The growing energy consumption and associated carbon emission of Bitcoin mining could potentially undermine global sustainable efforts. By investigating carbon emission flows of Bitcoin blockchain operation in China with a simulation-based Bitcoin blockchain carbon emission model, we find that without any policy interventions, the annual energy consumption of the Bitcoin blockchain in China is expected to peak in at

Cryptocurrency Mining Impacts the World’s Poorest the Most

On the shores of Seneca Lake in upstate New York, a private equity company has bought a decommissioned coal power plant and converted it to burn natural gas.
The company says it is proud of shifting away from coal. It is looking to buy more power plants and vastly scale up operations. Climate activists, however, are aghast that fossil fuels will be burnt to mine crypto, and are pushing regulators to clamp down on this and other similar projects to prevent a surge in greenhouse gas emissions. Musk said last week he had changed his mind , and reversed plans outlined in February to accept bitcoin for payments for his vehicles.
The statement generated a backlash from bitcoin believers , some of whom have made huge returns from early bets on the asset class and see it as the future of money. Crypto proponents have accused him of ignorance over mining methods or of seeking to protect the shadowy interests of big government. It is a question so far largely ignored by governments, by heavy-hitting environmental charities, and by the banks and exchanges that facilitate the vast cryptocurrency industry.
Economic authorities are starting to take notice. Measuring precisely how dirty bitcoin is has become a cottage industry in itself. That places it just above Sweden, at The rationale: a rising bitcoin price attracts new miners, and also means that mining with older, less efficient equipment, makes financial sense.
The higher price also means the machines producing bitcoin are forced to complete ever-tougher puzzles in search of their quarry. The UK consumes TWh. About 65 per cent of the crypto mining comes from China, where coal makes up around 60 per cent of the energy mix.
Naturally, there is space for disagreement on these statistics, and all studies on the issue accept elements of uncertainty. Rauchs points out that a slice of the mining in China comes from clean hydroelectric power, including with machines that are transported from the north to the south of the country on trucks each year in the wet season.
That hydro power is not necessarily diverted from anywhere else; some of these power stations were founded for factories that no longer exist, Rauchs says. About 75 per cent of miners use some kind of renewable energy, Cambridge studies show, but renewables still account for less than 40 per cent of the total energy used. Some mining may also be conducted off-grid, making it harder to track. All this nuance makes a difference. Energy consumption on some scale is a feature, not a bug, of bitcoin — a digital currency launched by the pseudonymous Satoshi Nakamoto 12 years ago.
Its detachment from the global financial and governmental system — still the most alluring feature for users seeking anonymity or wishing to bypass central banks — means it needs a new way to establish trust and security. The puzzles are sufficiently hard to prevent hackers and other nefarious actors from taking control of the network, and the faster that miners can submit random numbers into the bitcoin algorithm, the more likely they are to unlock the coins.
This all demands powerful machines running at full tilt. Luckily for bitcoin miners with access to cheap energy and efficient machines, it is usually worth it. Bitcoin is not the only energy-intensive cryptocurrency, but it is by far the biggest. Others include litecoin, ether and the light-hearted but rapidly growing dogecoin — initially an internet joke based on a Shiba Inu dog.
Ether, the cryptocurrency native to the ethereum blockchain network, has been working on a shift to this model for more than two years, but the project is dogged by technical difficulties.
Musk has also dangled the possibility that he could back other coins with a lighter energy impact. A greener version of bitcoin is, in theory, possible. However, every miner would need to switch for the new path to work.
Industry insiders say it is hard to imagine the entire bitcoin community, which is peppered with disagreements, lending support to such a plan. Other ideas, such as labelling individual bitcoins as clean or dirty depending on the energy used to mine them, would also be hard to verify, and create a two-tier bitcoin system that was likely to lack support.
It consumes more electricity than a country. All the rest is detail. Yarovaya, a former Russian Paralympic swimmer, frequently fields criticisms of her analysis and motivations from bitcoin proponents. She is undeterred, however. It is a speculative asset. It does not create a substantial amount of employment.
Such concerns have not, however, sparked high-profile campaigning from environmental groups. Friends of the Earth, an advocacy group, says it is still getting to grips with the issue, as is Greenpeace, whose US arm started accepting bitcoin donations in After inquiries from the Financial Times, Greenpeace says it will now scrap the facility, which has not been heavily used. Environmental concerns have also not deterred a clutch of investment banks from entering the sector, despite their public commitments to sustainable development goals: Citigroup said recently it was exploring what role it could play in crypto services; Goldman Sachs has reopened bitcoin derivatives trading ; and Morgan Stanley plans to offer clients access to bitcoin funds.
None of these banks wished to comment on the issue of energy consumption. Nigel Topping, who was appointed by the UK government to co-ordinate with businesses over climate goals ahead of the COP26 talks later this year, says bitcoin is not likely to be on the agenda for climate discussions among governments in Glasgow, but it is starting to become a real issue in broader policy discussions.
Proof of work is proof of burning [fossil fuels]. The group is not aiming to slow innovation in digital finance, but wants to ensure that future blockchain-based projects are designed to consume less energy. Do crypto market participants worry about the energy usage? Bitcoin proponents remain convinced that the benefits outweigh the costs, arguing that cryptocurrencies provide the basis for the financial system of the future.
Banks and asset managers keen to meet client demand for crypto services are looking at carbon offsets. Much heavier reliance on renewable energy would soften the blow, but would still draw criticism by diverting clean power from other parts of society. After protests by residents and green NGOs, the Greenidge project in New York state announced plans to make its bitcoin generation carbon neutral by buying carbon credits.

What is Bitcoin?
Author: Donal Lally. How the combination of domesticated fire, the data center, and artificial intelligence is reshaping our communities, opening them up to a stealthier and more pervasive form of the Smart City. For Semper, the first human groups assembled, formed alliances, and developed religious concepts around the domesticated fire. Fire is both metaorganic and metacultural.
Faster and greener: Reducing the carbon footprint of Bitcoin mining
Bitcoin and other prominent cryptocurrencies have gained much attention since the last several years. Globally known as digital coin and virtual currency, this cryptocurrency is gained and traded within the blockchain system. The blockchain technology adopted in using the cryptocurrency has raised the eyebrows within the banking sector, government, stakeholders and individual investors. The rise of the cryptocurrency within this decade since the inception of Bitcoin in has taken the market by storm. Cryptocurrency is anticipated as the future currency that might replace the current paper currency worldwide. Even though the interest has caught the attention of users, many are not aware of its opportunities, drawbacks and challenges for the future. Researches on cryptocurrencies are still lacking and still at its infancy stage.
Gold and bitcoin: Tax implications of physical and virtual mining
One of the disadvantages of Bitcoin that its proponents often gloss over is the fact that its mining algorithm has little real-world value. It has always been thought that we could do better. Many newbies to Bitcoin immediately suggest that the mining algorithm should have involved SETI home or folding home , so that the computations would also help bring humanity closer to curing protein misfolding diseases or finding aliens. The problem is, however, that Bitcoin mining requires one key property that SHA does have but SETI home and folding home do not: it is efficiently verifiable. Primecoin is the first proof-of-work based cryptocurrency that has come up with any kind of workable solution.
The Rise and Fall of Bitcoin
The price of Dogecoin has appreciated dramatically since May see Figure 1 , but it remains a relatively cheap coin with a very large supply. But what exactly is it — and does it have any value? Dogecoin is a cryptocurrency that began as a joke , taking its name and logo from a meme of a Shiba Inu dog that became popular online in It was founded by Jackson Palmer — a software engineer working for Adobe — although he has since walked away from the project. Palmer had two tabs open side-by-side on his computer — one was CoinMarketCap an aggregator of data on cryptocurrencies and the other was a news article about the best meme of , Doge. When switching between the tabs, Palmer had the idea to put the two elements together and quickly tweeted about a hot new cryptocurrency called Dogecoin and bought the website domain.
A Study on the Optimization of Blockchain Hashing Algorithm Based on PRCA
By Jacob Aron. The virtual currency is about more than money — the real innovation is what people are doing with the technology it is based on. That fundamental concept is being used to transform Bitcoin — and could even replace it altogether. So what is the block chain? It is a ledger of transactions that keeps Bitcoin secure and allows all users to agree on exactly who owns how many bitcoins. Each new block requires a record of recent transactions along with a string of letters and numbers, known as a hash, which is based on the previous block and produced using a cryptographic algorithm.
Dogecoin: what is it and does it have any value?
Virtual currency Bitcoin has attracted increasing media attention over the past year. So has the media hype driven the price hike? To the average man in the street, Bitcoin is a complicated concept.
Welch holds the J. Fred Weston Chair in Finance. Digital currencies, in their current form, should be prohibited by law. And not because they are a Ponzi scheme which they are , and not because they can help facilitate criminal activity which they do , but because they incur colossal social waste. This waste is energy.
