Many people are positive on [crypto-currencies](https://yourviews.mindstick.com/view/82876/cryptocurrency-and-its-scope-in-india) like Bitcoin, but critics point out a significant drawback: crypto-currency mining consumes a lot of energy. While there are other ways to verify crypto-currency transactions and create new coins, **the two most popular crypto;currencies, Bitcoin and Ethereum, use mining as their primary mechanism**. ![Is block-chain technology damaging for the environment?](https://answers.mindstick.com/questionanswer/033764fb-d43c-42e5-9e56-eb2908fdfbe5/images/65d443ea-54f4-434d-8e40-cffc2bdc3d5f.png) The amount of energy consumed for Bitcoin and cryptocurrency mining cannot be calculated directly, but it can be inferred from the network's hashrate and the amount utilised by mining rigs that are readily accessible for purchase. **The Energy Consumption Of Crypto-Currencies.** Using the most recent country energy estimates from 2019, the Cambridge Bitcoin Electricity Consumption Index calculates that [Bitcoin](https://yourviews.mindstick.com/view/82555/crypto-coins-vs-tokens-what-s-the-difference), the most widely-mined cryptocurrency network, used an estimated 85 Terawatt-hours (TWh) of electricity (0.38% of global electricity use) and roughly 218 TWh of energy (0.13% of global energy production) at the point of production. This is more than Belgium and Finland combined. Based on energy use through July 9, 2022, the figure is estimated to be 130.3 Terawatt-hours by the cryptocurrency analytics website **Digiconomist**. This amounts to roughly 1455.8 kilowatt-hours of electricity used for each transaction, or about the same as what the typical American home uses in **49.9 days**. Disclosed energy usage through July 9, 2022 of Ethereum is projected to use more than 60 Terawatt-hours of electricity year, which is comparable to Switzerland's electricity consumption. A typical **Ethereum transaction used 163 kilowatt-hours of electricity, which is equivalent to the amount used by a typical American household in 5.51 days**. **The proof-of-stake consensus mechanism was implemented by Ethereum developers as a solution, but it is still in the testing stage. Assuming that prices and user acceptance continue to fluctuate, the amount of energy used by bitcoin mining will probably change over time.** The incentive to start mining also rises as the value of the block reward does, making cryptocurrency mining a competitive activity. More energy is used by cryptocurrency networks as a result of higher cryptocurrency values. **Conclusion.** It is more difficult to determine the carbon impact of crypto-currencies. Although the majority of the nations where crypto-currencies are mined use fossil fuels as their main energy source, miners must look for the most affordable energy sources in order to stay profitable. That frequently entails utilising fresh alternative energy installations.

It has become increasingly popular in recent years due to its many benefits, such as increased security, transparency, and efficiency. However, there are concerns that blockchain technology may be damaging for the environment. One of the main environmental concerns associated with [blockchain technology is its energy consumption.](https://www.mindstick.com/articles/279823/measure-monitor-and-manage-your-energy-consumption-with-iot) Blockchain networks require a significant amount of computational power to operate, which in turn requires a lot of energy. The process of verifying transactions on a blockchain network, known as mining, involves solving complex mathematical problems that require a lot of computational power. This process requires a significant amount of energy, much of which comes from non-renewable sources such as coal and natural gas. ![Is block-chain technology damaging for the environment?](https://answers.mindstick.com/questionanswer/033764fb-d43c-42e5-9e56-eb2908fdfbe5/images/363a35ff-ce27-41f6-86cb-5de551b9c2e0.jpeg) Another concern is the use of hardware equipment such as [graphics processing units (GPUs)](https://answers.mindstick.com/qa/97212/explain-the-motherboard-supported-feature-integrated-graphics) and application-specific integrated circuits (ASICs) for mining. These devices consume a lot of energy and can quickly become obsolete, leading to a high turnover rate of hardware and electronic waste. The environmental impact of blockchain technology is not limited to energy consumption and electronic waste. The production of the hardware used for mining and other blockchain operations requires the extraction and processing of raw materials such as metals and minerals, which can have negative environmental impacts such as soil degradation, water pollution, and deforestation. Furthermore, the increasing popularity of blockchain technology has led to the proliferation of cryptocurrencies such as Bitcoin and Ethereum, which have been associated with high levels of carbon emissions. The Cambridge Bitcoin Electricity Consumption Index estimates that the Bitcoin network currently consumes around 111.73 terawatt-hours (TWh) of electricity per year, which is roughly equivalent to the annual electricity consumption of a country like Argentina. To mitigate the environmental impact of blockchain technology, several solutions have been proposed. One solution is to develop more energy-efficient consensus algorithms, such as proof-of-stake, which requires significantly less computational power than proof-of-work. Another solution is to use renewable energy sources for blockchain operations, which would help reduce greenhouse gas emissions and reliance on non-renewable energy sources. Additionally, efforts can be made to reduce electronic waste by increasing the lifespan of mining equipment or developing more sustainable hardware solutions. --- Original Source: https://answers.mindstick.com/qa/98087/is-block-chain-technology-damaging-for-the-environment Copyright © MindStick Software Pvt.
