Bitcoin’s Energy Consumption Explained
The Bitcoin digital currency is a digital currency operated by multiple computers around the world working to maintain the Bitcoin digital currency blockchain, a public database of all transactions on a worldwide network. Bitcoin digital currency miners compete to officially record and verify transactions and earn bitcoin digital currency as a reward.
The Digital Currency Bitcoin These transactions are verified by solving complex cryptographic and mathematical problems for which bitcoin digital currency miners use a great deal of power. Together, the bitcoin digital currency uses more electricity than many countries. Here’s a look at how much power it takes to create a new bitcoin digital currency and how much power the bitcoin digital currency network uses daily.
- Computers that record and verify bitcoin digital currency transactions consume electricity at a level similar to that in some countries.
- The exact amount of electricity used by bitcoin digital currency transactions can vary depending on demand.
- The environmental impact of the bitcoin digital currency network depends on electricity consumption, the type of energy powering the bitcoin digital currency network, and the electronic waste it generates.
Why Do Bitcoin Transactions Require Energy?
Solving complex problems requires a fair amount of computational power and, in theory, almost any computer can be used to mine the bitcoin digital currency. In reality, however, high competition makes it difficult to profit unless you have a purpose-built bitcoin digital currency mining setup and relatively cheap electricity.
The more computing power you have, the higher your chances of solving calculations and earning bitcoin digital currency mining rewards. This encourages bitcoin digital currency miners to buy more powerful computers to achieve higher hash rates.
Note:- The hash rate is a measure of how fast a computer is working on mining the digital bitcoin currency, usually calculated per second. For example, 1 hash/s indicates that 1 million hash calculations are performed every second.
But even larger, more powerful computers can require more power from the power grid, making the overall mining network a huge energy hog. There are four main factors in how much electricity a bitcoin digital currency miner uses:
- Hardware computing power
- Network hash rate
- Mining difficulty
- Thermal regulation for the hardware
If you are mining yourself for the bitcoin digital currency, you can reduce your energy use with a more efficient miner or choose a currency that is less competitive to mine.
How Much Energy Does the Bitcoin Network Consume?
How much power does it really take to create a bitcoin digital currency? According to Digiconomist, as of September 15, 2022, a single bitcoin digital currency transaction requires 1,390.49 kWh, which is roughly equivalent to the consumption of electricity for an average American household for 48 days. The annual energy consumption of the bitcoin digital currency is estimated to be 129.47 TWh a year, or the same amount of electricity used annually in Sweden

The annual energy consumption of the bitcoin digital currency is estimated to be 129.47 TWh a year, or the same amount of electricity used annually in Sweden.
Note:- A separate estimate from the University of Cambridge estimated the annual energy use of the bitcoin digital currency to be about 94.82 TWh, about 0.42% of the total electricity used on Earth, and roughly slightly more than the annual electricity consumed by Kazakhstan as of September 15, 2022.
Here is a look at the energy consumption of the bitcoin digital currency (also at the low end of 94.82 TWh) compared to the 2019 electricity consumption of some countries based on information from the United States Energy Information Administration (US EIA)
|Country||Annual Energy Consumption (in TWh)|
Truly speaking, that’s a ton of electricity that many people, including Elon Musk, can relate to. In May 2021, Tesla’s chairman tweeted his concerns about the bitcoin digital currency’s reliance on fossil fuels and suspended the sale of Tesla cars in exchange for the bitcoin digital currency. Exactly a month later, Elon Musk tweeted that Tesla would resume bitcoin digital currency transactions once “verified (~50%) clean energy use by miners is reasonable.”
The energy used by the network can fluctuate and decrease depending on the number of miners connected to the bitcoin digital currency, the volume of transactions, and the type of computer that is doing the mining. For example, as reported by the South China Morning Post, a government crackdown in China in 2021 led to the closure of many of the world’s largest bitcoin digital currency mining operations. This bitcoin digital currency is likely to transfer mining and electricity consumption to computers outside of China, which may require varying amounts of energy.
If you are a big crypto digital currency enthusiast, you might find this energy use worthwhile. However, environmental impact is an important consideration when deciding whether to participate in the bitcoin digital currency network or a more energy-efficient alternative.
The Environmental Impact of Bitcoin Energy Consumption
The energy consumption of the bitcoin digital currency has far-reaching environmental consequences. This is not only the amount of energy needed to power its digital currency network, but also what kind of energy and electronic waste are generated in the process.
According to Digiconomist, the carbon footprint of a single bitcoin digital currency transaction in 2022 is approximately 775.56 kilograms of carbon dioxide equivalent (CO2), or roughly equivalent to the carbon footprint generated by 1,718,906 Visa transactions or 129,260 hours of YouTube video viewing. The annual carbon footprint of the Bitcoin digital currency network is 72.21 metric tons of CO2.
In the country of China, much of the electricity comes from coal-burning power plants, which have a high environmental impact. So, while most bitcoin digital currency mining took place primarily in China, it relied on a grid that was primarily powered by dirty, coal-burning power plants.
The specialized equipment required for bitcoin digital currency mining, unlike the requirements of some other cryptocurrency digital currency, cannot be reused for other tasks. It generates a huge amount of electronic waste in the form of computer hardware. According to Digiconomist, in 2022, a single bitcoin digital currency transaction would generate 410.20 grams of electronic waste or the equivalent weight of 2.50 iPhones 12 or 0.84 iPads.
Important:- Some of the components of mining equipment include trace amounts of aluminum, trace amounts of copper, trace amounts of iron, and also metals such as rare earth metals. Some issues Researchers believe that less than ideal recycling and waste collection in countries with large mining operations could pose a risk of toxic metals polluting the soil, water, and air in large quantities in those countries.
For those who stick with mining the bitcoin digital currency, it’s a great deal. The best ways to cut down on energy use include using renewable energy, such as solar or wind power, or buying the most efficient mining hardware.
Miners using application-specific integrated circuits or ASIC graphics cards may use less power per bitcoin digital currency than less efficient alternatives. The Bitmain Antminer, a popular digital currency, is an example of a cryptocurrency-specific mining computer.
Some miners of the bitcoin digital currency also rely on a combination of forces with others through “mining pools” to distribute the energy and other costs associated with mining.
Is Bitcoin Worth the Environmental Cost?
Elon Musk isn’t the only critic of the bitcoin digital currency’s electricity use. For many, including those who prefer the digital currency cryptocurrency, the environmental cost of the bitcoin digital currency can be enormous, especially in an age where people struggle with the real-life consequences of climate change. But proponents argue that the bitcoin digital currency and the crypto digital currency are worth it, as they could usher in a new era of energy usage patterns.
With upgrades in the cryptocurrency digital currency landscape, such as that performed by the Ethereum digital currency, it may be possible at some point in the future to find the best of both worlds with an energy-efficient cryptocurrency digital currency powered by renewable electricity. For today, however, mining the bitcoin digital currency has a high environmental cost. If you think electricity usage is too high, you can incorporate it into your cryptocurrency digital currency investment decisions, like Elon Musk.
