Visualizing the Power Consumption of Bitcoin Mining

Crypto farm in China Source: Quartz. Bitcoin and other cryptocurrencies have been slated as the future of finance. But what's typically overlooked is the non-virtual side of Bitcoin transactions—its energy consumption. What are some solutions to address these impacts? Simply put, cryptocurrencies like Bitcoin replace payments intermediation with an open network of independent users, or "miners", who compete to validate transactions.

Their majority agreement is required for any transaction to be approved. Their goal is to add individual blocks to the blockchain by solving complex mathematical problems. Computing the correct value to satisfy the hash function in the blockchain is called "mining". Ultimately, a reward, in the form of cryptocurrencies, is given to whoever solves for the correct value.

Oftentimes, people would pool their computing power together and split the reward when they solved for the correct value. If one can accumulate enough computing power, they can solve for the value more efficiently and, in turn, acquire a substantial amount of cryptocurrency. In traditional transactions, payment networks like Visa or Mastercard typically have large corporate structures and distribute a lot of resources to facilitate these transactions.

While many think that there's no cost attached to cryptocurrency transactions, that is not the case when taking its environmental impact into consideration—Cryptomining, as mentioned above, is extremely energy-intensive.

Special computers used for mining Bitcoin are required to be high-powered enough to solve complex computational math problems. The share of electricity costs in all cryptomining costs is around 60 to 70 percent ;. Bitcoin accounts for 0. The annual carbon footprint of Bitcoin is The annual electricity consumption of Bitcoin is greater than the total energy required to power all the tea kettles in the UK for 19 years;.

If compared to other countries, Bitcoin would be ranked the 40th highest energy-consuming country in the world, above Colombia and the Czech Republic;. A single Bitcoin transaction consumes more energy than , Visa transactions and could power the average US household for a month. It also generates the CO2 equivalent to over , swipes of a Visa card;. Mining one Bitcoin usually consumes MWh Megawatt-hours of electricity, which is the same amount of electricity used to watch contents on a 65'' Samsung 4k Smart TV continuously for 98 years.

In addition, the amount of Bitcoin released is halved around every four years, making the supply more scarce and the coin more valuable over time. However, this makes cryptomining more expensive and time-consuming for miners, increasing its total energy consumption even further. Moreover, thousands of cryptocurrencies are currently in use in addition to Bitcoin. It's difficult to determine the exact carbon footprint of cryptocurrencies because of their volatility, but various organizations have given their estimates.

Coinshares, a cryptocurrency asset management firm, claims that In recent years, a growing number of crypto farms are transitioning to sustainable energy. For example, in Iceland, many crypto farms are built due to their lower power costs and lower temperatures to cool the computers. Their electricity is mostly generated from renewable geothermal sources, which also emit much lower amounts of carbon than coal or gas-powered plants.

Quebec, Canada is another favorite location for miners. While the overall environmental impact of hydropower is contested, there is an agreement that its carbon footprint is a fraction of those of gas- and coal-fired plants. Canada has also recently implemented a nationwide cap-and-trade scheme in a bid to price carbon emissions.

Because electricity prices vary widely across countries, miners tend to locate in countries where electricity is comparably cheap, since Bitcoin price is the same worldwide.

One kilowatt-hour of electricity in China, reportedly the location of 80 percent of Bitcoin mining capacity, costs 8. In contrast, in countries like Sweden, which has a carbon tax of approximately more than euros per metric ton of CO2, cryptomining would be less profitable. Researchers have also suggested that more direct taxation of mining could be beneficial to reducing the total emission of cryptomining.

Regardless, the environmental impact of electricity-intensive cryptocurrencies like Bitcoin depends heavily on the energy policies where the mining takes place. Under this premise, the higher the price of Bitcoin goes, the more competition there is for mining.

Hence, the electricity consumption of Bitcoin is only likely to increase over time due to this mechanism. This mechanism is far less energy-intensive. The amount of energy wasted on idle home devices like phone chargers and microwaves in the U. There are various proposals where miners started to utilize excess energy that was initially going to waste.

Instead of wasting this power, a hyper-mobile fleet of hardware miners can come in and out and take advantage of that excess power. While there are various solutions to address the issue regarding cryptomining's energy consumption, many are asking the question—Ultimately, is cryptomining necessarily a bad use of energy? One mainstream argument is that energy use in itself is not bad. For example, sending texts on our cell phones and storing emails on our personal laptops also use energy.

However, we rarely infer email or digital applications to be bad because they consume energy. Another argument is that Bitcoin is transparent in its energy use while other traditional industries like banking are much more opaque.

While they have the potential to be the future of finance, one thing is certain: if they are here to stay, the global energy consumption will increase significantly. With the impact of the climate crisis worsening, the tradeoff between the benefits of cryptocurrencies and their environmental costs should be brought to attention.

How one of South America’s biggest dams became a Bitcoin battleground

February 14, By Andrew Lyle. A new algorithm developed by U of A computing scientists could reduce the time and energy it takes to perform the complex computations involved in mining Bitcoin. Photo: Getty Images. A new algorithm by computing scientists at the University of Alberta could be the first step in reducing the massive amounts of energy and computing power it takes to mine cryptocurrencies like Bitcoin. Chowdhury explained that the electrical power needed to perform the computation has a massive carbon footprint-a growing concern for the Bitcoin mining industry. The researchers' new technique takes on a computational problem known as the Boolean satisfiability SAT problem, which is well known in computing science and has applications in hardware design, software testing and encryption-and Bitcoin mining. Chowdhury noted the algorithm is still in its early stages and will need more research and tailoring before it can be used in the industry, but early results are promising. One of our submitted solvers made it to the top tier competing against other state-of-the-art approaches," he said. Science and Technology.

Cryptocurrency mining is very easy to understand. This consists of verifying the transactions made between people who exchange cryptocurrencies, including the most famous which is Bitcoin, using very powerful computers. Indeed, by nature, there is no bank in the cryptocurrency universe to perform this kind of verification. So miners are needed.

Riot Blockchain, Inc. Castle Rock, Colorado. The current global shortage of ASIC mining equipment has held the current network-wide hash rate at lower levels, creating a beneficial mining environment for miners currently operating, especially those operating at scale. The Company currently plans to provide recurring monthly operational updates and unaudited production results through the end of Once deployed, these 1, miners, combined with the additional 25, miners scheduled to be received during under previously announced purchase orders, are expected to achieve an estimated aggregate bitcoin mining hash rate capacity of 4.
