The map below shows which countries in Europe consume more or less electricity than Bitcoin mining: Which European countries consume more or less electricity than the amount consumed by global bitcoin mining. Also see: Also see: Find this post interesting? Bitcoin is the first, and the biggest, cryptocurrency a decentralised tradeable digital asset. This dilemma has raised environmental concerns over Bitcoins, in addition to those stemming from their legal status). If you find an article missing from this list please report it here, and it will be added as soon as possible. Bitcoins electricity usage is enormous. This means that visa has an energy need equal to that of around 17,000.S. That is the surge in global electricity consumption used to mine more Bitcoins. Bitcoin and most other cryptocurrencies are founded on the notion of an immutable ledger, called the blockchain, which comprises transfers of value from one party to another. Ever since its inception Bitcoins trust-minimizing consensus has been enabled by its proof-of-work algorithm.
The most detailed available report on cryptocurrency mining facilties is this study by Garrick Hileman and Michel Rauchs from 2017. The Bitcoin price at the time had just dropped 60 compared to the peak just several months before. A separate index was created for Ethereum, which can be bitcoin global power consumption found here. One can argue that specific locations in these countries offer less carbon intense power, but unfortunately, this is the most granular level of information available. In simplified terms, bitcoin mining is a competition to waste the most electricity possible by doing pointless arithmetic quintillions of times a second. And while marijuana farmers and data centre engineers managed to reduce their power demands, the fundamentally wasteful nature of bitcoin mining means theres no easy technological solution coming. Energy consumption of visa offices isnt included but the differences are so extreme that they will remain shocking regardless. The model predicts that miners will ultimately spend 60 of their revenues on electricity. Bitcoin's electricity consumption as a percentage of the world's electricity consumption.27, annual carbon footprint (kt of CO2) 28,716, carbon footprint per transaction (kg of CO2) 214.09 *The assumptions underlying this energy consumption estimate can be found here. In their second study, Hileman and Rauchs identified cryptocurrency mining facilities with a total capacity.7 gigawatts. The map below shows how much more or less bitcoin mining energy consumption compares to each countries energy usage with 100 being equal. 12.5 bitcoin still worth over 100,000 plus all the transaction fees paid in the past 10 minutes, which according analysts estimates is another 2,500. To put it simply, the higher mining revenues, the more energy-hungry machines can be supported.
They also bitcoin global power consumption have to contribute computing assets, but the overall computational power required is far lower than the bitcoin approach and grows slowly over time. And at a bitcoin price.1m, it would be profitable to use almost all the electricity currently generated in the world for mining. Bitcoin Mining consumes more electricity than 12 US states (Alaska, Hawaii, Idaho, Maine, Montana, New Hampshire, New Mexico, North Dakota, Rhode Island, South Dakota, Vermont and Wyoming). Every miner individually confirms whether transactions adhere to these rules, eliminating the need to trust other miners. Even so, economics showed room for further growth of the networks energy consumption continued to exist despite these facts. If Bitcoin was a country, it would rank as shown below. This means the estimated annualised global mining revenues now stand.2 billion USD (5.4 billion), which even at the more expensive estimates listed above, means its still very profitable. The trick is to get all miners to agree on the same history of transactions. The index is built on the premise that miner income and costs are related. These articles have served as an inspiration for the Energy Index, and may also serve as a validation of the estimated numbers. One might assume that the use of hydropower implies that the Bitcoin network has a relatively low carbon footprint. The Bitcoin Energy Consumption Index therefore proposes to turn the problem around, and approach energy consumption from an economic perspective. Thats the equivalent.13 of total global electricity consumption.
This obviously does not account for less efficient machines in the network and, more importantly, the number is not corrected for the Power Usage Effectiveness (PUE) of Bitcoin mining facilities. As such, the report does not provide any more than speculative assumptions in addition to the work already done by Hileman and Rauchs. Whether it is a bad investment is the big question. The Bitcoin Energy Consumption Index estimates consumption has increased.98 over the past month. To ensure that coins cannot be bitcoin global power consumption minted too quickly, as the overall networks computational power increases, the bitcoin protocol continually makes it harder to find a putative solution. Interestingly, Bitcoins price increase over the last month has been just over 40, which is greater than the increase in electricity consumption. (21,776 TWh) The Cost of Mining Bitcoins The Bitcoin Energy Consumption Index estimates that the total annual cost of mining Bitcoins stands.5 billion (1.1 billion). We also know visa processed 111.2 billion transactions in 2017. Amid increasing demand for Bitcoin due the skyrocketing prices in the last months, the global energy consumption used in the production process of the virtual currency known as "mining" surpasses the individual consumption of 159 individual countries. NEW: Bitcoin Electronic Waste Monitor, download data.
But in the western United States, some utility companies have responded by freezing service to new cryptocurrency installations or charging them higher rates; and Chinese authorities have started destroying smaller hydroelectric projects (some illegal and are connecting others. The table below features a breakdown of the energy consumption of the mining facilities surveyed by Hileman and Rauchs. Apart from the previous comparison, it also possible to compare Bitcoins energy consumption to some of the worlds biggest energy consuming nations. In 2018 Bitcoin company Coinshares did suggest that the majority of Chinese mining facilities were located in Sichuan, using cheap hydropower for mining Bitcoin. This arbitrary approach has therefore led to a wide set of energy consumption estimates that strongly deviate from one another, sometimes with a disregard to the economic consequences of the chosen parameters. The main challenge here is that the production of hydropower (or renewable energy in general) is far from constant. Carbon footprint Bitcoins biggest problem is perhaps not even its massive energy consumption, but the fact most mining facilties in Bitcoins network are located in regions (primarily in China) that rely heavily on coal-based power (either directly or for the purpose of load balancing). Alex de Vries, a bitcoin specialist at PwC, estimates that the current global power consumption for the servers that run bitcoins software is a minimum.55 gigawatts (GW which amounts to energy consumption of 22 terawatt-hours (TWh) per yearalmost the same as Ireland. Based on 100 of revenues already being used to cover electricity expenses, the Energy Consumption Index would thus predict little change in Bitcoins energy consumption. Its true that bitcoin may face competition from other cryptocurrencies, but almost all its competitors use essentially the same wasteful mining system it does. With the help of these numbers, it is possible to compare both networks and show that Bitcoin is extremely more energy intensive per transaction than visa (note that the chart below compares a single Bitcoin transaction to 100,000 visa transactions).
Sustainability The continuous block mining cycle incentivizes people all over the world to mine Bitcoin. This provides strong support for using the economic model underlying the Bitcoin Energy Consumption Index for creating both live and predictive (which is completely impossible based solely on a bottom-up approach) estimates of Bitcoins energy consumption. The more electricity you burn, and the faster your computer, the higher your chance of winning the competition. Once one of the miners finally manages to produce a valid block, it will inform the rest of the network. Other miners will accept this block once they confirm it adheres to all rules, and then discard whatever block they had been working on themselves. The code includes several rules to validate new transactions. In the end, theres only one real reason why bitcoins energy consumption would fall, and that is if the price of the currency drops. If it keeps increasing at this rate, Bitcoin mining will consume all the worlds electricity by February 2020. Why does bitcoin require so much energy to make something that exists only electronically?
A simple bottom-up approach can now be applied to verify that this indeed happened. Bitcoin could potentially switch to such an consensus algorithm, which would significantly improve sustainability. The map above shows which countries consume less electricity than the amount consumed by global bitcoin mining. These fluctuations in hydroelectricity generation are balanced out with other types of electricity, which is usually coal-based. Instead, the geographic distribution of mining facilities in Coinshares report is based on the common belief that most Bitcoin mining still takes place in China, several announcements of mining projects, and the work of Hileman and Rauchs from 2017. Even so, the overall trend appears to be little change in the localization of miners. Unlike some other sources it includes, residential, commercial and industrial use, so may be higher than other figures"d elsewhere. The map at the top of the page shows, which countries currently consume more or less electricity than that consumed by global Bitcoin mining. According to visa, the company consumed a total amount of 674,922 Gigajoules of energy (from various sources) globally for all its operations. Also, many exchanges have failed to register, as required, with Americas Securities and Exchange Commission (SEC so could be forced to stop operating, further reducing liquidity. If that growth rate were to continue, and countries did not add any new power generating capacity, Bitcoin mining would: Be greater than UK electricity consumption by October 2018 (309 TWh) Be greater than US electricity consumption.
Electricity consumption data mostly comes from the CIA via Wikipedia and is mostly for 2014, since thats the most recent year available. It can buy few items or services, and its exchanges are constrained by their cash reserves. Thats commensurate with CO2 emissions of 20 megatonnes or roughly 1m transatlantic flights. Recall that the required number of zeros at the beginning of a hash is tweaked biweekly to adjust the difficulty of creating a blockand more zeros means more difficulty. Since electricity costs are a major component of the ongoing costs, it follows that the total electricity consumption of the Bitcoin network must be related to miner income as well. Currently they get.5 bitcoins (worth around 85,000) and about 1,000 in transaction fees.
These facilities require significant cooling capacities (not reflected in the networks computational power and therefore their PUE could easily be around.25 as motivated in the same paper. You can read about their assumptions here. Since then, its demands have only grown. If they took over pole position, it would be out of the frying pan and into the fire. Miners are obliged therefore to keep upgrading in order to earn rewards as fast as competitors. Number of Britons who could be powered by bitcoin mining:.1 million (more than the population of Birmingham, Leeds, Sheffield, Manchester, Bradford, Liverpool, Bristol, Croydon, Coventry, Leicester Nottingham combined) Or Scotland, Wales or Northern Ireland. On January 22, 2019, the Bitcoin Energy Index was estimating that 100 of miner revenues (2.3B) were actually spent on electricity costs. The Bitcoin algorithm adds these zeros in order to keep the rate at which blocks are added constant, at one new block every 10 minutes. (One major competitor, Ethereum, has long discussed moving to a proof-of-stake system, which would radically change its power use for the better, but the switchover still hasnt happened. In November, the power consumed by the entire bitcoin network was estimated to be higher than that of the Republic of Ireland.
State Total retail sales (MWh) Bitcoin Mining Consumption Relative To State's Use Alabama 88,845,543.00 33 Alaska 6,159,204.00 472 Arizona 77,349,416.00 38 Arkansas 46,465,154.00 63 California 261,170,437.00 11 Colorado 54,116,046.00 54 Connecticut 29,476,155.00 99 Delaware 11,498,205.00 253 District of Columbia 11,291,233.00 257 Florida. The lack of any central authority makes bitcoin remarkably resilient to censorship, corruption or regulation. Bitcoin can only be used as a medium of exchange and in practice has been far more important for the dark economy than it has for most legitimate uses. However, that assumes Bitcoin mining is occurring in places with cheap electricity (not an unreasonable assumption). If Bitcoin miners were a country theyd rank 61st in the world in terms of electricity consumption. Another correction would be required for the simple fact that Bitmain (with a claimed market share of around 70 ) is not the sole producer of Bitcoin mining machines, and for the fact that they were also selling less efficient. Since machine investments can be considered sunk costs (no longer relevant to the decision to continue mining miners will continue to run their machines up until the point where the electricity costs exceed the amount of mined income (approaching 100). Cryptocurrency miners seek results to a kind of algorithmic puzzle that fits a very specific set of requirements. Households powered for 1 day by the electricity consumed for a single transaction.23. Every ten minutes on average, a server finds an acceptable solution, and the miner gets a reward from the bitcoin system. Mr de Vries believes he has a good picture of the point at which bitcoin mining stops being profitable for those involved, by factoring in the cost of data centres, electricity and servers that need constant upgrading. By applying the emission factors of the respective countrys grid, we find that the Bitcoin network had a weighted average carbon intensity of 475 gCO2eq per kWh consumed. But in the zero-sum game of bitcoin mining, that just means a miner can afford to run more machines at the same time, leaving their power usage roughly stable.
