Are bitcoins worth the electricity

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.

The bitcoin network consumes vast amounts of electricity. Some researchers say most of it comes from wind, solar, and hydroelectric power. Why bitcoin needs so much power Even though bitcoin solely exists in digital zeroes and ones, the computers that run the network are huge energy hogs.

A map showing the major bitcoin mining regions around the world. Has bitcoin truly cleaned up its act? Bitcoin mining hardware is leading to a growing volume of electronic waste. Next Up In Technology. Miners can profit if the price of bitcoins exceeds the cost to mine. There are several factors that determine whether bitcoin mining is a profitable venture.

Prior to the advent of new bitcoin mining software in , mining was generally done on personal computers. This is because of the way that mining is set up: miners are competing to solve hash problems as quickly as possible, so those miners at a serious computational disadvantage essentially stand no chance of solving a problem first and being rewarded with bitcoin. When miners used the old machines, the difficulty in mining bitcoins was roughly in line with the price of bitcoins.

But with these new machines came issues related to both the high cost to obtain and run the new equipment and the lack of availability. Old timers say, way back in mining bitcoins using just their personal computers were able to make a profit for several reasons.

First, these miners already owned their systems, so equipment costs were effectively nil. They could change the settings on their computers to run more efficiently with less stress. Second, these were the days before professional bitcoin mining centers with massive computing power entered the game. Early miners only had to compete with other individual miners on home computer systems. The competition was on even footing.

Even when electricity costs varied based on geographic region, the difference was not enough to deter individuals from mining. After ASICs came into play, the game changed. Individuals were now competing against powerful mining rigs that had more computing power.

Mining profits were getting chipped away by expenses like purchasing new computing equipment, paying higher energy costs for running the new equipment, and the continued difficulty in mining. As discussed above, the difficulty rate associated with mining bitcoin is variable and changes roughly every two weeks in order to maintain a stable production of verified blocks for the blockchain and, in turn, bitcoins introduced into circulation. The higher the difficulty rate, the less likely that an individual miner is to successfully be able to solve the hash problem and earn bitcoin.

In recent years, the mining difficulty rate has skyrocketed. When bitcoin was first launched, the difficulty was 1. As of May , it is more than 16 trillion. The Bitcoin network will be capped at 21 million total bitcoin. This has been a key stipulation of the entire ecosystem since it was founded, and the limit is put in place to attempt to control for supply of the cryptocurrency. Currently, over 18 million bitcoin have been mined.

As a way of controlling the introduction of new bitcoin into circulation, the network protocol halves the number of bitcoin rewarded to miners for successfully completing a block about every four years. In , this number was halved and the reward became In , it halved again to In May , the reward halved once again to 6. Bitcoin mining can still make sense and be profitable for some individuals. In an effort to stay competitive, some machines have adapted. For example, some hardware allows users to alter settings to lower energy requirements, thus lowering overall costs.

The variables needed to make this calculation are:. Profitability calculators differ slightly and some are more complex than others. Run your analysis several times using different price levels for both the cost of power and value of bitcoins. Also, change the level of difficulty to see how that impacts the analysis. Determine at what price level bitcoin mining becomes profitable for you—that is your breakeven price.

Given a current reward of 6. Of course, as the price of bitcoin is highly variable, this reward figure is likely to change. To compete against the mining mega centers, individuals can join a mining pool , which is a group of miners who work together and share the rewards. This can increase the speed and reduce the difficulty in mining, putting profitability in reach.

As difficulty and cost have increased, more and more individual miners have opted to participate in a pool. While the overall reward decreases because it is shared among multiple participants, the combined computing power means that mining pools stand a much greater chance of actually completing a hashing problem first and receiving a reward in the first place.

To answer the question of whether bitcoin mining is still profitable, use a web-based profitability calculator to run a cost-benefit analysis.

You can plug in different numbers and find your breakeven point after which mining is profitable. Determine if you are willing to lay out the necessary initial capital for the hardware, and estimate the future value of bitcoins as well as the level of difficulty. When both bitcoin prices and mining difficulty decline, it usually indicates fewer miners and more ease in receiving bitcoins. When bitcoin prices and mining difficulty rise, expect the opposite—more miners competing for fewer bitcoins.

The software that mines bitcoin is designed so that it always will take 10 minutes for everyone on the network to solve the puzzle. It does that by scaling the difficulty of the puzzle depending on how many people are trying to solve it.

As more people join the bitcoin network and try to mine bitcoins, the puzzles become harder, and more computing power and electricity are used for each bitcoin produced. The best bitcoin mining software doesn't only allow you to operate the hardware, it also minimizes downtown allowing you to mine with a higher amount of power efficiency. To understand how to calculate the electrical energy used to power the bitcoin network, you'll need to understand how bitcoin creation works. These individual sums are called hashes, and there are vast numbers of them—so many, in fact, that you have to think of them in terms of millions of hashes known as megahashes or billions of hashes gigahashes to make any sense of them.

In early , the computers on the bitcoin network were close to exahashes per second. One terahash is a trillion hashes per second, one petahash is a quadrillion hashes per second, and one exahash is one quintillion hashes per second a one followed by 18 zeros. There are lots of different bitcoin mining computers out there, but many companies have focused on Application-Specific Integrated Circuit ASIC mining computers, which use less energy to conduct their calculations.

If this information is correct, the bitcoin network in consumes gigawatts GW per second. This converts to about 63 terawatt-hours TWh per year. This staggering amount of power is the equivalent of million horses 1. Regardless of the number of miners, it still takes 10 minutes to mine one Bitcoin. At seconds 10 minutes , all else being equal it will take 72, GW or 72 Terawatts of power to mine a Bitcoin using the average power usage provided by ASIC miners.

One watt per gigahash per second is fairly efficient, so it's likely that this is a conservative estimate since a large number of residential miners use more power. Media outlets and bloggers have produced various estimates of the electrical energy used in bitcoin mining, so the accuracy of reported power use is sketchy, at best. To perform a cost calculation to understand how much power it would take you to create a bitcoin, you'd first need to know electricity costs where you live and the amount of power you would consume.

More efficient mining equipment means less power consumption, and less power consumption means lower power bills. The lower the price of electricity, the less cost there is to miners—thus increasing the value of the Bitcoin to miners in lower-cost areas after accounting for all the costs associated with setup.

Bitcoin's exchange rate has fluctuated wildly throughout its history—but as long as it's price stays above the cost to produce a coin, doing the work in an area where energy costs are very low is important to make the practice worthwhile. The price placed on bitcoin in terms of energy consumption, and thus environmental impact, depends on how useful it's going to be to society.

This then begs the question—if bitcoin continues to rise in popularity and price, how much more power will be consumed, and will it ultimately be worth the environmental cost? Table of Contents Expand. Every blocks roughly every two weeks , the system is recalibrated. Miners are obliged therefore to keep upgrading in order to earn rewards as fast as competitors. And more computing power requires more electricity.

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. It can buy few items or services, and its exchanges are constrained by their cash reserves.

Moreover, the days of cheap electricity may not last. 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 to the national grid, making their unused power more valuable.

The value of their stake gives them a sort of voting right in how the next block is formed, as well as a return on investment for that stake. They also have to contribute computing assets, but the overall computational power required is far lower than the bitcoin approach and grows slowly over time.
