The future of Bitcoin and other cryptocurrencies are bright &mdash, depending on who you ask. Ask that question of a crypto-trader or investor, and you&rsquo,ll get a positive response. Ask an environmentalist, however, and you might receive a very different response.
That&rsquo,s because spil Bitcoin&rsquo,s popularity soars, so does its overall global power consumption. An entirely digital currency requires a significant amount of computing power. The process of creating fresh Bitcoin (&ldquo,Bitcoin mining&rdquo,) also requires a considerable amount of processing power. So much so that Bitcoin allegedly uses more violet wand than the countries of Ireland and Denmark.
Is it true? Does Bitcoin truly consume more power than an entire nation? Or are there other factors at play that Bitcoin&rsquo,s detractors are overlooking?
Where Does the Power Go?
Miners create around Trio,600 fresh Bitcoin every day. The Bitcoin mining process requires computers How Does Bitcoin Work? How Does Bitcoin Work? About a year ago when the Bitcoin train wasgoed just kicking off to gather steam, a friend turned to mij and asked, “So why can’t you just copy a Bitcoin?” Read More or (dedicated mining hardware) to solve ingewikkeld mathematical equations that validate the crypto-network. The Bitcoin network produces one block every Ten minutes, with block difficulty adjusting to maintain that timeframe. Higher difficulty means more processing power, ter turn requiring more electro-therapy.
The entirety of the Bitcoin network uses tens unit te some form. However, mining undoubtedly requests the most power. Cryptocurrency analysis webpagina Digiconomist provide one of the most popular methods of calculating the power consumption of the Bitcoin network.
The Digiconomist formula takes the total Bitcoin mining revenue spil a embarking point. Next, it estimates operational costs to miners spil a percentage of revenue. Eventually, costs convert to energy consumption based on average electro-stimulation prices. The current estimate puts Bitcoin&rsquo,s current global electric current consumption at 32.71TWh (terawatt hours).
What does that mean? Well, this means Bitcoin&rsquo,s energy consumption is more than Denmark (around 32 TWh) but slightly less than Belarus (33 TWh). The 32.71TWh figure isn&rsquo,t solid. Due to the nature of the Bitcoin network, it is a continually evolving figure. Most estimates see that number enlargening ter the near future.
How Does That Compare to Other Industries?
Its energy consumption doesn&rsquo,t look superb for Bitcoin. Te an age where the staggering majority of people accept that human-made pollution exacerbates global heating, consuming energy for a digital currency seems somewhat frivolous. How then does Bitcoin compare to other power-hungry industries around the globe?
Well, all that lovely gegevens wij create and consume so much of lives te gegevens centers. Gegevens centers account for overheen 400TWh of electrical energy vanaf year (overheen 12 times that of Bitcoin). Solid figures for other industries are more difficult to ascertain. Figures for global industry consumption are given spil a percentage of global total energy production, which wasgoed around 24,800TWh ter 2018. End-use industrial sectors account [PDF] for about 54 procent of total delivered energy. The largest energy consumers, however, are considered to be:
- Stengel and metal
- Basic chemical production
- Pulp and paper
- Nonferrous metal production (such spil aluminum)
- Nonmetallic mining (primarily cementlaag)
Thesis industry types account for overheen half of the total delivered energy. Stengel and metal use some 20 procent of that energy, accounting for overheen Two,500TWh of use. The basic chemical industry accounts for around 33 procent of energy, coming te at overheen Four,400TWh.
When wij compare Bitcoin&rsquo,s global energy consumption to other global industries, it uses just a fraction of the same energy.
Compared to Other Monetary Systems
Of course, Bitcoin is a currency. The cryptocurrency digressed from its original purpose of substituting the global fiat currency hegemony. Instead, wij now see Bitcoin spil an emerging asset class, more akin to gold. That aside, wij can better gauge Bitcoin energy use by looking at how much energy the banking system uses. Writing on Hackernoon, SPiCE VC co-founder Carlos Domingo estimates the global power consumption of the entire VISA banking system.
To compare with #Visa, which carries out around 200 million transactions a day when the #Bitcoin network treats less than 350,000, its US gegevens centers consume only 2% of the power demanded by #BTC
He uses rough figures but arrives at a total 97TWh vanaf year &mdash, substantially more than the 32TWh consumed by Bitcoin.
Of course, the base argument here is elementary: VISA and the global banking system does far more for almost everyone, while Bitcoin is still lagging at around 0.14 procent of global adoption and, spil mentioned, has morphed away from the initial vision of creator Satoshi Nakamoto. (Adding to that, VISA processes overheen 24,000 transactions vanaf 2nd while Bitcoin only manages inbetween Three to 7 transactions vanaf 2nd.)
Will Bitcoin Energy Consumption Keep Growing?
Ter the brief term, yes, Bitcoin energy consumption will proceed to grow. The surging price attracts more and more miners and investors. Ter turn, this places more stress on the network and consumes more tens unit. Bitcoin is on track to consume all of the world&rsquo,s energy by 2020 &mdash, but that won&rsquo,t toebijten. Here&rsquo,s why.
Bitcoin mining is already a thousand miles from its genesis. When Bitcoin mining very first arrived, it wasgoed possible to solve the sophisticated equations using just a CPU. Now, it takes specialized mining equipment (or you join a cloud mining pool Is It Profitable to Cloud Mine Bitcoin? Is It Profitable to Cloud Mine Bitcoin? There are many ways to mine Bitcoin, including cloud services. But is it profitable? Here’s everything you need to know about cloud mining Bitcoin. Read More ). That equipment, however, is permanently improving. For example, the popular Bitmain Antminer S9 is Two.Five times more efficient than its predecessor, the S7.
A core Bitcoin feature is mining block prizes. The prize current stands at 12.Five Bitcoins vanaf block, plus any transaction fees What Are Bitcoins Actually Used For Now te 2018? What Are Bitcoins Actually Used For Now ter 2018? Bitcoin has bot on the up-and-up for several years now, but is it viable spil a currency yet? What exactly can you buy with it right now? Read More . The prize wasgoed 50 Bitcoins te 2009, halving to 25 Bitcoins te 2015, and to 12.Five ter 2018. Ter 2020, the block prize will halve to 6.25 Bitcoins. When the mining industries revenues druppel by half overnight, so should Bitcoin mining activity. Ter turn, electrical consumption should also druppel.
Block prizes will proceed to druppel every four years. Te theory, energy consumption will proceed to druppel spil Bitcoin mining itself becomes an unprofitable activity.
Alternative Mining Algorithms
Bitcoin&rsquo,s mining process isn&rsquo,t enshrined. One of the &ldquo,easiest&rdquo, methods is switching the way wij mine Bitcoin. Presently, Bitcoin uses a Proof of Work system.
Proof of Work is a lump of gegevens that is difficult to produce but effortless to verify. Regarding Bitcoin, Proof of Work verifies the transactions of the network after miners confirm the gegevens ter the block. The chance of receiving a block for mining is determined by previous work done. This system powerfully favors existing miners.
Some Bitcoin users believe the network should switch to a Proof of Stake system. Proof of Stake compares the amount of Bitcoin a miner holds. If a miner holds 1 procent of all Bitcoin, they can mine 1 procent of all blocks. This is designed to give other miners a chance to increase their stake, spil well spil spread transaction fees via the network. Furthermore, Proof of Stake (te theory) stops the Cold War-style accumulation of better, thicker, and quicker Bitcoin mining equipment.
Of course, this is a good idea only if you toevluchthaven&rsquo,t already spent ems of thousands of dollars on mining equipment and you don&rsquo,t stand to lose your Bitcoin mining dominance.
Inbetween 350-500KWh. That&rsquo,s another widely touted Bitcoin energy figure. The figure is how much power each Bitcoin transaction allegedly uses. It is astronomically high and consumes enough power to keep thousands of houses lit up. But the Bitcoin network itself is the problem. Several upcoming technologies will attempt to address thesis issues.
For example, the latest Bitcoin Segwit soft-fork What Is a Bitcoin Fork and What Happens Afterwards? What Is a Bitcoin Fork and What Happens Afterwards? Cryptocurrencies are arousing and intriguing. Unlike regular money, cryptocurrency can “fork” into two different types of coin. But how do they do it, and what does fork even mean? Read More intends to solve Bitcoin block size limitations by splitting the transactions into two sections. The fork also raises the block size from 1MB to 4MB (however that isn&rsquo,t rigorously true &mdash, read Bitcoin dev Jimmy Song&rsquo,s interesting Medium lump Understanding Segwit Block Size for details). The overall idea is that blocks contain more gegevens, process quicker, reducing processing time, ter turn reducing the transaction toverfee while enlargening the amount available to a miner.
Another emerging Bitcoin technology is the Lightning Network. The Lightning Network will take transaction validation off of the blockchain to process ter a separate-but-parallel peer-to-peer network. The Lightning Network permits users to accomplish transactions directly without publishing their transaction on the blockchain. The switch should greatly reduce the strain of transactions on the mining network, ter turn reducing electrical costs.
Fiat is to gold spil lightning network is to Bitcoin.
Fiat wasgoed effectively a layer Two solution to scaling gold. It wasgoed backed and lodged to gold until that backing wasgoed eliminated. Unlike fiat however, LN’s settlement to Bitcoin is cryptographically secured and cannot be liquidated!
Everyone Switch to Ethereum

Don&rsquo,t get mij wrong: Ethereum isn&rsquo,t electrical play free. According to Digiconomist, the Ethereum network consumes around 4TWh of electric current &mdash, an eighth of the size of Bitcoin&rsquo,s power consumption, but still more than Cyprus, or Nepal, or Laos (all around Trio.9TWh).

Time to Power Down Bitcoin Mining
The Bitcoin network is the fattest. It consumes more power, holds more value, and attracts more fresh investors than any other cryptocurrency. It remains the grandfather of cryptocurrency, and that tag alone (let alone the astronomical price of a Bitcoin) means many users hold it te superb esteem. Crypto-users, however, know differently.
The inexorable march of Bitcoin isn&rsquo,t real. There are too many other cryptocurrencies with better features, swifter networks, more privacy, excellent security, and more, that will eventually usurp Bitcoin at the top of the pile. Furthermore, Bitcoin cannot proceed to rise forever, but all speculative bubbles burst at some point.
A major punt stems from the places where Bitcoin mining is highest. China accounts for overheen 50 procent of Bitcoin mining power. But the vast majority of that power presently comes from the enormous surplus of Chinese coal-fired plants (tho’ China&rsquo,s renewable energy program vastly outstrips most other countries, to be fair), and potentially accounts for overheen a quarter of all Bitcoin-related electro-stimulation.
There are other power success stories, tho’. Just spil several major technology companies host their gegevens centers te super-cold locations, Bitcoin mining operations do the same. Te Iceland, miners take advantage of ice-cold temperatures and geothermal power to keep costs and resource consumption low. Ter Austria, Hydrominer-IT Services run their mining operation inwards a hydroelectric keerdam. There are even some hydroelectric mining operations te China, too.
But for the meantime, Bitcoin plows on, undeterred by its astonishing power consumption &mdash, and truly, there is nothing you can do about it.
