex math problems using advanced computation. In exchange, they receive a portion of bitcoin as a reward, making the task potentially lucrative, especially as the price of bitcoin continues to climb. An analysis conducted by Cambridge University, released in February, found bitcoin mining consumes
Why Bitcoin Is Bad for the Environment
Want to discuss? Please read our Commenting Policy first. On Wednesday, Elon Musk, the chief executive of Tesla, said his company will no longer accept Bitcoin for car purchases, citing environment al concerns, in a swift reversal of its position on the currency after criticism by some investors. However, there are growing attempts to turn bitcoin green and mitigate the environmental harm of mining — and this is happening in Canada.
Study says bitcoin could derail China's climate change targets
Musk cited concerns with the fossil fuel emissions of the mining process as the reason behind the decision. On the surface, it may seem unlikely that digital currencies would have significant carbon footprints. But cryptocurrency mining, the process that adds new units of crypto into circulation, is highly carbon intensive —— the entire Bitcoin network consumes more energy than many countries do annually. And we can't really afford to have systems decreasing our energy efficiency now. The high energy consumption of cryptocurrencies like Bitcoin and Etherium is mainly attributed to the proof-of-work protocol that governs their mining and transaction processes.
How serious is the threat of Bitcoin mining to the environment?
Tesla CEO Elon Musk, in what can only be called a sudden "U-turn", announced late on Wednesday that he was reversing course on the decision to use Bitcoin as an acceptable form of payment for the purchase of vehicles. Citing climate change concerns, Musk declared that the electric vehicle manufacturer is suspending purchases with the cryptocurrency, sending its rates down a free fall.

Elon Musk, the chief executive officer of Tesla, took to his official Twitter handle to post a statement: "We are concerned about rapidly increasing use of fossil fuels for Bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel. Mining Bitcoin and other cryptocurrencies could leave adverse impacts on the environment, some fear. Here's the gist of the argument:. Bitcoin is a cryptocurrency, a decentralised digital currency created as a reward for a process known as 'mining' -- which involves using computers to solve complex mathematical algorithms.
A Comparison Of Bitcoin’s Environmental Impact With That Of Gold And Banking
Summer on Seneca Lake, the largest of the Finger Lakes in upstate New York, is usually a time of boating, fishing, swimming and wine tasting. But for many residents of this bucolic region, there's a new activity this season — protesting a gas-fired power plant that they say is polluting the air and heating the lake. They have increased the electrical power output at the gas-fired plant in the past year and a half and use much of the fossil-fuel energy not to keep the lights on in surrounding towns but for the energy-intensive "mining" of bitcoins.
By Anna Irrera , Tom Wilson. The digital currency is created when high-powered computers compete against other machines to solve complex mathematical puzzles, an energy-intensive process that currently often relies on fossil fuels, particularly coal, the dirtiest of them all. Bitcoin production is estimated to generate between 22 and Tesla did not respond to a request for comment. They add that companies could buy carbon credits to compensate too. Other companies are likely to follow its lead by buying into the currency, investors and industry experts say.
I give you a slip of paper or, more likely these days, a piece of plastic. You hand me eggs or butter or a White Chocolate Mocha Frappuccino, and we both walk away satisfied. With cryptocurrency, the arrangement is more like a shared metafiction, and the instability of the genre is, presumably, part of the thrill. Dogecoin, a cryptocurrency that was created as a spoof, has risen in value by eight thousand per cent since January, owing to a combination of GameStop-style pumping and boosterish tweets from Elon Musk. On Tuesday, which backers proclaimed DogeDay, the cryptocurrency was valued at more than fifty billion dollars, which is more than the market cap of Ford. Coinbase, a cryptocurrency exchange, went public last Wednesday; almost immediately, it became worth more than G. Sign up to receive news and commentary in our Climate Crisis newsletter.
I n Scotland this month, world leaders bickered about global efforts to reduce carbon emissions at the COP26 summit. Meanwhile in the oil-drilling capital of Alberta, Canada, a tech company is doing its own small part to help the world reach carbon neutrality: turning oil waste into environmentally-friendly energy that powers crypto mining. This self-sustainable system, developed by a company called CurrencyWorks , will ultimately help power the distribution of Zero Contact , a new movie starring Anthony Hopkins, which is set for release next month as an NFT, or non-fungible token , with zero carbon footprint. At the Canadian plant, municipalities pay a fee to give away their waste.
