Why Does Crypto Use So Much Energy?

A close look at the power-hungry cryptocurrency industry and its impact on the environment.

Cryptocurrency is Energy-Intensive

Cryptocurrency requires a lot of energy to run. The proof-of-work system used by most cryptocurrencies (including Bitcoin) is an energy-intensive process. Cryptocurrency mining is an energy-intensive process that is used to secure the network and verify transactions. This process uses a lot of energy because it is computationally intensive.

Mining is Energy-Intensive

Cryptocurrency mining is an energy-intensive process of verifying blockchain transactions and adding them to the public ledger. In order to mine cryptocurrencies, miners need to solve complex mathematical problems that require significant computing power. The more miners that are competing to solve the next block, the more difficult the problem becomes.

As a result, cryptocurrency mining requires a lot of electricity to power the computers that are solving these complex mathematical problems. In fact, a recent study estimates that cryptocurrency mining uses more than two times as much energy as gold mining.

While some argue that this is a necessary trade-off to ensure the security of the blockchain, others believe that there needs to be more emphasis on making cryptocurrency mining more energy-efficient. Otherwise, it could become a major contributor to climate change in the years to come.

Cryptocurrency Uses More Energy Than Traditional Banking

Cryptocurrency mining is an energy-intensive process that uses high-powered computers to solve complex mathematical problems. The reward for solving these problems is newly minted cryptocurrency. As the price of cryptocurrency increases, so does the incentive for miners to solve more problems, which in turn requires more energy.

Traditional banking systems use energy too, but not nearly as much as cryptocurrency mining. For example, according to a 2018 report from the Bank for International Settlements (BIS), the annual electricity consumption of the entire banking sector was about 22 terawatt-hours (TWh). In comparison, one estimate put the annual electricity consumption of cryptocurrency mining at 62 TWh in early 2018 – meaning that crypto used nearly three times as much energy as traditional banking.

There are a few reasons why cryptocurrency consumes so much more energy than traditional banking. First, crypto mining requires specialized hardware that uses a lot of electricity. Second, crypto miners are often located in countries with cheap electricity, which means they can “mine” 24 hours a day without incurring high costs. And third, unlike banks, there is no centralized authority overseeing cryptocurrency mining – meaning that there is no one to regulate or limit the amount of energy that miners use.

Despite its high energy consumption, many people believe that cryptocurrency is a more efficient way of conducting financial transactions than traditional banking. For example, crypto doesn’t require physical bank branches or ATMs, which saves on infrastructure costs. And because crypto transactions are digital and peer-to-peer, they can be completed faster and with lower fees than traditional bank transfers.

The Energy Use of Cryptocurrency is Controversial

Cryptocurrency is a digital or virtual asset that uses cryptography for security. Cryptocurrency is decentralized, meaning it is not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009. Cryptocurrency uses a lot of energy because the process of “mining” for cryptocurrency requires a lot of computational power.

Some People Believe That Cryptocurrency is Not Worth the Energy Use

Critics of cryptocurrency argue that the high energy use of some digital currencies is wasteful and contributes to climate change. They also point out that the energy needed to mine these currencies could be better spent on more productive endeavors.

Cryptocurrency defenders counter that the energy used to mine digital currencies is no different than the energy used to power any other type of computer network. They also argue that the mining process provides valuable security for all users of the currency.

The debate over the energy use of cryptocurrency is likely to continue as more people begin to mine and use these digital currencies.

Others Believe That the Energy Use of Cryptocurrency is Worth It

Others believe that the energy use of cryptocurrency is worth it. They argue that the processing power needed to keep the system secure and running smoothly is a worthy investment, and that cryptocurrencies could one day replace traditional systems like banks. They also believe that the decentralization of power that comes with cryptocurrency could help to prevent corruption and fraud.


Crypto uses a lot of energy for two main reasons. First, the process of mining creates new coins and verifies transactions. Second, crypto runs on a decentralized network of computers, which requires a lot of energy to run.

The Energy Use of Cryptocurrency is Likely to Continue

The use of cryptocurrency has been criticised for its high energy consumption. A single transaction can use as much energy as a households worth of electricity for an entire day. In fact, the entire cryptocurrency network uses more energy than the Republic of Ireland. It is estimated that by the end of 2019, the network will use about 7.67 gigawatts of electricity, which is equal to 0.5% of the world’s total electricity consumption.

There are several reasons for this high energy consumption. First, cryptocurrency requires a lot of computing power in order to verify and record transactions on the blockchain. Second, because there is no central authority, all transactions must be verified by the network itself, which requires a lot of computing power. Third, new bitcoins are created through a process called “mining” which also requires a lot of computing power.

As the price of bitcoin and other cryptocurrencies has risen, so has the demand for mining equipment. This has led to an increase in energy consumption as more and more people race to mine bitcoins. It is estimated that China accounts for 77% of all bitcoin mining activity, and that China also consumes more electricity than any other country in the world.

Given all of this, it seems unlikely that the energy use of cryptocurrency will decrease anytime soon. In fact, it is likely to continue to increase as more people invest in cryptocurrency and demand for mining equipment increases.

The Controversy Over the Energy Use of Cryptocurrency is Unlikely to Go Away

Cryptocurrency is a controversial topic. The currency itself is not regulated by any government or financial institution, and it is not backed by any physical commodities. Cryptocurrencies are created through a process called “mining,” which involves using computer power to solve complex math problems. The first cryptocurrency, Bitcoin, was created in 2009. Since then, hundreds of other cryptocurrencies have been created.

The amount of energy that is required to mine cryptocurrency has become a controversial issue. Some estimate that the current global energy consumption for cryptocurrency mining could be equivalent to the annual energy consumption of the Netherlands. Others argue that these estimates are overblown and that the real energy consumption is closer to that of Ireland.

There are two main reasons why cryptocurrency mining uses so much energy. First, the math problems that need to be solved in order to create new units of cryptocurrency get more and more difficult as time goes on. This means that more and more computer power is needed in order to stay competitive in the mining market. Second, most cryptocurrencies are mined using specialized hardware that is designed to be as efficient as possible at solving these math problems. This hardware requires a lot of electricity in order to run properly.

The controversy over the energy use of cryptocurrency is unlikely to go away anytime soon. However, it is important to put this issue into perspective. The total amount of energy used by the global financial system – including all banks, stock exchanges, and other financial institutions – is estimated to be around 100 times higher than the current energy use of cryptocurrency mining. In other words, even if the entire global cryptocurrency mining industry was shut down tomorrow, the effect on global energy use would be less than 1%.
