Are bitcoins worth the electricity used for production
People will collect anything. Baseball cards, stamps, Pez dispensers — somewhere, somebody probably has 10, of them. Some collectibles, like rare books or works of art, are valuable in large part because of their intrinsic worth or beauty. But whether the object is a Picasso or a Babe Ruth rookie card, it is generally true that the rarer the item, the more expensive it is likely to be.

What is Bitcoin mining and how does it work?
Downpours transform the mottled landscape into lush emerald, while azaleas bloom and migrating cranes and storks begin the long journey back north. The rainfall also brings trucks stacked with computers to hydropower dams, where entrepreneurs can tap cheap electricity for mining bitcoin—the arcane process that accumulates the cryptocurrency using huge amounts of computing power to solve equations. Cryptocurrency mining requires huge amounts of computing power, making energy consumption a major overhead for the industry.
Local governments will often offer power for pennies—or even free—to attract jobs and get a painless boost to their gross domestic product figures. While individual miners and traders may be able to slip through the cracks, larger commercial miners will likely be considering alternative mining hubs with less rigorous regulatory regimes, analysts say.
Last week, a number of companies involved in cryptocurrency mining began halting operations in China. Jiang Zhuoer, chief executive of BTC. Before the crackdown, bitcoin mining in China was projected to generate more than million metric tons of carbon emissions by , according to a study published in scientific journal Nature Communications. If the global bitcoin mining industry were a country, it would be the 29th biggest consumer of power in the world on a list of nations by energy use, above Argentina, which has a population of roughly 45 million.
Mining rigs are driven thousands of miles across China to the belching power stations of Inner Mongolia or Xinjiang province. While most crypto mining operations in China could be considered legal grey areas, some are outright illegal, says Tang.
Bitcoin miners are essentially paid to work as auditors, verifying the legitimacy of transactions, while allowing a trickle of new units of the currency into the economy. And when miners earned cryptocurrencies, they had to exchange them covertly as private individuals, usually overseas. This incongruity has become stark: scores of tech companies with plush offices in Shenzhen and Shanghai purport to be engaged in artificial intelligence, big data processing, or blockchain for commercial use, but in reality they earn their money from crypto mining at faraway dams and power plants.
Crackdowns have happened before. Back on Sept. A high concentration of mining activity in one country threatens the entire system that underpins cryptocurrencies. Vulnerabilities arise when so much mining capacity is concentrated in one place. One of the core security pillars of the blockchain technology upon which cryptocurrencies operate is that transactions are transparent and publicly verifiable.
But what if a large proportion of bitcoin miners—perhaps ordered by a government—together decided to manipulate a ledger in a particular way? This could potentially trigger a fork in bitcoin, or at least sow sufficient uncertainty to roil the market.
That is a concern. In regions where power supplies are unstable, the amount of energy required for mining can also be problematic. In Iran, blackouts and power shortages prompted the government to ban crypto mining on May Before the recent crackdown, efforts were being made to clean up the bitcoin mining industry. As well as consuming an enormous amount of power, mining rigs generate a whopping amount of heat and need to be cooled by fans which, in turn, use more energy.
Technological advancements, such as liquid cooling for computers, can help reduce power consumption. In more ambitious plans, some towns in Xinjiang province have been experimenting with using the high temperatures produced by mining rigs to provide heat to the community. But the impact of crypto mining goes beyond climate. The surging price of bitcoin before the crackdown encouraged the tech-savvy across China to turn computers otherwise used for artificial intelligence or big data crunching to mining operations.
The resulting rise in demand for fossil fuels prompted some coal miners to restart mothballed mines without official approval, leading to a spike in deadly accidents, according to Al Jazeera. In an effort to reduce power consumption, Inner Mongolia last week issued draft guidelines to curb crypto mining by withdrawing preferential policies for big data centers and cloud computing firms, while announcing that telecommunication companies, internet firms and even internet cafes would have their business licenses revoked if they engaged with crypto mining.
The local government has even set up a new hotline so citizens can report suspected mining operations. Analysts say that the regulatory crackdown will likely prompt big commercial mining operations to flee China en masse for alternative hosts, such as Mongolia, Kazakhstan and Afghanistan.

Explained: Why Bitcoin’s electricity consumption is very high, and its implications
How bad is bitcoin mining for the environment really?
The bitcoin network is burning more and more energy for mining bitcoins. The total power consumed by the bitcoin network has already crossed the consumption level. Last year, the electricity consumed by the network for mining bitcoins was estimated to be around 67 terawatt-hours TWh. The consumption this year has already surpassed that mark and by the end of , the mining looks set to have consumed 91TWh of energy — as much as Pakistan, according to a research report by Bloomberg. It noted that as the bitcoin price goes up, more bitcoin miners join the network with less energy-efficient machines to mine bitcoin that pushes the use of energy. The high use of electricity for mining bitcoin has also made it increasingly important to switch to low-carbon energy sources for electricity.

Bitcoin’s energy consumption? Greater than Chile, Austria and the Czech Republic
In little over a decade, bitcoin has risen from a fringe technology popular with cryptographers, to the world's ninth most valuable asset by market cap. The cryptocurrency 's dramatic ascent has created millionaires, reimagined money, and launched a multi-billion dollar industry inspired by its revolutionary decentralised technology. But it has also brought with it some unwanted side effects. The computing power required to support bitcoin's underlying network now requires nearly as much energy as the entire country of Argentina, leading to criticism about its environmental footprint. Analysis by the University of Cambridge suggests the bitcoin network uses more than terawatt-hours TWh annually, which would rank it in the top 30 electricity consumers worldwide if it were a country.
Bitcoin energy use - mined the gap
Bitcoin representational image. For Bitcoin enthusiasts, first, the good news. Which means, it is now easier and more profitable to mine Bitcoins. However, if one scratched beneath the surface, it would become evident that the easing off in mining difficulty is a move that is linked ultimately to the high environmental cost that the activity was seen as extracting. Authorities in China, which accounted for as much as 65 per cent of the global production of Bitcoins last year, have cracked down on mining after it became evident that miners were using up massive amounts of energy.
Electricity needed to mine bitcoin is more than used by 'entire countries'
Four years ago, the Scrubgrass power plant in Venango County, Pennsylvania, was on the brink of financial ruin as energy customers preferred to buy cheap natural gas or renewables. Then Scrubgrass pivoted to Bitcoin. Today, through a holding company based in Kennerdell, Pennsylvania, called Stronghold Digital Mining that bought the plant, Scrubgrass burns enough coal waste to power about 1, cryptocurrency mining computers. These computers, known as miners, are packed into shipping containers next to the power plant, the company stated in documents filed with the U. Securities and Exchange Commission ahead of its initial public offering.
The debate about cryptocurrency and energy consumption
The financial community sees speculative promise in the form of trade that currently has little to no regulation. I am a researcher who studies clean energy technology, specifically the transition toward decarbonized energy systems. I think that the conversation around bitcoin and energy has been oversimplified.
Bitcoin will consume a ‘Pakistan’ worth of electricity in 2021RELATED VIDEO: Bitcoin's Energy Consumption Problem
Why does Bitcoin consume electricity? Does energy usage increase with the number of transactions? Are Bitcoin miners polluters? Will Bitcoin miners pollute more or less in the future?
The rising energy usage of blockchains has recently been facing increasing public scrutiny. Most recently, Tesla CEO Elon Musk announced that the company would suspend vehicle purchases using Bitcoin and only resume once mining shifts to more sustainable energy sources while Tesla studies other, more efficient, cryptocurrencies. Interestingly, the recipient of the first-ever Bitcoin transaction, computer scientist Hal Fi n ney , first raised the issue of how to reduce CO 2 emissions from potential widespread Bitcoin adoption back in January , only three months after the Bitcoin whitepaper was first published. Public, permissionless blockchains, such as Bitcoin and Ethereum, the largest and second-largest blockchains by market cap, rely on proof of work 1 PoW to process transactions and provide network security.

The skyrocketing value of Bitcoin is leading to soaring energy consumption. According to one widely cited website that tracks the subject, the Bitcoin network is consuming power at an annual rate of 32TWh—about as much as Denmark. By the site's calculations, each Bitcoin transaction consumes kWh, enough to power homes for nine days.
